Description
Technical field
The utility model relates to the rock technical field, particularly relates to rock construction period reverse osmosis drainage system.
Background technology
In Hydraulic and Hydro-Power Engineering, because of irrigation draught or generating etc. need, the formation reservoir of will building a dam usually, numerous dam Selection Floater loose rock dam of founding a capital and planning to build.Rock upstream side plinth foundation generally all is seated on complete, the hard basement rock; Because of toe board and toe board inner slope excavation darker; Cause dam foundation upstream side to be lower than the downstream, construction period dam district's construction water and rainwater etc. can not freedom be discharged downstream, are pooled to the dam body upstream side; Form reverse head, dam body upstream side bedding material, panel and panel water-stopping system can be owing to water pressure is destroyed.Therefore, timely and effectively the reverse water in the dam body is drained most importantly, generally need construction period reverse drainage system is set at the dam body upstream side.Conventional counter drainage system complex process, cost height are built interference greatly to dam embankment and panel, influence the duration, and later stage operation and shutoff are inconvenient.
Summary of the invention
The utility model technical problem to be solved is to overcome the defective that existing reverse drainage system process is complicated, cost is high; A kind of rock construction period reverse osmosis drainage system is provided; This system can the reverse water of convenient effective discharge, and simple in structure, the arrangement convenience of system, and cost is low.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model rock construction period reverse osmosis drainage system: in the horizontal interface in transition region 10 and enrockment district, the upper reaches 11, lay the blind material 1 of draining; The blind material 1 upstream side splicing sleeve 2 of draining; The opposite side of sleeve pipe 2 connects horizontal drain pipe 3, and the opposite side of horizontal drain pipe 3 connects scupper hose 5, and the other end of scupper hose 5 places in the collecting well 6; Other establishes vertical drainage pipe 7, and vertical drainage pipe 7 lower ends connect 13 and are connected with horizontal drain pipe 3 through curved.
Above-mentioned rock construction period reverse osmosis drainage system is provided with unidirectional sealing valve 4 on horizontal drain pipe 3.Unidirectional sealing valve 4 permission dams Nei Shui discharges, and does not allow dam Wai Shui to pour in the dam.
Aforementioned reverse osmosis drainage system is all established joint screw thread in the outside, two ends of horizontal drainage steel pipe 3, the installation after dismounting when making things convenient for the panel construction and panel have been built.
Aforementioned reverse osmosis drainage system, vertical drainage pipe 7 upper ends link to each other with lengthening vertical drainage pipe 7 with another section steel pipe through direct 14.
Compared with prior art, the utility model is established the blind material of draining as dam internal drainage passage in the water in dam tiling, makes things convenient for the dam body construction, reduces construction and disturbs, and the reduction of erection time, reduces investment outlay; Members such as the blind material of draining, gutter, unidirectional sealing valve are less relatively, transportation and easy for installation flexible, and it is little that counter plate weakens scope; Adopt nipple that horizontal drain pipe and sleeve pipe are joined, conveniently dismounting had made things convenient for slding form operation when panel was built; The installation of unidirectional sealing valve not only can under normal circumstances move; Also can normally move during the dam body temporary water dash in flood season; Can prevent to catchment outside the dam, the upper reaches pours in the dam, prevents that mud and rubbish stop up drainage system outside the dam, external water pressure in the balance dam body voluntarily behind the flood.The present invention is specially adapted to that section plinth foundation excavation in riverbed is dark, upstream apron fills long, dam body of duration and need cross the reverse drainage of the rock construction period of flood dash.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Rock construction period reverse osmosis drainage system is as shown in Figure 1, in the horizontal interface in transition region 10 and enrockment district, the upper reaches 1, lays the blind material 1 of draining, the blind material 1 upstream side splicing sleeve 2 of draining; The opposite side of sleeve pipe 2 connects the horizontal drain pipe 3 that has unidirectional sealing valve 4; Joint screw thread is all established in the outside, two ends of horizontal drainage steel pipe 3, and its opposite side connects scupper hose 5, and the other end of scupper hose 5 places in the collecting well 6; Other establishes vertical drainage pipe 7; Other establishes vertical drainage pipe 7, and vertical drainage pipe 7 lower ends connect 13 and are connected with horizontal drain pipe 3 through curved, and vertical drainage pipe 7 upper ends are passed through direct 14 and linked to each other with the vertical drainage pipe 7 that extends with another section steel pipe.
Rock construction period reverse osmosis water processing method is following:
After rock upstream side horizontal segment transition region 10 placement grindings are accomplished; The blind material 1 of the circular draining of the horizontal laying high-strength degree of the medium position of each piece panel 8 of section in the riverbed; The upstream side of the blind material 1 of draining is laid the upstream edge in the enrockment district 11 to the upper reaches; Connect steel sleeve 2 at blind material 1 upstream side of draining; The upstream side of steel sleeve 2 aligns with the panel that will build 8 surface line; The upstream side that is connected on steel sleeve 2 in the horizontal drainage steel pipe 3 of unidirectional sealing valve 4 will be installed then, an end of scupper hose 5 be external in adopt steel wire to tighten and 9 lay to collecting well 6 on the horizontal drainage steel pipe 3, and adopt the pump drainage facility that the water in the collecting well 6 are evacuated to outside the upstream cofferdam with toe board 12 along the bed course district; Sheetpile masonry dam construction face to face is when building panel 8; For ease of slding form operation, pull down the horizontal drainage steel pipe 3 that is about to build the panel place temporarily, when panel is built steel sleeve 2 ends are protected; Prevent to stop up; And leave aperture herein, again horizontal drainage steel pipe 3 is connected with steel sleeve 2 after panel 8 constructions are accomplished, and this place's aperture periphery is repaired.
When flood season, dam body needed temporary water dash, pull down external scupper hose 5, drain upper reaches foundation ditch water behind the flood after, more external scupper hose is connected, guarantee that panel, toe board and water-stopping system are in dry state, repair and sealing construction in the crack of being convenient to toe board, panel.
When upstream apron fills to horizontal drainage steel pipe 3 elevations; Remove external scupper hose 5 earlier, more external vertical drainage steel pipe 7 is connected in horizontal drainage steel pipe 3 upstream sides through the curved joint 13 of steel pipe, external vertical drainage steel pipe 7 is established direct joint 14; Fill intensity one section one section lengthening gradually according to bedding; External water pressure in being convenient in the balance dam is when the bedding height fills when being higher than the free draining elevation 1m in downstream～2m, with the method shutoff of vertical drainage steel pipe 7 employing gravity flow cement groutings.
