Manhole cover support for road inspection well, support assembly and road surface construction method

Abstract

The invention relates to the technical field of road construction, and provides a well lid support seat of a road inspection well. The well lid support seat comprises a support seat body and a lifting support seat used for lifting the height of the well lid support seat, wherein the lifting support seat is connected with the support seat body, and well lid support tables which are respectively the first well lid support table and the second well lid support table are respectively arranged on the inner side walls of the support seat body and the lifting support seat. Before the upper layer asphalt concrete pavement of the well lid support seat of the road inspection well, lower layer asphalt concrete around the well lid support seat does not need to be dug away for well lid support seat height increase, and the lower layer asphalt concrete around the road inspection well can survive at one time, so that the integrality of the pavement around the well lid support seat is good, the quality is ensured, and the damage cannot easily occur; in addition, the digging removal and the repair of the lower layer asphalt concrete are avoided, so that the materials and the cost are reduced. Finally, the well lid support seat does not need the height increase, so that three-day to five-day construction period is at least saved, and the urban road fast passing requirements can be particularly met.

Description

technical field [0001] The invention relates to the technical field of urban road construction, in particular to a well cover support for a road inspection well, a support assembly and a road surface construction method. Background technique [0002] Various inspection wells are often found on urban roads. During road construction, for the construction methods of pavement structures including inspection wells, please refer to Figure 1-5 , mainly including the following steps: [0003] S1, fixing the manhole cover support 101 through the temporary fixing layer 102, so that its top surface is flush with the upper surface of the lower asphalt concrete 104 to be laid, thereby facilitating the laying of the lower asphalt concrete 104 of the road; [0004] S2, cover the manhole cover, specifically to buckle the manhole cover on the manhole cover support platform 103, and carry out the laying of the asphalt concrete 104 of the lower layer of the road; [0005] S3. Excavate the ne...

Problems solved by technology

[0008] (1) The lower asphalt concrete 104 around the manhole cover support 101 needs to be laid together with the lower asphalt concrete 104 at other positions on the road, and then the lower asphalt concrete 104 around the manhole cover support 101 is excavated, and then the manhole cover support is filled with asphalt concrete Around 101; thus not only wasting materials, but also excavating the newly paved asphalt concrete will also generate muck and garbage

[0009] (2) There are hidden dangers in the filling method. Regardless of whether small machinery or manual work is used, the compaction and joint quality will not be as good as the first-time survival; Due to the limitation of construction temperature and price, cement concrete is generally used as filling material, which will make it difficult for the filled place to be integrated with the asphalt concrete surface, which will lead to the occurrence of diseases under the frequent dynamic load of vehicles;
