Prefabricated laminated steel concrete two-hole culvert

Abstract

The invention discloses a prefabricated laminated steel concrete two-hole culvert. The prefabricated laminated steel concrete two-hole culvert comprises a bottom plate 1, wall boards 2, cover plates 3, edge strips 4, an inner bottom plate 5, a cushion layer 6, a bottom waterproof plate 7, upper covering waterproof plates 8 and waterproof strips 11, wherein the cushion layer 6 is paved on an excavated foundation; the bottom waterproof plate 7 is spread on the cushion layer 6; the bottom plate 1 is cast on the waterproof plate 7 in situ; lines are placed on the bottom plate 1; the wall boards 2 at two sides and in the middle part are suspended on the bottom plate 1 and are finely adjusted, aligned and leveled; the two cover plates 3 are respectively placed at the top parts of the wall boards 2; the bottom plate 1 is connected with connecting ribs of the wall boards 2, and concretes are filled to form the edge strips 4 and the inner bottom plate 5; and construction gaps among the wall boards 2 and the cover plates 3 are subjected to waterproof gap blockage treatment, the waterproof strips 11 and the covering waterproof plates 8 are paved, the waterproof plates 7 and 8 are welded to form a seal, and soil is filled. The prefabricated laminated steel concrete two-hole culvert is convenient and fast in construction, good in quality, long in durability, waterproof, reliable and the like, and can be used as a culvert, a channel and a municipal integrated pipe ditch below urban roads and high-speed roads.

Description

technical field [0001] The invention relates to a large reinforced concrete culvert, which is suitable for structures such as culverts and municipal comprehensive pipe trenches under highways or urban roads, and is also suitable for large highway passages or culverts with strict waterproof requirements. Background technique [0002] Today's cities occupy more and more land. Under newly built roads or in the renovation of pipe networks, large-scale comprehensive pipe trenches are needed to gather facilities such as flood discharge, sewage discharge, water supply pipelines, power pipelines, gas, municipal lighting, etc. A culvert with a large cross-section is formed, which is easy to use and maintain. With the same cross-sectional area, the cost of double holes is lower than that of single holes while meeting the same requirements, and it is suitable as a central integrated pipe trench. [0003] At present, the construction of drainage culverts and central comprehensive pipe ...

AI Technical Summary

Problems solved by technology

Generally, the main pipe trench is a double-hole frame structure with a span of more than 5 meters, and the total length of the double-hole cover plate reaches more than 12 meters; its on-site construction workload is large, the environment is poor, the progress is slow, and it is three-dimensional construction, which has poor safety; Its construction steps are to dig the foundation pit first, construct the foundation of the box culvert, and then construct the walls and cover plates on both sides of the box culvert. These steps are serial operations, that is, after the previous step is completed and a certain structural strength is reached. Only under certain circumstances can the next step be started, which requires many processes and takes a long time
