Abstract
The invention discloses a calibration method for lifting of a movable examination well shutter, comprising the following steps of: (1) adding an isolation ring out of a well shutter combination formed by the movable examination well shutter and a well base; (2) reserving reinforcing steel bars on the periphery of the isolating ring, burying the reserved reinforcing steel bars into ground to form a material integrated with the ground; (3) when the well shutter combination is placed in the isolation ring, reserving a gasket and an embedded fixing clip between the well shutter combination and the isolation ring; (4) arranging a cushion layer at the lower edge of the well shutter combination and the isolation ring and reserving a gap therebetween; (5) when maintenance is required, inserting a crowbar into the gap, prying the movable examination well shutter combination, and placing a special gasket between the well shutter combination and the isolation ring if the movable examination well shutter combination is needed to raise to the normal position; and on the contrary, extracting the reserved gasket between the well shutter combination and the isolation ring. The invention can solve the repairing problem of the well base of an examination well which sinks, raises or tilts under pressure. And the maintenance is dry operation which can be accomplished within an hour, thereby not causing traffic jam, easing the labor intensity and having low cost and high efficiency.
Description
Technical field
The present invention relates to be used for checking the manhole cover of facilities such as underground pipeline, cable, optical cable,, relate in particular to the bearing calibration of its lifting in particular to movable examination well shutter.
Background technology
Traditional manhole cover such as traditional drainage inspection well, rainwater inspection well, sewage manhole often exists the heavy under pressure or inclination of well seat, well lid is easily pushed by wheel and shortcoming such as rout up.And the maintenance of sinking or tilting for well lid, traditional method be adopt manually excavate, levelling again, concrete pouring solidify construction that takes 10 days at the soonest and concrete curing phase.Not only cost height, cycle are long for this, and are wet works.Also can cause the maintenance interval traffic to be obstructed.These problem already cause people's attention.The Chinese patent application part that relates to manhole and well lid thereof reaches thousands of, and most technical schemes are to improve from structure and material.As CN00112189.8 " plumbing manhole cover, seat and production technology thereof ", CN00132052.1 " manhole cover made of composite material and well seat ", CN200310112674.2 " pipe type manhole ", CN03131811.8 " integral type pipe manhole " etc.But thoroughly do not solve the maintenance shortcoming that existing manhole exists yet.For this reason, the inventor is the bearing platform type manhole of development of new once, and relevant patent has " bearing platform type safety manhole " No. 200510003298.2, and its advantage is durable, can ensure driving and pedestrian's safety.But this bearing platform type manhole mainly is divided into well base, pit shaft, well seat, walling crib, cushion cap and well lid, and the structure of whole manhole is comparatively complicated, and cost is higher, and construction is trouble comparatively; Its maintenance is proofreaied and correct to be needed with the use jack, and the manhole of sinking is raise, and just is difficult to keep in repair for reduce the manhole of giving prominence to owing to ground.
Summary of the invention
The object of the present invention is to provide a kind of bearing calibration of lifting of movable examination well shutter,, easily various manhole covers are keeped in repair correction to overcome the shortcoming of prior art.
For reaching goal of the invention, the inventor at movable examination well shutter be meant have well lid, the manhole of well seat and pit shaft, also contain the manhole that cushion cap is arranged certainly, its bearing calibration comprises:
1. the periphery of the well lid combination that constitutes at movable examination well shutter and well seat thereof increases cage ring, and its inner ring just in time holds the well lid combination; Cage ring is isolated well lid combination and road surface constituent material;
2. at the neighboring of cage ring reserved steel bar, during use the reinforcing bar of reserving is imbedded within the constituent material on ground, be combined into integral body with the ground constituent material;
3. when cage ring is inserted in the well lid combination, between well lid combination and cage ring, embed fixation clamp;
4. in the lower edge of cage ring and well lid combination bed course is set, therebetween preset clearance;
5. when needing repairing the manhole cover of that proofread and correct or that raise or inclination, insert the gap with crowbar or ultrathin jack, the manhole cover combination is levered up or jack-up, make its rising make the well seat recover the normal position if desired, just between well lid combination and cage ring, insert special pad and make its rising; Make its decline make the well seat recover the normal position if desired, just between well lid combination and cage ring, extract the pad of reserving out and make its reduction.
Attention is filled the pitch ointment in the gap between cage ring and well seat, prevents that rainwater from infiltrating in the well.
Above-mentioned road surface constituent material comprises the concrete bed course, asphalt concrete layer, the composite bed of concrete layer and bituminous concrete.
Above-mentioned manhole cover front has center screw, also has two lifting handles; The middle part of reverse side is the load round platform that has screw, also has reinforcing rib radially; Well lid is fixed on the load round platform by securing member, and embeds the well seat, and well seat, well lid are linked to be integral body, forms the well lid combination.
The quantity of the peripheral reserved steel bar of above-mentioned cage ring is 1～6 row, and the length of every reinforcing bar is 200～600mm, wherein 60%～70% imbeds within the constituent material of ground.
Reserving the pad gross thickness between combination of above-mentioned well lid and the cage ring is 10～80mm, is that the pad of 10mm, 20mm, 30mm, 50mm is formed by stacking by thickness respectively.
The preset clearance of above-mentioned bed course is parallel clearance or oblique gap, and gradient is 0 °～50 °.
The inventor points out, because the reinforcing bar that cage ring is reserved is imbedded within the constituent material of ground, is combined into integral body with ground, so the problem of change in location can not appear in cage ring substantially, and the problem of having only the well lid combination just to have sinking, raise or tilt; Therefore as long as reserve pad and preset clearance, unclamp the fixation clamp that embeds between well lid combination and the cage ring and just can keep in repair the rectifying inspection well lid easily.
The method that lifting of movable examination well shutter provided by the present invention is proofreaied and correct can solve the reparation problem of the sedimentation under pressure of manhole well seat, rising or inclination like a cork; And maintenance to proofread and correct be the dry farming industry, only must can finish in one hour, can not cause traffic jam, alleviate the labour intensity that the manhole maintenance is proofreaied and correct, maintenance cost is low, efficient is high.Be applicable to movable examination well shutter.
