Abstract

The invention provides a water stop belt pipe for joint seal of an underground continuous wall, and a use method thereof. The water stop belt pipe includes a tubular flexible housing; the housing has an opening extending in the axial direction, and the opening is sealed by a sealing strip; a steel wire rope extending in the axial direction of the housing is positioned on each of an inner side and an outer side of the sealing strip; the length of the steel wire ropes is longer than the length of the housing, and two ends of the steel wire ropes are exposed outside; a water stop belt is limited in the housing, a tail end of the water stop belt is stuck to an inner wall of the housing, the center of the water stop belt includes two separation layers, and the two separation layers are separated from each other in the housing; a front end of the water stop belt is limited in the opening; and injection pipes are limited in the housing. The water stop belt is easy to transport, can be cut for use according to a desired length, is easy to install and position, facilitates construction, will not be damaged during pouring of the continuous wall, and can achieve an excellent water-stop seepage-proofing effect for the continuous wall.

Description

technical field

[0001] The invention relates to the technical field of underground diaphragm wall joint water stop, in particular to a water stop pipe used for underground diaphragm wall joint water stop. Background technique

[0002] With the rapid development of my country's construction industry, the scale and depth of underground space development are gradually increasing. Due to its strong applicability, small construction influence range, and high rigidity of the wall, the underground diaphragm wall is more and more used in deep, The enclosure structure system of a large foundation pit, at the same time, because it often overlaps with the basement exterior wall, the underground diaphragm wall can also be used as the enclosure structure and the basement exterior wall (two walls in one), saving a lot of energy compared with other enclosure measures The investment has broad development prospects.

[0003] The underground continuous wall is to excavate a trench with a certa...
