Description

Large-flow, high-level siphoning installation

The utility model relates to the high chord position siphoning installation of a kind of big flow that engineering construction is used.

When in the rivers,lakes and seas waters, carrying out the building of various different object of construction production at present, caisset as the basic current extensive use of aquatic building thing.And the sinking device of caisson, it is important that workmanship, cost are caused the pass.Traditional sinking device, the employing submersible pump unit that has is about to the outer water of caisson and constantly pumps in the caisson, until filling, makes at the bottom of the caisson seat.Significantly weak point is: operation at sea district domestic demand has huge sends out (failing) electric system as power supply, and its complex structure, easy break-down, maintenance capacity are big; Capacity of equipment is limit, and construction operation is wanted the long period; Equipment, operating cost are more expensive, cause construction costs higher.The employing case valve gear that also has is promptly increasing UNICOM's pipeline between dress Jones's valve and cabin on the Bottom plate of sinkbox, valve closing in caisson transportation by driving, the parking period, permanent opening after reaching during sinking.Its weak point still is: the sinking device is disposable utilization, and this will waste a large amount of valves and pipeline, and anticorrosion being difficult to handles; Change the globality of caisset, and be not easy to again renovation and utilization (as transforming oil depot into) after placing the bottom; Increased many difficulties for the loading seat end and complement pile.

The purpose of this utility model is to provide a kind of improved big flow high chord position siphoning installation, it can be effectively need not electric energy, rapid and simple realization sinking caisson, simple in structure, with low cost.

The purpose of utility model is achieved in that an inverted U-shaped pipe, and two ends respectively is communicated with inlet valve and flowing water Valve by flare type joint, and the tube wall of U-shaped pipe extreme higher position is equipped with the device that binds that is communicated with in the U-shaped pipe outward.

The device that binds can be that a pipeline section that is communicated with in the U-shaped pipe is equipped with in said position, and valve is equipped with in its termination, opens or closes.

The device that binds can be that the pipeline section that is communicated with in the U-shaped pipe and is with interior screw thread is equipped with in said position, and joint ring is equipped with in its termination, with plug pipeline section is opened or closed.

The device that binds also can be that the pipeline section that is communicated with in the U-shaped pipe and has flange is equipped with in said position, is lined with joint ring on the flange, with the flanged plate of being with inner convex platform pipeline section is opened or closed.

The device that binds can also be that two pipeline sections that are communicated with side by side and all in the U-shaped pipe are equipped with in said position, and valve is equipped with in each termination, opens or closes from pipeline section individual.

The advantage of utility model: in 1 meter environment of water-head, 8 inch pipe siphoning installation result of the tests show: the high potential water surface to U-shaped pipe pipe heights of roofs can reach 9.8 meters, flow can reach 240 meters ³/ hour; Need not the energy during work, stable and reliable operation and operation area occupied are little; Simple in structure, be easy to make and operation, can reuse, overall economic efficiency is remarkable.

Description of drawings:

Fig. 1 is the front view of the high chord position siphoning installation of a kind of big flow;

Fig. 2 is that (being that a kind of device master of binding looks) figure amplifies in the I portion of Fig. 1;

Fig. 3 is the another kind device front view that binds;

Fig. 4 is another device front view that binds.

Below in conjunction with details and the working condition of Fig. 1-4 detailed description according to the concrete device that the utility model proposes.

This device comprises an inverted U-shaped pipe 2, selects the metal tube of suitable diameter to make, and two branches have equal length and side by side, also can be to have slightly unequal length and be gradually to put shape.U-shaped pipe two ends all are shaped on flare type joint 4, and its enlarged ratio is 1:1-2.4, and this is in order to increase the cross-section of river, to replenish the drag losses of valve.One of the flare type joint inlet valve 1 that is tightly connected, another flowing water Valve 5 that is tightly connected, they all select getting final product of conventional suitable bore.The tube wall of U-shaped pipe extreme higher position is equipped with the device that binds that is communicated with in the U-shaped pipe outward.

The enforcement structural concept of device of binding is more, and existing only have being described as follows of typicalness.The device 3 that binds of Fig. 2 introduction, it is outside the tube wall of said position, is welded with the pipeline section 6 that is communicated with in the U-shaped pipe, the horn mouth that gradually put screw thread and lower end in this pipeline section was shaped on, joint ring 7 is equipped with in the upper surface, realizes opening or closing with the 8 pairs of pipeline sections of plug that match with screw thread in the pipeline section.Or not shown said pipeline section, structure as hereinbefore, different is that the upper end is shaped on male thread, and joint ring is housed equally, with the silk cap of screw thread in being shaped on and the heart portion inner convex platform pipeline section is opened or closed.

The another kind shown in Figure 3 device that binds, on said position, be welded with the pipeline section 9 that is communicated with in the U-shaped pipe, its upper end sealing is welded with the flange 10 of suitably making through hole in same circumference, is lined with joint ring 11 on the flange, and flanged plate 12 is shaped on through hole corresponding with the flange through hole and heart portion inner convex platform.Pass the through hole of flange, plate with the screw pair, can realize flanged plate opening or closing pipeline section.

Fig. 4 illustrates another device that binds, and this is outside the U-shaped tube wall of said position, is welded with

pipeline section

13 and 14, and wherein the length of pipeline section 13 slightly is longer than pipeline section 14, and they are in state arranged side by side substantially and all are communicated with in the U-shaped pipe.A valve respectively is equipped with in their termination of exposing, and can open or close individual pipeline section certainly.

The most easy not shown device that binds is outside the U-shaped tube wall of said position, is welded with a pipeline section that is communicated with in the U-shaped pipe, exposes the termination valve is housed, and directly pipeline section is opened or closed.

Working condition is such, this device is placed job position according to Fig. 1 (caisson is represented in double dot dash line), its branch that inlet valve 1 is housed is inserted in the high potential waters, and the branch that flowing water Valve 5 is housed freely overhangs in the caisson cabin, and valve all is in closed condition.Open the device that binds, promptly spin off plug 8(and contain said silk cap), or remove flanged plate 12, or open the valve of

pipeline section

13 and 14, or open the valve of single pipeline section.To the U-shaped pipe with bind and fill water in the device, should ensure that gas fully discharges.Close the device that binds, i.e. traling plug (containing a cap), or dress closes flanged plate, or the valve of closing pipeline section 14 earlier closes the valve of pipeline section 13 again, or close the valve of single pipeline section.According to successively opening

valve

1 and 5, according to the effect of siphon, the water in the high potential waters will be along pouring in the U-shaped pipe in the caisson cabin, until this cabin of caisson is filled so.Take out this device, move to other freight space, continue operation as previously mentioned.Flanged plate or the related heart portion inner convex platform of silk cap, and plug are in closing the device process that binds, and allow its interior water section overflow, and fully discharge gas, so that more effectively improve siphon effect.
