Embodiment Construction

[0032] The following is attached Figure 1-4 The application is described in further detail.

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

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

[0035] refer to figure 1A plurality of abutment blocks 29 are evenly spaced on the upper surface of the outer wall of the top plate 1. The upper surface of the abutment block 29 is arc-shaped, and the abut...

Abstract

The invention relates to an underground protective wall for municipal engineering. The underground protective wall comprises a top plate, wherein supporting plates are arranged on the two sides of thetop plate, and a plurality of clamping pieces used for fixing the top plate between the two supporting plates are uniformly arranged on the bottom surface of the top plate at intervals in the lengthdirection of the top plate; each clamping piece comprises a circular plate rotating on the bottom surface of the top plate, two arc-shaped rods rotating on the bottom surface of the circular plate andinserting rods fixed to the ends, away from the circular plate, of the arc-shaped rods; a mounting groove is formed in the bottom surface of the top plate, the circular plates are rotationally connected to the upper surface of an inner cavity of the mounting groove, and the two arc-shaped rods are arranged in a central symmetry mode in the axial direction of the circular plates; and the ends, away from the arc-shaped rods, of the inserting rods penetrate through the side wall of the top plate and are inserted into the supporting plates, and a driving piece used for driving a plurality of circular plates to rotate synchronously is arranged in the mounting groove. The underground protective wall has the effects that the pressure bearing capacity is high, and the life health of staff is guaranteed.

Description

technical field [0001] The application relates to the technical field of municipal construction, in particular to an underground protection wall for municipal engineering. Background technique [0002] At present, when constructing underground tunnels, construction personnel often only wear labor insurance and do not take other safety protection measures. However, gravel often falls in underground tunnels, which brings danger to construction personnel. [0003] The existing application publication number is the utility model patent of CN206052774U, and its technical scheme includes: the protective plate installed on the inner wall of the underground passage, and each protective plate is arranged side by side to form a protective wall. The open movable wallboard has a fixed part on the top outer surface of the bottom wallboard, and a shaft sleeve is provided on the bottom outer surface of the fixed part. The rotating shaft that rotates with the shaft sleeve has a positioning...
