Side slope drainage prefabricated bionic component suitable for freezing-thawing deformation and construction method

Abstract

The invention relates to a side slope drainage prefabricated bionic component suitable for freezing-thawing deformation and a construction method thereof. The component comprises multiple U-shaped trough bodies with small fronts and big rears, and the U-shaped trough bodies are mounted in a plug-in mode in sequence. Each U-shaped trough body comprises a base plate and side plates perpendicular tothe two sides of the transverse direction of the base plate, wherein the base plate is an isosceles trapezoidal plate with a narrow front and a wide rear, and the end faces of the transverse two sidesof the base plate are provided with base plate longitudinal protrusions; the side plates are rectangular plates; the positions, corresponding to the longitudinal protrusions of the base plate, of theinner sides of the bottoms of the side plates are provided with side plate longitudinal grooves; the longitudinal protrusions of the base plate are inserted into the side plate longitudinal grooves to enable the base plate and the side plates to form the U-shaped trough body with the small front and the big rear. The joint of the side slope drainage prefabricated bionic component suitable for freezing-thawing deformation is similar to an animal joint. When the base plates ascend or descend under the action of frost heaving and thaw settlement, connecting parts can rotate to deform without squeeze damage and can adapt to freezing and thawing cycle repeated deformation. Moreover, the structure stability and the drainage function of the side slope drainage prefabricated bionic component aremaintained. The problems that rigid drainage ditches in permafrost regions and seasonally frozen soil regions can hardly adapt to freezing-thawing deformation and are destroyed easily can be solved.

Description

technical field [0001] The invention relates to a drainage ditch, in particular to a prefabricated bionic component for slope drainage adaptable to freeze-thaw deformation and a construction method thereof. Background technique [0002] Frozen soil (including permafrost and seasonal frozen soil) is widely distributed around the world. Frost heave will occur when the slope freezes in the permafrost area, and the slope surface will undergo slight uplift and deformation. In the warm season, the ice will melt and subside. Frost heave force is generally dozens of times greater than the self-heavy structure of the drainage structure, which makes the current rigid drainage structure easily dislocation, fracture and damage under the action of frost heave force, and loses drainage effect. This problem is particularly serious in permafrost regions. Conventional rigid drainage ditches cannot resist frost heave deformation, and are basically completely destroyed under the action of a fr...

Problems solved by technology

[0002] Frozen soil (including permafrost and seasonal frozen soil) is widely distributed around the world. Frost heave will occur when the slope freezes in the permafrost area, and the slope surface will undergo slight uplift and deformation. In the warm season, the ice will melt and subside. Frost heave force is generally dozens of times larger than the self-heavy structure of the drainage structure, which makes the current rigid drainage structure easy to be dislocated, broken and damaged under the action of frost heave force, and loses drainage effect

This problem is particularly serious in permafrost regions. Conventional rigid drainage ditches cannot resist frost heave deformation, and are basically completely destroyed under the action of a freeze-thaw cycle. In order to solve this problem, dry rubble drainage ditches are currently used in the area , the dry rubble drainage ditch has a good effect on adapting to frost heave deformation, but there are many gaps, it is easy to leak water, and the drainage effect is poor. Because it is constructed by dry masonry method, it can only be used in the gentle area of ​​the ground surface, and cannot be used as a slope. drainage measures

[0003] At present, the Sichuan-Tibet Expressway, Qinghai-Tibet Expressway, and Sichuan-Tibet Railway are all in the survey and design stage, especially the Qinghai-Tibet Expressway. Most of the road sections are in the permafrost area, and there is an urgent need for suitable slope drainage engineering measures. Based on this, it is necessary to develop a set that can adapt to the plateau. An anoxic and high-cold working environment, and a drainage structure that can adapt to frost heaving and thawing cycle deformation
