Description

A kind of well lid

Technical field

The utility model relates to a kind of additional facilities of burying pipeline below the road underground of being convenient to check, specifically is the well lid on a kind of road surface.

Background technology

The well lid of the various pipelines that are provided with on the present road, when vehicles or pedestrians pass through, through under the pressurized situation repeatedly, tend to produce this phenomenon, top cover perk, sideslip, fracture as well lid, ftracture between well seat and the road surface, come off, subside, or not that well lid is higher than the road surface, is exactly to be lower than the road surface, or top cover is usually lost, brought very big danger for vehicle and pedestrian, contingency often has generation, and property and life have been subjected to infringement, its reason is to cause problem to be solved in the utility model that Here it is by the structural unreasonable institute of existing well lid.

The utility model content

The purpose of this utility model be to provide at the shortcoming of above-mentioned existence a kind of well seat combine with the road surface good integrity, pressure-bearing can not ftracture with come off, top cover can perk, the well lid of sideslip, fracture

The purpose of this utility model is achieved in that a kind of well lid, comprises top cover, well seat and locking device, and its described top cover is a bullet, and capping is provided with lockhole; Described well seat is one for being connected with steel rib concrete two parts by ironcasting, and described ironcasting and edge, steel rib concrete junction are for being terraced steps; Described locking device is made of locking bar, tapered end, retainer and the jump ring of band plug.

In above-mentioned, described cap base edge is a fillet; Described well seat inside edge boss is provided with uniform groove; Described retainer is fixed on the well seat ironcasting lateral wall.

The utility model adopts above-mentioned design scheme, and it is rational in infrastructure, compressive resistance is high, and the well seat combines good integrity with the road surface, can not ftracture and come off, top cover can perk and sideslip, is difficult for losing yet, prolong road service life, reduced traffic accident, guaranteed vehicle and pedestrian's safety.

The specific embodiment

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Shown in Fig. 1-5, a kind of well lid comprises top cover 1, well seat 2 and locking device, and its top cover 1 is designed to bullet, can avoid perk, sideslip or the fracture of top cover 1 like this, has also strengthened the compressive resistance of top cover 1 simultaneously, also is provided with lockhole 3 on its capping; Its well seat 2 is one for being connected by cast with steel rib concrete 5 two parts by ironcasting 4, well seat 2 compression areas have been enlarged, improved bearing strength, and kept it to combine with the road surface globality, do not ftracture, come off around can not causing well seat 2, its ironcasting 4 and edge, steel rib concrete 5 junction be for being terraced steps 6, and its effect is in order to improve the fastness that combines of ironcasting 4 and steel rib concrete 5, to guarantee its bearing strength; Described locking device is made of locking bar 8, tapered end 9, retainer 10 and the jump ring 11 of band plug 7, and its effect is that top cover 1 and well seat 2 are pinned, and prevents that top cover from losing.In addition, its top cover 1 bottom margin is designed to fillet, is convenient to top cover 1 and lifts or cover and be not stuck; Its well seat inside edge boss 13 is provided with uniform groove 14, can contain the stone or the hard foreign material that fall above, stone drops and cause 1 perk of Gai Buyan top cover or sideslip between top cover 1 and well seat 2 when avoiding top cover 1 to lift or cover, and keeps the planarization on road surface; Its retainer 10 is weldingly fixed on ironcasting 4 lateral walls below the well head, and the locking bar 8 of being convenient to locking device passes its retainer 10, and top cover 1 is pinned on well seat 2, avoids separating of top cover 1 and well seat 2.

During installation, at first by locking bar 8 one ends by the lockhole 3 on 1 of the top cover, pass retainer 10 fixing on ironcasting 4 outsides again, put tapered end 9 then and embed jump ring 11, with the vexed tapered end 9 that presses solidly in its locking bar 8 ends, its other end blocks top cover 1 by plug 7, make top cover 1 and well seat 2 movable pinnings together, both be convenient to top cover 1 and lifted or cover, and can not make top cover 1 again, and prevented to lose or stolen away from well seat 2.During construction, the well lid integral body that top cover 1 and well seat 2 are connected together is shelved on above the tired in advance good well head, tamps the space between well seat 2 and the road surface floating with concrete then.After solidifying, guaranteed that well seat 2 combines with the integral body on road surface, can not produce cracking, obscission by pressurized, kept path formation, reduced contingency because of pedestrian or vehicle.
