One-way permeable roadbed retaining wall along the river

Abstract

The invention belongs to the technical field of building walls, and particularly relates to a unidirectional water-permeable subgrade river side retaining wall. The unidirectional water-permeable subgrade river side retaining wall comprises a wall body and a base, the wall body comprises a wall face, a wall top and a wall back, the wall back is closely connected with subgrade filling, the wall face faces river water, the wall top is connected with the top face of a subgrade, a unidirectional water-permeable material layer is arranged on the wall back, and comprises a hollow mesh frame, a fiber soil material layer and unidirectional water-permeable geotechnical cloth, and the hollow mesh frame is closely connected with the wall back. According to the unidirectional water-permeable subgrade river side retaining wall, the water subgrade can be protected effectively and well, the unidirectional water-permeable function of the subgrade river side retaining wall is achieved, the aim of controlling the dry and wet states of the subgrade is achieved by controlling in and out of water, and finally water damage of the subgrade river side is effectively reduced.

Description

Technical field [0001] The invention belongs to the technical field of building walls, and specifically relates to a unidirectional permeable retaining wall along a river roadbed. Background technique [0002] Due to the needs of engineering construction, more and more highway projects are constructed along rivers and reservoirs. The highway subgrades built along rivers and reservoirs are both bearing bodies and man-made reservoir banks. Subgrade is the foundation of highway construction, and the quality of subgrade must be reflected in the road surface. The stability of subgrade directly affects the quality of highway use, the difficulty of repair, and the later maintenance of highway. Water is an important factor that endangers the strength and deformation of subgrades. The effects of flooded subgrades on the impact, scrubbing, erosion, softening of subgrade fills and water level rise and fall, etc., will affect the safety of subgrades and easily cause subgrade water damage.

Problems solved by technology

[0003] In order to protect the submerged subgrade well and ensure smooth transportation and safe driving, the existing technology mainly adopts the slope protection at a large angle, and the method of leaving grooves and ditches at the top of the slope section to prevent the wall from collapsing as much as possible without water seepage. This method is complex in process, high in cost, and has no obvious effect
