Of course, this application river bed formula factory building body 1 for including manger 13 and arrange the factory building 14 in this manger 13 downstream side, manger 13 with factory building 14 all through the 5 crimping of bottom plate on river bed basis 3, factory building 14 be power station formula factory building.
In summary, the above structure provided by the present application also has the following advantages and features,
the length of the cut surface of the sliding surface of the bottom of the plant can be effectively prolonged through the tail water structure extending structure, namely the tail water structure extending structure and the tail water structure bottom plate are poured to form an integral structure, the sliding resistance is improved, and therefore the deep anti-sliding stability of the riverbed type anti-sliding plant is effectively improved. When not setting up this structure, the deep sliding mode of factory building basis is: the plant foundation slides along the weak sliding surface, the downstream is cut from the point 3 to the point 4, the sliding resistance surface is a connecting line surface between the point 3 and the point 4, and the length of the sliding resistance surface is the distance between the point 3 and the point 4.

The tail water structure extension structure is a measure which is simple in construction, small in investment increase and capable of effectively improving the stability and safety factor of deep anti-skidding.
Example one
This application is through setting up factory building bottom plate extension structure, and the overall structure that forms is pour simultaneously with the factory building bottom plate to bottom plate extension structure promptly, utilizes the water at factory building bottom plate extension structure top to increase the vertical power of factory building bottom plate, and the water at 1 to 2 tops of point promptly is heavy, to the cling compound of factory building basal plane stably saying, the effect is equivalent to utilizing water to replace partial concrete, can effectively improve the cling compound stability of factory building base plane. ' Qiyi
Because the structural feature of riverbed formula factory building tailrace, the factory building downstream side excavation is great usually, and the factory building downstream side can be used for preventing deep anti-skidding stable rock mass thickness is less usually. When a soft structural surface with a slow inclination angle exists in a plant foundation, the deep anti-sliding stability of the riverbed type plant is difficult to meet the standard requirement, and the plant has the risk of deep instability. Meanwhile, due to the existence of the tail water channel, the slip resistance of the downstream side of the factory building cannot be improved by increasing the weight, and the problem that the deep-layer skid resistance of the factory building is stable is solved by a conventional method, the dead weight of the factory building is generally increased or the mechanical parameters of a foundation slip surface are improved by performing foundation treatment, so that the problem is solved by increasing the dead weight of the factory building or adopting grooving replacement, pile foundation and other methods, which usually needs to spend a large investment cost, and the method is not the best solution in terms of the economy of the project.
