Embodiment Construction
[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0045] refer to Figure 1 to Figure 7 , The present invention provides a pre-embedding method for segment gaskets, which can improve construction efficiency and prevent water seepage, and solve the problem that traditional adhesive gaskets are prone to water seepage. The segment gasket 10 in the present invention is a long rubber gasket, which is arranged along the annular seam and / or the longitudinal seam of the segment 30 to prevent water leakage at the annular seam and / or the longitudinal seam of the segment. exist Figure 7 Among them, the upper surface of the segment 30 is its outer arc surface, and the outer arc surface is the surface close to the soil body after the segment is installed. To simplify the description, "upper" is used hereinafter to refer to the direction close to the outer arc surface of the segment, and "down" is used t...

The invention relates to a pre-embedding method for a duct piece sealing gasket. The pre-embedding method comprises the following steps: providing a duct piece steel mould, forming an embedding groovein the surface of the duct piece steel mould, and providing a through hole in the bottom surface of the embedding groove; providing an adsorption device and the sealing gasket, penetrating the adsorption device in the through hole, and partially placing the sealing gasket in the embedding groove, so that the rest parts of the sealing gasket protrude out of the surface of the duct piece steel mould, and the sealing gasket is attached to the surface, opposite to the adsorption device, of the sealing gasket; applying the adsorption force to the sealing gasket through the adsorption device so that the sealing gasket can be fixed in the embedding groove; enclosing the duct piece steel mould into a casting space of the duct piece, and pouring the concrete in the pouring space, so that the part,protruding out of the surface of the duct piece steel mould, of the sealing gasket is buried in the concrete, after the concrete is solidified, the duct piece steel mould is disassembled, and the sealing gasket is pre-buried in the duct piece. According to the method, the sealing gasket is fixed in a pre-embedding mode, the pasting step is omitted, and the construction efficiency is high.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a pre-embedding method for segment sealing gaskets. Background technique [0002] Generally speaking, the main seepage channel for water seepage at the joint of the segment is through the contact surface of the segment and the gasket. Traditional segment gaskets, such as the Chinese patent CN205078287U, fix the gasket on the segment after the segment is produced by pasting. However, the construction steps of pasting are cumbersome, and the tightness of the pasting is not good, which is prone to water seepage Condition. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a pre-embedding method for segment gaskets, which can solve the problem that the traditional adhesive gaskets are prone to water seepage. [0004] The technical scheme for realizing the above-mentioned purpose is: [0005]...
