Embodiment 1

[0043] Such as figure 1 and Figure 4 As shown, a plastic waterproof board fixing device for the initial lining of the underground excavation of the pipe gallery in this embodiment includes a pre-embedded device 3, a fixed base plate 4 and a plastic waterproof board 5, and one end of the pre-embedded device 3 is welded and fixed On the grid steel arch 2 in the lining 1, a fixed base plate 4 is installed at the other end, and the plastic waterproof plate 5 is pasted and fixed through the fixed base plate 4, and the plastic waterproof plate 5 is fixed on the fixed base plate 4 by pasting. , effectively avoiding false welding, welding penetration and welding infirmity caused by the traditional use of hidden nail rings to weld and fix the waterproof board, ensuring the firmness of the laying and installation of the plastic waterproof board 5, avoiding water seepage in the pipe gallery, and improving the pipe gallery Flashing construction quality and durability of concrete structu...

Embodiment 2

[0049] In this embodiment, a method for laying a plastic waterproof board for the initial lining of a pipe gallery underground excavation uses the fixing device described in Embodiment 1 to lay the waterproof board, which specifically includes the following steps:

[0050] Step 1. Make a fixed substrate 4

[0051] Take the whole roll of waterproof board, cut it into several rectangular fixed substrates 4 with a size of 200mm×50mm, and prepare for construction.

[0052] Step 2. Making the pre-embedded device 3

[0053] Use flat steel to make a hollow box 32, the width and height of the inner hole in the hollow box 32 match the width and thickness of the fixed substrate 4 respectively, to ensure that the rectangular fixed substrate 4 of 200mm×50mm can pass through the hole in the box; then The installation frame 31 is made by processing steel bar scraps on site into the shape of channel steel, ensuring that its processing length is equal to the distance from the initial lining ...

Abstract

The invention discloses a pipe gallery underground excavation primary lining plastic waterproof plate fixing device and a waterproof plate laying method, and belongs to the technical field of buildingconstruction. The pipe gallery underground excavation primary lining plastic waterproof plate fixing device comprises an embedded device, a fixing base plate and a plastic waterproof plate, wherein one end of the embedded device is welded and fixed to a grating steel arch frame in an underground excavation primary lining, the other end of the embedded device is provided with the fixing base plate, and the plastic waterproof plate is pasted and fixed through the fixing base plate. The invention further provides a laying method of the pipe gallery underground excavation primary lining plastic waterproof plate, and the fixing device is adopted for laying the waterproof plate. By the adoption of the technical scheme, the phenomena that in a traditional method, the waterproof plate is missed in welding, penetrated in welding and infirm in welding in the laying process can be effectively avoided, the firmness of installation and fixation of the plastic waterproof plate is guaranteed, and the construction quality of the pipe gallery waterproof plate and the durability of a concrete structure are improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a plastic waterproof board fixing device and a waterproof board laying method for the initial lining of a pipeline tunnel. Background technique [0002] With the continuous progress of society and the rapid development of urban construction, the application of underground comprehensive pipe gallery is becoming more and more common. The depth is deeper, so that a large part of the main structure of the pipe gallery is below the water level. At this time, the waterproof of the pipe gallery is very important. Therefore, in order to ensure the quality of the project, the lining waterproof board must be constructed in time after the completion of the primary lining of the underground excavation of the pipe gallery and before the construction of the second lining. [0003] During the waterproof construction process of the comprehensive pipe gallery, the m...
