Problems with：
1. when heavy rain comes, wherein, underground pipe network is difficult to substantial amounts of flood of handling up immediately to rainwater, it is easy to trigger in city
Flood, the lives and properties for giving people cause damage.
2. when heavy rain comes, rainwater quickly flows away, and will not enter underground dirt bed, and dirt bed cannot attentively collect these
Moisture content.And 1 year most of the time did not had heavy rain, Urban Underground soil can be caused to be also impossible to moisture and to be supplemented.Can so cause
The long-term exsiccosis of " supply of city soil usual exclusion, the moisture content fallen when raining heavyly collect again less than ", appearance is dried up.Make
Obtain the trees water shortage on urban road and generate bad.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing one kind can improve urban path tree underground mud
The water storage structure of native water content.Its rainwater that can collect urban rainwater well, slowly permeates recharge of groundwater, plays irrigation city
The effect of city's afforestation vegetation, reduces municipal green area irrigation water consumption, and alleviate the discharge pressure of urban drainage pipe network.
The technical solution of the utility model is：The water storage structure of urban path tree underground soil water content can be improved, wrapped
Include and ooze cistern and overflow pipe；The cistern that oozes includes pond body upper cover and compound permeable formation；Pond body upper cover in upper end closed,
The container of lower ending opening, its inwall is provided with gap；Compound permeable formation is located at pond body upper cover lower ending opening, its with pond body on
Formed between cover can accommodate rainwater ooze storage chamber；The adjacent gap for oozing cistern is connected by overflow pipe.
The further technical scheme of the utility model is：It also includes catch-basin and connecting pipe；Set on the wall of catch-basin side
There is delivery port；The inwall of pond body upper cover is provided with water inlet；Pass through between the delivery port of catch-basin and the water inlet of pond body upper cover
Connecting pipe is connected.
Further technical scheme is the utility model：Compound permeable formation includes rubble layer, coarse sand successively from the inside to the outside
Layer and permeable loam layer；Rubble layer is located at and oozes in storage chamber, and permeable loam layer is contacted with natural soils.
The utility model further technical scheme is：It also includes osmos tube；Osmos tube open upper end is oozing retaining
In chamber, natural soils are inserted in lower end through compound permeable formation is oozed, and its lower end tube wall is provided with permeability hole.
Further technical scheme is the utility model：The top of pond body upper cover is in the arched top of evagination, and its lower end is opened
It is provided with mouthful to oozing the pond toe board that stretches out of storage chamber outside.
The utility model has the following advantages that compared with prior art：
1st, have concurrently ooze, water storage function, the rainwater in urban rainwater well being collected by oozing cistern, rainwater storage oozing storage
In water cavity, recharge of groundwater is slowly permeated through compound permeable formation, under ooze rainwater and be available for trade trees to absorb, without using municipal administration
Water resource is irrigated.Reduce municipal green area irrigation water consumption.
2nd, share and alleviate the discharge pressure of urban drainage pipe network, when heavy rain is met with, a part of rainwater in catch-basin
Cistern can be entered to infiltrate by connecting pipe oozes storage chamber, plays abatement rainwash, reduces urban waterlogging Probability
Effect.
3rd, ooze cistern to be arranged on below earth's surface, drainage grade can be adjusted below earth's surface, so as to make full use of people
The underground space on trade, the use function on pavement is not influenceed.
4th, oozing cistern can be intermittently-arranged below pavement, and the adjacent gap for oozing cistern is connected by overflow pipe
Logical, quantity is more, and water-holding capacity is strong.
The utility model is further described below in conjunction with figure and embodiment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional views of Fig. 1.
Specific embodiment
Embodiment 1：
As shown in Figure 1-2, the water storage structure of urban path tree underground soil water content can be improved, including ooze cistern,
Overflow pipe 3, catch-basin 5, connecting pipe 6 and osmos tube 7.
The cistern that oozes includes pond body upper cover 1 and compound permeable formation.Pond body upper cover 1 is in upper end closed, lower ending opening
Container, its inwall is provided with gap 11 and water inlet 12.The top of pond body upper cover 1 is in the arched top of evagination, its lower ending opening
Place be provided with a ring, to oozing the pond toe board 13 that the outside of storage chamber 4 is stretched out.Compound permeable formation is located at the lower ending opening of pond body upper cover 1
Place, its formed between pond body upper cover can accommodate rainwater ooze storage chamber 4.The adjacent gap 11 for oozing cistern passes through overflow pipe
Road 3 is connected.Compound permeable formation includes rubble layer 21, coarse sands layer 22 and permeable loam layer 23 successively from the inside to the outside.21, rubble layer
