Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The figure includes comprehensive pipe gallery wall board 1, sealing wall 2, rubber waterstop 3, connection interface 4 between comprehensive pipe gallery wall board and sealing wall, stainless steel plate 5, water-swellable rubber strip 6, and planting reinforcement 7.

[0021] The temporary sealing wall structure of the comprehensive utility gallery is provided with a sealing wall 2, a rubber waterstop 3 and a stainless steel plate 5 for protection. The rubber waterstop 3 is pre-buried in the center of the wall panel at the end of the pipe gallery and forms a circle; the sealing wall 2 is set at a position 300mm away from the end of the pipe gallery, such as figure 1 shown.

[0022] The detailed measures of the construction of the temporary sealing wall are as follows: figure 2 shown. The exposed side of the waterstop is protected by wrapping a protective ...

Abstract

The invention relates to a construction method for a temporary plugging wall for a utility tunnel. The construction method is characterized by comprising the steps that A, a water stop belt in a round is pre-embedded at the tail end of a wall plate of the utility tunnel, one end of the water stop belt extends to the outside of the wall plate of the utility tunnel and is exposed outside, and a protective steel plate is arranged on the outer side of the water stop belt to protect the exposed part of the water stop belt; and B, the plugging wall is arranged at the position with a certain distance from the tail end of the utility tunnel. According to the construction method, under the condition that the utility tunnel is constructed by stages, the tail end of a tunnel body constructed at an earlier stage can be plugged, an interface is reserved for a tunnel body constructed at a later stage, the plugging wall can be disassembled for extension construction without damaging an integral structure, and the waterproof performance at a deformation joint of the earlier-stage tunnel body and the newly-constructed tunnel body can be ensured.

Description

technical field [0001] The present invention relates to the technical field of comprehensive utility corridors, and specifically relates to a new construction method for sealing walls of comprehensive utility corridors that can be adopted when considering the connection between the completed comprehensive utility corridors and the anticipated comprehensive utility corridors . Background technique [0002] The comprehensive pipe gallery is one of the important symbols of the modernization of new urban municipal infrastructure construction in the 21st century. It avoids the trouble of repeated excavation of the road surface due to burying or repairing pipelines. Corrosion prolongs the service life, and it also reserves valuable underground space for planning and development. At the same time, it also actively responds to the construction requirements of "first-class planning, first-class design, first-class construction, and first-class quality". The Ministry of Science and ...
