Detailed Description
In order to make the technical purpose, technical scheme and beneficial effect of the present utility model more clear, the technical scheme of the present utility model is further described below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, the concrete embodiment of the highway underlying abandoned manhole cover cap structure according to the present utility model includes a foundation support portion 4 for pouring on the peripheral side of the abandoned vertical shaft 3, the foundation support portion 4 is an annular strip foundation formed by pouring reinforced concrete at 1.0m outside the abandoned vertical shaft 3, the annular strip foundation needs to be subjected to stress calculation, and the upper end surface of the annular strip foundation is flush with the upper end surface of the abandoned vertical shaft 3. In this embodiment, the foundation support portion 4 adopts a cylindrical structure, and is sleeved outside the abandoned vertical shaft 3, and when the foundation support portion is actually poured, after ditching through the original ground 1, the ditch bottom directly supports the foundation support portion 4 effectively.
The above-mentioned foundation supporting part 4 is poured with a hemispherical cap part 5 for covering the top of the wellhead of the abandoned vertical shaft 3, specifically, the upper end surfaces of the annular strip foundation and the abandoned vertical shaft 3 are used as supports, a hemispherical template is erected, the hemispherical template is solid and light and can be customized by foam processing, concrete is poured on the hemispherical template, and the thickness of the concrete is calculated according to the thickness of the future covering soil of the cap until the design strength is reached. Through pouring the laminating of week side bottom and the up end department of basic supporting part 4 of hemisphere block portion 5 and be connected, and because annular bar basis up end and abandonment vertical 3's up end parallel and level set up, can realize closely laminating between the bottom and the well head of this hemisphere block portion 5. The cross section of the base support portion 4 is annular, and the outer diameter of the base support portion 4 is identical to the outer diameter of the hemispherical cap portion 5.
The capping process is as follows: step one: the newly built highway passes through the abandoned vertical shaft 3 of the old mining area, and an annular strip foundation is poured by reinforced concrete at a position 1.0m outside the abandoned vertical shaft 3, and the annular strip foundation is subjected to force calculation; the annular strip-shaped base surface is flush with the upper surface of the waste vertical shaft 3;
step two: taking the annular strip foundation and the surface of the abandoned vertical shaft 3 as supports, erecting a hemispherical template, wherein the hemispherical template is solid and light and can be manufactured by foam processing and customization;
step three: pouring concrete on the hemispherical foam template, calculating the thickness of the concrete according to the future covering soil thickness of the cap, and curing the concrete until the concrete reaches the design strength;
step four: after the concrete cap reaches the design strength, the hemispherical cap part 5 is covered by adopting the roadbed filling soil 2, compacted, the roadbed is built, and the highway is paved.
Pouring an annular strip foundation around a wellhead of the abandoned vertical shaft 3, further erecting a template on the annular strip foundation, binding reinforcing steel bars, pouring concrete to form a hemispherical concrete cap, after the concrete reaches the design strength, compacting the filled soil, then paving a roadbed, and compared with the conventional method of treating a plane cover plate, the lower side of the plane cover plate is pulled, the concrete is easy to generate cracks, the reinforcing steel bars are further leaked and corroded, the durability is poor, and the hemispherical concrete cap is integrally compressed, does not have the partial tension condition, fully utilizes the compression resistance of the concrete and has good durability; compared with the existing filling method, the filling method has huge economic cost, and simultaneously faces the problem of large consolidation settlement of the soil body in the later period.
Of course, in other embodiments, the annular strip foundation may be replaced by other structures, such as a polygon; the bottom of the foundation supporting part 4 and the abandoned vertical shaft 3 can be cast together after being built by adopting a module, and the supporting of the hemispherical cap part 5 is realized through the abandoned vertical shaft 3 and the foundation supporting part 4, so that the structure is more stable; the hemispherical cap part 5 can be designed into a hollow structure or a space is formed between the bottom and the upper end of the wellhead, so that materials are saved, and the operations such as removing the templates can be facilitated.
In other embodiments, the space between the base support part 4 and the well wall may not be designed, and the actual size of the space may be arbitrarily designed by those skilled in the art according to actual needs.
Finally, what should be said is: the above embodiments are only for illustrating the technical solution of the present utility model, and any equivalent replacement of the present utility model and modification or partial replacement without departing from the spirit and scope of the present utility model should be covered in the scope of the claims of the present utility model.
