Description

Technical Field

[0001] The present invention relates to the technical field of storage of pollutants and flushing water, and particularly relates to a side-line emergency poison storage pool for bridge drainage. Background Art

[0002] With the increasing attention to the protection of water environment quality and the enhancement of people's environmental protection awareness, the traditional drainage design concept of directly discharging bridge rainwater runoff into rivers has been challenged more and more.

[0003] In order to achieve the environmental protection goal of water environment sensitive waters, more and more drainage schemes for bridge drainage engineering design adopt the method of fully collecting the bridge deck rainwater runoff and setting environmental protection devices at the end of the pipeline.

[0004] In the prior art, the common poison storage pools are mostly on-line type, that is, the poison storage pool is arranged in the middle of the pipeline system. After rainfall, the runoff generated on the bridge deck first enters the poison storage pool, and then is connected to the existing drainage system or discharged into the water body.

[0005] However, since the pool body needs to be emptied after rainfall so as to be able to receive toxic wastewater in time in case of an accident, the on-line type poison storage pool often needs to be equipped with a relatively complex automatic control system, which brings great trouble to operation and management, and the poison storage pool has water inflow during each rainfall, greatly increasing the workload of maintenance and repair.

[0006] Therefore, how to realize that in normal operation, rainwater runoff is connected to the downstream pipeline system through the pipeline, and when pollutants leak, the pollutants and their flushing water are introduced into the poison storage pool, so as to reduce the environmental pollution risk of the water body and reduce the workload of management and maintenance of the poison storage pool has become an urgent technical problem to be solved by those skilled in the art.

[0036] Embodiment 1

[0037] As Figures 1 to 4 shown, a side-type emergency poison storage pool for bridge drainage includes a pool body connected to the drainage system of the bridge.

[0038] Among them, the pool body is an underground fully enclosed structure, located at the bottom of the bridge at the starting point of the bridge span, and includes a storage area and an inlet area;

[0039] A poison storage pool inlet gate 4 is provided between the storage area and the inlet area, and connection and isolation are achieved through the poison storage pool inlet gate 4;

[0040] The inlet area is connected to the drainage system of the bridge through a water inlet pipe 1, and the sewage to be stored is input through the water inlet pipe 1;

[0041] One side of the storage area is connected to the inlet area, and a sand collection tank 9 is provided at the bottom of the other side opposite to the side connected to the inlet area;

[0042] A branch pipe 2 is provided in the inlet area and is connected to the downstream drainage system through the branch pipe 2;

[0043] The branch pipe 2 is provided with a branch pipe gate 3 in a normally open state, and the opening and closing of the branch pipe 2 are controlled by the branch pipe gate 3;

[0044] The bottom elevation of the poison storage tank inlet gate 4 and the branch pipe gate 3 is the same as the bottom elevation of the water inlet pipe 1, and both are remotely controlled by the control center for opening and closing;

[0045] The control center can view the opening and closing states of the poison storage tank inlet gate 4 and the branch pipe gate 3 in real time;

[0046] When emergency poison storage is required, the poison storage tank inlet gate 4 is opened and the branch pipe gate 3 is closed.

[0047] The working principle of the present invention is as follows:

[0048] The control center of the present invention remotely controls the opening and closing of the poison storage tank inlet gate 4 and the branch pipe gate 3 to complete the switching of operating conditions.

[0049] The fact that the bottom elevations of the poison storage tank inlet gate 4 and the branch pipe gate 3 are the same as the bottom elevation of the water inlet pipe 1 can ensure smooth water inlet and outlet.

[0050] In practical applications, the present invention can be cleaned by introducing relatively clean runoff in the later stage of rainfall, without the need to separately set up a flushing chamber and configure corresponding flushing equipment.

[0051] In practical applications, when a chemical dangerous goods vehicle accident occurs on the bridge, the on-site personnel contact the control center as soon as possible through the emergency phone, and the control center can remotely control the branch pipe gate to close and open the poison storage tank inlet gate to prevent the chemical dangerous goods from polluting the water source.

[0052] The toxic and harmful substances accumulated in the present invention can be transported to the designated treatment point for treatment and disposal by a hazardous chemicals suction truck.

[0053] The invention is an underground fully enclosed structure, which is arranged at the bottom of the bridge at the starting point of the bridge span and is integrated with the greening landscape under the bridge.

[0054] The branch pipe gate 3 of the present invention is normally open at ordinary times. After the rainwater runoff on the bridge deck is collected by the pipeline and passes through the branch pipe 2 of the emergency poison storage tank under the bridge, it is directly discharged into the downstream drainage system, such as a river;

[0055] When a dangerous goods leakage accident occurs on the bridge deck, the branch pipe gate 3 leading to the river is remotely controlled to close, and the poison storage tank inlet gate 4 is opened to intercept and introduce the dangerous waste liquid into the present invention for storage, and the stored waste liquid is suctioned and transported out for treatment by a cleaning vehicle.

[0056] The present invention can be cleaned by introducing relatively clean runoff in the later stage of rainfall, without the need to separately set up a flushing chamber and configure corresponding flushing equipment.

[0057] In addition, the emergency poison storage pool can also operate according to the long-term reserved conditions. After the downstream sewage drainage system is further improved, the storage space of the emergency poison storage pool can be utilized, and drainage pumps can be added in the pool to realize the regulation of the initial rainwater on the bridge deck, and finally it is conveyed to the sewage treatment plant for treatment and then discharged.

[0058] In some embodiments, the bottom of the sand collecting tank 9 is located 0.5 to 0.8 meters below the bottom of the storage area, but the depth from the ground is more than 6 meters.

[0059] In practical applications, to ensure the pumping effect, the maximum depth of the bottom of the sand collecting tank 9 does not exceed 6 meters.

[0060] In some embodiments, the cross-section of the sand collecting tank 9 is trapezoidal, and the width corresponding to the opening position above is greater than the width corresponding to the bottom position.

[0061] In some embodiments, maintenance manholes 5 are provided at the tops of both the storage area and the water inlet area;

[0062] Each maintenance manhole 5 is provided with a maintenance cover plate.

[0063] In some embodiments, ladders 6 are provided on the side walls of the storage area and the water inlet area below the corresponding maintenance manholes 5.

[0064] In some embodiments, exhaust pipes 7 are provided at the top of the storage area;

[0065] Each exhaust pipe 7 is provided with an insect-proof cover, and the top end is about 50 cm above the ground, and the surrounding is blocked by greening.

[0066] In practical applications, ventilation pipes 7 with insect-proof covers are provided at the top of the present invention. The top of the ventilation pipe is about 50 cm above the ground, and the surrounding is blocked by greening, which can effectively prevent insects and rodents from entering and ensure smooth exhaust when the poison storage pool is filled with water.

[0067] In some embodiments, a fence 8 is provided at the top of the poison storage pool.

[0068] In practical applications, the upper part uses a fence 8 to enclose components such as the maintenance manhole 5, the ladder 6, the exhaust pipe 7 and the water inlet gate 4 of the poison storage pool at the top, and greening is carried out, which is integrated with the landscape under the bridge.

[0069] After the present invention is built, it is integrated into the landscape under the bridge, and only a small number of maintenance manholes 5, ventilation pipes 7 and gate hoists are exposed on the ground. To ensure safety, a fence 8 is set around the emergency poison storage pool.

[0070] In some embodiments, both the water inlet gate 4 of the poison storage pool and the branch pipe gate 3 are electric and manual dual-purpose gates, and the electric heads supporting the water inlet gate 4 of the poison storage pool and the branch pipe gate 3 are remotely controlled by the control center to achieve opening and closing.

[0071] In certain embodiments, the control center is a regional traffic control center and an on-site duty room on a bridge.

[0072] In some embodiments, obvious warning signs are set up along the bridge, and dedicated emergency telephones are set up.

[0073] In practical applications, in order to gain emergency response time, the present invention sets up obvious warning signs and emergency telephones along the bridge. When a chemical hazardous goods vehicle has an accident, the on-site personnel can contact the control center as soon as possible through the emergency telephone. The control center can then remotely close the branch pipe gate and open the water inlet gate 4 of the poison storage pool. The poison storage pool can then store water in an emergency to prevent chemical hazardous goods from polluting the water source.

[0074] Example 2

[0075] Take the super-large cross-river bridge in a provincial capital city in the south as an example. Under the bridge is a secondary water source protection area. Under normal circumstances, the rainwater runoff on the bridge deck is collected through pipes, connected to the underground drainage system by hanging pipes under the bridge, and then discharged directly into the river through the gravity flow of the drainage pipes below. In order to prevent the leakage of dangerous goods and adverse effects on the water body during the passage of dangerous goods transport vehicles on the bridge, a line-side emergency poison storage pool is set up at both ends of the bridge to regulate and store dangerous goods before transportation.

[0076] The emergency poison storage pool is a fully enclosed underground structure with a maintenance manhole on the top of the pool and a protective fence around it. The emergency poison storage pool is located in the green belt under the bridge and is fenced outside, covering an area of ​​about 120 square meters. Maintenance vehicles can enter the poison storage pool through the auxiliary road under the bridge. The minimum clearance under the bridge is not less than 3.5 meters, which meets the requirements for vehicle passage and post-accident cleaning vehicles to suck out dangerous goods.

[0077] The effective volume of a single emergency poison storage pool is about 100 cubic meters. The diameter of the branch pipe of the poison storage pool is DN1000, and the burial depth is about 2.0 meters. The water inlet gate of the poison storage pool adopts a 1.0m wide square gate, the net size of the water storage space is 7.0 meters × 6.3 meters, the effective water depth is 2.3 meters, and the super height is 70 centimeters. The main body of the poison storage pool is buried at a depth of about 3.3 meters, and the local sand collection trough is buried at a depth of about 3.8 meters. The gate of the emergency poison storage pool is unmanned and remotely controlled. In order to ensure the normal use of the equipment, it is necessary to strengthen inspections and maintenance at ordinary times.

[0078] Obvious warning signs and dedicated emergency telephones are set up along the bridge. When a vehicle carrying hazardous chemicals has an accident, the vehicle driver can contact the control center through the emergency telephone. The control center can then remotely close the emergency storage tank outlet gate and open the regulating storage tank gate to prevent hazardous chemicals from polluting the water source.

[0079] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
