Description
Technical field
The present invention relates to a kind of upper maintenance method for overhauling well, more specifically be, the basic packing material that uses during inspection-pit rising maintenance construction is relative with the durability of road surface packing material high, make inspection-pit maintenance work number of times significantly reduce the raising economy, the sclerosis service time of basis packing material and road surface packing material obviously reduces, solved and carried out the inconvenience that long-term traffic control brings, not only the inspection-pit maintenance works is easy, can also guarantee inspection-pit maintenance personal's safety, ensure durability and the flatness on road surface and the safe passing of vehicle after the inspection-pit maintenance is finished, prevent that the intensity of well lid bracing frame from reducing.
Background technology
Usually, burying various facilities such as upper hose, sewer pipe, cable, the communications cable under the road underground, these facilities will be safeguarded at any time because of need.Therefore, the various facility things in order to safeguard that road is underground are provided with inspection-pit every a segment distance.
The inspection-pit structure of initial construction when Fig. 1 shows road construction.According to shown in Figure 1, the underground inspection-pit sleeve pipe of burying underground with the circular hollow bulb of having of subterranean pipe line UNICOM (12) (10), laying the cylindrical shape well lid bracing frame (20) of metal material above the inspection-pit sleeve pipe (10), the well lid (22) of metal material is being laid in the upper end of well lid bracing frame (20).Pack with base material and skin-material successively in the outside of well lid bracing frame (20), forms the supercrust (24) of road.
Construction back road is because vehicle current is subjected to loading repeatedly, and the domain begins to sink, so the road surface has and splits or damaged.Therefore, be the cycle to carry out reinstatement works approximately with 5 years, go up formation covering layer (16) at supercrust (24), the upper end of well lid bracing frame (20) is lower than the surface of covering layer (16), cave in than pavement of road in the inspection-pit position, thus the advanced before height of being about to inspection-pit of redeck layer (24) rise be adjusted to supercrust (24) on covering layer (16) highly consistent.
And, vehicles or pedestrians continue the current inspection-pit of building on the road that makes, continue to stand vibrations and weight, the fragment of brick (14) that causes supporting inspection-pit splits or is pressed against corresponding inboard and caves in, a road surface part is subsided, and the inspection-pit of the inspection-pit height that also needs this moment to rise is safeguarded and is constructed.Especially, to being arranged on the inspection-pit of tilted road surface, it subsides more serious, safeguards construction so can carry out the inspection-pit of tilted road surface more continually.
Inspection-pit rises, and safeguarding constructs is undertaken by following program, and excavating with equipments such as cutting machine or excavators on every side of the well lid bracing frame that will subside removed.Then, utilize the Height Adjustment equipment that well lid bracing frame upper end Height Adjustment is become consistent with the height of supercrust.Under the state that the Height Adjustment of well lid bracing frame is maintained an equal level to the height with the road surface, around the well lid bracing frame, fill basic packing material and sclerosis, on basic packing material, fill the completion material then and harden, finish the inspection-pit maintenance work.
But, traditional inspection-pit method for maintaining, the durability of gene basis packing material mediation completion material is relatively low, so need often carry out the inspection-pit maintenance construction.And basic packing material is relative longer with the sclerosis conditioned time of completion material, need carry out the traffic control of long period and bring inconvenience, uses vibration equipment with also needing filling and reinforcing outward, so the inspection-pit maintenance construction can be very loaded down with trivial details.
In addition, the inspection-pit climb procedure of adjusting the inspection-pit height on the traditional approach has, use height adjusting ring method, withstand well lid bracing frame (20) with spring below, the method of adjusting from top tightening nuts or with brick or stone pad below inspection-pit well lid bracing frame, the method that the potting resin concrete is adjusted, do not excavate the road surface, the method that fixing height adjusting ring made of iron is adjusted on well lid bracing frame (20) etc.
But above-mentioned conventional construction method need carry out numerous constructors heavy well lid (22) and bracing frame (10) are all lifted to risky operation on the supercrust (24).And, the brick (14) piled up on the inspection-pit sleeve pipe (10) all need be removed, the upper end of inspection-pit sleeve pipe (10) hollow bulb (12) is exposed, then through behind thorough cleaning inspection-pit sleeve pipe (10) upper end, the height adjusting ring of installation specificationization again.In this case, can only adjust by the certain thickness that height adjusting ring has been set, inspection-pit after the rising is than road surface or high or low, even maintenance construction through inspection-pit, the flatness of road still is not good enough, take place damagedly on the inspection-pit well lid bracing frame with the fixing height adjusting ring of screw and hold-down screw and nut under the weight of impact of vehicle pass-through and vibrations easily, cause height adjusting ring loosening, this is that supercrust (24) splits or another damaged reason.
And, withstand the method for well lid bracing frame (20) with spring from top tightening nuts, for spring being installed in below the inspection-pit well lid bracing frame, need carry out heavy well lid bracing frame (20) is brought up to the above risky operation of height of spring, but also exist lifting height will reach the above limitation that could use spring of spring thickness at least.
Also have, need not to excavate the road surface, insert height adjusting ring made of iron in the upper end of well lid bracing frame (20) and fix, the method for adjusting the inspection-pit height also is to adopt normalized height adjusting ring to install.Because can only adjust the height of inspection-pit by the certain thickness that height adjusting ring has been set, the inspection-pit after the rising influences the flatness of sideways inclined face than road surface or high or low.
In addition, adjust behind the height between bottom that the inspection-pit well lid supports and inspection-pit sleeve pipe (10) and produce the space, fill plaster or other packing materials in the space to be used as mould behind thin plywood or plastic board material or the automobile tyre inflation.
But, adopt light sheet or doughnut as mould during packing material, the jog on inspection-pit sleeve pipe (10) or well lid bracing frame (20) surface is not sealed fully, the situation that causes packing material to ooze out more often takes place, fail the dense packing material that fills up, cause intensity to reduce, the bed knife of well lid bracing frame (20) also reduces thereupon.
Summary of the invention
In order to address the above problem, it is relative with the durability of road surface packing material higher to the invention provides the basic packing material that uses when a kind of inspection-pit rising is safeguarded, significantly reduce the inspection-pit maintenance times, increase economic efficiency, obviously shorten the sclerosis conditioned time of basic packing material and road surface packing material, eliminate and carry out the inconvenience that traffic control brings for a long time, do not need the easy inspection-pit rising maintaining method of filling and reinforcing with the vibrations equipment.
And, omitted the Maintenance and Repair well and the dangerous work of lifting heavy well lid bracing frame, adopt the inspection-pit rising maintaining method that easy method is adjusted to the lifting height of inspection-pit and the road surface accurately maintains an equal level.
And, of the present inventionly be intended to provide, can confirm with the naked eye when adjusting the inspection-pit height that the lifting height of inspection-pit can simply be adjusted height rapidly, and not produce concavo-convexly between the pavement of road, correctly carry out the inspection-pit rising maintaining method that inspection-pit is safeguarded.
