When burning line is leaked in combustion gas pipe trench, its combustable gas concentration reaches explosion limit and explodes, when
When blast impulse wave pressure rises rapidly and reaches the maximum of venting of dust explosion plate and bear pressure, venting of dust explosion plate is destroyed, now combustion gas pipe trench
Interior pressure can occur pressure release from destroyed open-mouth, so as to reduce brisance.If in addition, being stored in rainwater storage cabin rainy
Water, after venting of dust explosion plate is destroyed, rainwater enters combustion gas pipe trench by open, and it has buffering energy-absorbing effect to explosion wave.By
Above-mentioned reaction, the power for producing of exploding will be greatly reduced, and effectively reduce the damage of the building on integrated pipe cabin and ground
Evil.When blast terminates, scene after calamity is processed for convenience, the water in combustion gas pipe trench need to be drained, under controlling the gate first
Drop, opening is closed, and then controls suction pump to start to draw water, and water enters rainwater storage cabin by aqueduct.When in combustion gas pipe trench
After water is drained, professional can carry out maintenance process into the scene of the accident.
Preferably, the area of section of the combustion gas pipe trench is smaller with integrated pipe cabin compared to rainwater storage cabin.
Preferably, the combustion gas pipe trench is assembled by prefabricated high strength anti-explosion armoured concrete slab.
Preferably, design grade control alluvial problem in the rainwater storage cabin.
Preferably, the venting of dust explosion plate uses lightweight fragile material, in block and powder when being destroyed by shock
Last shape, is difficult to form secondary injury in pressure release.
Preferably, the water proof rubber circle is water swelling rubber ring, and every block of venting of dust explosion plate sets twice water proof rubber circle
To meet waterproof requirement of the combustion gas pipe trench in rainwater storage cabin.
Preferably, in the rainwater storage cabin of the aqueduct has back bending.
Compared with prior art, its remarkable advantage is the present invention：（1）The unusual peace in view of burning line of traditional piping lane
Without burning line included into piping lane, the present invention solves burning line and enters the safety of corridor and asks full sex chromosome mosaicism to a certain extent
Topic.（2）Add the theory that rainwater storage cabin meets sponge city.（3）Combustion gas pipe trench area of section is smaller, if it is quick-fried that combustion gas occurs
Fried, its blast magnitude also can be accordingly smaller（4）Venting of dust explosion plate is applied on combustion gas pipe trench, explosion time occurs will effectively be let out
Pressure, reduces brisance.（5）Water in Adjusting rainwater cabin has energy-absorbing effect to blast, can effectively reduce brisance.（6）
