Abstract
The utility model relates to a closure building on an open and deep soft foundation river. A bottom protection concrete plate is built on a river bed, and comb piers are built on the bottom protection concrete plate. Comb piers are connected by steel wires, and the comb piers and the steel wires form a stone block fence. The closure building on the open and deep soft foundation river has the benefits as follows: the bottom protection concert plate is built on the river bed, as a result, scouring damage to a river bed soft foundation, caused by high-speed water flow at a closure gap is reduced; the comb piers built on the bottom protection concrete plate reduces the material diameter and loss of special material used in river closure construction, lowers toss intensity and difficulty of closure construction, and meanwhile, utilizes comb overflow fluid state to quickly form backwater in front of a gate, so that a good flow dividing condition is created. If necessary, a comb protection bottom can be effectively combined with a cofferdam anti-seepage system, accordingly, the construction cost is saved, the construction period is shortened, and the problems of high fall, high difficulty in large flow rate deep soft foundation river bed closure construction, long construction time and high construction cost are effectively solved.
Description
Technical field
The utility model relate to a kind of on open deep soft foundation river the building for damming, especially on open plain tract, carry out the building of efficient river closure construction.
Background technology
In Hydraulic and Hydro-Power Engineering is built, the key project that dam project is controlled as hydraulic engineering current, its safe and effective control problem receives much concern always.In order fully to develop water conservancy and hydropower resource, increasing hydraulic engineering is built on deep soft foundation riverbed, especially the final stage power station of Step Hydraulic Engineering, build open plain tract area in more, and riverbed mostly is deep soft overburden, river letdown flow is mainly subject to the impact of power station, upstream letdown flow.River closure construction in this case has the features such as Longkou drop is large, flow velocity is high, construction intensity is large, make river closure construction exist the problems such as and selection of construction machinery large such as large, the special material build of the material flow vector size of damming be difficult, and construction experience in the past and be theoretically still not enough to solve completely the new problem that on deep soft foundation river, dam project occurs.
Summary of the invention
Problem to be solved in the utility model is exactly that a kind of building that can efficiently dam on open deep soft foundation river of being applicable to is provided for above deficiency.Its technical scheme is as follows:
It is on riverbed, to build river bottom protection concrete flat slab, builds broach pier on river bottom protection concrete flat slab.
Broach pier connects with wire rope, makes common formation of broach pier and wire rope block stone grid.
Embedded steel tube in described broach pier, steel wire penetrating steel pipe adopts U-shaped snap ring to connect.
Described U-shaped snap ring comprises dop, deck and snap ring nut, and dop is connected with deck, and snap ring nut connects dop and deck.
The spacing of described broach pier is 2.5m-3.5m.
Compared with prior art, the beneficial effect the utlity model has is:
1, on riverbed, build river bottom protection concrete flat slab, reduce the soft base erosion damage in riverbed that Longkou high-velocity flow causes;
2, on river bottom protection concrete flat slab, build broach pier, the material footpath and the material logistics that reduce the special material thing of river river closure construction use are lost, reduce jettisoning intensity and the difficulty of river closure construction, utilize broach overcurrent fluidised form to form fast the front Yong Shui of lock simultaneously, create good shunting condition.Can, by broach river bottom protection and the effective combination of seepage prevention of cofferdam system, to save construction cost and to shorten the construction period, effectively solve in high drop, large flow deep soft foundation river closure construction and organize the problem that difficulty is large, the engineering time is long, construction cost is high if desired.
3, between broach pier, with wire rope, connect, the common formation of broach pier and wire rope blocked stone grid, to stablize special material thing, the minimizing material logistics vector of jettisoninging Longkou, thus balance Longkou drop.Realize the object of using conventional machinery to carry out rapid intercepting construction, reduce the input of main equipment.
Accompanying drawing explanation
Fig. 1 is the utility model layout plan;
Fig. 2 is the utility model drawing in side sectional elevation;
Fig. 3 is the utility model longitudinal plan;
Fig. 4 is the utility model broach pier longitudinal plan;
Fig. 5 is the utility model wire rope connection diagram.
The specific embodiment
Referring to Fig. 1～5, the utility model is built river bottom protection concrete flat slab 1 on riverbed, and river bottom protection concrete flat slab 1 as shown in Figure 1 or 2, utilizes concrete etc. to be cured riverbed, the soft base erosion damage in riverbed causing to reduce Longkou high-velocity flow; On river bottom protection concrete flat slab 1, build broach pier 2, to reduce material footpath and the material logistics of the special material thing of river river closure construction use, lose, reduce jettisoning intensity and the difficulty of river closure construction, utilize broach overcurrent fluidised form to form fast the front Yong Shui of lock simultaneously, create good shunting condition.
At the interior embedded steel tube 4 of broach pier 2, use wire rope 3 through steel pipe 4, broach pier 2 to be connected, make common formation of broach pier and wire rope block stone grid, to stablize special material thing, the minimizing material logistics vector of jettisoninging Longkou, thus balance Longkou drop.
The termination of wire rope adopts U-shaped snap ring to fix.Described U-shaped snap ring comprises dop 5, deck 6 and snap ring nut 7, and dop 5 is connected with deck 6, and snap ring nut 7 connects dop 5 and deck 6.
During use, wire rope 3 is through the steel pipe 4 in broach pier, and the overlapping dop 5 of putting in two terminations of two wire rope that need are connected, adjusts deck 6, makes it stuck wire rope, and tightening card circular nut 7, fixes the termination of wire rope.
The spacing of described broach pier 2 is set according to the flow velocity of the width of Longkou Kou Men, jettisoning material thing particle diameter and the different sections in Longkou, is taken as 2.5m-3.5m.
In figure, the direction of arrow is water (flow) direction.
