Embodiment Construction

[0032] Attached to the following Figure 1-4 This application will be described in further detail.

[0033] The embodiments of the present application disclose an underground protective wall for municipal engineering.

[0034] refer to figure 1 , an underground protective wall for municipal engineering, comprising a top plate 1, two sides of the top plate 1 are provided with support plates 2, the two support plates 2 are respectively fixed on both sides of the underground passage, and the opposite surfaces of the support plate 2 are fixed with support plates Block 30, the upper surface of the support block 30 abuts on the bottom surface of the top plate 1, the support block 30 strengthens the bearing capacity of the top plate 1, so that the top plate 1 is supported more stably.

[0035] refer to figure 1On the upper surface of the outer wall of the top plate 1, a number of abutting blocks 29 are fixed evenly spaced. The upper surface of the abutting blocks 29 is arc-shaped,...

Abstract

This application involves an underground protective wall for municipal engineering, including the top board, with a supporting board on both sides of the top board.The card connector fixed between the two support plates includes the round board rotating on the bottom of the top plate, two arc shaped rods on the bottom of the round board, and fixed on the arc lever away from the end of the round board.The plug -in rod, the bottom surface of the top plate is opened with a installation slot, which is connected to the inner cavity of the installation slot on the surface of the installation slot.The one -end of the inserting rod far from the side of the arc rod passes through the side wall of the top plate and is inserted on the support plate. The installation of the installation slot is set to drive several driving parts that drive several round board synchronous rotation.This application has the effect of strong pressure to ensure the health of employees.

Description

technical field [0001] The present application relates to the technical field of municipal construction, in particular to an underground protective wall for municipal engineering. Background technique [0002] At present, construction workers usually only wear labor insurance and do not take other safety protection measures when constructing underground tunnels. [0003] The existing application publication number is the utility model patent of CN206052774U. The open movable wall panel has a fixed part on the top outer side of the bottom wall panel, and a shaft sleeve on the bottom outer side of the fixed part. The rotating shaft mutually rotates with the shaft sleeve, and the inside of the movable wall panel has a positioning structure for fixing with the fixing part and the bottom wall panel. [0004] In view of the above-mentioned related technologies, the inventor believes that the protective wall has only one positioning structure connected to the inner wall of the un...
