Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the construction method of the basement concrete wall perforation and pipe penetration in this specific embodiment includes the following steps:

[0019] (1) Carry out the pipeline perforation construction on the concrete wall 1. On the inner wall of the concrete wall 1, a plurality of screw mounting holes 2 are evenly spaced around the direction of the pipeline perforation centerline. The centerline direction of the screw mounting holes 2 and the pipeline The direction of the center line of the perforation is parallel, and the inner wall of the concrete wall 1 and the position around the pipe perforation are ground and rough, and the rough wall after grinding and the screw mounting hole 2 are cleaned. A mounting screw 3 arranged on the same centerline as the screw mounting hole 2 is implanted in the middle;

[0020] (2) Obtai...

Abstract

The invention discloses a construction method for perforating and pipe penetrating of basement concrete wall. A pipeline penetrating hole is formed in a concrete wall body, a screw rod mounting hole is formed in the inner wall face of the concrete wall body around the pipeline penetrating hole, a mounting screw rod is arranged, a mounting bottom plate is obtained, a pipeline mounting hole is formed in the mounting bottom plate, a mounting bottom plate is bonded to the inner wall face of the concrete wall body, the mounting screw rod penetrates through the mounting bottom plate, an inner ring groove and an outer ring groove are formed in positions, located on the inner side of the mounting bottom plate and located on the inner side and the outer side of the mounting screw rod, of the inner side of the mounting bottom plate respectively, grouting pipes capable of conducting grouting towards the inner ring groove and the outer ring groove respectively are further fixedly arranged on the outer side face of the mounting bottom plate, a perforated pipeline is obtained, the perforated pipeline penetrates through the pipeline penetrating hole, an inner ring waterproof sealing ring and an outer ring waterproof sealing ring which share the same center line are pre-fixedly arranged on the outer side of the mounting bottom plate, a mounting gland is obtained and arranged on the perforated pipeline in a sleeving mode, the mounting screw rod penetrates through the mounting gland and presses the inner ring waterproof sealing ring and the outer ring waterproof sealing ring on the mounting bottom plate through mounting nuts, and the inner ring groove and the outer ring groove are grouted through the grouting pipes.

Description

technical field [0001] The invention relates to the field of pipeline installation, in particular to a construction method for perforating and perforating pipes in a concrete wall of a basement. Background technique [0002] The through-wall pipe is a kind of pipe that is pre-buried or buried in the wall in order for the equipment pipeline to pass through the wall. In the basement environment, one side of the concrete wall is the water-facing surface, and the other side is the back-water surface. In this regard, when piercing the hole for the basement concrete wall, it is necessary to deal with the sealing problem between the piercing tube and the concrete wall. . The conventional construction method is to pre-embed the steel casing during the construction of the concrete wall structure, and then carry out the pipe penetration operation of the main pipe in the steel casing, and set a water-stop seal between the steel casing and the main pipe. circle, in order to achieve th...
