Description

Adjustable inspection shaft lid

Technical field

The utility model discloses a kind of adjustable inspection shaft lid, belong to the improvement of the inspection shaft lid that urban operating mechanism etc. uses.

Background technology

Along with the continuous development of science and technology with use rapidly, pipeline such as underground various electric power, communication, air feed, heat supply, feedwater, draining or bury underground all constantly acquire, extension, dilatation or transformation, the inspection shaft of various types and inspection shaft lid are used in large quantities.In the prior art, the inspection shaft lid application enhancements of urban operating mechanism such as road, square, greenery patches and dedicated line is upgraded and is mainly contained two aspects, the one, on the basis of the CJ/3012-93 of the Ministry of Construction " casting iron well lid " standard, add anti-theft device, this type of inspection shaft lid is transformed and is belonged to mostly with antitheft innovation.Another kind is to use the improvement that other new composite material is replaced cast iron materials, but its whole primary structure and pattern are parent with the casting iron well lid still.On passing road, the inspection shaft lid that the existing buried type of this class is installed is used the common very big shortcoming that has one, exactly because the sedimentation of inspection shaft lid pedestal, road trimming or construction quality etc. often cause the inspection shaft lid to can not get in conplane assurance with the road surface, thereby bring very big inconvenience for pedestrian and driving, vehicle jolts easily even danger occurs, and after the inspection shaft that existing buried type is installed lid will adjust the plane and the road surface that inspection shaft lid week makes a circle all must be chiseled, could bury installation again, quite trouble and wasting manpower and material resources.

The utility model content

The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of inspection shaft lid that can conveniently adjust height, its structure is simple and direct, material is saved, cheap, easy to operate, result of use is remarkable.

For reaching above purpose, the technical solution adopted in the utility model is: a kind of adjustable inspection shaft lid, comprise that the well lid cooperation places on the interior shoulder of well seat, it is characterized in that: well lid is connected by the bolt that is fixed with nut is installed in the longitudinal hole with the well seat, the upper port of the through hole on the well lid is provided with the interior shoulder that bore matches with nut, and the inboard of well seat is offered and cooperated the horizontal screw that bolt is installed.

The quantity of longitudinal hole and bolt is 3～16, and is distributed on well lid and the well seat.The longitudinal hole of this structure and the minimum number of bolt are 3, mostly are 16 most, between 3～16 several still all belong within the protection domain of this structure naturally.Wherein bolt be used to regulate the well seat whether with the road surface on same plane, and regulate well seat and well lid self about whether with high.

Be provided with the screw thread suitable in the through hole on the interior shoulder of well seat with bolt.

Well lid and well seat adopt concrete and bar pouring to build up any in type, hard plastic moulding, the cast iron moulding.

The flexible space ring of well seat outer ring close-fitting, the side of elasticity space ring combines with road structure.

Laterally screw is through well seat sidewall and elasticity space ring, and the quantity of screw and bolt is 3～16, and is distributed in well seat circumference side.

The thickness of elasticity space ring is 4～6mm.

The material of elasticity space ring adopts any in malthoid, rubber, the flexiplast.

The utility model compared with prior art its advantage is: have structure simple and direct, make that simple material is saved and advantage such as with low cost, it has remedied in the prior art buried type inspection shaft lid and often is difficult to accomplish and road surface maintenance level, and give the pedestrian, vehicle is made troubles or dangerous defects; Solve in the prior art inspection shaft lid and sunk but can't adjust, need bury defectives such as the waste construction cost is installed again.The utility model is applied widely, is applicable in inspection shaft, water grate or the ground case of urban operating mechanism such as different kinds of roads, square, greenery patches and various pipelines.

The utility model is further explained and explanation below in conjunction with drawings and Examples:

Description of drawings

Fig. 1 is the integrally-built vertical cut-away view of the utility model;

Fig. 2 is a vertical view of the present utility model.

The specific embodiment

As shown in Figure 1, adjustable inspection shaft lid, comprise that well lid 1 cooperation places on the interior shoulder 21 of well seat 2, well lid 1 is connected by the bolt 3 that is fixed with nut 31 is installed in the

longitudinal hole

12,22 with well seat 2, the upper port of the through hole 12 on the well lid 1 is provided with the interior shoulder 121 that bore matches with nut 31, and the inboard of well seat 2 is offered and cooperated the horizontal screw 4 that bolt 5 is installed.

Wherein the quantity of

longitudinal hole

12,22 and bolt 3 is 3～16, and is distributed on well lid 1 and the well seat 2.

Be provided with the screw thread 23 suitable in the through hole 22 on the interior shoulder 21 of well seat 2 with bolt 3.

Well lid 1 and well seat 2 adopts concrete and bar pouring to build up any in type, hard plastic moulding, the cast iron moulding.When well lid 1 and well seat 2 adopted concrete reinforcement structures or hard plastic, through hole 22 domestic demands were installed the cast iron sleeve pipe, again the cast iron internal surface of sleeve pipe be twisted into match with bolt 3 and screw thread 23; When well lid 1 and the 2 employing cast irons manufacturings of well seat, directly rub the screw thread 23 that matches with bolt 3 in the through hole 22.

The flexible space ring 6 of well seat 2 outer ring close-fittings, the side of elasticity space ring 6 combines with road structure.

Laterally screw 4 is through well seat 2 sidewalls and elasticity space ring 6, and the quantity of screw 4 and bolt 5 is 3～16, and is distributed in well seat 2 circumference sides.

The thickness of elasticity space ring 6 is 4～6mm.The one-tenth-value thickness 1/10 that is elasticity space ring 6 can be got 4mm or 6mm or 5mm or 4.5mm or 5.5mm, can also adopt the arbitrary thickness value between 4～6mm except that aforementioned list.

The material of elasticity space ring 6 adopts any in malthoid, rubber, the flexiplast.Elasticity space ring 6 of the present utility model be not limited to adopt malthoid, rubber, flexiplast etc. this in three; other has certain flexible material, and also all to can be used as space ring of the present utility model 6 used, and also all belong within the protection category of the present utility model.

Inspection shaft lid of the present utility model when mounted, earlier well seat 2 and lateral surface thereof being wrapped up in the elasticity space ring 6 that encloses imbeds in the lump, then bolt 5 is screwed in the screw 4, holding out against the road surface matrix with the top of bolt 5 is as the criterion, in again well lid 1 being lain on the shoulder 21, make on the well lid 1 plane equal, at last bolt 3 is screwed in the through

hole

12,22 with the road surface, and closely cooperate by bolt 3 internal thread 23 with through hole 22, withstand on the interior shoulder 121 of through hole 12 with nut 31 again and be as the criterion.

When inspection shaft lid of the present utility model overloads because of pressurized, or sink or during one-sided sinking because of other reason, can adjust in the following manner: earlier bolt 3 is back-outed, take out well lid 1, be screwed into bolt 3 (or with the bolt of other same specification replace also can) again, make bolt 3 withstand the ground of well seat 2 lower ends, continue to twist bolt 3 jack-up well seats 2 again, when reaching desired height, well seat 2 stops to twist bolt 3, pour into the cavity of well seat 2 bottoms then with deployed fast hardening concrete slurry, the bolt 3 of back-outing then, in the hole of bolt 3, also inject the position of fast hardening concrete again to well seat 2 bottom end faces, treat concrete setting after, lid is gone into well lid 1, to tighten in bolt 3 hand-holes again, to be considered as tight condition on the interior shoulder 121 of withstanding on of nut 31.
