Abstract

The utility model relates to an anti-theft sealing well tool collocated in the electric power, communication or government water supply and drainage well. The anti-theft sealing well tool is composed of a well cover [1] and a well ring [2] which is fixedly arranged on a well mouth. The well cover [1] is composed of a glass fibre coating layer[8], a stone pouring packed layer [5], a metal framework [9], a metal net [6] and a glass fibre cloth reinforcing layer [7]. A non-through hole type handle or a groove used for lifting is arranged on the well cover [1]. The well ring [2] is equipped with a sealing ring [3]. The anti-theft sealing well tool solves the present problems that the sealing performance of the present well tool is poor, the rain can easily get into the well, and the present well tool can be easily stolen to cause people being injured. The anti-theft sealing well tool is mainly used in the seal covers of electric power cable wells, or communication cable wells and government water supply and drainage wells on road surface.

Description

Anti-theft sealing well tool

Technical field

The utility model relates to a kind of urban operating mechanism, particularly a kind of anti-theft sealing well tool that is used for capping ground place electric power and communication cable well and municipally descends municipal engineering vertical shaft such as well.

Background technology

At present, electric power, the communication cable well that generally uses in municipal administration or the sub-district and municipally descend the well tool of well, mostly form by a casting iron well lid and the walling crib that is fixed on the well head place, its walling crib is generally common annular cast iron walling crib, and well lid is provided with one or two small through hole, be used for well head is opened in its pull-up, to electric power, communication cable or go up water with water valve and sewer pipe carry out maintenance and inspection from the beginning.Because described well lid and walling crib are made by cast iron, behind both mutual buckle closures, lack sealing, be easy to enter rainwater in the well, and waste gas also is easy to be discharged in the air from the small through hole of well lid or peripheral slit in the well, and the casting iron well lid that can move often also can become the robber and steal optimum target in order to exchange money.Therefore, its weak point is that sealing is relatively poor, and outside rainwater is easy to enter in the well, in the well waste gas also the row of being easy in air, and be easy to be stolen by the robber, pedestrian and vehicle are constituted certain danger, safety and reliability are poor.

Summary of the invention

The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of good airproof performance is provided, and can not stolen safe and reliable anti-theft sealing well tool by the robber.

In order to achieve the above object, the solution that the utility model is taked is, it is made up of well lid and the walling crib that is fixedly installed on the well head place, described well lid buckle closure is on described walling crib, be characterized in, described well lid is made up of the resin gel coating resin on substrate and surface disposed thereon, described substrate is by the glass fiber clad, building stones cast packed layer, metallic framework, wire lath and glass fabric enhancement Layer constitute, described metallic framework, wire lath and building stones cast packed layer all are closed among the glass fabric enhancement Layer of described glass fiber clad and described base plate bottom, the cast of described building stones cast packed layer is cemented in the gap of described metallic framework, described wire lath is laid on described glass fabric enhancement Layer and building stones cast packed layer, between the metallic framework, described resin gel coating resin is cemented in the upper surface place of described glass fiber clad, and described walling crib is provided with sealing ring.The well lid that nonmetals are made, even it is easy to move again, and for the thief, become can not be used to sell for money, robber and unhelpful common cover, thereby make the theft well lid thoroughly lose meaning, antitheft purpose just is easy to realize.The setting of sealing ring improves its sealing greatly.

In order to ensure its sealing, press tightlyer when making on the well lid buckle closure, the flexible seal ring that described sealing ring is preferably made by rubber, silica gel or soft plastics.Certain above-mentioned sealing ring also can be made by other waterproofing materials, no longer describes in detail herein.

For the ease of its well lid is mentioned, in order to valve or electric wire etc. in the inspection-pit, no matter whether its sealing ring is made by rubber, silica gel or soft plastics etc., described well lid is provided with and is used for its handle of mentioning or mentions groove, described handle is a metal parts of making integrative-structure with described metallic framework, on described well lid, be positioned at the position of described handle bottom and periphery, be provided with the pit that is used for the described handle of catching.It is above-mentioned handle or to mention groove be that the well lid of non through hole formula is mentioned parts.Above-mentioned handle or the quantity of mentioning groove are at least 1, and is limited a plurality of as 1,2,3 etc.Pit below the handle of non through hole formula or mention the setting of groove makes it both be easy to be raised, and rainwater is flowed in the well.

In order further to improve its sealing, prevent that more effectively rainwater from entering in the well, no matter whether described sealing ring is made by materials such as rubber, silica gel or soft plastics, also no matter whether be provided with handle or mention groove on its well lid, the outer edge that is preferably in described well lid is provided with the ring packing edge of downward protrusion, and the internal face on described ring packing edge is close to the outside wall surface place of described walling crib.

Because the utility model adopted said structure, non-cast iron materials well lid with and the employing of clad type structure, make theft well lid person helplessly lose the channel that well lid is sold for money, thereby make manhole cover anti-theft be easy to realize; The setting up of sealing ring on the walling crib increases the sealing of well lid buckle closure greatly, and rainwater is difficult for entering in the well; The setting on ring packing edge on the well lid has further improved its sealing, and therefore, the utlity model has antitheft, good airproof performance, be easy to lift, and safe in utilization, convenient, advantage reliably, and can effectively save iron and steel resource.
