Abstract
The utility model discloses a ground well sealing device, which comprises a well cover and a seat, wherein a filling material composed of inorganic gelling material and sand is arranged between the middle of a high strength fiber cloth. In order to increase strength, the filling material is filled in the multilayer high strength fiber cloth. Because the well cover and the seat are not made by cast iron or concrete iron cement, but by the filling material which is composed of inorganic gelling material and sand, thereby thieves can not steal the well cover and the seat. The device is made by non-metal materials, so the weight is light, the strength of the material is high, and the vehicles can not damage the device, thereby avoiding accidents. The utility model has the advantages of simple technology and low cost.
Description
Technical field
The utility model belongs to the infrastructure of building class, specifically a kind of used ground well closing device when being used under the ground wells such as inspection, installation, maintenance facility.
Background technology
Existing ground well closing device comprises ground well lid and well seat, mostly is entirely and cylinder iron makes, or cylinder iron do the well seat, makes lid with reinforced concrete.Casting iron well lid is often stolen by the lawless person, the lid of reinforced concrete can produce arrisdefect because of the weight that will bear vehicle etc. on the road surface again, slight crack occurs exposes reinforcing bar, ground well lid or ground well lid breakage appear not having through regular meeting, careless or the walking at night of people falls into ground well, causes the personal injury incident to happen occasionally; And cast iron well seat and lid, cost is higher relatively.
The utility model content
For antitheft, anti-tamper, avoid personal injury can reduce cost again simultaneously, the technical solution of the utility model is: the ground well closing device comprises ground well lid and well seat, and well lid and seat are the inserts at useful inorganic coagulation material of the therebetween of high strength fibre cloth and sand mix.
In order to gain in strength, can be between the multilaminar high strength cloth that is arranged above and below, to be covered with inserts.
Since well lid and seat not cylinder iron or reinforced concrete make, be inserts, so the lawless person can not go to steal at useful inorganic coagulation material of the therebetween of high strength fibre cloth and sand mix; This kind product weight is light, and the intensity height can not damaged by pressure by vehicle, thereby can avoid the generation of accident, and this product manufacture is simple, low cost of manufacture.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a sectional view of the present utility model.
The specific embodiment
Among Fig. 1, the ground well closing device comprises well lid 1 and seat 2, at the useful inorganic coagulation material of therebetween of high strength fibre cloth 3 and the inserts 4 of sand mix up and down.In order to increase its intensity, high strength fibre cloth 3 can be the multilayer that distributes up and down, and interlayer is covered with inserts 4, for further gaining in strength, also can be in inserts 4 the mix high fiber strength strains.
Claims (2)
1, a kind of ground well closing device comprises well lid (1) and seat (2), it is characterized in that: well lid (1) and seat (2) are at the useful inorganic coagulation material of therebetween of high strength fibre cloth (3) and the inserts (4) of sand mix.
2, ground as claimed in claim 1 well lid is characterized in that: high strength fibre cloth (3) can be the multilayer that distributes up and down, and interlayer is covered with inserts (4).
