Description

Well lid with anti-settling and anti-theft feature

Technical field

The utility model relates to the used well lid of road construction, is specifically related to have the well lid of anti-settling and anti-theft feature.

Background technology

The pipeline, the route that are layed in below the road usually need repairing, safeguard or set up, so the well chamber need to be reserved in the highway section during road construction, and the relevant staff can enter the well chamber and construct the parts and the outdoor well lid of well is absolutely necessary like this.Using at present manhole cover structure is the well seat and the well lid that is arranged on the well seat that is embedded under the road surface, for the large road surface of load, such well lid is easy to be pressed by cart sunken, causes the road surface to produce uneven layer and falls, cause be full of cracks and the layer on peripheral road surface to fall, have potential safety hazard.Because well lid is mainly take rigid material as main at present, structure arranges simply, the stolen phenomenon of well lid often occurs at the city back warp.The big and small traffic accident that occurs because well lid is stolen also is to be unequal to its number, brings potential safety hazard for people's driving trip.If the well lid in main highway section, city is stolen, its consequence is hardly imaginable especially.

The utility model content

The utility model has overcome the deficiencies in the prior art, well lid with anti-settling and anti-theft feature is provided, it is inconsistent with peripheral roadbed subsidence to solve in the prior art well lid below sedimentation, and city Important Sections well lid is stolen easily, the defective of driving a vehicle and going on a journey and make troubles to people.

For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of well lid with anti-settling and anti-theft feature, comprise the anti-settling ring layer, be stuck in the well lid on the anti-settling ring layer, be fixedly connected with the concrete base layer of anti-settling ring layer one end, closely be connected to the flexible pavement of being combined with the anti-settling ring layer in concrete base layer top and edge and the borehole wall that is positioned at anti-settling ring layer below, described anti-settling ring layer is evenly distributed with four draw-in grooves on marginal portion that well lid is combined, be provided with two expansion strips in the described well lid, two expansion strip two ends sizes are corresponding with the draw-in groove size on the anti-settling ring layer, well lid, there is a segment distance on anti-settling ring layer and flexible pavement surface between described anti-settling ring layer and the borehole wall on the same level face.

Two above-mentioned expansion strip equal in length, mutual intersection and vertical in well lid.

Two above-mentioned expansion strips are elastic by fore shaft control.

Above-mentioned fore shaft is positioned at the center of well lid.

The above-mentioned used material of anti-settling ring layer is identical with concrete base layer.

An above-mentioned segment distance is 3cm-5cm.

The above-mentioned concrete base layer below road basal layer of combining closely, the road basal layer is positioned at the top of roadbed and closely connects.

The above-mentioned borehole wall is fixed on the vertical plane that concrete base layer, road basal layer and roadbed form.

Compared with prior art, the beneficial effects of the utility model are:

(1) the utility model is provided with the expansion strip of free-extension in the well lid that rigid material is made, control it by fore shaft and move, thereby well lid firmly can be locked on the anti-settling circle, when needs are opened well lid, the staff only need rotate with special-purpose key alignment fore shaft, get final product open manhole cover, enter the well chamber, do not have private key, just can't open manhole cover, easy to operate simple, can prevent effectively that also the lawless person from stealing the well lid of Important Sections, prevents unnecessary potential safety hazard.

(2) the utility model is provided with the anti-settling ring layer to well lid, anti-settling ring layer material therefor is identical with concrete base layer, so that the layer reduction of speed degree of well lid below is consistent with peripheral roadbed subsidence speed, thereby guarantee that well lid, anti-settling ring layer and flexible pavement surface are all the time on the same level face, reduce peripheral road surface and be full of cracks and layer probability that falls occur, guarantee the safety of people's trip.

Fig. 1 is the utility model structural representation;

Fig. 2 is that the utility model A is to view.

Reference numeral is expressed as respectively among the figure: 1, well lid; 2, flexible pavement; 3, anti-settling ring layer; 4, the borehole wall; 5, concrete base layer; 6, road basal layer; 7, roadbed; 8, fore shaft; 9, draw-in groove; 10, expansion strip.

The specific embodiment

Below in conjunction with attached Fig. 1 and 2 the utility model is further elaborated, the embodiment of this utility model is not limited to this.

Embodiment:

The utility model comprises anti-settling ring layer 3, be stuck in the well lid 1 on the anti-settling ring layer 3, be fixedly connected with the concrete base layer 5 of anti-settling ring layer 3 one ends, closely be connected to the flexible pavement 2 and the borehole wall 4 that is positioned at anti-settling ring layer 3 belows of concrete base layer 5 tops and edge and 3 combinations of anti-settling ring layer.Be evenly distributed with four draw-in grooves 9 on the anti-settling ring layer 3 of present embodiment and the marginal portion of well lid 1 combination, anti-settling ring layer 3 used materials are identical with concrete base layer 5.Be provided with two expansion strips 10 in the well lid 1 of present embodiment, two expansion strip 10 two ends sizes are corresponding with draw-in groove 9 sizes on the anti-settling ring layer 3, and two expansion strip 10 equal in length are in well lid 1 interior mutual intersection and vertical, fore shaft 8 controls are elastic, and fore shaft 8 is positioned at the center of well lid 1.There is a segment distance on the well lid 1 of present embodiment, anti-settling ring layer 3 and flexible pavement 2 surfaces between described anti-settling ring layer 3 and the borehole wall 4 on the same level face, distance is 3cm-5cm.Concrete base layer 5 belows of the present embodiment road basal layer 6 of combining closely, road basal layer 6 are positioned at the top of roadbed 7 and closely connect.The borehole wall 4 of present embodiment is fixed on the vertical plane that concrete base layer 5, road basal layer 6 and roadbed 7 form.

The course of work of the present utility model is as follows: because the raising of cost, the staff only needs to be provided with the place of well chamber in important traffic route, be provided with the certain thickness dustproof ring layer of falling of groove to the top of the borehole wall, then each port of the expansion strip on the well lid is aimed at corresponding groove, use the key turns fore shaft, each end points of expansion strip just snaps in the corresponding groove, fixes well head.When the staff need to enter the well chamber, only need to rotate fore shaft with special-purpose key, expansion strip leaves recess, and well lid is opened.

As above just can realize this utility model.
