Construction method for synchronous construction of filling wall masonry and electrical line pipe pre-embedding

Abstract

The invention discloses a construction method for synchronous construction of filling wall masonry and electrical line pipe pre-embedding. The construction method comprises the steps: S1, a prefabricated building block mould is manufactured; S2, a pipe distributing concrete building block is prefabricated; S3, a wall body is subjected to line-snapping positioning; S4, a vertical line pipe is erected; S5, filling wall masonry is conducted, specifically, filling wall masonry should be synchronously constructed with line pipe pre-embedding in a masonry body, the pre-embedded line pipe is nested with the prefabricated pipe distributing concrete building block, and then a line box mounting hole is reserved in the wall masonry process; S6, a line box is stabilized; S7, before filling wall plastering, pipe scavenging needs to be conducted, a pipeline is corrected when problems occur, and after pipeline smoothness is confirmed through pipe scavenging, a strip line is threaded; and S8, qualityacceptance is conducted. The construction process is simplified, the work efficiency is improved, the workload is reduced, the overall construction period is shortened, the large number of labor costand material input are saved, and the construction method has good promotion value for omitting wall body line pipe chiseling, ensuring the structure and electrical mounting project quality, and promoting energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the technical field of filling wall masonry for secondary structures of general industrial and civil buildings and electrical concealed pipe wiring engineering, and specifically relates to a construction method for synchronous construction of filling wall masonry and electrical pre-embedded pipes. Background technique [0002] In the cast-in-place frame and frame-shear wall structures of various industrial and civil buildings, electrical conduits are generally reserved and pre-embedded in the cast-in-place beam-slab concrete and secondary structural masonry, throughout the entire process of civil construction. Conventional secondary structures generally use sintered hollow bricks, autoclaved aerated concrete blocks, lightweight aggregate concrete small hollow blocks, etc. to fill wall masonry. Currently, two construction methods are usually adopted for the laying of pre-embedded pipes in filled wall masonry , one is to adopt th...

Problems solved by technology

[0005] 2. The operation process is complicated, which increases the workload of groove repair and the material consumption of groove repair concrete. The labor intensity of workers is high, the work efficiency is low, and labor costs, machinery costs, material costs and management costs are high.

[0006] 3. The vertical and horizontal grooves of the wall reduce the load-bearing section of the structure, resulting in excessive eccentricity, damage to the strength of the masonry itself, affect the bearing capacity of the masonry, and affect the integrity and beauty of the wall; the concrete for filling the grooves is mostly mixed on site, and the strength cannot be achieved. To ensure that the requirements are met, the safety of the wall structure is reduced, and there are certain quality hidden dangers

[0007] 4. Plastering hollows and cracks are very easy to appear on the grooved part of the wall, causing cracks on the wall surface, and it is difficult to repair in the later stage, and it is difficult to effectively deal with it, which seriously affects the normal work and life of users

[0008] 5. The construction energy consumption is large, the power consumption of the slotting machine tools and the water consumption on the site are large, the energy consumption is significant but the utilization rate is low, and a large amount of construction waste, waste water, dust, noise and other environmental pollution are generated during the slotting process, which is harmful to the ecology The environment poses a hazard, which is not conducive to the realization of the four sections and one environmental protection (energy saving, land saving, water saving, material saving and environmental protection)

[0009] 6. The wall plastering construction can only be carried out after the concrete for filling the groove reaches a certain strength, which takes up the overall construction period of the secondary structure and has an adverse effect on the project progress management

Although this method can avoid the quality problems caused by wall grooving, it is necessary to arrange special personnel on site to carry out the block grooving operation according to the actual required size. The hazards of environmental pollution such as construction waste, waste water, dust, and noise cannot be solved. At the same time, due to the low strength of the filled wall blocks themselves, the blocks are easily broken and damaged during the groove cutting process, resulting in waste of materials. If broken bricks are used to protect the wall masonry, there are more hidden dangers to the safety and stability of the masonry structure

Most masonry teams do not have the ability to install pipes, and the close cooperation between the masonry team and the hydropower team is required, which increases the difficulty of on-site management, easily leads to unclear division of responsibilities, and mutual blame when problems arise, which is not conducive to the safety, quality and progress of the overall project manage
