[0002] In the construction process of rectangular top pipe channel, the side wall drainage ditch as the key component of drainage system has important role to guarantee the water flow discharge in the channel and improve the structural safety. The traditional construction method usually adopts the processes of first jacking the main pipe section, then drilling, planting the reinforcement, binding the reinforcement and casting the drainage ditch on site. However, this process flow has some technical problems and adverse factors, which need to be improved.
[0003] Firstly, in the traditional process, the installation of the drainage ditch usually cannot be integrated with the top pipe section, which leads to the problem of poor deformation adaptation between the drainage ditch and the main structure. In the operation period, the top pipe channel may have slight intersegment deformation, which leads to the cracks of the drainage ditch, and further affects the drainage function and even the long-term safety of the structure.
[0004] Secondly, the traditional on-site construction needs workers to drill, which not only has the safety hazard of blind drilling, but also may damage the reinforcement structure of the pipe section, and even affect the integrity of the concrete protective layer, which brings risks to the safety of the overall structure. In addition, the dust pollution problem in the drilling operation process, especially in the closed working environment, has adverse effects on the health of workers and the construction site environment.
[0005] Finally, the on-site construction needs a large amount of labor and equipment investment, the construction efficiency is relatively low, the energy consumption is high, and the maintenance and replacement in the later period are difficult, which seriously affects the engineering progress and quality, so the utility model provides a new type side wall drainage ditch structure for rectangular top pipe channel.

[0007] Further, the gutter structure comprises a rubber base body, the gutter is arranged on the side wall close to the main pipe section, the stress release cavity is arranged on the side wall away from the main pipe section, the anti-warping angle is arranged on one side of the stress release cavity, and the anti-warping angle is in contact with the axillary angle.
[0008] Further, the gutter structure is integrally formed by precasting, and the gutter structure is adhered to the axillary angle by a high-performance adhesive.
[0009] Further, the rubber base body is made of high-molecular chloroprene rubber.
[0010] Further, the stress release cavity has a width of 50 mm and a height of 110 mm, and is used for releasing the stress caused by the deformation of the gutter structure of the main pipe section during use.
[0011] Further, the anti-warping angle is an arc-shaped angle, so that the adhesion of the rubber base body and the axillary angle is more stable.
