Spodosol wheat straw simple draining tank and method for making

Abstract

The invention relates to a simple lime soil straw spillway which can effectively drain off rain water on roads and roadways and a preparation method thereof. The simple lime soil straw spillway is arranged at a side slope of a road shoulder; a fan-shaped watershed, a lime soil straw groove and a part of the lime soil straw groove that goes through a side ditch deeply are connected with each other in sequence, the aim of effectively draining off water is reached through an opposite slope of the road shoulder and a watershed slope. The invention is applied to draining off water from roads in alluvial plain area of Yellow River which is not provided with vertical curbs, and the invention is characterized by good efficiency of draining off water, simple construction technology and low producing cost and so on.

Description

technical field [0001] The invention relates to a roadbed drainage device and a manufacturing method thereof, in particular to a new roadbed drainage lime soil wheat straw simple drainage channel device and a manufacturing method thereof. Background technique [0002] The road surface water below the secondary road grade is generally discharged by the drainage facilities of the road crown slope, road shoulder and central divider. The road shoulder drainage facilities are composed of mid-surface transverse slope, triangular sump, discharge outlet and rapid flow trough, etc. Ground drainage facilities usually include: side ditch, drainage trough, intercepting ditch, drainage ditch, drop water, rapid flow trough, water barrier, etc. . With the development of highway construction, the importance of pavement drainage is also increasing. In the alluvial plain area of ​​the Yellow River, silt is the main roadbed filling material, but the subgrade slope filled with this silt has p...

AI Technical Summary

Problems solved by technology

[0003] (1) In recent years, with the in-depth implementation of my country's national environmental protection policy and the further implementation of the new concept of "smooth, safe, comfortable, and beautiful" trunk road maintenance, the requirements for landscape along the road have gradually increased. Whether it is in the design or in the use of materials will affect the integrity and continuity of the greening on both sides of the road shoulders, and it is not in harmony with the surrounding environment

[0004] (2) With the extension of the service life, the newly filled subgrade will sink, which will cause the traditional rapid flow tank to break and the bottom of the tank to collapse, causing rainwater to infiltrate, eroding the side slope of the subgrade, and affecting the quality of the subgrade. stability

[0005] (3) The strength of materials used in traditional rapid flow tanks is low, and the ability to resist foundation subsidence is poor. Therefore, the tank body will use a larger size during design and construction, which will inevitably increase the masonry volume, increase costs, and make construction difficult. also increased accordingly
