Description

The drainage equipment examination and repair system of mud leakage water
Technical field
The utility model relates to dam mud leakage water draining technology, belongs to Hydraulic and Hydro-Power Engineering field.
Background technology
It in order to discharge the percolating water in dam depended on two sides massif therewith, bottom dam, is provided with seepage drainage catchments Well and draining pump house, in order to discharge percolating water in dam body in time, to ensure the operation safety of dam.Dam is from foundation dredging To dam top pouring, often last for several years, even in order to ensure the safety of dam, after dam cast is bound, in dam Still in the grouting carrying out necessity and closure in portion's each layer gallery, to guarantee that dam is even gone up a century in coming few decades and can be stablized And safe operation.Seepage of dam drainage system then puts into operation already, containing high calcareous concrete during dam grouting Mud is unavoidably mixed into the percolating water of dam, along each layer seepage drainage gallery, is finally pooled to the seepage collection bottom dam Well, is discharged outside factory by drainage system.
Owing to seepage sump is typically located at the bottom of dam, and have inconvenient traffic, the concrete being deposited in sump Cannot discharge smoothly, be substantially all and need to be discharged by draining pump and drainpipe, the water quality density owing to being mixed with concrete is long-range In normal water quality density, draining pump power of motor is in overload operation, long-play, then the draining pump life-span significantly shortens, if Standby fault rate is higher, and even some power station equipment faults cause cannot discharging percolating water in time, affect dam safety;This type of draining Pump is many with longer lifting pipe, and dismounting is time-consumingly longer, and it is laborious to take a lot of work, and also brings very big puzzlement to operation maintenance personnel, Currently also there is no preferable way to solve problems.
It is, thus, sought for safer reliable drainaging scheme and system operation maintenance mode, to reduce the event of equipment Barrier rate, improves the reliability of drainage system, it is ensured that the operation safety of dam.
Content of the invention
Technical problem to be solved in the utility model is to provide the drainage equipment examination and repair system of a kind of mud leakage water, energy Enough in the case of not removing lifting pipe, realize Quick overhaul drainage equipment.
The drainage equipment maintenance that the utility model solves technical problem the technical scheme is that mud leakage water is System, including water drain pump assembly, the pipeline that pumps up water, high-lift bridge machine, hang thing hole and hang object depth well, described water drain pump assembly is arranged Bottom dam, described discharge pipe line is arranged in dam top, and described discharge pipe line and described water drain pump assembly are by pumping up water Pipeline connects, and the described pipeline that pumps up water includes the many end to end tube couplings that pump up water, and the bottom of the described pipeline that pumps up water is provided with support dress Putting, described support means is fixedly mounted on bottom dam, and described support means connects water drain pump assembly;Described thing hole of hanging is arranged At dam top, and being connected to bottom dam by hanging object depth well, described high-lift bridge machine by hanging thing hole and can hang object depth Described water drain pump assembly is lifted on the floor above the sump bottom dam change or keep in repair by well.
While using technique scheme, the utility model can also use or combine employing further below Technical scheme:
Described support means is removable with described water drain pump assembly to be connected.
Described support means is removable with the tube coupling that pumps up water of described pipeline bottom of pumping up water to be connected.
The beneficial effects of the utility model are: the utility model can be under conditions of not dismantling lifting pipe, it is achieved water pump The maintenance of unit, substantially increases water pump assembly overhaul efficiency, improves the operational reliability of equipment.
Brief description
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the sectional side elevation of Fig. 1.
Detailed description of the invention
Referring to the drawings.
The drainage equipment examination and repair system of mud leakage water of the present utility model, including the 10th, water drain pump assembly pumps up water pipeline 4th, the 8th, high-lift bridge machine hangs thing hole 7 and hangs object depth well 11, and described water drain pump assembly 10 is arranged in bottom dam, described drainpipe Road is arranged in dam top, and described discharge pipe line and described water drain pump assembly 10 are connected by the pipeline 4 that pumps up water, described lifting pipe Road 4 includes the many end to end tube couplings 19 that pump up water, and the described bottom pumping up water pipeline 4 is provided with support means 20, and described support fills Putting and being fixedly mounted on bottom dam, described support means 20 can connect and support described water drain pump assembly;Described hang thing hole 7 Being arranged on dam top, and being connected to bottom dam by hanging object depth well 11, described high-lift bridge machine 8 can be by hanging thing hole 7 With hang object depth well 11 be lifted to described water drain pump assembly 10 on the floor above the sump bottom dam to carry out to change or Maintenance.
Further, described support means 20 is removable with described water drain pump assembly is connected.
Further, described support means 20 and described pipeline 4 bottom of pumping up water pump up water that tube coupling 19 is removable to be connected.
When water pump assembly breaks down, by removing two joint lifting pipes 19 above support means 20, support means 20 Can temporarily support the weight of water pump assembly 10, boom hoisting is fixed on top pump up water on tube coupling, utilize boom hoisting will Water pump assembly is lifted on the floor above sump 12, utilizes trailer to be dragged to hang near thing vertical shaft, utilizes high-lift bridge machine 8 to hang Change or keep in repair to the preferable pump house of repair and maintaining, can avoid removing the substantial amounts of tube coupling that pumps up water, shorten maintenance dimension Protect the time.
