Abstract

The utility model discloses a road inspection well safety device, which belongs to technical field of road safety protecting devices, which comprises a cement cladding plate and an inspection well ring with an inspection well cover on the cement cladding plate, wherein the inspection well ring is communicated with the cave of the cement cladding plate to form a inspection well mouth, and an inspection well protective cover is arranged under the inspection well cover and in the inspection well mouth. The road inspection well safety device not only can prevent people from injury, vehicles from destroying, and electric cables from damage, because the well cover is stolen or damaged, but also has the advantages of low cost, simple operation and safety.

Description

The road cellar well safety device

Technical field

The utility model discloses a kind of road cellar well safety device, belong to the technical field of road safety protective device.

Background technology

Inspection shaft lid commonly used at present though replace original cast iron by cement, plastic-steel composite material, still has thicker reinforcing bar to make skeleton owing to inner, so still there is stolen phenomenon.People are covered stolen phenomenon in order to reduce inspection shaft as far as possible, have designed anti-theft type Safety manhole cover miscellaneous, but up to the present still can not thoroughly solve the stolen safety problem of bringing of inspection shaft lid.Because of the various reasons that may occur cause the inspection shaft losing of cover, in time do not built or when destroyed, people, car, broken well lid etc. all might occur and fall in the well and produce casualties, vehicle damage and light, the impaired phenomenon of cable.

The utility model content

The purpose of this utility model is to provide a kind of road cellar well safety device, that this road cellar well safety device not only can be avoided is stolen because of road cellar well lid, lose, produces casualties, vehicle damage and light, the impaired phenomenon of cable in the wells that fall such as lid, the people that may occur when destroyed, car, broken well lid, and cost is low, unmanned pilferage, simple to operate and safe and reliable.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of road cellar well safety device, comprise overlay on the cement, place on the cement on the overlay and have the inspection shaft circle of inspection shaft lid, the inner chamber of overlay communicates on inspection shaft circle and the cement, and form the inspection shaft mouth naturally, be provided with the inspection shaft safety cage in the below of inspection shaft lid, the inspection shaft mouth.

As a kind of preferred version of the present utility model, inspection shaft safety cage area of overlayable area and inspection shaft mouth under nature is close, and its shape can be a plane, also can be solid type.

As a kind of setting of above-mentioned preferred version, the mesh of inspection shaft safety cage is 3～10cm, and its braided material diameter is φ 1～5mm, and can bear the load that is not less than 120kg.

Further preferred as above-mentioned preferred version, inspection shaft safety cage are that one of the silk made by metal or natural fiber or synthetic fibers, line, rope weave and form.

After adopting said structure, not only can avoid stolen, lose, produce casualties, vehicle damage and light, the impaired phenomenon of cable in the wells that fall such as lid, the people that may occur when destroyed, car, broken well lid, and cost is low, unmanned pilferage, simple to operate and safe and reliable because of road cellar well lid.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

As shown in Figure 1, the utility model embodiment is the supporting inspection shaft safety cage of a kind of and round inspection shaft lid, and inspection shaft lid 3 is a composite material, and its diameter is a φ 700mm heavy type, and inspection shaft circle 4 internal diameters are φ 650mm.The flat shape of this inspection shaft safety cage 1 is circular, and its external diameter is φ 670mm, and grid is that 30*30mm is square, and its material therefor is that diameter is the nylon rope of φ 2mm.Selecting specification for use is the hard cement nail 5 of φ 4*65mm, and internal diameter is that φ 4mm, thickness are the pad 6 of 1mm.After hard cement nail 5 is inserted in pad 6, evenly distribute along inspection shaft circle 4 internal diameters and to hammer in the slit between the overlay 7 on inspection shaft circle 4 bases and the cement (or adjusting brick), pitch of nails is advisable with 5～20cm, then the rope of inspection shaft safety cage 1 periphery is wrapped in cement nail 5 heads (in the pad 6) 2～3 circles and gets final product.
