Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention is described further as follows:

[0031] The construction method of the pipe gallery waterstop includes the following steps:

[0032] 1), make the waterstop positioning part, the waterstop positioning part includes the outer template 2 and the inner template 3; one section of the outer template 2 is the outer installation part 21, and the other section is the outer extension part 22; the inner template 3. One section is the inner installation part 31, and the other section is the inner extension part 32;

[0033] 2), the inner mold 4 and the outer mold 5 are supported in place;

[0034] 3), install the waterstop 1:

[0035] 3.1), install the inner formwork 3 on the inner end of the inner formwork 4 along the longitudinal direction of the pipe gallery, and connect the inner installation part 31 of the inner formwork 3 with the inner formwork 4 with bolts, and the inner extension part 3...

Abstract

The invention relates to a construction method of a pipe gallery water-stopping belt, belongs to the field of pipe gallery construction, and aims to guarantee the mounting position accuracy of the water-stopping belt and lower the damage rate during the mounting of the water-stopping belt. The method includes: mounting inner formwork at an inner mold; arranging the water-stopping belt in position; mounting outer formwork at an outer mold, wherein the outer formwork is located on the outer side of the water-stopping belt, and the outer formwork and the inner formwork oppositely clamp the water-stopping belt; connecting the outer formwork and the inner formwork. The construction method has the advantages that the inner formwork is mounted before the water-stopping belt is arranged in position, the water-stopping belt can be supported, and the water-stopping belt can be arranged in position conveniently; an identification effect is achieved, and centering of the water-stopping belt and a construction joint is benefited; by an inner mounting part, an outer mounting part, the connection of the corresponding inner mold and outer mold and the connection of the outer formwork and the inner formwork, the butt joint seam, close to one side of a pre-pouring cavity, of the outer formwork and the inner formwork gradually decreases under concrete push force, and the water-stopping belt can be tightly clamped; the water-stopping belt is supported from two sides, and the drooping degree of the water-stopping belt is reduced.

Description

technical field [0001] The invention belongs to the field of pipe gallery construction, in particular to a construction method of a pipe gallery water stop. Background technique [0002] Buried waterstops are usually used for waterproofing at the construction joints of the pipe gallery construction. The mid-buried waterstop is usually fixed by positioning clips and wooden formwork. For example, the application number is CN201710256790.3, and the patent application for the waterproof structure system and construction method of the expansion joint of the underground pipe gallery discloses an underground The installation method of the buried waterstop in the pipe gallery, after the steel bars are bound, put in the buried waterstop, and clamp the buried waterstop with two flat steel bars, and the flat steel is clamped by the steel bars; Then set the wooden formwork, and clamp the buried waterstop through the wooden formwork; finally, carry out pouring, and slowly pull out the f...
