The periphery of the well is generally built by bricks or special materials for well building, a well cover support is built at the upper opening of the well, the well cover is covered on the well cover support, and finally the ground is paved to ensure that the ground is as high as the well cover. Due to the fact that the well is dug, the geological structure below the well cover is changed compared with geological structures in other places, the well cover and the well cover support can sink together, and particularly the well cover on the road is easy to sink. The well lid support is lifted off, the height of the well lid support is made to be the same as that of the surrounding road surface, and finally the damaged road surface of the well lid support is repaired. The invention provides a height-adjustable well lid support, which can be adjusted to be high at any time when a well lid and a well lid support slightly sink, and the trouble of taking off a road and repairing the road is saved.

Background

The inspection well is generally an access to underground facilities, and at present, underground facilities such as tap water, drainage, telecommunication, electric power, gas, heat, fire hydrant, valves, environmental sanitation and the like are generally used as access to the ground. The manhole cover of the inspection well is generally divided into a metal manhole cover, a high-strength steel fiber cement concrete manhole cover, a regenerated resin manhole cover, a polymer matrix composite manhole cover and the like according to materials. Generally, the shape of the material may be round, square, rectangular, etc. The functions are divided into closed, perforated, net-cut and the like. No matter which kind of well lid, it all comprises support and well lid, and the support is that the well lid is fixed in the well head part, and the well lid covers on the support, and well lid and support generally are collectively called the well lid, and current support and well lid can not the height-adjusting. The height-adjustable well lid support comprises a fixed support and an adjustable support, wherein the height of the adjustable support can be adjusted at any time by the adjustable support, and the height of the well lid can be adjusted by adjusting the height of the adjustable support.

Disclosure of Invention

In order to solve the problem that the height of a common inspection well cover cannot be adjusted, the invention provides the height-adjustable well cover support which can adjust the height of the well cover at any time.

The technical scheme adopted by the invention for solving the technical problems is as follows: the well lid support is designed into two parts, one part is a fixed support which can be built in a wall around a well or on the wall, the other part is an adjustable support with adjustable height, and a bolt is designed for adjusting the height of the adjustable support. The technical characteristics of the height-adjustable manhole cover support are specifically described below by taking a round manhole as an example. The circular well needs to use a cylindrical fixed support and an adjustable support, an annular fixed brim in the shape of a hat brim is arranged upwards on the outer surface of the fixed support, and the plane where the annular fixed brim is located is vertical to the axial lead of the cylindrical fixed support. The annular fixed eaves can set up in fixing support's centre or lower oral area, sets up and just can build the fixed eaves of annular in the wall of a well in these two positions, sets up the fixed eaves of annular in fixing support's upper oral area, just can build the fixed eaves of annular on the wall of the well head of brick. The annular fixed eaves can make the fixing support obtain fully fixed. Four flat rectangular fixing handles are uniformly and horizontally arranged on the inner surface of the periphery of the fixing support, which is 20 cm away from the edge of the upper opening, the plane of the fixing handles is vertical to the axial lead of the cylindrical fixing support, one end of each fixing handle is fixed on the inner surface of the fixing support, the other end of each fixing handle is made into a semicircle, a nut clamping hole in a hexagonal nut shape is dug above the fixing handle, the nut clamping hole can clamp a nut so that the nut cannot rotate together with a bolt, the fixing handle is not dug through the hole, a bolt passing hole is drilled in the middle of the nut clamping hole and used for passing through the bolt, the bolt passing hole can only pass through the bolt and cannot pass through the nut on the bolt, and the bolt passing hole is called a bolt passing hole on the fixing handle. The bolt of taking the nut injects in the bolt hole of crossing on the fixed handle, and the nut can block in the nut card hole, and no matter how twist the bolt, the nut can not follow the rotation, and the back and forth is twisted the bolt like this, and the bolt has just can reciprocate in the bolt hole of crossing of fixed handle. The quantity that such fixed handle set up can be decided according to the weight size that the well lid needs to bear, for example the well lid on the road surface, the weight that needs to bear is big, just can set up six or eight fixed handles.

The radius of the outer diameter of the cylinder of the adjustable support is 5 mm smaller than that of the inner diameter of the fixed support, and the purpose of the radius of the outer diameter of the cylinder of the adjustable support is to leave a gap so that the adjustable support can freely move up and down in the fixed support. The supporting handles with the same shape and quantity as the fixed handles of the fixed support are uniformly and horizontally arranged on the inner surface of the periphery of the adjustable support, which is 20 cm away from the edge of the lower opening, the plane where the supporting handles are located is vertical to the axial lead of the cylindrical adjustable support, an inverted U-shaped handle passing groove is vertically and downwards formed in the cylinder wall of the adjustable support right below the supporting handles, and the width of the handle passing groove is 6 mm larger than that of the fixed handles of the fixed support. Therefore, the adjustable support is inserted into the fixed support, the fixed handle is inserted into the handle passing groove on the adjustable support, and the fixed handle can be close to the support handle. The width of the handle passing groove is 6 mm larger than that of the fixed handle of the fixed support, namely, a gap of 3 mm is respectively reserved between the two sides of the fixed handle and the handle passing groove. A bolt passing hole in the supporting handle is vertically formed in the supporting handle corresponding to the bolt passing hole in the fixing handle, and the two bolt passing holes are used for allowing the same bolt to pass through. The upper opening of the adjustable support is designed into a structural shape that the well lid can be buckled on the upper opening of the adjustable support, and the edges of the upper openings of the well lid and the adjustable support are flat.

The structural shape of a bolt passing through two bolt holes is as follows: an annular support ring is fixedly arranged on a screw rod of the bolt, the annular support ring cannot rotate on the bolt, and the diameter of the support ring is as long as that of a hexagon circumcircle of a nut matched with the bolt. The screw thread is left to one section upward screw rod of support ring, and the length of this section threaded screw rod equals the thickness of a nut plus the thickness of two gaskets plus the thickness of supporting the handle. The section of the threaded screw rod which is upward is not provided with threads, the section of the threaded screw rod which is not provided with threads is processed into a square screw rod, the square screw rod can be sleeved with a nut which is used with the lower bolt in a matched mode, the length of the section of the square screw rod is equal to the thickness of the nut, a wrench can be used for clamping the section of the square screw rod to screw the whole bolt and the annular support ring, and the section of the square screw rod is the upper end of the bolt. The annular support ring is all equipped with the screw thread to the screw rod that descends, and this section threaded screw rod length equals 20 centimetres, and this section is the lower extreme of bolt.

A nut is screwed to a position close to the annular support ring from the lower end of the bolt, the lower end of the bolt penetrates through a bolt passing hole of the fixed handle of the fixed support from top to bottom, the nut on the bolt is clamped into a nut clamping hole of the fixed handle, a gasket is sleeved on the lower end of the bolt, the nut is screwed up from the lower end of the bolt, the nut is screwed up by a wrench, and the bolt is fixed on the fixed handle of the fixed support. The same bolt is fixed on each fixed handle of the fixed support seat by the same method. The upper end of each bolt is sleeved with a gasket downwards, the adjustable support is inserted into the fixed support from top to bottom, the fixed handle of the fixed support is inserted into the handle passing groove of the adjustable support, the upper end of each bolt is inserted into the bolt passing hole of the support handle of the adjustable support, a nut is screwed downwards from the upper end of each bolt after the gasket is sleeved downwards from the upper end of each bolt, and the nut is screwed by a spanner. The well lid is buckled on the upper opening of the adjustable support, and the whole well lid is assembled and can be used. When the adjustable support is used, the layer of isolation paper is attached to the outer surface of the adjustable support, so that the outer surface of the adjustable support is prevented from being adhered to the surrounding floor paving material, and the ground is not damaged when the adjustable support is lifted.

When such well lid dress is on the inspection shaft, if a period of time, the well lid has sunk, at this moment just need heighten the well lid. The uppermost nut of each bolt is first unscrewed and the lowermost nut of each bolt is unscrewed a suitable distance. Firstly, three bolts which are evenly distributed in a triangular shape are selected. The spanner is clamped on the square screw at the upper end of the bolt, the screw is screwed in the direction of nut dismounting, because the nut is clamped in the nut clamping hole of the fixed support fixed handle on the bolt, the length of the screw between the fixed support fixed handle and the adjustable support supporting handle is increased, the adjustable support is jacked up by the annular supporting ring, the adjustable support is heightened, and when the upper opening edge of the adjustable support is heightened as the ground around, the nuts at the upper end and the lower end of the three bolts can be screwed up and screwed down again. Then adjusting the length of a screw rod of other bolts between the fixing handle and the supporting handle to enable nuts between the fixing handle and the supporting handle to be clamped into nut clamping holes, enabling an annular supporting ring of the bolts to tightly support the supporting handle, then screwing down the nuts at the lowest part of the bolts, screwing down the nuts which are detached at the upper ends of the bolts and screwing down the nuts. If necessary, the ground around the well cover is filled with proper materials, and the well cover is lifted.

The invention has the beneficial effects that: for example, when a newly built road surface is built, it is likely that all manhole covers sink to different degrees half a year later, and the wheels roll on the manhole covers, and "bang bang" makes a sound. Because of the sinking of the well lid, the road surface is uneven, resulting in that the road surface around the well lid is more easily damaged than other places. The support of well lid can not be taken off at once to the road of newly repairing, raises the well lid again, generally can give its development to, until the road surface around the well lid destroys to certain degree after the past several years, when this piece of road surface also can't use again, wait new road become after the old way, just take off the well lid and redo. The height-adjustable well lid support is different from the height-adjustable well lid support, if the well lid slightly sinks, the height can be adjusted at any time, the well lid support does not need to be taken off, the well lid is increased, the road surface is repaired again, and unnecessary waste and troubles are caused. The vehicle does not need to be driven on a newly-built road surface, and the 'bang bang' sound due to uneven well cover rolling, so that the vehicle is inconvenient to drive for many years.
