Extruded concrete sidewall construction technology has good application value in the construction of housing buildings, replacing the traditional construction process of mat chipping, overfilling and rolling, which is of great significance for the improvement of construction quality and the reduction of project costs, and is widely favored by the construction industry, thus strengthening the practical application of extruded concrete sidewall construction technology in the construction of housing buildings to perform technology and analysis, in order to promote the overall development of this technology.
1 Extruded concrete sidewall construction technology overview
Extruded concrete sidewall construction technology is based on the principle of extruded sliding film in the construction of landscape engineering, through the role of mechanical squeezing pressure to promote the formation of the wall, and then through the reaction force to promote the smooth implementation of extruded concrete sidewall construction.
In the actual construction process of the housing building, the extruded concrete sidewall construction is carried out through the sidewall machine for extrusion operation to promote the formation of concrete retaining wall, on the basis of which the dam material is laid in strict accordance with the design requirements of the housing building construction and the standardized rolling operation is carried out to ensure the smooth implementation of the concrete sidewall construction.
From the overall situation, the extruded concrete sidewall construction has good applicability, because the actual ratio of the concrete itself is more standardized, and the sidewall machine in the actual extrusion operation process of high efficiency, in this case, to promote the smooth and orderly construction, for the concrete sidewall dam surface of the balanced flat foundation, to maximize the ability of the sidewall to adapt to subsidence, effectively avoid the lower cavity may cause the impact on the panel.
2 Advantages of Extruded Concrete Sidewalls
The asymmetrical trapezoid shape is the main shape of the extruded section of the sidewall and is connected by means of articulation, which allows the sidewall to adapt well to the deformation occurring in the bedding area and effectively prevents the appearance of the cavity at the bottom due to the failure of the rolling, which effectively controls the adverse effects on the slab surface.
The technology effectively combines the joints between the bedding layer and the sidewall to make a reasonable design of the construction process, which can effectively ensure the quality of the project after rolling.
The sidewall extrusion technology simplifies the traditional construction equipment and construction process, and also greatly simplifies the construction process, which replaces the traditional construction process of slope cutting, overfilling, rolling, trimming and slope protection of the bedding layer.
The extruded concrete sidewall construction technology is simple, quick and easy to construct, and easier to master. At the same time, the extruded sidewall has a certain restrictive effect on the upstream slope, and it does not need to overfill the bedding material, and replace the original slope rolling with horizontal rolling, which not only improves the construction quality of the bedding material, but also improves the safety of construction.
It can effectively avoid the interruption of construction caused by manual reasons, which has an important role in improving the construction progress. Generally speaking, the construction speed can reach 40-80m/h with the sidewall extrusion construction technology, and the bedding material can be rolled and paved 2-3h after the sidewall is formed, and the connection between the two is tight and smooth, and even synchronous rise can be realized.
The extruded sidewall can form a flat, regular, compacted slope in the upstream wall, while the continuous sidewall forms a regular flat slope, which can play a good protection role for the bedding material and create good conditions for the construction of the panel concrete later.
3 Extruded concrete sidewall construction process
Extruded concrete sidewall construction has certain special characteristics, in the actual construction process, the relevant construction units should strictly follow the design standards and specifications for the bedding layer and extruded wall construction operations, to lay a reliable foundation for the smooth implementation of construction.
At the same time, should ensure that the actual performance of construction machinery to meet the actual requirements of the construction of extruded concrete sidewalls of housing buildings, so as to effectively control the construction quality.
3.1 Do a good job of preparation before construction.
The preparation work before construction is the basis of construction quality control, and has an important role in improving the safety of extruded concrete sidewall construction of housing buildings.
Then in the actual construction process, the relevant construction personnel should strictly follow the design requirements, the bedding paving flatness and height difference for reasonable control, to ensure that the height difference after rolling to meet the actual requirements of construction, for the parts that do not meet the construction standards, should be actively adjusted and processed to ensure that the construction standards are met before the release of construction operations.
The clear location of the line should be scientific and feasible, combined with the width of the bottom of the extrusion wall to delineate the inner position, so that the control line of the extrusion machine walking a reasonable delineation to promote the smooth progress of construction.
In addition, the construction personnel should also adjust the position of the extrusion machine, in order to ensure the standard operation of the extrusion machine, in the actual construction process, the height of the extrusion machine and the body position should be adjusted in a timely manner, so as to clarify the height of the extrusion wall, to provide a strong guarantee for the safety of the construction specification.
3.2 Side wall extrusion molding construction operation
In the process of construction operation of side wall extrusion, special personnel should be assigned to grasp the speed and efficiency of the extrusion machine, especially in the process of unloading the mixing truck, the coarse aggregate should be discarded, and the subsequent construction operation process can be carried out only after the material is evenly discharged, so as to effectively control the construction quality of the side wall of the extrusion wall and ensure the operation of the extrusion machine and The consistency of the operation of the extruder and the walking of the mixing and transporting truck, so as to effectively manage the quality of extrusion molding construction.
3.3 Practical application of sidewall concrete extrusion construction technology
3.3.1 Clean up the construction site and ensure that its levelness meets the construction requirements. .
In the actual situation of extruded concrete sidewall construction, the actual flatness of the bedding layer will have an important impact on the appearance size of the extruded concrete sidewall after forming, so it is important to strengthen the processing of the bedding layer in the sidewall concrete construction. At the same time, the relevant construction personnel should strictly check the actual flatness and height difference of the bedding material after filling in time, and for those that do not meet the construction standards, they should be trimmed and processed in time.
3.3.2 Positioning and orientation of the extruder.
Before the extruder is lifted, the performance of the extruder’s moral parts should be checked in time to ensure the effective use of its value in the sidewall concrete extrusion construction, to avoid to the greatest extent possible the impact of the construction progress due to performance failure.
3.3.3 Measuring and placing work.
Combined with the actual characteristics of the side wall concrete pressurization construction, the actual width of the extruder should be measured and placed for standard work, and the actual direction of the extruder should be guided by the standard.
3.3.4 For the extruder construction is not in place in time to repair the parts.
The construction personnel should take the way of manual mold casting to repair the places where the extruder construction is not in place, such as the interlayer collection parts, and reasonably deal with the problems of bump, vacancy and stubble between layers, so as to promote the smooth progress of construction.
3.3.5 Quality management of wall forming construction.
In the process of extruded concrete forming, the construction department should arrange special personnel to manage and control the direction of the extruder, control the walking deviation of the extruder within a reasonable range, and make timely repair for the deficiencies in construction, so as to ensure that the quality of wall construction meets the actual requirements of housing construction.
3.3.6 Filling of crushed bedding material.
The construction of bedding material is carried out within an appropriate time after the construction of each layer of sidewalls is completed, so as to improve the overall effect of grinding.
