Anti-settling base with high stability

Abstract

The invention relates to the technical field of road infrastructure, and discloses an anti-settling base with high stability. The anti-settling base comprises a base body with a circular cross section, wherein the inner portion of the base body is provided with a through hole with a circular cross section, the annular outer side wall, close to the top, of the base body is fixedly connected with afixing block with an annular cross section, a plurality of T-shaped sliding grooves are evenly and equidistantly formed in the annular inner side wall of the base body and distributed in an annular matrix, the T-shaped sliding grooves are internally and slidably connected with T-shaped sliding blocks, and the ends, away from openings of the T-shaped sliding grooves, of the T-shaped sliding blockspenetrate through the corresponding openings of the T-shaped sliding grooves, extend to the outside and are jointly fixedly connected with a supporting block with an annular cross section. The anti-settling base with the high stability has the advantages that the force of a manhole cover is decomposed through the T-shaped sliding blocks, the force is consumed through two tension springs and two springs, and the settlement of the manhole cover is prevented under the premise of not affecting the road traffic.

Description

technical field [0001] The invention relates to the technical field of road infrastructure, in particular to an anti-subsidence base with high stability. Background technique [0002] When installing the manhole cover, first dig a large enough well hole on the sewer mouth, then install the manhole cover base in the well groove, then fill a certain amount of asphalt concrete in the well groove, and tamp it layer by layer until the manhole cover base is tight. Install the well cover firmly on the ground, install the manhole cover in the base, and use a road roller to roll the asphalt concrete until it is at the same height as the ground. After the temperature of the asphalt concrete drops to room temperature, the inspection well is installed. The stability of such an inspection well is relatively high. , with the development of urban transportation, the number of vehicles such as buses, private cars, and large engineering vehicles is gradually increasing. These vehicles repeat...
