Description
Technical Field
The invention relates to a well lid repairing method, in particular to a repairing construction method of an integrated pressure-resistant well lid.
Background
At present, the problem of collapse of the road surface around the manhole cover is 5% of the problem of damage and noise caused by the quality problem of the manhole cover, but 95% of the problem is that the road surface around the manhole cover collapses or the foundation of the manhole cover collapses. The main reasons for the collapse of the road surface around the well lid and the collapse of the well lid foundation are the design defects of the traditional well lid. The traditional method for repairing the damaged pavement around the well cover mainly comprises the steps of digging out and grooving the asphalt pavement in the area range near the well cover for forming, filling the periphery of the well cover with cold-mixed asphalt mixture or hot-mixed asphalt mixture, and then performing construction compaction. Traditional well lid installation construction, need use concrete placement to come unable adjustment base during the maintenance, need seven days before and after the construction just can be under construction and lay pitch, the time limit for a project is longer, influences the normal current of road, and the maintenance that the construction is complicated and the maintenance back road surface needs certain time during the change leads to the fact certain traffic pressure to urban road, especially to the great road of vehicle flow, changes well lid maintenance road surface and becomes more difficult. On the other hand, the upper surface on the peripheral road surface of well lid is restoreed the back and can not guarantee the parallel and level with the road surface, influences the travelling comfort that vehicle and pedestrian passed through.
To current well lid at vehicle roll compaction in-process atress concentrate on the well seat, the atress is uneven, easily causes the problem that the road surface sinks around the well lid, has redesigned the structure of well lid among the prior art, has made the adjustment to the well lid structure from the angle of the atress area and the atress principle of well lid, forms integration resistance to compression well lid (like the well lid of the disclosure of CN201510746411, CN 201510746411). This kind of integration resistance to compression well lid passes through outer walling crib and forms integrated structure with the road surface around the well lid, has improved the compressive strength of well lid. The installation process of present integration resistance to compression well lid when being used for restoreing does: a pit is arranged at the damaged part around the well lid, and a hoisting gap is expanded outside the edge of the pit, so that a gap is reserved between the edge of the pit and the well lid ring body, and the well lid ring is favorably hoisted into the pit; and hoisting the well lid body to the well lid ring body. In the construction method in the prior art, after the ring body is hoisted, a gap exists between the ring body and the pit, a small amount of concrete can be poured in the gap, and the construction efficiency is improved.
However, in the process of repairing and installing the existing integrated pressure-resistant well lid, after the ring body is hoisted into the pit, the gap between the ring body and the pit needs to be additionally subjected to crack pouring operation, the construction steps are not simple enough, and the crack pouring work needs to be performed carefully to ensure that the heights of the well lid, the crack pouring and the road surface are kept consistent after the crack pouring. If the crack is not filled enough, a certain cavity and a loose part exist between the repair material base layer below the well lid and the side wall of the well lid mounting hole, in the vehicle rolling process, the difference exists between the strain generated by the bearing stress of the cavity and the loose part and the strain generated by the bearing stress of the repair material filled part, so that the repair material base layer is separated from the well ring mounting hole, and the periphery of the well lid is damaged. Therefore, although the integrated pressure-resistant well lid can structurally solve the phenomena of peripheral collapse and damage, the seam filling process enables the seam filling and the well lid foundation to be not of an integrated structure, and the unreasonable installation mode can also cause the reduction of the effect of the integrated pressure-resistant well lid.
