Abstract
The present invention relates to a kind of inspection well head with damping, noise reduction, anti-fall plastic mattress net, belong to municipal engineering and check well head technical field of safety protection.It is made up of well lid bearing, well lid and anti-drop net, and anti-drop net is the concave structure of single injection-molded, and be placed on the locating flange of well lid bearing by mounting flange or locating groove, be fixed tightly on well lid bearing by hexagon socket head cap screw, well lid is placed on anti-drop net.The present invention adopts installs the structure of anti-drop net additional between well lid and well lid bearing, when well lid to be washed away by rainwater or is shifted, effectively can prevent pedestrian and vehicle pendant well, also can prevent large volume foreign material from dropping in well simultaneously; Anti-drop net can also play the effect in damping, noise reduction, prolongation well lid application life.And installation and repairing is convenient, cost is low, good anti-theft effect.Solving existing inspection well head contact surface is all hard contact, produces strenuous vibration and high-decibel noise, and do not have anti-falling facility in well head when vehicle rolls, and the problem of pedestrian's falling accident often occurs.
Description
Technical field
The present invention relates to a kind of inspection well head with damping, noise reduction, anti-fall plastic mattress net applied in a kind of municipal engineering, belong to municipal engineering and check well head technical field of safety protection.
Background technology
Along with China's urban construction fast development, the laying of network of underground gets more and more, and the setting of the corresponding supporting manhole of the thing followed also gets more and more.Traditional manhole that present urban pavement uses is roughly divided into concrete prefabricated, plastics and three kinds, cast iron check well head, but be no matter the manhole of what structure or what material, the structure of its well lid is all the same, all adopt seam to be fixed on above well head by well lid, its contact surface is all hard contact, without any glissando, when such well lid be arranged on traffic major trunk roads are subject to vehicle roll time, well lid and bearing seam are collided mutually, produce strenuous vibration and high-decibel noise, well lid and bearing is caused to damage, the security incident that initiation 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 not having anti-falling facility in well head, often pedestrian's falling accident occurs, causes casualties.In order to address this problem, someone designed the inspection well head installing nylon protective screening below well lid, if application publication number is CN103485367A, Authorization Notice No. is CN203383235U, CN203383322U, CN203383241U, the invention of CN203440833U and patent of invention, all adopt hook and net to coordinate, being fixed on by the expansion bolt of band hook checks 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 easily come off between protective screening and hook during rainwater recoil, 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 arranged between well lid and well lid bearing by plastic mattress net, and be fixed by bolts to borehole wall surrounding, when well lid to be washed away by rainwater or is shifted, effectively can prevent pedestrian and vehicle pendant well and prevent large volume foreign material from dropping in well, the effect in damping, noise reduction, prolongation well lid application life can also be played; And installation and repairing is convenient, easy to manufacture, cost is low, good anti-theft effect.
The present invention realizes above-mentioned purpose by the following technical solutions:
The inspection well head of this band 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, and the net wall of anti-drop net is manufactured with through hole; Described well lid bearing is manufactured with locating flange, locating flange is manufactured with bolt hole, the outer ring of well lid bearing is manufactured with fixing hole; Reinforcing rib is manufactured with bottom described well lid; Anti-drop net is placed on the locating flange of well lid bearing by mounting flange or locating groove, and by the through hole on anti-drop net net wall and the bolt hole on 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:
The inspection well head of this band 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, when well lid to be washed away by rainwater or is shifted, effectively can prevent pedestrian and vehicle pendant well, also can prevent large volume foreign material from dropping in well simultaneously.Anti-drop net adopts resilient plastics once injection moulding, can play the effect in damping, noise reduction, prolongation well lid application life.Owing to adopting special hexagon socket head cap screw to be fixed by anti-drop net, installation and repairing is convenient, and easy to manufacture, cost is low, good anti-theft effect.
