Abstract
The invention discloses a water-logging-proof system for an underground building. According to the water-logging-proof system for the underground building, a groove 2 is dug on the ground 1 of an entrance of the underground building, a waterproof wall 3 is arranged in the groove 2, a protection cover 4 is arranged on the upper portion of the groove 2, a lower opening of the groove 2 is communicated with a drainage system through filter screen meshes, and a sewer water inlet 5 is formed in front of the ground 1 of the entrance of the underground building. When heavy rain occurs, rainwater enters the drainage system from the sewer water inlet 5, water also enters the groove 2, the waterproof wall 3 rises due to buoyancy along with the increasing of the amount of water in a sewer, the upward buoyancy can overcome the resistance of a tension spring of the protection cover 4 so that the protection cover 4 above the waterproof wall can be opened through rotation along with a light rotary hinge, the waterproof wall also rises under the action of the buoyancy at the same time, and then the water blocking function is achieved. According to the water-logging-proof system for the underground building, the structure is simple, manual operation is not needed, and the waterproof wall can rise and fall automatically. The water-logging-proof system for the underground building is mainly used for solving the problem that underground buildings such as parking lots and underground stores can be submerged on rainy days and on stormy days.
Description
Technical field
The present invention relates to underground structure supporting facility, be specifically related to the anti-water-immersion system in a kind of underground structure.
Background technology
In recent years, along with urban development, the underground space is utilized gradually, increasing underground store, underground parking, underground warehouse occurs, original underground structure entrance drainaging scheme: in garage design, conventionally in track, playing slope place, to establish a gradient be 7.5%, exceed the slope of 300 millimeters of grades, and at highest point, first open drain of catchmenting is set, and then with 7.5% gradient slope aspect grade, in open drain, rainwater directly enters Storm Sewer Network, steel on adopting, is established in this open drain or cast iron double-edged fine-toothed comb is current in order to vehicle and people, but, because urban sewerage and drainage system is poor, once attacking the situation of city generation waterlogging, heavy rain happens occasionally, above-mentioned underground structure entrance only relies on the batter drainage method that exceeds 300 millimeters of grades to exist obviously not enough, especially severe be some basements usually to occur steeped in rainwater, may bring huge property loss to the people, even occur allowing above ground structure and life be in danger, so provide a kind of effective underground structure waterproofing system very necessary and important.
Summary of the invention
The invention provides the anti-water-immersion system in a kind of underground structure, solved existing underground structure by the problem of water logging.
Technical scheme of the present invention is: the anti-water-immersion system in underground structure; the 1 excavation groove 2 on entrance ground, underground structure; mine dam 3 is placed in groove 2; over cap 4 is arranged at groove 2 tops; lower openings is communicated with by filter screen aperture with drainage system, and 1 front portion, ground, building entrance arranges sewer water inlet 5 and forms.Specifically be configured to enter on entrance ground, underground structure 1 epistome and sewer water inlet 5 rear portions suitably apart from by underground structure throat width direction, one groove 2 being set, in groove 2, there is mine dam 3, mine dam shape front is rectangle, side is T-shaped, this mine dam is by there being the light material of some strength to make as rigid plastics, the over cap 4 of mine dam is arranged at groove 2 and mine dam 3 tops, over cap 4 can prevent that foreign material from entering and can freely open, its free unlatching can arrange the little very light pivot link formula loose-leaf of simple resistance and have the extension spring combination realization of replying pulling force, groove 2 bottoms are communicated with by filter screen aperture with sewer, sewer water inlet 5 adopts on open drain establishes steel or cast iron double-edged fine-toothed comb.The water that the present invention utilizes law of buoyancy allow and flows into drives mine dam 3 to rise, and stops the water of invasion, and simple in structure, easy to operate, automatic lifting is guarded without personnel.
Accompanying drawing explanation:
Fig. 1 is the structural representation that the anti-water-immersion system in underground structure of the present invention does not rise mine dam;
Fig. 2 is the structural representation that the anti-water-immersion system in underground structure of the present invention rises mine dam.
In figure, 1, ground, 2, groove, 3, mine dam, 4, over cap, 5, sewer water inlet.
The specific embodiment
The present invention is mainly by entrance ground, underground structure 1, groove 2, mine dam 3, over cap 4, and sewer water inlet 5 forms.The 1 excavation groove 2 on entrance ground, underground structure, mine dam 3 is placed in groove 2, and groove 2 tops have over cap 4 to prevent that other foreign material from entering, and lower openings is communicated with drainage system.In accompanying drawing 1, general sunny during without rain or light rain, mine dam 3 is placed in groove 2, over cap 4 under the effect of extension spring, is placed in groove 2 and mine dam 3 tops form vehicle walkway in closed condition, in accompanying drawing 2, during because of heavy rain heavy rain, first rainwater enters underdrainage system from sewer water inlet 5, and groove 2 water inlets, mine dam 3 utilizes buoyancy to rise with the water yield in sewer, the resistance that the floatage energy rising overcomes over cap 4 extension springs causes the over cap 4 on top to rotate and open with light pivot link loose-leaf, mine dam 3 also rises with buoyancy simultaneously, thereby performance dash effect, again can be with discharge reduction automatic descending, when rainwater reduces discharge reduction, mine dam 3 is because gravity automatic descending is under ground 1 time, over cap 4 under the restoring force effect of extension spring in level, mine dam 3 is returned to accompanying drawing 1 state.
