[0027] The present application is further explained by the following specific examples, which should not be construed as limiting the scope of the application. Other advantages and benefits of the present application will be readily appreciated by those skilled in the art in view of the disclosure.

[0028] The application will be further described by reference to the drawings, wherein: Figs. 1-2 The application will be further described by reference to the drawings, wherein:

[0029] The present application discloses a kind of wall group pipe construction method. Referring to Figs. 1-2 A kind of wall group pipe construction method, including fixed in wall steel bar wall group pipe 1 and sleeve pipe 2, using the following construction steps:

[0030] Step one, according to design, wall group pipe 1 is placed in the specified wall steel bar position, and is welded with reinforcement to prevent loosening, the spacing between each pipe in wall group pipe 1 is same, so that concrete can be wrapped each pipe when pouring concrete.

[0031] Step two, wall group pipe 1 both ends are blocked using plastic cloth or other materials, prevent subsequent concrete pouring into pipe, by using plastic cloth or other materials to block both ends of wall group pipe 1, it can avoid concrete immersion in wall group pipe 1 when pouring concrete, avoid wall group pipe 1 being blocked by concrete.

[0032] Step three, wall group pipe 1 is positioned and the wall body both ends part is covered with sleeve pipe 2, the sleeve pipe 2 can be plastic pipe in the embodiment, can also be steel pipe, wherein the inner diameter of sleeve pipe 2 is slightly larger than the diameter of wall group pipe 1, the outer side of sleeve pipe 2 is wrapped with plastic film, so that subsequent concrete can be removed, can also be used according to circumstances without removing, in turn assemble and wrap all wall group pipes.

[0033] Step four, wall group pipe 1 is set up wall body formwork 3, formwork 3 includes support formwork 31 and fixing piece 32 for fixing support formwork 31, support formwork is arranged at both ends of wall group pipe 1 for pouring wall concrete, fixing piece 32 is a tensioning screw, formwork 3 is wrapped around both ends of wall group pipe 1 and abuts tightly with both ends of wall group pipe 1, formwork 3 is fixed at both ends of wall group pipe 1 by tensioning screw.

[0034] Meanwhile, the support template 31 comprises a fixed template 311 abutting against the end of the through-wall group pipe 1 and a pouring template 312 arranged at both ends of the fixed template 311, and the support template 31 is fixed by passing a pull screw through the two fixed templates 311. In order to avoid the concrete from being poured into the joint between the fixed template 311 and the sleeve pipe 2 during the pouring of the concrete, a sealing ring is arranged at the end of the sleeve pipe 2 and abuts against the fixed template 311. The sealing ring can well play the role of sealing and preventing leakage, and further plays the role of sealing the through-wall group pipe 1.

[0035] The pouring template 312 comprises two vertical standing plates arranged at the side of the through-wall group pipe 1 and the side of the wall respectively, and the two standing plates are perpendicular to each other. The standing plate arranged at the side of the through-wall group pipe 1 is arranged perpendicularly to the fixed template 311. In order to wrap each pipe in the through-wall group pipe 1 with the concrete, the interval between the standing plate arranged at the side of the through-wall group pipe 1 and the through-wall group pipe 1 is arranged.

[0036] In order to increase the overall strength of the support template 31, a plurality of reinforcing rods 33 are arranged on the outer wall of the support template 31 in a longitudinal and transverse interlaced manner, and the reinforcing rods 33 are fixed on the support template 31, which can further increase the overall strength of the support template 31.

[0037] In order to avoid the leakage of the concrete at the joint between the fixed template 311 and the pouring template 312, sponge rubber strips are arranged at the joint between the fixed template 311 and the pouring template 312 to prevent the leakage of the concrete, so that the forming effect is better.

[0038] Step five, pouring the concrete of the wall and vibrating and compacting.

[0039] Step six, after the concrete reaches the condition of the side template disassembly, the template 3 can be disassembled, and then the excess poured concrete is disassembled according to the needs. The inner wall of the underground garage through-wall group pipe 1 often needs to be decorated and has a small length, and it is suggested to be disassembled. The outer wall part can be disassembled or not disassembled according to the position needs. The disassembly points are as follows: first, the excess concrete is cut to the outside of the sleeve pipe by closely abutting against the wall, and then the concrete is chiseled by using the air pipe. It is necessary to control the chiseling force. Since the sleeve pipe 2 is wrapped with a plastic film, the excess concrete has no steel bar, and the concrete strength is insufficient, and the like, the chiseling is relatively easy. After the end is cut and chiseled, the concrete block can be pulled outwards as a whole to achieve the effect of disassembling the excess concrete as a whole. If there is leakage, the excess concrete cannot be chiseled as a whole, and the excess concrete is chiseled from the far end to the near end step by step. After the chiseling is completed, the wall is appropriately polished. After the chiseling is completed, waterproof construction can be carried out. The excess concrete which does not need to be chiseled can be used as a waterproof reinforcing layer, and the unchiseled excess part will be covered by the backfilling soil of the side wall, which has no influence on the appearance and quality.

[0040] Finally, it is to be explained that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
