In Hydraulic and Hydro-Power Engineering, because irrigation draught or generating etc. need, the formation reservoir of usually will building a dam, 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, hard basement rock, because of toe board and toe board inner slope excavation darker, cause dam foundation upstream side lower than the downstream, construction period dam district's construction water and rainwater etc. can not freely be discharged downstream, be pooled to the dam body upstream side, form reverse head, dam body upstream side bedding material, panel and panel water-stopping system can destroy due to water pressure.Therefore, timely and effectively the reverse water in dam body is drained most importantly, generally need at the dam body upstream side, the construction period reverse drainage system is set.Conventional counter drainage system complex process, cost are high, dam embankment and panel are built disturb greatly, affects the duration, later stage operation and shutoff inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing reverse drainage system complex process, defective that cost is high, a kind of CFRD during Construction reverse osmosis water processing method and a kind of reverse osmosis drainage system are provided, this system can the reverse water of convenient effective discharge, and simple in structure, the arrangement convenience of system, cost is low.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
CFRD during Construction reverse osmosis water processing method of the present invention comprises the steps:
1), after rock upstream side horizontal segment transition region 10 placement grindings are completed, level is laid the blind material 1 of draining, at the blind material 1 upstream side splicing sleeve 2 of draining, the upstream side of sleeve pipe 2 aligns with panel 8 surface line that will build, the horizontal drain pipe 3 that then one-way water stop valve 4 will be installed is connected to the upstream side of sleeve pipe 2, one end of scupper hose 5 is external on horizontal drain pipe 3 and along bed course district 9 and toe board 12 lays to collecting well 6, adopt the pump drainage facility that the water in collecting well 6 is extracted out;
2), sheetpile masonry dam construction face to face is when building panel 8, pull down horizontal drain pipe 3, stay aperture at sleeve pipe 2 end panel places during construction, after completing, panel 8 construction again horizontal drain pipe 3 is connected connection with sleeve pipe, when upstream apron fills to horizontal drain pipe 3 elevation, remove external connection row water tube hose 5, again external vertical drainage pipe 7 is connected in horizontal drain pipe 3 upstream sides, fill intensity according to bedding and lengthen gradually external vertical drainage pipe 7, when the bedding height fills to higher than downstream free drainage elevation 1m～2m the time, with 7 shutoff of vertical drainage pipe.
In above-mentioned processing method, the upstream side of the blind material 1 of draining is laid the upstream edge to upstream rockfill area 11.The blind material 1 of draining is layed in the level of panel 8 to medium position.Vertical drainage pipe 7 adopts the method shutoff of gravity flow cement grouting.
Reverse osmosis drainage system of concrete face rockfill dam in construction period of the present invention: lay the blind material 1 of draining in the horizontal interface of transition region 10 and upstream rockfill area 11, the blind material 1 upstream side splicing sleeve 2 of draining, the opposite side of sleeve pipe 2 connects horizontal drain pipe 3, the opposite side of horizontal drain pipe 3 connects scupper hose 5, the other end of scupper hose 5 is placed in collecting well 6, separately establish vertical drainage pipe 7, vertical drainage pipe 7 lower ends connect 13 and are connected with horizontal drain pipe 3 by curved.
Above-mentioned reverse osmosis drainage system of concrete face rockfill dam in construction period is provided with one-way water stop valve 4 on horizontal drain pipe 3.4 permission dam Nei Shui of one-way water stop valve discharge, and do 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 the dismounting when facilitating the panel construction and panel have been built.
Aforementioned reverse osmosis drainage system, vertical drainage pipe 7 upper ends are connected with another section steel pipe with lengthening vertical drainage pipe 7 by direct 14.
Compared with prior art, the present invention establishes the blind material of draining as dam internal drainage passage in the water in dam tiling, facilitates dam construction, reduces construction and disturbs, and the reduction of erection time, reduces investment outlay; The member less such as the blind material of draining, gutter, one-way water stop valve, transportation and easy for installation flexible, it is little that counter plate weakens scope; Adopt nipple that horizontal drain pipe and sleeve pipe are joined, when panel is built, conveniently dismounting, facilitated slding form operation; The installation of one-way water stop valve not only can move under normal circumstances, also can normally move during the dam body temporary water dash in flood season, can prevent from catchmenting outside the dam, upstream pours in the dam, prevents that outside the dam, mud and rubbish stop up drainage system, external water pressure in the balance dam body voluntarily after flood; The external vertical drainage pipe that adopts sectional to lengthen can satisfy the requirement of the inside and outside hydraulic pressure of balance dam body at times of minute elevation, prevent that in the dam, reverse water pressure power is damaged bedding material, panel and water-stopping system, the later stage adopts the gravity flow cement grouting can conveniently effectively carry out shutoff.The present invention is specially adapted to that river-bed section plinth foundation excavation is dark, upstream apron fills the reverse drainage that the duration is long, dam body need cross the CFRD during Construction of flood dash.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
reverse osmosis drainage system of concrete face rockfill dam in construction period as shown in Figure 1, lay the blind material 1 of draining in the horizontal interface of transition region 10 and upstream rockfill area 1, the blind material 1 upstream side splicing sleeve 2 of draining, the opposite side of sleeve pipe 2 connects the horizontal drain pipe 3 with one-way water stop valve 4, joint screw thread is all established in the outside, two ends of horizontal drainage steel pipe 3, its opposite side connects scupper hose 5, the other end of scupper hose 5 is placed in collecting well 6, separately establish vertical drainage pipe 7, separately establish vertical drainage pipe 7, vertical drainage pipe 7 lower ends connect 13 and are connected with horizontal drain pipe 3 by curved, vertical drainage pipe 7 upper ends are connected to lengthen vertical drainage pipe 7 by direct 14 with another section steel pipe.
