Description
Technical field
The present invention relates to waterworks or draw water pump house construction phase water intake facilities field more particularly to a kind of invigorated rivers
Water intake facilities and its integral installation construction method in bed.
Background technique
Water intake facilities refer generally to water intake, aqueduct and dock facility with the horn mouth of water intake, aqueduct joint,
Construction and installation are always interim one of the most critical processes of waterworks construction.With construction safety risk big, environmental protection be difficult to it is up to standard, apply
The problem that the work period is long and operating expenses is high.In the prior art, those skilled in the art are used to solve above-mentioned technical problem
Scheme be to be generally divided into fording operation and land and water to convert two kinds of dry operation method, the installation for water intake facilities.It paddles work
Pipeline transportation by driving to set waters, water filling are sunk down into commitment positions, adopted by the method that transportation by driving sinking installation is generallyd use when industry, segmentation
Implemented with ship, raft plate ship auxiliary.Land and water converts that dry operation is relatively easy to be illustrated, be exactly using the modes such as pipe laying, drainage into
The guidance of row water flow forms dry ground condition and carries out operation after then the modes such as cofferdam, caisson are drawn water.But land and water conversion dry method is made
Industry is suitable for that water is shallow, flow velocity is slower, innavigable operating condition, transportation by driving when fording operation sink installation premise be must point
Section, stream are slow, navigation requires under low operating condition.
As (belonging to Drainage Area of Jinsha River korneforos heart cruising ground in Jinsha jiang River away from bank 20m~80m, depth of water 9m, flow velocity 6m/s
Domain, level-one water source, mandarin sturgeon protection zone) in installation water intake facilities (specifically: the aqueduct of 1420 × 14mm of double joint φ
(wherein underwater portion mileage is K0+000~K0+055) and long 12.4m, the ship type steel construction water intake of wide 3.6m, high 5.9m
(36.9 tons of its total weight)), and the operating condition of navigation condition must be reserved, using the method safety risk of segmentation floating clouds sinking installation
It is huge, thus research and develop it is a kind of suitable in torrent riverbed water intake facilities install new process, new method, taken in torrent riverbed
Effective measure solves the installation question of water intake facilities in terms of duration, cost-effectiveness, safe mass control, is one
It is worth the project of exploratory development.
Summary of the invention
The purpose of the present invention takes effective measure in torrent riverbed, reduces the water flow reduction of speed in construction area,
Diving under water powder charge is avoided, the installation question of water intake facilities is solved.
The present invention is in order to solve the above technical problems, provide the following technical solutions:
