Description

Technical Field

[0001] This utility model relates to the field of water diversion tunnel construction technology, specifically a protective rubber plate for water diversion tunnel construction. Background Technology

[0012] As a preferred embodiment of this utility model, the joint of the overlapping structure is covered with a waterproof membrane.

[0013] As a preferred embodiment of this utility model, support blocks are symmetrically arranged on both sides of the upper surface of the rubber sheet body, and arc-shaped holes are provided on the support blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the protective rubber plate for the construction of the water diversion tunnel is reasonably designed and ingeniously conceived. By laying the main body of the rubber plate at the bottom of the water diversion tunnel, the concrete layer is protected and prevented from being damaged. At the same time, it is convenient to support the trestle bridge at the upper end of the main body of the rubber plate, which facilitates the fixation of the trestle bridge and greatly improves the convenience of use.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a protective rubber sheet for the construction of a water diversion tunnel, including a rubber sheet body 1, the upper end of which is a flat surface, and the lower end of which is an arc-shaped structure adapted to the arc-shaped bottom concrete layer of the water diversion tunnel, which can completely cover and fit the surface of the arc-shaped bottom concrete layer of the water diversion tunnel, and protect the concrete layer at the bottom of the water diversion tunnel.

[0023] Multiple bolt holes 2 are provided on the upper surface of the rubber sheet body 1. The number and position of the bolt holes 2 correspond to the position of the trestle support. Bolts are threaded through the trestle support and connected to the bolt holes 2 to fix the trestle to the rubber sheet body 1, which facilitates the fixation of the trestle.
