Abstract
River tunnel shaft light cover plate is worn the present invention relates to one kind, the problem of security is poor in the prior art is mainly solved.The present invention wears river tunnel shaft light cover plate by using one kind, the cover plate includes lid, fixed structure, lock and handle, the lid uses the glass-reinforced plastic material of light-high-strength, the lid of the cover plate is fixed on shaft top by least three fixed structures, the fixed structure is provided with lock, the technical scheme provided with least one handle preferably solves above mentioned problem on the outside of lid, available in Chuan Jiang tunnels.
Description
Technical field
River tunnel shaft light cover plate is worn the present invention relates to one kind.
Background technology
Closely during the last ten years, China's oil-gas pipeline River Crossing engineering is more and more, the vertical shaft in Chuan Jiang tunnels is the key of tunneling, but vertical shaft cover plate is largely using Reinforced Concrete Materials (such as CN201310048636.9) at present, the huge cover plate dismounting of weight is difficult, several people are needed to operate simultaneously, made troubles to current check, more importantly oil-gas pipeline belongs to inflammable, explosive high-risk equipment, once there is leakage situation easily to catch fire, explosion accident, if now explosion wave breaks up concrete cover, cause a disconnected watt fragment to be scattered to hurt sb.'s feelings, this will bring very big potential safety hazard.Meanwhile, thick and heavy concrete cover does not have decompression function, once exploded in vertical shaft, it is impossible in very first time pressure release, mitigate damage sequence.
The present invention targetedly solves the problem.
The content of the invention
The technical problems to be solved by the invention are the problem of security are poor in the prior art new wears river tunnel shaft light cover plate there is provided a kind of.The cover plate is used in Chuan Jiang tunnels, with the preferable advantage of security.
To solve the above problems, the technical solution adopted by the present invention is as follows：One kind wears river tunnel shaft light cover plate, the cover plate includes lid, fixed structure, lock and handle, the lid uses the glass-reinforced plastic material of light-high-strength, the lid of the cover plate is fixed on shaft top by least three fixed structures, the fixed structure is provided with least one handle provided with lock, lid outside.
In above-mentioned technical proposal, it is preferable that the fixed structure is located at cover edge and shaft top edge junction.
In above-mentioned technical proposal, it is preferable that the lid is cylinder, fixed structure is evenly distributed on the outside of lid.
This patent proposes one kind and wears river tunnel shaft light cover plate, and material has lightweight, high-strength, exhausted combustion, is easy to cut, installs, usage cycles are long, the characteristics of from safeguarding.This patent will solve following technical problem：(1) substituting concrete cover realization prevents personnel from dropping, and meets flood season vertical shaft flood control rain-proof needs, it is ensured that tunnel safety.(2) when fire explosion occurs in tunnel or vertical shaft, if explosion wave destroys cover plate, because light cover plate material property can avoid producing personal injury.(3) when fire explosion occurs in tunnel or vertical shaft, light cover plate is let out first by jack-up and dissipates a large amount of gases and energy, so as to mitigate the blast pressure load that load-carrying members are subject to, achieves preferable technique effect.
Brief description of the drawings
Fig. 1 is the structural representation of cover plate of the present invention.
Fig. 2 is the top view of cover plate of the present invention.
In Fig. 1 and 2,1 is lid, and 2 be fixed structure, and 3 be lock, and 4 be handle, and 5 be vertical shaft.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Embodiment
【Embodiment 1】
As shown in Figure 1, one kind wears river tunnel shaft light cover plate, the cover plate includes lid, fixed structure, lock and handle, the lid uses the glass-reinforced plastic material of light-high-strength, the lid of the cover plate is fixed on shaft top by three fixed structures, the fixed structure is provided with lock, and lid outside is provided with two handles.The fixed structure is located at cover edge and shaft top edge junction.The lid is cylinder, and fixed structure is evenly distributed on the outside of lid.
When fire explosion occurs in tunnel or vertical shaft, light cover plate is let out first by jack-up and dissipates a large amount of gases and energy, so as to mitigate the blast pressure load that load-carrying members are subject to, if explosion wave destroys cover plate, because light cover plate material property can avoid producing personal injury.Cover plate is connected and is fixed by fixed structure with vertical shaft, while equipped with lock, locking prevents personnel's malfunction, the convenient movable cover plate if necessary of handle is easy to regular maintenance and management.
【Embodiment 2】
According to the condition and step described in embodiment 1, simply the lid of cover plate is fixed on the outside of shaft top, lid provided with four handles by 5 fixed structures.
Claims (3)
1. one kind wears river tunnel shaft light cover plate, the cover plate includes lid, fixed structure, lock and handle, the lid
Using the glass-reinforced plastic material of light-high-strength, the lid of the cover plate is fixed on shaft top by least three fixed structures,
The fixed structure is provided with least one handle provided with lock, lid outside.
2. river tunnel shaft light cover plate is worn according to claim 1, it is characterised in that the fixed structure is located at cover edge
At shaft top edge junction.
3. river tunnel shaft light cover plate is worn according to claim 1, it is characterised in that the lid is cylinder, fixed knot
