Abstract
The utility model relates to a road construction protective ring for inspecting a well. The annular protective ring of the utility model is a cast-iron back-buckling ring body. A lifting ring and at least one anti-flurring clamping device are arranged on the upper side of the ring body. The underside of the ring body is uneven, and has convexity and pit. The upper side of the ring body is provided with protected bolt holes. The cast-iron back-buckling annular protective ring has the characteristics of stabilization, safety, firmness and pressurization, which can prevent the problems of well mouth breaking, human falling, object falling, vehicle subversion, high labor intensity of construction, well cover blowing which is caused by impact, etc. The utility model can increase the efficiency of construction, and guarantees the construction quality of pavage. The utility model is the supporting facility for road construction, and is suitable for various gas, water, electricity and heating pipe inspection wells of road surface settings.
Description
The utility model relates to pave the way ancillary facility in the process of a kind of town road.
On existing urban infrastructure road, sedimentation is in various degree arranged all around all kinds of manhole covers.Its appearance has destroyed the planarization of road, and the time is long again, will form bigger hole bank around the manhole cover, causes the vehicular traffic severe jolt.The lighter has strengthened mechanical wearing and tearing, has reduced the application life of vehicle, and very person's vehicle is at once with regard to off-axis or overturn, and even causes the tragedy of car crash.Moreover the driver is all kinds of manholes hole bank on every side of dodging, and what cause a traffic accident also happens occasionally.Trace it to its cause is that existing manhole cover directly is sitting on concrete or the masonry walling crib, the circle mouth occurs broken well head easily, flies well lid, weighs down the people, weighs down the thing problem, before the pitch road work begins, at first all kinds of manholes on original road to be risen to certain elevation, the routine of paving the way is divided into the operation of two steps, for the first time be middle grain formula making elevation, be generally four centimeters; Rub the making elevation for the aggregate chips face for the second time, be generally two to three centimeters.When the depth displacement existence first time, when middle grain formula pitch is failed making again, the passing vehicle that travels causes the manhole base portion to be collided cracked and damage easily, when meeting the speed of a motor vehicle vehicle pass through faster, the moment that the car opinion contacts with walling crib can produce a hop segments, the impact force that produce this moment is an acceleration of gravity, and when this impact force of wheel by chance dropped on the manhole cover edge, well lid was often flown by pressure; In the making behind the grain formula bituminous concrete,, dig with bituminous concrete that pick little by little will be layered on original inspection walling crib mouth when for making surface layer aggregate chips rising manhole base or when laying cushion block.So, not only take a lot of work but also time-consuming, strengthened working strength of workers, wasted material, reduced work efficiency, prolonged the duration.
The purpose of this utility model provides a kind of manhole guard circle of building the road, and prevents the broken well head of road inspection well, flies well lid, weighs down the people, weighs down thing, problems such as labour intensity is big are overturned, constructed to vehicle.
The build the road technical scheme of guard circle of the utility model manhole: guard circle is an annular; it is characterized in that: the annular guard circle is a cast iron left-hand thread circle body; hoisting ring is set above the circle body Ka not with at least one anti-flying up; circle body bottom surface injustice; projection, pit are arranged, be provided with the protection bolt hole above the circle body.
Above-mentioned anti-flying up Ka evenly not be provided with three, is connected with circle body by bolt.
Above-mentioned hoisting ring is located in the groove above the circle body.
Be provided with the protection bolt hole above the above-mentioned circle body in the groove.
Above-mentioned circle body edge is up big and down small, is reverse frustoconic.
Advantage of the present utility model: cast iron left-hand thread annular guard circle, safe, firm, pressure-bearing prevent the broken well head of manhole, weigh down the people, weigh down thing, problems such as labour intensity is big are overturned, constructed to vehicle., anti-above the circle body fly up not Ka, prevent from that well lid is hit to fly up; The projection of circle body bottom surface or pit with well seat build-in, form firm integral body, well lid is stablized with guard circle, well seat cooperated, and the various roadbed subsidence common faults that manhole causes are thoroughly eradicated; And can improve construction efficiency, and guaranteeing the paving engineering quality, the ancillary facility of building the road that is absolutely necessary is applicable to all kinds of coal gas, water, electricity, pipe line manhole that road surface is provided with.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the shape schematic diagram in the utility model embodiment front;
Fig. 2 is the build the road schematic diagram of guard circle reverse side of Fig. 1 manhole.
Embodiment is shown in 1,2 figure, and the manhole guard circle of building the road is an annular, and its annular guard circle is nodular cast iron or cast steel left-hand thread circle body 1; Big on the circle body edge, little down, be convenient to grain formula bituminous concrete in the making, conveniently the left-hand thread circle is taken out; Above the circle body at interval 120 ° three anti-flying up be set do not block 2, be connected with circle body by bolt; Anti-flying up do not block 2, and circle body bottom surface injustice has projection 4 or pit 3; The hoisting ring of being located in the groove 5 is arranged above the circle body.Be provided with protection bolt hole 6 above the circle body in the groove.
Claims (5)
1, a kind of manhole guard circle of building the road is annular, and it is characterized in that: the annular guard circle is a cast iron left-hand thread circle body; hoisting ring is set above the circle body Ka not with at least one anti-flying up; circle body bottom surface injustice has projection, pit, is provided with the protection bolt hole above the circle body.
2, the manhole according to claim 1 guard circle of building the road is characterized in that: described anti-flying up Ka evenly not be provided with three, is connected with circle body by bolt.
