Construction structure for constructing road on soft soil foundation

Abstract

The invention relates to a construction structure for constructing a road on a soft soil foundation. The construction structure for constructing the road on the soft soil foundation comprises a crushed-rock layer and a concrete layer which are laid above a soft soil layer in sequence; the construction structure for constructing the road on the soft soil foundation further comprises a plurality oflongitudinal pine piles driven into the soft soil layer; the pine piles are separately lined on the two sides in the length direction of a pavement; the upper ends of the longitudinal pine piles run through the crushed-rock layer and are buried in the concrete layer; and steel reinforcement structures connected with the longitudinal pine piles are buried in the concrete. Through the arrangement, when heavy objects such as pedestrians and vehicles are borne above the concrete layer, the bending resistance of the concrete layer is enhanced through the steel reinforcement structures; and moreover, as the concrete layer and the steel reinforcement structures are connected with the longitudinal pine piles in a supporting and anchoring manner, the crushed-rock layer around a local settlement position bears the pressure load of the concrete layer and the longitudinal pine piles on the two sides bear tensile stress loads on the two sides of the concrete layer when the soft soil foundation under the pavement is locally settled; and therefore, the concrete layer is not easy to collapse or break so that the life and property safeties of the pedestrians on the road are protected.

Description

technical field [0001] The invention relates to the technical field of road structures on soft soil foundations, in particular to a construction structure for building roads on soft soil foundations. Background technique [0002] The definition of soft soil foundation in my country's road industry standards refers to weak soil layers with low strength and high compression, most of which contain certain organic substances. Japan's high-grade highway design code defines it as: mainly composed of loose soil with a large content of fine particles such as clay and silt, organic soil with large pores, peat, and loose sand. Therefore, the soft soil foundation mainly refers to the foundation with high groundwater level, poor stability of fill and structures on it and prone to settlement.

AI Technical Summary

Problems solved by technology

[0003] When the paving process encounters local swampy areas or soft soil areas, if the rigid concrete is laid directly on the soft foundation, there will be a hollow area formed by the settlement of the soft soil foundation under the concrete road, which will easily lead to local collapse of the concrete road situation, which poses a threat to pedestrians and vehicles on the road, therefore, there is room for improvement
