One-time pouring system for U-shaped bottom plate of cable trench and construction method of one-time pouring system

Abstract

The invention discloses a cable trench U-shaped bottom plate one-time pouring system and a construction method thereof. The system comprises a U-shaped outer mold, a U-shaped reinforcing mesh laid in the U-shaped outer mold, vertical steel wire meshes installed at the junctions of an upper bottom plate and side walls on the two sides of the U-shaped reinforcing mesh, and right-angle inner molds matched at internal corners on the two sides of the U-shaped reinforcing mesh; bottom edges of the right-angle inner molds on the two sides are spaced and connected through a lower rod along the line, top edges of the right-angle inner molds on the two sides are connected through an upper rod along the line, two ends of the lower rod are connected with bottom edges of the right-angle inner molds on the two sides through bolts respectively, and a plurality of bolt holes used for adjusting connection positions are distributed in an end of the lower rod along the line; the upper rod is a telescopic rod, and two ends of the upper rod are downwards clamped on top edges of the right-angle inner molds on the two sides through clamping grooves correspondingly and are downwards pulled and fixed through pull ropes correspondingly to achieve the anti-floating effect. The system is advantaged in that the one-time pouring quality of the U-shaped bottom plate is ensured, harmful flowing of concrete is avoided, and the U-shaped bottom plate pouring device can adapt to U-shaped bottom plates of different sizes.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and in particular relates to a one-time pouring system for a U-shaped bottom plate of a cable trench and a construction method thereof. Background technique [0002] In traditional municipal construction, a large number of power supply systems use underground power supply. In conventional cable trench construction, the safety and impermeability of the structure must be ensured. At the same time, the convenience of construction must also be considered. Therefore, distributed pouring is adopted, and pouring first The U-shaped bottom plate of the cable trench, and then pour the side wall and the top plate; when pouring the U-shaped bottom plate of the cable trench, the bottom plate and the side wall must be poured at 30 cm at one time, so as to ensure the safety of the structure on the weak side and ensure the structure However, due to the certain height difference between the side walls of the ...

[0002] In traditional municipal construction, a large number of power supply systems use underground power supply. In conventional cable trench construction, the safety and impermeability of the structure must be ensured. At the same time, the convenience of construction must also be considered. Therefore, distributed pouring is adopted, and pouring first The U-shaped bottom plate of the cable trench, and then pour the side wall and the top plate; when pouring the U-shaped bottom plate of the cable trench, the bottom plate and the side wall must be poured at 30 cm at one time, so as to ensure the safety of the structure on the weak side and ensure the structure It is impermeable, but because there is a certain height difference between the side wall of the U-shaped bottom slab and the bottom slab, it is very difficult to pour the U-shaped bottom slab at one time, and the normal construction method cannot meet the construction requirements
