Abstract
The utility model relates to a five-prevention manhole ring and a manhole cover, which are composed of a circular manhole cover and a manhole ring for supporting the manhole cover. The utility model is characterized in that a ring port slot for arranging a rubber ring is arranged in a ring port of the manhole ring, and an outer ring of the manhole ring is provided with at least three screw bolt holes fixed to a manhole body. At least three folding and supporting bases are evenly distributed at the lower part of the manhole ring along the circumference, and a guard manhole grating made of non-metal materials are supported on the supporting bases. Each of the folding and supporting bases is composed of supporting legs, supporting plates and connecting members, and the lower part of the ring port is provided with an anti-theft chain clamping hole. The utility model has five preventing functions of sound prevention, jump prevention, run prevention, theft prevention and crash prevention, and avoids generating accidents that pedestrians drop into manholes, and vehicles overturn. The utility model is suitable for various manholes of gas, water, heat and electricity.
Description
The utility model relates to a kind of inspection walling crib and well lid.
The present situation of existing various inspection walling crib and well lid (comprise combustion gas, water, heat, telecom conduit check walling crib and lid) is: model is lack of standardization, because of cracked, lose that to fall the accident that the people causes injury, disables continuous; Because the race of manhole, jumping, sound, displacement or manhole border sink, also often cause disturb residents, vehicle is overturned even cause traffic accident.
The purpose of this utility model provides a kind of anti-sound, anti-jump, anti-ly runs, five anti-walling crib and the well lids checked of antitheft, shatter-resistant, avoids the pedestrian to weigh down the accident that well, vehicle overturn and takes place.
The utility model five anti-technical schemes of walling crib and well lid of checking are: it is made up of the walling crib of round manhole cover and support well lid, it is characterized in that: leave the ring edge groove of placing rubber ring in the ring edge position of walling crib, the outer ring of walling crib is provided with at least three bolt holes of fixing with the well body, the walling crib bottom is evenly distributed to few three folding bearings along circumference, and the bearing upper support the anti-guide-well grate that nonmetals are made.
The door chain hole clipping is arranged at above-mentioned circle mouth bottom.
But above-mentioned folding bearing by clamping plate shape leg, be inserted in the middle of the leg and the support plate that rotates on the plane and penetrate leg and the connector of support plate is formed.
The utility model has the advantages that: the walling crib mouth stays ring edge groove in adopting, place the structure of rubber ring, increased well lid with in hold contacting of circle oral thermometer area, the area increasing coincide, thereby make manhole bring into play good firm, durable, pressure-bearing effect, stopped the phenomenon that well lid rings, jumps, runs; Below the manhole walling crib, be 120 ° of distribute three folding legs and support plates, support plate is opened, can lay two layers of anti-guide-well grate (glass fiber reinforced plastic material) of supporting making above, thereby after having avoided first floor well lid to break or losing, cause the pedestrian to weigh down the accident that well, vehicle overturn and take place.Owing to three support plate collapsible, therefore can not influence the work section of former manhole.For displacement and the sedimentation that prevents the manhole well head, in the manhole outer ring three solid points of bolt that are 120 ° of distributions are set, by the reserving hole of assembling manhole well head, reinstate the bolt rivet clasp with assembling manhole one.Can avoid rolling in the process of building the road the walling crib displacement that causes, increase manhole grinding compacting degree on every side, simultaneously, this assembling form can also be adjusted the walling crib setting height(from bottom) by pre-embedded bolt, fundamentally solves the problem of manhole border sedimentation.In addition, cruciate flower rib triangle decorative pattern is adopted on the well lid surface, can effectively play anti-skidding effect.Be applicable to well lids such as various coal gas, natural gas, tap water, heat, rainwater, sewage, telecommunications manhole cover or septic tank, collecting-tank, treatment tank.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is an a-quadrant enlarged drawing among Fig. 1;
Fig. 4 is the folding bearing schematic diagram of B-B section among Fig. 3.
As shown in Figure 1, 2, five anti-manhole covers are made up of the walling crib 1 of round manhole cover 11 and support well lid, leave the ring edge groove 2 of placing rubber ring in the ring edge position of walling crib 1, the outer ring of walling crib 1 is provided with three bolt holes of fixing with well body 34, walling crib 1 bottom is evenly distributed to few three folding bearings 5 along circumference, shown in Fig. 3,4, but folding bearing by clamping plate shape leg 8, be inserted in the middle of the leg and the support plate 9 that rotates on the plane and penetrate leg and the connector of support plate 10 is formed.Support plate 9 ends of folding bearing upwarp, and anti-guide-well grate wears 6 thereon, and fixing by wearing card 12.A circle mouthful bottom is provided with door chain hole clipping 7.
The well lid material adopts ductile iron, and walling crib adopts ductile iron or casting pig, and the well lid pressure-bearing is 380KN.Two layers of anti-guide-well grate adopt glass fiber reinforced plastic (FRP) material, pressure-bearing 1～1.2KN.Diameter: Φ 800mm～Φ 900mm.
