Abstract
The utility model relates to a kind of electricity well Antiexplosive manhole cover, including manhole cover body, manhole cover body is provided with some explosion-proof relief holes, and the top in explosion-proof relief hole is provided with steel mesh, and bottom is provided with resin sheet.Explosion-proof relief hole in the utility model, top sets steel mesh to be used to prevent rubbish from blocking, and bottom, which pours resin sheet, to be used to seal waterproof.Generation explosion time, the pressure of generation directly breaks through resin sheet, carries out pressure release through explosion-proof relief hole, moulding resin piece is poured again can repair well lid, reach the reuse of well lid, simple in construction, safe and reliable.
Description
Technical field
The present invention relates to manhole lid device, more particularly, to be a kind of electricity well Antiexplosive manhole cover.
Background technology
By accumulating for a long time in electricity well, naked light or Mars or generation are run into after fuel gas reaches demolition point
Blast, existing electricity well well lid is generally that cast iron or ordinary cement are prepared from, identical with common municipal well lid, and no correlation is explosion-proof to be set
Put, often popped up occurring explosion time well lid because pressure is excessive, greatly potential safety hazard is produced to periphery；If in well
Setting conventional vents are covered, then rainwater etc. can be entered in electricity well by ventilating opening, and destruction is produced to internal unit.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of explosion-proof well of electricity well simple in construction, safe and reliable
Lid.
To achieve the above object, technical solution of the invention is：A kind of electricity well Antiexplosive manhole cover, including well lid sheet
Body, manhole cover body is provided with some explosion-proof relief holes, and the top in explosion-proof relief hole is provided with steel mesh, and bottom is provided with resin sheet.
It is preferred that, the thickness of resin sheet is 1-1.5cm.
It is preferred that, include two explosion-proof relief holes.
It is preferred that, manhole cover body is poured by superhigh intensity RPC and formed.
It is preferred that, a steel wire hang is individually fixed in the borehole wall in the hook of manhole cover body lower surface, the two ends of steel wire rope.
It is preferred that, manhole cover body is provided with a theftproof lock.
It is preferred that, manhole cover body bottom is provided with a sealing ring.
By using above-mentioned technical scheme, the beneficial effects of the invention are as follows：The present invention sets some explosion-proof relief holes, on
Portion sets steel mesh to be used to prevent rubbish from blocking, and bottom, which pours resin sheet, to be used to seal waterproof；Generation explosion time, the pressure of generation is straight
Connect and break through resin sheet, carry out pressure release through explosion-proof relief hole, resin sheet is poured again can repair well lid, reach the weight of well lid
Use again, it is simple in construction, it is safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Main Reference Numerals explanation：（1st, manhole cover body；2nd, explosion-proof relief hole；3rd, steel mesh；4th, resin sheet；5th, link up with；6th, steel
Cord；7th, theftproof lock；8th, sealing ring）.
Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in figure 1, a kind of electricity well Antiexplosive manhole cover, including the manhole cover body 1 provided with theftproof lock 7, manhole cover body 1 is adopted
The arbitrary shapes such as squarely, circle are poured with superhigh intensity RPC, superhigh intensity refers to that strength grade exceedes
C100 concrete, without value is recycled, substantially reduces the stolen possibility of well lid.
When manhole cover body 1 is molded, reserved some explosion-proof relief holes 2 run through up and down preferably only reserve 2, it is ensured that well lid
The intensity of body 1.A steel mesh 3 is fixed in the top in explosion-proof relief hole 2 by welding manner, for preventing compared with ratchel and other rubbish
Rubbish, which drops, to be avoided blocking.The bottom of explosion-proof relief hole 2 has poured resin sheet 4, and the optimal thickness of resin sheet 4 is 1-1.5cm, for close
Seal waterproof.When occurring explosion time, the pressure of generation directly breaks through resin sheet, pressure release is carried out through explosion-proof relief hole, by pouring
Resin sheet can repair well lid, realize the reuse of Antiexplosive manhole cover, simple in construction, easy to use.
One steel wire rope 6 hangs on the hook 5 of the lower surface of manhole cover body 1, and the two ends of steel wire rope 6 are individually fixed in the borehole wall（Not
Show）.When blast pressure exceeds the pressure relief capability in explosion-proof relief hole, well lid can be popped up, and steel wire rope 6 then holds well lid, most
The ejection distance of the reduction well lid of limits, reduction is damaged to periphery.
To improve water resistance, a waterproof grommet 8 is provided between well lid and ground.
It is above-described, only presently preferred embodiments of the present invention, it is impossible to limit the scope that the present invention is implemented, it is every according to
Equivalent change and decoration that scope of the present invention patent is made, should all still fall within the range of the present invention covers.
