Description

Wellhead maintenance method and device thereof

Technical field

Wellhead maintenance method of the present invention and device thereof are in order to solve asphalt road ... wait on the road because of awarding the damage that lasting downforce causes in a large amount of vehicle pass-through processes, the variation of temperature and the expansion that produces, the stone that breakage that shrinkage phenomenon causes and rainy season lay below to asphalt road, the problems such as loss of basic material such as sand, when carrying out road upkeep to tarmac road repeatedly shop oil and the well head that causes problem such as sink.Specific description is exactly the pulverizing arbor that uses with device in conjunction with wellhead maintenance and pulverize the novel pulverizing cutter sweep that gear (ColdmillingWheel) and cutter are combined into one; and this pulverizing cutter sweep of use is to pulverize simultaneously and cutting work to wellhead maintenance method; finish maintenance like this in short time and on cost, save construction cost; reduce the generation of pollutants such as drifting along on the meaning of environmental protection, traffic jam can not take place aspect traffic.

Background technology

Generally, the underground meeting of road is provided with a lot of upper hoses, sewer pipe, and power cable, various facility things such as communication cable will keep in repair as required to these various facilities.At the road surface certain intervals well head is set like this, keeps in repair underground facility.But the expansion that the following recast repeatedly when understanding because of vehicle ' is used or the variation of temperature causes, shrink and because the arrival in strong rainy season makes the stone below the asphalt road, the losses of basic material such as sand etc. produce sinking of ground, and cause the crackle and the damage on road surface.Sinking like this, crackle and damage can cause the vehicle safety of road driving, so can regularly carry out operation again (covering (Overlay) construction) to the road surface of breakage, make like this on the supercrust of road and form covering layer, the well lid upper end can reduce than cover surface, form hollow, so will before road covers again, the Height Adjustment to well head arrive the operation consistent with the road surface covering layer.

Also have, the well head in the road after the construction is because vehicles or pedestrians current, the vibrations of generation and heavy down and cause the well head supporter to be pulverized decline occurring allowing a road part sink, and this situation also will be adjusted the construction of height to well head.Particularly well head decline phenomenon appears in the well head that is provided with on the slope course, well head is carried out in the slope course safeguard construction.

Even a lot of to having now of such wellhead maintenance construction, existing method for maintaining and the device introduction that is just using is as follows.

Raise construction method by the height spacer is arranged in order to adjust well head that the well head height that descends than the road surface uses, spring below the well lid support supports the method for adjusting with nut, pad such as also useful brick or stone is below well lid, inserting resin, cement etc. are regulated well head control methods such as well head height, but above-mentioned existing wellhead maintenance method has following problem when the construction of maintenance well head.

At first, height spacer by the certain thickness specification is fixed on the situation that improves the well head height on the support of well lid with screw etc., most constructors will be the weight thing that well lid and support all are placed on the road surface, removing the brick at well head edge etc. then, the well head hollow bulb is exposed to the outside, after the edge of well head cleaned, certain specification Height Adjustment pad is being provided with, the height spacer of making according to certain specification as this situation, so must regulate the high or short situation that when raising, can occur according to thickness than the road surface, even if neither be very smooth so carried out the wellhead maintenance builder's road, be fixed on screw and heavily reach vibrations under the impact can be because of vehicle pass-through time of height spacer on the well lid frame and set bolt and nut and be very easy to damage and make the height spacer loosening, this also can become pavement crack or damage reasons.

Also have, when using the holder of spring handle well lid frame to come control method with hold-down nut in the above, will to carry out the weight thing under the well lid frame be that well lid and support all are placed on the dangerous work on the road surface for spring is placed on, Cai also have minimum rise height than the high operable problem of spring original length.

Also have, need not excavate the method that the road surface height spacer that adding is made with iron material on the well lid frame is fixedly regulated the well head height later on, it so also is the height spacer that will use certain specification, this situation forms the height that well head is regulated according to height spacer height, so having the well head of rise takes place than road surface or high or low situation, highly regulate well lid frame bottom surface, back and well head frame in addition and can produce the slit, when in the slit, using plaster or other filler to fill with thin plate or plastic plate or at automobile tyre inflation later on as casting mold.

But when using the doughnut of thin plate or inflation with casting mold when using filler to fill, on the jog on well head periphery or well lid frame surface can not be blocked completely, the situation that filler spills from the slit is relatively more multiple, make filler compact inadequately, cause intensity to descend, the problem that the bed knife of well lid frame descends occurs.

In order to solve the problem in the said method, and is using the construction plant of the method that produces part maintenance now, the method is exactly the suitable radius size to the well head periphery, after the cut-out of pitch cutting machine, inboard at section is that the electric drill instrument is removed the rubbish such as pitch of well head periphery with breaker (Breaker), the method for maintaining that above-mentioned well head is clawed outward with gravitation or crane, but when having construction, such method can produce very big noise and pungent dust in the process of above-mentioned breaker (electric drill) removing pitch, the noise and the dust public hazards that produce during because of wellhead maintenance when generally safeguarding the well head in the road of residential district make a lot of residents produce resentment; Simultaneously the time of maintenance construction need very long, on one side under the road situation of interrupting, can worsen the problem of traffic jam, also have, the construction of manpower all lean in all work, makes constructor's fatigue strength increase the problem of construction ability decline in nature.

In addition, after using the cutting machine that is attached with built-in hydraulic cylinder pulverizing cutter sweep that the neighboring in the well head proper range is cut according to circle during wellhead maintenance construction recently, after auxiliary materials such as the pitch in the radius between the neighboring of well head and cutting, stone, sand are pulverized with mill, auxiliary materials such as the pitch of pulverizing, stone, sand are removed, with well head rise device well head is being keeped in repair, but cut like this and pulverize and to construct successively, the maintenance time that needs is very long, and construction cost also can increase thereupon; And the problem of the environmental hazards that the peripheral dust that produces during construction causes; The existence such as problem of the severe exacerbation traffic jam that the stage casing on cause one side line road produces.

Summary of the invention
