Formwork and construction method for construction joints of pipe gallery wall

Abstract

A formwork for construction joints of a pipe gallery wall, including an upper Z-shaped formwork, a lower Z-shaped formwork, steel mold strips, long tension bolts, oblique irons, oblique tension sleeves, reinforcement plates, and waterstops , connecting flanges and connecting bolts, which are characterized in that the waterstop 8 is pressed between the two templates by using the split upper and lower formwork, so as to ensure that the position of the waterstop 8 is fixed, and the phenomenon that the mold does not fall off occurs. The strips 3 and the long tie bolts 4 fix the formwork up and down, and the upper and lower formworks are reinforced by the cable tie sleeves 6 and ribs 7, so that the formwork does not deform or tilt during the grouting process. The beneficial effects of the present invention are as follows: The structure is simple, the applicability is strong, and the firmness is high. It prevents the waterstop from shifting or falling off, and ensures the verticality of the construction joints of the pipe gallery wall. The construction quality of joints is beneficial to the subsequent construction of the pipe gallery.

Description

technical field [0001] The invention relates to the field of building foundations, in particular to a formwork for construction joints of a pipe gallery wall and a construction method. Background technique [0002] The comprehensive pipe corridor is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] In the construction of an underground comprehensive pipe gallery in a city, the wall thickness is 450mm, and the construction joint of the wall adopts a 400mm mid-buried rubber waterstop. During the construction process, due to the influence of the mid-burie...

Problems solved by technology

[0005] The invention provides a formwork for the construction joint of the wall of the pipe gallery and a construction method. In order to solve a series of technical problems caused by the construction of the wall of the traditional pipe gallery, the present invention is a formwork for the construction joint of the wall of the pipe gallery , using the upper and lower split structure "Z" shaped formwork, the Z-shaped shaped formwork is connected more tightly and firmly by lengthening the tension bolts and oblique tension bolts, adding steel molds at the end to clamp the middle rubber waterstop to ensure the water stop The position of the water belt, the purpose of the present invention is to provide a formwork for the construction joints of the pipe gallery wall-shaped steel formwork, which is mainly used for the construction of the vertical construction joints of the pipe gallery, and improves the construction quality of the construction joints. In order to ensure the construction of the construction joints. Improve the construction quality and ensure the formwork support system is stable and firm
