Formwork for construction joint of pipe gallery wall and construction method

Abstract

The invention discloses a formwork for a construction joint of a pipe gallery wall. The formwork comprises an upper Z-shaped shaping formwork, a lower Z-shaped shaping formwork, steel formwork strips,long tie bar bolts, tapered iron, diagonal brace sleeves, rib plates, a water-stop belt, connecting flanges and connecting bolts; the formwork is characterized in that the water-stop belt 8 is pressed between two formworks by using the upper shaping formwork and the lower shaping formwork in a split manner, thereby guaranteeing that the position of the water-stop belt 8 is fixed and formwork shifting and falling phenomenon is avoided; the formwork is vertically fixed through the steel formwork strips 3 and the long tie bar bolts 4, and the upper shaping formwork and the lower shaping formworkare reinforced through the diagonal brace sleeves 6 and the rib plates 7, so that the formwork cannot deform and incline in the grouting and pouring process. The formwork disclosed by the invention has the advantages of simple structure, strong practicability and high firmness; the water-stop belt is prevented from offsetting or falling and the like, the perpendicularity of the construction jointof the pipe gallery wall is guaranteed, the phenomenon that the construction joint inclines is not likely to happen, the construction quality of the construction joint of the pipe gallery wall is improved, and subsequent construction of a pipe gallery is facilitated.

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...
