Abstract
The invention relates to a manhole with a piece of shock-absorption noise-reduction and fall-prevention plastic cushion net, belonging to the technical field of safety protection of public works manholes. The manhole comprises a manhole lid bracket, a manhole lid and a piece of fall-prevention net, wherein the fall-prevention net adopts a one-step injected and shaped concave structure, is placed on a positioning flange of the manhole lid bracket via a mounting flange or positioning clamping slots, and is fastened on the manhole lid bracket via inner hexagonal bolts; the manhole lid is placed on the fall-prevention net. The manhole provided by the invention adopts the structure that the fall-prevention net is additionally mounted between the manhole lid and the manhole lid bracket, and passersby and vehicles as well as large-size miscellaneous articles can be effectively prevented from falling into the manhole when the manhole lid is swept by rainwater or displaced; moreover, the fall-prevention net can play the roles of shock absorption, noise reduction and prolongation of service life of manhole lid. The mounting and overhaul are convenient, the manufacture cost is low, and the anti-theft effect is good. The manhole with the shock-absorption noise-reduction and fall-prevention plastic cushion net solves the problems that hard contact exists on a contact surface of the manhole, intense vibration and high-decibel noise are generated by the rolling and pressing of vehicles, no fall-prevention facilities are in the manhole, and passersby frequently fall into the manhole.
Description
Technical field
The present invention relates to a kind of inspection well head with damping, noise reduction, anti-fall plastic mattress net of applying in a kind of municipal engineering, belong to municipal engineering and check well head safety protection technique field.
Background technology
Along with China's urban construction fast development, the laying of network of underground is more and more, and the setting of the corresponding supporting manhole of the thing followed is also more and more.The traditional manhole using on urban pavement now is roughly divided into concrete prefabricated, three kinds of inspection well heads of plastics and cast iron, but no matter be what structure or the manhole of what material, the structure of its well lid is all the same, all to adopt seam that well lid is fixed on above well head, its contact surface is all hard contact, without any glissando, when such well lid is arranged on when being subject to vehicle on traffic major trunk roads and rolling, well lid and bearing seam are collided mutually, produce strenuous vibration and high-decibel noise, cause well lid and bearing to damage, cause the security incident that pedestrian or vehicle are fallen into, also affect people's life and city image simultaneously.On the other hand, because present extreme weather takes place frequently, torrential rain also often causes incity, city well lid washed away by rainwater or be shifted, and owing to there is no anti-falling facility in well head, pedestrian's falling accident occurs often, causes casualties.In order to address this problem, someone designed the inspection well head that nylon protective screening is installed below well lid, if application publication number is CN103485367A, notice of authorization number is CN203383235U, CN203383322U, CN203383241U, the invention of CN203440833 U and patent of invention, all to adopt hook and net to coordinate, the expansion bolt of band hook is fixed on and is checked on well head, again net is hung on hook, but because existing manhole mostly is concrete prefabricated, plastics and cast iron are made, do not match with nylon protective screening and hook, install very inconvenient, and rainwater when recoil protective screening with link up with between easily come off, and there is no damping, decrease of noise functions.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, provide a kind of inspection well head with damping, noise reduction, anti-fall plastic mattress net.This inspection well head is that plastic mattress net is arranged between well lid and well lid bearing, and be fixed by bolts to borehole wall surrounding, in the time that well lid is washed away by rainwater or is shifted, can effectively prevent pedestrian and vehicle pendant well and prevent that large volume foreign material from dropping in well, can also play the effect in application life of damping, noise reduction, prolongation well lid; And installation and repairing is convenient, and easy to manufacture, cost is low, good anti-theft effect.
The present invention realizes above-mentioned purpose by the following technical solutions:
This inspection well head with damping, noise reduction, anti-fall plastic mattress net is made up of well lid bearing, well lid and anti-drop net, it is characterized in that: anti-drop net is placed on well lid bearing, and well lid is placed on the top of anti-drop net; Described anti-drop net is concave structure, and by injection moulding one-shot forming, the top of anti-drop net is manufactured with mounting flange, is manufactured with locating groove below mounting flange, and the bottom of anti-drop net is manufactured with grid hole, on the net wall of anti-drop net, is manufactured with through hole; On described well lid bearing, be manufactured with locating flange, be manufactured with bolt hole on locating flange, the outer ring of well lid bearing is manufactured with fixing hole; Described well lid bottom is manufactured with reinforcing rib; Anti-drop net is placed in by mounting flange or locating groove on the locating flange of well lid bearing, and by the bolt hole on the through hole on anti-drop net net wall and well lid bearing to after good, by hexagon socket head cap screw, anti-drop net is fixed tightly on well lid bearing, again well lid is placed on well lid bearing, the mounting flange of anti-drop net is placed between well lid and well lid bearing.
The present invention's beneficial effect is compared with prior art:
This inspection well head with damping, noise reduction, anti-fall plastic mattress net adopts and fixedly add anti-drop net by special hexagon socket head cap screw between well lid and well lid bearing, in the time that well lid is washed away by rainwater or is shifted, can effectively prevent pedestrian and vehicle pendant well, also can prevent that large volume foreign material from dropping in well simultaneously.Anti-drop net adopts resilient plastics once injection moulding, can play the effect in application life of damping, noise reduction, prolongation well lid.Owing to adopting special hexagon socket head cap screw that anti-drop net is fixed, installation and repairing is convenient, and easy to manufacture, cost is low, good anti-theft effect.
