Description

Technical Field

[0001] The present application relates to the field of geotechnical engineering technology, and in particular to a lateral support and reinforcement device for a road cutting ditch. Background Art

[0002] Cutting ditches are usually set between the earth shoulder and the debris platform of the excavated roadbed, mainly used to collect road surface water and excavated slope water. Cutting ditches generally adopt rectangular, trapezoidal, U-shaped or triangular cross-section forms. Rectangular cutting ditches are more commonly used in actual projects because they occupy less space and are easy to construct.

[0003] However, because the walls of rectangular side ditches are upright and suspended, the walls of the side ditches of the road cuts are prone to tilt or collapse when the debris platform is slightly deformed, resulting in the ditch water being blocked and seeping into the roadbed, causing the road surface to sink or the roadbed to become soft, and the roadbed strength, water stability and durability are greatly reduced. In order to prevent the side ditches of the road cuts from tipping over, the existing technology adopts the method of setting reinforced concrete transverse support beams at intervals along the longitudinal direction of the side ditches for support and reinforcement. It has the disadvantages of complicated construction process and long construction period, which seriously affects the rescue and traffic maintenance work of the side ditches of the highway roadbed. Therefore, it is very necessary to improve and optimize the support and reinforcement structure adopted in the existing technology. Utility Model Content
