Detailed description of the invention

Below in conjunction with preferred embodiment, the present invention is described in further details; elaborate more details in the following description so that fully understanding the present invention; but; the present invention obviously can implement in multiple these other modes described that are different from; those skilled in the art can make similar popularization according to practical situations, deduce in the case of intension of the present invention, the most should be with content constraints protection scope of the present invention of this specific embodiment.

Fig. 1-5 is the schematic diagram of embodiments of the invention, it should be noted that this accompanying drawing is only used as example, is not to draw according to the condition of equal proportion, and should not be construed as limiting in this, as to the actual requirement protection domain of the present invention.

A kind of multi-functional municipal administration rainwater discharge outlet, it is applicable to the rainwater such as rainpool, Rain-fed wetland, Rain Garden, the dry pool arrange, delay adjustment for above-mentioned stormwater facility controls, described floss hole uses the design philosophy of multistage prolongation runoff stop/holdup time, on the basis of limited volume adjusted, reached the target of Multistage Control by the appropriate design of floss hole, diameter stream carries out On-line precipitation purification simultaneously, it is thus achieved that preferably effluent quality.

A kind of multi-functional municipal administration rainwater discharge outlet, including concrete foundation 8, the overflow borehole wall 7, municipal administration outlet 3, sidepiece overflow ducts and top overflow ducts, well body 10, municipal administration outlet 3 that described sidepiece overflow ducts and top overflow ducts are surrounded by the overflow borehole wall 7 are connected with municipal pipeline, when the water level in stormwater facility is relatively low, rainwater can slowly enter municipal administration outlet 3 by sidepiece overflow ducts, when the water level in stormwater facility is higher, rainwater can rapidly enter municipal administration outlet 3 by top overflow ducts, tentatively realizes the Two-stage control of rainwater；

Described sidepiece overflow ducts includes sidepiece overflow grating 1 and side overflow mouth 5, described sidepiece overflow grating 1 is fixing with the pre-embedded steel slab 2 being arranged on the overflow borehole wall 7 sidewall to be connected, different according to the water level in stormwater facility, realizing the grading control of side overflow mouth 5 in sidepiece overflow ducts, sidepiece overflow grating 1 can prevent the bulky grain pollutant such as weeds, leaves, rubbish from entering well body 10；

Described top overflow ducts includes that top overflow grating 4 and top overfall 6, described top overflow grating 4 are arranged on the top of the overflow borehole wall 7, and top overflow grating 4 can prevent the bulky grain pollutant such as weeds, leaves, rubbish from entering well body 10.

The described overflow borehole wall 7 is arranged by Prefabricated block splicing, can realize low cost construction and the Fast Construction of discharge outlet.

Described Prefabricated block is plastic material, the Prefabricated block light weight of plastic material, corrosion-resistant, and service life is long, convenient transport and building.

Described plastic material is PP material or PE material.

Described top overflow grating 4 is connected with the top of the overflow borehole wall 7 by hinge.

Described side overflow mouth 5 includes one-level overfall 51 and two grades of overfalls 52, described one-level overfall 51 is positioned at below two grades of overfalls 52, when rainwater is less, runoff enters well body 10 by one-level overfall 51, when rainwater is bigger, runoff enters well body 10 by one-level overfall 51 and two grades of overfalls 52, adds the emission flow of runoff.

Described side overflow mouth 5 uses T-shape structure, described one-level overfall 51 to be positioned at T-shape mouth bottom, and described two grades of overfalls 52 are positioned at T-shape mouth top.

Described side overflow mouth 5 uses " V " type structure, described one-level overfall 51 to be positioned at " V " type mouth bottom, and described two grades of overfalls 52 are positioned at " V " type mouth top.

Described sidepiece overflow grating 1 is that rectangle is circular or trapezoidal, and the shape of described sidepiece overflow grating 1 is not limited to above-mentioned shape.

Described top overflow grating 4 is rectangle or circle, and the shape of described top overflow grating 4 is not limited to above-mentioned shape.

The height of described municipal administration outlet 3, higher than the bottom of well body 10, can realize the partial storage function of well body 10 when the bottom of well body 10 is lower.

The described municipal administration height of outlet 3 flushes with the bottom of well body 10.

The bottom of described well body 10 is provided with the slope tilted to municipal administration outlet 3.

When rainwater is less, rainfall runoff enters well body 10 by the one-level overfall 51 of sidepiece overflow ducts, enters municipal pipeline, owing to the path of one-level overfall 51 is less by municipal administration outlet 3, the speed that rainfall runoff is discharged effectively is slowed down, and adds the dead time of rainfall runoff；

When rainwater is bigger, rainfall runoff enters well body 10 by one-level overfall 51 and two grades of overfalls 52 of sidepiece overflow ducts, enters municipal pipeline, now by municipal administration outlet 3, the discharge capacity of sidepiece overflow ducts is fully used, and the mass rate of emission of rainfall runoff significantly improves；

When rainwater be the precipitation such as heavy rain very big in the case of, rainfall runoff is discharged by sidepiece overflow ducts and top overflow ducts simultaneously, and rainwater mass rate of emission promotes again；

In the case of precipitation is high, rainfall runoff is only capable of being discharged by sidepiece overflow ducts and top overflow ducts simultaneously, can control crest discharge.

Above content is the explanation of the preferred embodiment to the invention, and those skilled in the art can be helped to be more fully understood by the technical scheme of the invention.But, these embodiments are merely illustrative, it is impossible to assert that the detailed description of the invention of the invention is only limitted to the explanation of these embodiments.For the invention person of an ordinary skill in the technical field, without departing from the concept of the premise of the invention, it is also possible to make some simple deductions and conversion, all should be considered as belonging to the protection domain of the invention.
