Abstract
The utility model discloses a kind of phreatic high pressure pipeline drainage system structure.Comprise and be positioned at principal pressure pipe (1) top and in the parallel drainage tunnel (2) of principal pressure pipe be positioned at branch's force pipe (5) top and in the collector drain (3) of principal pressure tube space intersection; Drainage tunnel and collector drain top are equipped with one group of drain hole (4) tilted.The utility model is combined by drainage tunnel and collector drain are carried out arranged crosswise, effectively can be responsible for and arm upper area by overburden pressure pipeline, achieve the effect of drainage pressure-reducing.Solving that phreatic line is high, above pressure pipeline, for carrying out drainage pressure-reducing effect, the problem of drainage tunnel must be arranged every bar pressure pipeline supervisor and each arm.Make the complicated arrangement form of tradition be tending towards simply clear, reduce difficulty of construction and construction costs simultaneously.
Description
Technical field
the utility model relates to a kind of phreatic high pressure pipeline drainage system structure, belongs to the diversion technical field in hydroelectric project.
Background technology
in construction of hydropower plant, above pressure pipeline during phreatic line height, must arrange that drainage tunnel carries out drainage pressure-reducing every bar pressure pipeline supervisor and each lateral, be again very important arrangement form while of being the most general.But in this traditional hydroelectric project design, must main delivery pipe comprised and branch's pressure pipeline every bar pressure pipeline top layout drainage tunnel carries out drainage pressure-reducing, underground cavern excavation difficulty is large, usually at substantial manpower and materials are needed, traditional arrangement form makes to build difficulty and improves, and construction costs is corresponding improve also.
Utility model content
the purpose of this utility model is, provides a kind of phreatic high pressure pipeline drainage system structure, to reduce the construction engineering quantity of drainage tunnel, reduces difficulty of construction and construction costs while effectively carrying out drainage pressure-reducing.Reduce construction cost.
the technical solution of the utility model:
a kind of phreatic high pressure pipeline drainage system structure, comprises and to be positioned at above principal pressure pipe and in the parallel drainage tunnel of principal pressure pipe be positioned at the collector drain intersected above branch's force pipe and in principal pressure tube space; Drainage tunnel and collector drain top are equipped with one group of drain hole tilted.
in aforementioned drainage system structure, the drain hole on described drainage tunnel and collector drain is arranged in a crossed manner, and the face that whole drain hole is formed covers the layout scope of whole branch force pipe.
in aforementioned drainage system structure, described drainage tunnel is identical with collector drain floor level.
in aforementioned drainage system structure, described drain hole symmetry tilts to be located at drainage tunnel or collector drain top.
in aforementioned drainage system structure, the angle of described drain hole and horizontal plane is 30 ~ 60 °.
in aforementioned drainage system structure, the length of described drain hole is no more than the height of waterline.
compared with prior art, the utility model is combined by drainage tunnel and collector drain are carried out arranged crosswise, effectively can be responsible for and arm upper area by overburden pressure pipeline, achieve the effect of drainage pressure-reducing.Solving that phreatic line is high, above pressure pipeline, for carrying out drainage pressure-reducing effect, the problem of drainage tunnel must be arranged every bar pressure pipeline supervisor and each arm.Make the complicated arrangement form of tradition be tending towards simply clear, reduce difficulty of construction and construction costs simultaneously.

Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of phreatic high pressure pipeline drainage system structure, as shown in Fig. 1 ~ 5: comprise and to be positioned at above principal pressure pipe 1 and in the parallel drainage tunnel 2 of principal pressure pipe 1 with to be positioned at above branch's force pipe 5 and in the space crossed collector drain 3 of principal pressure pipe 5; Drainage tunnel 2 and collector drain 3 top are equipped with one group of drain hole 4 tilted.Drain hole 4 on drainage tunnel 2 and collector drain 3 is arranged in a crossed manner, and the face that whole drain hole 4 is formed covers the layout scope of whole branch force pipe 5.Drainage tunnel 2 is identical with collector drain 3 floor level.Drain hole 4 symmetry tilts to be located at drainage tunnel 2 or collector drain 3 top.Drain hole 4 is 30 ~ 60 ° with the angle of horizontal plane.The length of drain hole 4 is no more than the height of waterline.
Embodiment
this example comprises pressure pipeline 1, drainage tunnel 2, collector drain 3 and drain hole 4.Concrete implementation step is as follows:
1, above pressure pipeline 1, drainage tunnel 2 is arranged;
2, drainage tunnel 2 floor elevation answers incorporation engineering entirety to consider to arrange, and is arranged on same elevation with collector drain 3 base plate;
3, the drain hole 4 of drainage tunnel 2 and drain hole 4 arranged crosswise of collector drain 3, require to cover whole pressure pipeline region.
4, groundwater table 7 carries out draining, effective drainage pressure-reducing by drainage tunnel 2 and collector drain 3, solves pressure pipeline top phreatic high pressure problems of too.
