Fig. 1 is water circulation system application implementation illustration intention of the present invention.
The specific embodiment
For ease of structure of the present invention and the effect that reaches are had further understanding, combine the accompanying drawing preferred embodiment that develops simultaneously to specify as follows at present.
As shown in Figure 1; The deep foundation ditch that large-scale well-sinking that water circulation system of the present invention is used to adopt the waterpower method to fetch earth sinks or employing waterpower method fetch earth and construct; This water circulation system includes to open caisson or deep foundation ditch 1 water system that supplies water and the plasma discharge system that the mud in open caisson or the deep foundation ditch 1 is discharged, and this water system one end is located at open caisson or deep foundation ditch 1, and the other end is located at rivers; This plasma discharge system one end is located at open caisson or deep foundation ditch 1, and the other end is arranged at fluviatic mud carrier 2.
Water system among the present invention includes the platform 30 that draws water on the rivers, is located at powerful water supply gravel pump 31 and water supply line 32 on the platform 30 that draws water; These water supply line 32 1 ends connect water supply gravel pump 31; The other end is located at open caisson or deep foundation ditch 1; This water supply gravel pump 31 pumps into fluviatic water in open caisson or the deep foundation ditch 1 through water supply line 32, and single water supply gravel pump 31 supplies water and carries maximum horizontal range can reach 3Km, i.e. the water supply line 32 the longest 3Km that can be; If can in the middle of water supply line 32, set up one or several water supply gravel pump water relays again when distance is far away, this water supply line 32 can be hard plastic tube.Plasma discharge system among the present invention includes inhales mud equipment 40, plasma discharge flexible pipe 41, mud transfer pond 42, powerful plasma discharge gravel pump 43 and plasma discharge pipeline 44; Inhaling mud equipment 40 is located in open caisson or the deep foundation ditch 1; Be used for entering in the mud transfer pond 42 with the mud sucking-off of open caisson or deep foundation ditch 1 and through plasma discharge flexible pipe 41; Plasma discharge gravel pump 43 pumps into mud carrier 2 with the mud in the mud transfer pond 42 through plasma discharge pipeline 44; Single plasma discharge gravel pump 43 plasma discharges carry maximum horizontal range can reach 3Km, i.e. plasma discharge pipeline 44 the longest 3Km that can be are if can set up one or several plasma discharge gravel pump relay plasma discharges when distance is far away again in the middle of plasma discharge pipeline 44; This plasma discharge pipeline 44 can be hard plastic tube, and the suction mud equipment 40 among the present invention can be slush pump, air suction dredge or stirs sucking pump.
The end that plasma discharge pipeline 44 among the present invention is positioned at mud carrier 2 also can be provided with and be positioned at fluviatic buoyancy tank platform 45, in order to plasma discharge pipeline 44 is carried out supporting.Plasma discharge gravel pump 43 among the present invention per hour can be distinguished pumping 1450m with water supply gravel pump 31
3Mud and water, the diameter of plasma discharge flexible pipe 41 can be 273mm, plasma discharge pipeline 44 can be 315mm with the diameter of water supply line 32, the length in mud transfer pond 42 is 20m, wide is 10m.Plasma discharge gravel pump 43 among the present invention can be many with water supply gravel pump 31, and plasma discharge pipeline 44 and water supply line 32 have the quantity identical with plasma discharge gravel pump 43 and water supply gravel pump 31 respectively.This suction mud equipment 40 can be many, inhales mud equipment 40 for every and connects a plasma discharge flexible pipe 41.
The concrete course of work of water circulation system of the present invention is following:
The first step starts the water supply gravel pump on the platform that draws water, and rivers water is evacuated in open caisson or the deep foundation ditch through water supply line;
In second step, the water in open caisson or deep foundation ditch satisfies the waterpower method and fetches earth behind the construction requirement, starts the mud equipment of inhaling, and the soil body in open caisson or the deep foundation ditch is formed mud, drains into mud transfer pond through inhaling mud equipment and plasma discharge flexible pipe;
In the 4th step, the mud in mud transfer pond reaches a half and starts the plasma discharge gravel pump that plasma discharge is used, and drains into mud on the mud carrier that berths in the rivers through the plasma discharge pipeline;
In the 5th step, the mud on the mud carrier flows back to rivers through the post precipitation clear water, and waste water transport to spoil ground or demand place when big, need to increase the quantity of mud carrier like the plasma discharge amount, satisfy the time requirement of construction requirement and mud sediment;
The 6th step stopped to inhale the bricklayer when doing, and inhaled clear water to mud transfer pond with inhaling mud equipment earlier, and plasma discharge gravel pump and plasma discharge pipeline stop to inhale the mud equipment availability through flushing with clean water after clean, stop water supply, the operation of plasma discharge gravel pump again.
The advantage and the existing hydraulic set of bridge construction water route, river transportation striden in utilization of the present invention; The mud that open caisson water force method is discharged enters small-sized mud transfer pond; By high-power plasma discharge gravel pump mud is delivered in the mud carrier along the river through the plasma discharge pipeline at a distance again; Mud flows back in the river through the deposition clear water, and dregs is transported to the spoir place by mud carrier through the water route.The open caisson moisturizing directly utilizes high-power water supply gravel pump that mud is delivered in the open caisson through water supply line at a distance.
The present invention can solve large-scale well-sinking waterpower method fetch earth narrow and small, environmental protection in construction plant and the difficult problem of civilized construction in the construction well; Other deep foundation pit of construction fetches earth also and can replace mechanical equivalent of light excavation through the construction of waterpower method, and dregs forms omnidistance line transportation behind the mud, has solved to adopt time restriction, the traffic safety on the dregs car outward transport dregs and problem such as stir up a cloud of dust.Water circulation system of the present invention was applicable to river suspension bridge anchorage construction of Open Caisson Foundation, deep foundation ditch fetches earth and other building construction of Open Caisson Foundation, particularly constructed than the very limited similar engineering of comparatively dense and construction plant at municipal engineering, surrounding building.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
