AI Technical Summary
During the traditional prefabrication of pipe sheets, the installation of rubber seal strips requires manual operation by workers, which is very labor-intensive, time-consuming and costly.
An anchor seal strip is designed, which is installed in the installation groove of the mold by combining the upper part, the protruding part and the lower part of the seal. After the concrete is poured, the seal strip is embedded around the pipe piece.
The anchor seal strip is installed in the prefabricated production process of pipe sheets. After concrete is cured, the seal strip is embedded around the pipe sheet, which significantly saves the installation time before assembling the pipe sheets, improving efficiency, ensuring the shield progress, and saving costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tunnel concrete segment prefabrication, in particular to an anchoring type sealing strip. Background Art
[0002] With the acceleration of my country's urbanization process, urban subway construction has developed rapidly. During the prefabrication process of the segments, the finished segments need to be sent to the shield site for installation after curing. The traditional installation method requires workers to manually install rubber sealing strips on the cured finished segments at the shield site, and then assemble them down the shaft. The installation of a large number of rubber sealing strips is not only labor-intensive, time-consuming and labor-intensive, but also costly. For this reason, an anchored sealing strip is proposed. Utility Model Content
[0003] The utility model aims to provide an anchoring sealing strip, aiming to solve the problems raised in the above background technology.
[0004] The utility model is implemented as follows: an anchored sealing strip comprises a sealing strip, wherein the sealing strip is composed of a sealing upper portion, a raised portion and a sealing lower portion; the sealing strip is installed in a first installation groove and a second installation groove, wherein the first installation groove is provided on a mold side plate, and the second installation groove is provided on a mold end plate, and a base is provided at the bottom of the mold side plate and the mold end plate.
[0005] Furthermore, the dimensions of the first installation groove and the second installation groove are both compatible with the upper portion of the seal.
[0006] Furthermore, the raised portion and the sealing lower portion are both embedded in the pipe segment.
[0007] Furthermore, the mold side panels are provided with two pieces, and the mold side panels are installed on the base.
[0008] Furthermore, the mold end plates are provided with two pieces, and the mold end plates are installed on the base, and the two mold end plates and the two mold side plates form the mold.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The anchored sealing strip is installed on the inner side of the mold cavity during the prefabrication production of the pipe segments. The finished product is obtained after demoulding after concrete pouring. The sealing strip is embedded on the outer side of the pipe segments, which greatly saves the installation time before the pipe segments are assembled into the well, improves efficiency, ensures the progress of the shield, and saves costs to a certain extent.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0016] like Figure 1 and Figure 2 As shown, an anchored sealing strip provided by an embodiment of the utility model includes a sealing strip 3, wherein the sealing strip 3 is composed of a sealing upper portion 31, a raised portion 33 and a sealing lower portion 32; the sealing strip 3 is installed in a mounting groove 1 and a mounting groove 2, wherein the mounting groove 1 is provided on a mold side plate 1, and the mounting groove 2 is provided on a mold end plate 2, and a base is provided at the bottom of the mold side plate 1 and the mold end plate 2.
[0017] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, the sizes of the installation groove 1 and the installation groove 2 are both adapted to the sealing upper part 31, which is conducive to the correct installation and positioning of the sealing strip 3. The protrusion 33 and the sealing lower part 32 are both embedded in the pipe segment.
[0018] like Figure 1 As shown, as a preferred embodiment of the utility model, the mold side panels 1 are provided with two pieces, and the mold side panels 1 are installed on a base.
[0019] like Figure 1 As shown, as a preferred embodiment of the utility model, the mold end plates 2 are provided with two pieces, the mold end plates 2 are installed on the base, and the two mold end plates 2 form a mold with the two mold side plates 1. The setting of this mold is conducive to the fixing of the sealing strip 3 and the subsequent concrete pouring process.
[0020] In the embodiment of the present utility model, the specific process is as follows:
[0021] Step 1: Open the mold and clean it;
[0022] Step 2, close the mold and install the embedded parts and anchor sealing strip 3;
[0023] Step 3, pouring concrete, and waiting for the concrete to solidify to form a pipe segment, at which time the sealing strip 3 is embedded on the outer side of the pipe segment;
[0024] Step 4: De-mould the finished product after steaming and curing.
[0025] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
