Description
Technical Field
The invention provides an arch-tooth type inverted-arch plunge pool and a construction method, belongs to the technical field of hydraulic and hydroelectric engineering, and is suitable for design and construction of the inverted-arch plunge pool.
Background
With the development of water conservancy and hydropower utilities in China, arch dams become one of the main dam types, the landforms of two sides of a high arch dam hub are generally mountain deep valleys, and many high arch dams are not suitable for arranging flood discharge buildings outside the dam and can only discharge a large amount of flood through the dam body. When the arch dam discharges flood by adopting the dam body, because the range of the nappe is closer to the dam address and the water depth of the downstream riverbed is shallower, in order to avoid the influence of excessive scouring on the safety of the dam foundation and the stability of bank slopes at two banks, a scouring pit is usually pre-dug behind the dam and a secondary dam is arranged to raise the tail water level to form an energy dissipation plunge pool. The plunge pool is a main measure for flood discharge and energy dissipation of the arch dam body, and is a relatively successful engineering measure for flood discharge and energy dissipation arrangement of the high arch dam at present. Most of energy of water flow discharged from the arch dam is consumed in the plunge pool, and strong turbulent water flow generated in the plunge pool can cause washout damage to bedrocks. Therefore, the plunge pool must be lined comprehensively, and can be divided into two types according to the lining structural form of the plunge pool: one is a flat bottom plunge pool and the other is an inverted arch plunge pool.
The bottom plate of the flat-bottom water-cushioned pond is stabilized by mainly depending on the dead weight of the bottom plate and anchoring reinforcing steel bars to keep the bottom plate stable, the rising and floating of the independent bottom plate are used as control conditions, the inverted arch water-cushioned pond utilizes the natural shape of riverbed bedrock to make the bottom plate into an arch shape, and the mechanical property of an arch structure is utilized to transmit jet impact load to an arch base or two banks of mountain bodies, so that the compression resistance of concrete and the overload capacity of the arch structure can be fully exerted, the stability of the single bottom plate under the load action is changed into the integral stability of an inverted arch ring and the arch base, and the integral stability of the bottom plate is greatly improved. Compared with a flat bottom plunge pool, the inverted arch plunge pool adapts to the change rule of the dynamic water load along the way due to the integral stress characteristic of the arch structure, has the advantages of less anchoring quantity, small section, good mechanical structure performance, strong overload capacity, good structure stability, strong terrain adaptability, less excavation quantity, favorability for mountain stability and the like, and is increasingly applied to large project high arch dams. However, for the conventional inverted arch plunge pool, in order to reduce the uplift pressure of the bottom plate, the vertical drain pipe is usually arranged on the bottom plate according to a certain distance, and the bottom of the drain pipe is easily blocked due to the unreasonable arrangement of the inverted filter layer and the influence of underground water seepage in the construction process, so that the design purpose cannot be achieved. In addition, the structural size of the water cushion pond of the high dam is often larger, transverse seams are required to be arranged on the water cushion pond to avoid the damage of temperature stress, the inverted arch water cushion pond bottom plate has the condition that the whole arch can not be formed due to the randomness of load under the action of jet impact load, at a certain moment, when the lifting force acting on a certain single plate has a larger value, random arch is formed, the conventional inverted arch water cushion pond transverse seams are usually in straight seam type, the combined stress between the inverted arch bottom plate blocks is not facilitated, and under the action of repeated load, the phenomenon that the bottom plate blocks fly out of a seat hole and an arch ring is unstable can even occur in serious cases. Meanwhile, when the inverted arch bottom plate forms an arch effect and is integrally stressed, the lifting force on the bottom plate is transmitted to the arch end in the form of axial force, the arch end is stressed, larger arch end thrust is generated, the requirements on concrete of an arch abutment structure and geological conditions of a mountain are higher, the bearing capacity of a base rock of the bottom plate is not fully utilized, anchor bars are usually arranged on the bottom plate to reinforce the bottom plate in engineering, the structural size of the arch abutment is increased, and the stability of the arch abutments at two ends is ensured by adopting the anchor bars or anchor cables, but the corresponding anchoring measures of the bottom plate cannot form the integral structure with the arch abutment and are simultaneously stressed, the construction is inconvenient, and the engineering investment is increased.
