Abstract
Inspection shaft subsides prevents and treats structure, its well base for there is reservation step form at original well base top opening part that digs, the walling crib arrange in original well base to fill between walling crib and well base and pack, the well base of step form in lay steel reinforcement cage and concrete -filled. The utility model discloses have a very strong practicality in that urban road is under construction, it not only adds on cement concrete pavement and bituminous paving and the new road bed of constructing and is suitable for when spreading asphalt concrete, and the inspection shaft of other pipeline facilities of installation adds and can be suitable for equally when spreading the asphalt concrete road surface on urban road moreover, adopt this structure can effectually prevent that the inspection shaft from taking place to subside at the in -process that uses.
Description
Technical field
The utility model belongs to the infrastructure in municipal highway, the manhole depression control structure specifically for preventing manhole from depression in use occurring.
Background technology
In recent years, city size constantly expanded, and infrastructure construction reach quality control is tight and due to reasons such as vehicle flowrate increasings, there is a large amount of manhole depressions and all road surface breakages of well in urban road, affect road occupation effect, smooth degree and difference attractive in appearance, especially affect ride comfort.
Existing manhole construction is after road foundation or basic unit are shaped substantially, in the oppositely rear installation of excavation, then backfill, because excavation caused disturbance to original closely knit roadbed and basic unit, in addition during backfill, work plane is narrow, backfill quality control is not tight, especially original design standard, and walling crib is often less than the scope of excavation disturbance, and be plain concrete substantially, cause the depression of whole manhole, pavement destruction, and then develop into the destruction of manhole and pipeline.
Summary of the invention
The utility model is for the manhole depression control structure of tackling manhole depression situation in urban road., its structure is simple, the basis of original walling crib is set up a circle coagulation pedosphere, prevents depression respond well.
The utility model realizes above-mentioned purpose by the following technical solutions:
Manhole prevention and cure of settlement structure, it is have reserved step-like well base at original well Ji Shangfangkaikouchu dug, and described walling crib is placed in original well base, and fills filler between walling crib and well base; Reinforcing cage is laid and fill concrete in described step-like well base.
Preferably, described reinforcing cage and the top of walling crib link together, and better can ensure the connectivity of concrete outer ring and walling crib in the process of concreting.
The utility model adopts technique scheme to have following beneficial effect:
Although the utility model technical difficulty is little, but there is very strong practicality in urban road construction, it is not only suitable for during Paving Bituminous Concrete on cement concrete pavement and flexible pavement and the roadbed newly built, and can be suitable for equally when installing the manhole Paving Bituminous Concrete road surface of other pipeline facility on urban road; This structure is adopted can effectively to prevent manhole from the process used, sedimentation occurring.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of another embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment 1
As shown in Figure 1 be a kind of embodiment of the present utility model.
Manhole prevention and cure of settlement structure, it is have reserved the second step-like well base 12 at original the first well base 11 upper opening place dug; Walling crib 2 is positioned in the first well base 11, and fills filler 3 between walling crib 2 and the first well base 11.
Reinforcing cage 4 is located in the second well base 12, is skeleton concreting 5 with reinforcing cage 4.
Embodiment 2
Another embodiment of the present utility model as shown in Figure 2.
Manhole prevention and cure of settlement structure, it is have reserved the second step-like well base 12 at original the first well base 11 upper opening place dug; Walling crib 2 is positioned in the first well base 11, and fills filler 3 between walling crib 2 and the first well base 11.
Reinforcing cage 4 is connected to the top of walling crib 2, and when walling crib 2 puts into the first well base 11, reinforcing cage 4 matches with the second well base 12, is skeleton concreting 5 with reinforcing cage 4.
