Adopt the utility model discloses a combination is held the drainage mode and need not to enlarge on a large scale the cistern capacity, can reduce safe risk to a certain extent, practices thrift engineering cost, reduction expropriation of land scope can be shown, a large amount of arable lands is being practiced thrift to can avoid to a certain extent with local villager entanglement, maintain social stability, economic loss is reduced in ponding alluviation farmland in the time of can effectively avoiding the cistern to collapse, has apparent economic benefits, fully consider the environmental protection measure, avoided the pollution to local environment, drinking water source.

Description

A kind of storm seepage system

Technical field

This utility model belongs to a kind of storm seepage system.

Background technology

The continuous complications of mountainous area highway, road catchment area is big, and rainfall is big and more concentrates, and needs short time Nei Jiang road Area water is discharged in order to avoid affecting road safety.At present in Collapsible Loess District, because of draining lack of space, often through in road Nearby build cistern and road hydrops are introduced into natural evaporation in pond by rhone.For this drainage mode, have three Individual problem, one to be that cistern antiseep, tension split measure less, there is larger hidden leakage defect；Two is that reservoir capacity is less not Continuous rainfall charge for remittance functional requirement can be met, rainwater overflow top easily cause the cistern periphery soil body to cave in, slippery；Three is to increase water-retention Tankage can increase potential safety hazard it is difficult to ensure masses' security of the lives and property.

Utility model content

The purpose of this utility model is to provide a kind of environmental protection, economic, practical storm seepage system.

For achieving the above object, the technical solution adopted in the utility model is：A kind of storm seepage system, including cistern With filter well, in cistern, it is provided with overflow wall, cistern is partitioned into left cistern, right cistern two parts by overflow wall； Filter well is arranged on the bottom of right cistern, filter well side wall is provided with seepage well mouth, the height of seepage well mouth is higher than right cistern Bottom and less than overflow wall height.

Preferably：The top of described filter well is reinforced concrete core-tube, bottom is gravel-pack, bottom is mixed for reinforcing bar Solidifying soil shaft bottom.

Preferably：Described seepage well mouth is connected with gravel-pack by overflow pipe.

Workflow of the present utility model is as follows：(1) rainwater is transported to left cistern, and overflow wall makes hydrops be sunk first Form sediment, debris and pollutant can be filtered out to a certain extent, if the water level that finally confluxes is not less than overflow wall, right cistern and infiltration Well is only used as safety stock, does not now play effect；(2) when the water level of left cistern is higher than overflow wall, rainwater enters right water-retention Pond, rainwater carries out secondary precipitation, and when the water level of right cistern is less than seepage well mouth, filter well equally as safety stock, does not play Effect；(3), when right water-retention pool water level is higher than seepage well open height, hydrops pass through overflow pipe entrance filter well, and hydrops are along untreated The powder soil horizon borehole wall permeates to surrounding soil discharges；The self purification of powder soil horizon can reduce pollutant further and is directly entered ground simultaneously Lower water, has good environmental-protection function.This utility model only needs the mud of periodic cleaning cistern at the bottom of pond, dirt, impurity Meet the requirement of environmental protection.

The function of overflow pipe is as follows：1. avoid current dirty along the infiltration borehole wall, cause collapsible loess damaged or destroyed by flood；2. weaken water Stream hits, to infiltration bottom, the effect of splashing.

This utility model produce beneficial effect be：(1) need not be advised greatly using combination drainage mode of the present utility model Mould expands reservoir capacity, can reduce security risk to a certain extent, saves construction costs；(2) expropriation of land scope can be substantially reduced, Save substantial amounts of arable land, and can avoid to a certain extent and local villager's entanglement, maintain social stability；(3) can be prevented effectively from Hydrops alluviation farmland when cistern collapses, reduces economic loss, has significant economic benefit；(4) take into full account environmental conservation Measure, it is to avoid pollution to local environment, drinking water source.

Brief description

Fig. 1 is the structural representation of embodiment 1.

Specific embodiment

With reference to specific embodiment, the utility model is described in further detail, but protection domain of the present utility model does not limit In this.

Embodiment 1

As shown in figure 1, a kind of storm seepage system, including cistern and filter well 9, in cistern, it is provided with overflow wall 3, Cistern is partitioned into left cistern 1, right cistern 2 two parts by overflow wall 3；Filter well 9 is arranged on the bottom of right cistern 2 Portion, filter well 9 side wall is provided with seepage well mouth 4, and the height of seepage well mouth 4 is higher than the bottom of right cistern 2 and is less than overflow wall 3 Highly.The top of described filter well 9 is reinforced concrete core-tube 5（Highly it is not less than yellow soil horizon of collapsibility thickness）, bottom be gravel Stone packed layer 7, bottom are armored concrete shaft bottom 8（15cm thickness high-performance abrasion-resisting concreting forms）.Described seepage well mouth 4 By overflow pipe 6（PPR pipe）Connect with gravel-pack 7.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
