Rain water tank culvert penetration underground pipeline protection device

Abstract

The invention discloses a rain water tank culvert penetration underground pipeline protection device. The rain water tank culvert penetration underground pipeline protection device structurally comprises a water isolation wall, a rainwater inlet, a pile slope, cap stone, a rain water tank culvert body, a sand-gravel cushion, a wing wall, a deformation seam and a pipeline protection device. The rain water tank culvert penetration underground pipeline protection device is structurally provided with the pipeline protection device, when an underground pipeline needs to be paved, a user rotates a fixing bolt to achieve extraction from a fixing hole and a locking hole, a device top cover is pushed to drive a direct gear to be lifted up, a stretchable spring and a limiting block are arranged so that swing of the underground pipeline can be reduced when vehicles pass through the underground pipeline, and pipelines with different sizes can be fixed and borne conveniently; and after paving is completed, the device top cover is closed to insert the fixing hole into the fixing hole, the fixing bolt is used for locking to complete fixation, the overall device is convenient, quick and effectiveto use, the defect that a rain water tank culvert cannot protect the underground pipeline in the proper art is overcome, the pipe fixing effect can be achieved, pipe excursion is not prone to being caused, and practicability is high.

Description

technical field [0001] The invention relates to a protection device for rainwater box culverts passing through underground pipelines, and belongs to the technical field of building construction. Background technique [0002] The rainwater box culvert refers to a culvert built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. When the span is less than 4m, box culverts are used. For pipe culverts, reinforced concrete box culverts are An inexpensive alternative, the piers, upper and lower slabs are all poured in unison. [0003] The prior art discloses the application number: CN201720764288.9 for one-time pouring of underground box culvert vertical pole type box culvert support embedded parts, including box culvert support embedded parts, box culvert support embedded parts are composed of insert rods, U-shaped Support, s...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a protection device for rainwater culverts passing through underground pipelines to solve the problem that rainwater culverts do not have equipment to protect underground pipelines, and cannot prevent the joints on the surface of pipelines from being damaged, which may easily lead to A certain section of the pipeline is offset, and the practicability is poor
