Well lid reinforcing structure anchored with existing pavement foundation through joint bars and method

Abstract

The invention provides a road foundation engineering construction technology, and particularly relates to a well lid reinforcing structure anchored with an existing pavement foundation through joint bars and a method. The well lid reinforcing structure is arranged at a wellhead of a sewer and is used for reinforcing a well lid support of an existing pavement; and the well lid reinforcing structurecomprises the well lid support, an annular cutting groove, well lid ring bars, a support cushion formwork, the joint bars and concrete. The well lid support is supported through concrete pouring, thestability of the reinforced well lid support can be effectively improved due to the fact that the pressure resistance of the concrete is high, a road is smooth and attractive, the smoothness and driving comfort of an existing road surface are guaranteed, and the traffic safety and service level of an urban road are improved. Meanwhile, the maintenance rate for quality defects caused by the quality problem of a well lid in the later period is reduced, the maintenance cost in the later period is saved, the influence of the road construction closing period on the surrounding social environment is reduced, the influence of maintenance waste on the surrounding environment is reduced, and good economic and social benefits are achieved.

Description

Technical field[0001]The present invention belongs to the construction technology of road infrastructure, and in particular, the present invention relates to a well cover reinforcement structure and method for utilizing junvenation and existing pavement base anchors.Background technique[0002]At present, most urban roads in my country have used lime stabilizers, lime powder coal ash stabilizers, lime powder coal ash stabilized stone and cement stabilized gravel as a base structure, asphalt concrete as a road surface structure, belonging to a semi-rigid plate bearing structure design. Inside the road inspection wells, reinforced concrete is based, concrete block or brick masonry is a well in the well, and the well is used 2: 8 gray soil or grade sandstone backfill, reinforced concrete prefabricated or block (brick) masonry, pneumo The cast iron well ring (cover) is wrapped in a C30 concrete, 25 cm thick C30 concrete, and is reserved for 4 cm thickness, which is a rigid structure desig...

Problems solved by technology

[0003] The traditional manhole cover method uses red bricks to adjust the elevation of the wellhead to support the manhole cover support. Due to the poor compressive capacity of the red bricks, the repaired manhole cover will still sink after frequent rolling by vehicles.
