Isolation waterproof filling structure for highway foundation surface treatment and filling method thereof

Abstract

The invention relates to an isolation waterproof filling structure for road foundation surface treatment and a filling method thereof, and belongs to the technical field of road construction. The isolation waterproof filling structure comprises waterproof cloth laid on the foundation surface, a lime soil layer laid on the waterproof cloth and a cement soil layer laid on the lime soil layer; a plurality of transverse rods and a plurality of longitudinal rods are embedded in the lime soil layer, the transverse rods and the longitudinal rods are distributed in a staggered mode to form grids in the lime soil layer, and a connecting part is arranged between every two adjacent staggered transverse rods and longitudinal rods and enables the transverse rods and the longitudinal rods to be connected together. The waterproof cloth can play a role in preventing water from entering the roadbed. The lime soil layer is high in integrity after being hardened and formed, the transverse rods and the longitudinal rods increase the bearing capacity of the lime soil layer, and under the cooperation of the cement soil layer, it is guaranteed that the roadbed can reach the compactness required by design, and the construction quality of a road is improved.

Description

technical field [0001] The present application relates to the field of road construction, in particular to an isolated waterproof filling structure for road foundation surface treatment and a filling method thereof. Background technique [0002] In the process of highway construction, the treatment of the foundation surface of the highway construction determines the overall quality of the highway. At present, in the construction of the silt foundation, a layer of gravel clay will be filled before filling the roadbed on the silt foundation to ensure The subgrade can achieve the degree of compaction required by the design. However, when the groundwater level is high, due to the water permeability of the base formed by gravel and clay, it is easy for groundwater to seep into the roadbed, which cannot play a waterproof role. Although the tarpaulin can play a waterproof effect, it cannot ensure that the subgrade can meet the design requirements of compactness and reduce the cons...
