Abstract

The invention discloses an anti-clogging inverted siphon sewage pipe system. The anti-clogging inverted siphon sewage pipe system comprises a water inlet well unit, a multi-folding-angle downslope inverted siphon unit and a water outlet well unit, wherein the water inlet well unit consists a water inlet front chamber which is communicated with a sewage inlet pipe and a first water inlet rear chamber and a second water inlet rear chamber which are independent; the multi-folding-angle downslope inverted siphon unit consists of a first inverted siphon and a second inverted siphon which have the same structure and are horizontally abreast arranged; the water outlet well unit consists a first water outlet rear chamber and a second water outlet rear chamber which are independent and a water outlet front chamber. The anti-clogging inverted siphon sewage pipe system has the advantages that since the sewage pipe which penetrates through obstacles adopts the multi-folding-angle downward inverted siphon manner, not only can silt be effectively washed, but also the pipe system can adapt to situations of wider river shoal and river surfaces and deeper river beds, the applicability is strong, the head loss is small because the inverted siphon adopts the multi-angle downward configuration manner, the washing is facilitated, silt can be effectively prevented from being deposited in the pipe and thereby the anti-clogging effect is achieved.

Description

The invention has the advantages that the sewage conduct that will be travelling through barrier adopts described many knuckles along the form of falling rainbow on slope, can The situation that effectively erosion and deposition adapts to river shoal again Yu river surface is wider, riverbed is deeper, strong applicability.Before to first, second water inlet Room and the opening and closing of water outlet cup gate, form the sewage conduct upstream and downstream liquid level discrepancy in elevation, using the gravitational potential of sewage itself Can, wash away inverted siphon, improve pipe flow speed.Inverted siphon adopts multi-angle along slope arrangement form, and the loss of flood peak is little, is easy to wash away, Deposition in pipeline can be prevented effectively from, thus reaching the effect of silting blocking.

Brief description

Fig. 1 is the structural representation of the present invention.

Fig. 2 is the overlooking the structure diagram of Fig. 1.

Specific embodiment

As shown in Figure 1, 2, silting blocking formula inverted-siphon sewer system of the present invention, including inlet well unit, many Knuckle is along slope inverted siphon unit, wet well unit；

Described inlet well unit is by the water inlet cup 2 being connected with sewage water inlet pipe 1, and the first of two upper shed structures Water inlet rear chamber 3.1 and the second water inlet rear chamber 3.2 form；In water inlet cup 2 first ultrasonic level gage 4 is installed, first, second The gate 6.1,6.2 that water inlet rear chamber 3.1,3.2 is passed through to be controlled by screw open-close machine 5 respectively is connected with water inlet cup 2, first, The water outlet of the second water inlet rear chamber 3.1,3.2 is respectively arranged with grating type spotter 7.1,7.2；

Described many knuckles are along slope inverted siphon unit by structure is identical and first inverted siphon and second of horizontal Tile setting falls Tube forms；I.e. first, second inverted siphon slow is delayed along pipe along pipeline section 8, inclined tube section 9, second by the first of: identical slope aspect arrangement Section 10 composition；First slow suitable pipeline section 8, inclined tube section 9, second delay the gradient of suitable pipeline section 10 by inlet well unit slope aspect wet well list Unit's setting；First, second inverted siphon first slow along pipeline section 8 respectively with the going out of corresponding first, second water inlet rear chamber 3.1,3.2 The mouth of a river is connected；

Described wet well unit includes two the first independent water outlet rear chamber 11.1 and the second water outlet rear chamber 11.2 and goes out Water cup 12 forms；Water outlet cup 12 is provided with the second ultrasonic level gage 13；First, second 11.1,11.2 points of water outlet rear chamber The gate 15.1,15.2 that Tong Guo not controlled by screw open-close machine 14 is connected with water outlet cup 12, and water outlet cup 12 and sewage go out Water pipe 16 is connected；First, second inverted siphon second slow along pipeline section 10 respectively with corresponding first, second water outlet rear chamber 11.1st, 11.2 be connected；The diapire of water outlet cup 12 is higher than the diapire of first, second water outlet rear chamber 11.1,11.2.

The first, second slow gradient >=1/d along pipeline section 8,10, d are the first or second slow diameter along pipeline section 8,10, unit For millimeter；Downward corner a >=30 degree of inclined tube section 9.

Silting blocking work process of the present invention is summarized as follows:

First, arrange the silt operating mode method of operation:

The first step, it is first shut off into the gate 6.1,6.2,15.1,15.2 in water cup 2 and water outlet cup 12, by entering The water level of the first ultrasonic level gage 4 detection water inlet cup 2 installed in water cup 2, after sewage harmony up to designated water level, according to The secondary gate 15.1 opened in the gate 6.1 and water outlet cup 12 that the first inverted siphon is intake in cup 2, by the high hydraulic potential of harmony Alluvial in pipeline can be reduced along the impurity of alluvial in plug-flow the first inverted siphon of slope；

Second step, it is then shut off into the gate 6.1,15.1 in water cup 2 and water outlet cup 12, by intaking in cup 2 The water level of the first ultrasonic level gage 4 detection water inlet cup 2 installed, after sewage harmony up to designated water level, opens the successively The gate 15.2 in gate 6.2 and water outlet cup 12 that two inverted siphons are intake in cup 2, is pushed away along slope by the high hydraulic potential of harmony Flow the impurity of alluvial in the second inverted siphon, reduce alluvial in pipeline.

2nd, overhaul the operating mode method of operation:

The first step, the gate 6.2,15.2 closed in water inlet cup 2 and water outlet cup 12, then adopt movable submersible to arrange Dirty pump evacuates the water of the second water outlet rear chamber 11.2, stops suction after evacuation；Sewage harmony up to designated water level in water cup 2 to be entered Open afterwards, into the gate 6.2 in water cup 2, desilting is carried out to the second inverted siphon, until after the second inverted siphon water outlet is smooth, then beat Output the gate 15.2 in water cup 12.

Second step, the gate 6.1,15.1 closed in water inlet cup 2 and water outlet cup 12, then adopt movable submersible to arrange Dirty pump evacuates the water of the first water outlet rear chamber 11.1, stops suction after evacuation；Sewage harmony up to designated water level in water cup 2 to be entered Open afterwards, into the gate 6.1 in water cup 2, desilting is carried out to the first inverted siphon, until after the first inverted siphon water outlet is smooth, opening Gate 15.1 in water outlet cup 12.

The present invention can effectively utilizes water body self gravitation potential energy, arrange in pairs or groups many knuckles along domatic formula inverted siphon, formed water From rushing operating mode, along sedimentation impurity in the plug-flow inverted siphon of slope, the what effectively reducing in inverted siphon blocks up power, extends the use longevity of inverted siphon Life, improves the safety guarantee rate of sewer system, adapts to different pass through situation simultaneously again.
