Abstract
The utility model discloses a slab culvert sewage intercepting well, which comprises a slab culvert body and a sewage intercepting well. The sewage intercepting well comprises a first sewage intercepting cavity communicated with a water inlet and a second sewage intercepting cavity communicated with a river channel. A flap valve is disposed between the first sewage intercepting cavity and the second sewage intercepting cavity. An intercepting pipe is communicated with the first sewage intercepting cavity. Grating is arranged between the intercepting pipe and the first sewage intercepting cavity through a grating guide groove. After being intercepted by the grating, first rain and drought flow sewage transferred by a slab culvert is collected by the slab culvert sewage intercepting well and transferred to a sewage plant for treatment. Excess later-stage rainwater of rainstorm can be discharged to the river channel through the flap valve. Therefore, the slab culvert sewage intercepting well can effectively reduce first rain pollution to the river channel and ensure that the river channel collects water under normal circumstances, is flexible in arrangement, stable in flow, free of blocking and convenient in operation and management, and has less devices.
Description
Technical field
The utility model relates to the water discharge technology field, relates in particular to a kind of slab culvert and cuts dirty well.
Background technology
Because the development of industrial economy and the discharging of people's daily life waste water, the river course in a lot of cities is by severe contamination.Because most of river courses have functions such as city flood control, view concurrently, therefore when handling the Drain contamination for river channel problem, to take into account interests in many ways, be difficult to the perfect solution that finds to take into account each side.
Contaminated in order to prevent the river course, just need to collect early-stage rainwater and sewage.Common technological means is that rainwater and sewage carry out sewage and dams before the river course discharging in the early stage; But transfer because the part municipal sewage system adopts slab culvert to carry out sewage, the slab culvert size is bigger, and normal method is difficult to transform and dams; Rainy day is easy to generate overflow, makes the river course receive severe contamination.
Therefore, those skilled in the art is devoted to develop a kind of convenience, energy-conservation slab culvert catchpit, improves the effect of damming greatly, and the sewage that will dam is introduced Wastewater Treatment Plant, prevents the pollution of river.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of convenience, energy-conservation slab culvert cuts dirty well.
For realizing above-mentioned purpose, the utility model provides a kind of slab culvert to cut dirty well, comprises the slab culvert body and cuts dirty well; Said section dirty well comprises first section dirty chamber that connects with water inlet and the second section dirty chamber that connects with the river course; Be provided with flap valve between said first section dirty chamber and the said second section dirty chamber; One holds back pipe is communicated with said first section dirty chamber, and said holding back between pipe and the said first section dirty chamber is provided with grid through the grid guide groove.
Preferably, said flap valve is provided with the rope that lifts that is used for forced discharge.
Preferably, said flap valve is the lower resistance composite material.
Preferably, said grid is a composite material.
The beneficial effect of the utility model is:
The slab culvert of the utility model cuts dirty well, and first rain that slab culvert is carried and dry flow sewage are collected through grid interception back and delivered to the Sewage Plant processing, and excessive later stage rainwater can be disposed to the river course through flap valve during heavy rain; Alleviated of the pollution of first rain effectively to the river course; Can guarantee that the river course receives water under normal condition, the few and stability of flow of equipment is set flexibly; Can not stop up, operational management is convenient.
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.

Fig. 2 is an A-A broken section structural representation among Fig. 1.
Fig. 3 is a B-B broken section structural representation among Fig. 1.
Fig. 4 be among Fig. 2 C to the broken section structural representation.
Fig. 5 is the plane structure sketch map of grid among Fig. 2.
The specific embodiment
Like Fig. 1, shown in Figure 2, the slab culvert of the utility model cuts dirty well, mainly comprises slab culvert body 1 and cuts dirty well.Cut dirty well and comprise the first section dirty chamber 11 that connects with water inlet 2, reach the second section dirty chamber 12 that connects with river course 3.
Be provided with flap valve 13 between first section dirty chamber 11 and second section dirty chamber 12.In the utility model, flap valve 13 is the lower resistance composite material, and especially light-duty lower resistance composite material is convenient to current and is pushed open.And traditional flap valve damages easily and weight is heavier, and current are difficult to push open sometimes, cause the overflow of the pipeline upper reaches, influence normal draining.Present embodiment adopts light-duty lower resistance composite material flap valve, pours in down a chimney good effect is arranged controlling rain overflow just and river course water.
In addition, referring to shown in Figure 2, in the utility model, flap valve 13 be provided be used for forced discharge lift rope 17.
Like Fig. 2, shown in Figure 4, one holds back pipe 14 is communicated with first section dirty chamber 11.Hold back between 14 and first sections dirty chambeies 11 of pipe and be provided with grid 16.Grid 16 is a composite material.
As shown in Figure 4, grid 16 is plugged in through grid guide groove 15 and holds back between 14 and first sections dirty chambeies 11 of pipe, and can extract, and the decontamination cleaning helps to improve collection efficiency, helps controlling the collection flow, prevents the function stopped up.
During use, at first rain state, the dirty rainwater that has fallen leaves, silt, household garbage etc. gets into first section dirty chamber 11 through water inlet 2; Owing to be provided with flap valve 13, rainwater can not get into second section dirty chamber 12, but passes through the coarse filtration of grid 16; Pipe 14 is held back in entering, enters Sewage Plant and handles.
When the heavy rain state, the water yield is very big, and the rainwater that gets into first section dirty chamber 11 can be pushed flap valve 13 open, gets into second section dirty chamber 12, enters river course 3 then, realizes unobstructed draining flood control function.
When flap valve 13 occurs unexpected or lost efficacy because of service life is long, can also adopt manual work to lead to drag the mode that lifts rope 17 and open flap valve 13, realize forced drainage.
After using certain hour, grid 16 can take out from grid guide groove 15, and cleaning, and taking-up fallen leaves, silt, household garbage etc. can normally be used at the heavy rain state guaranteeing.
The slab culvert of the utility model cuts dirty well, is provided with flexibly, and the few and stability of flow of equipment can not stop up, and can guarantee to receive water under the situation of river course normal function, and operational management is convenient.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
