This invention provides a device and construction method for the first-phase direct burial construction of inclined gate slots in hydropower station arch dams. The device includes a ladder with several operating platforms and ladders connecting the platforms. The lower end of the ladder is set on a sill, and a pre-embedded support is provided on one side of the ladder. The upper end of the ladder is connected to the pre-embedded support via connectors. A main rail slide installation reference seat, a gate lintel installation reference seat, and a water seal plate installation reference seat are provided on one side of the ladder. During construction, the main rail slide installation reference seat, the gate lintel installation reference seat, and the water seal plate installation reference seat provide installation reference surfaces for the main rail, the gate lintel, and the main rail water seal plate, respectively. This device and method have fewer construction steps, and the installation of the gate slot embedded parts does not occupy the straight-line construction period of the dam concrete pouring, which can greatly accelerate the installation progress. During construction, the entire water sealing section of the gate slot embedded parts is laid out in one go, which can effectively avoid the cumulative error caused by multiple measurements and layouts of the water sealing section.

The invention provides a rapid and safe construction method for upstream and downstream concrete blocks of a rock-fill concrete arch dam, and relates to the technical field of rapid construction of rock-fill concrete arch dams. S2, a formwork system is installed; s3, pouring and initial setting; s4, partial mold removal; s5, rock-fill concrete construction; and S6, circulating construction is conducted.

This invention provides an open-type guide wall pier head, belonging to the field of water conservancy and hydropower engineering technology. The guide wall pier head is designed as a circular arc guide wall pier head, an elliptical guide wall pier head, and a straight guide wall pier head. It also proposes a permissible lateral water level difference Δ in the surface orifice drainage channel. h允 Based on the calculation formulas and combined with the maximum discharge unit width flow rate of the orifice, calculation formulas for the dimensions of various parts of the circular arc guide wall pier, elliptical guide wall pier, and straight guide wall pier were determined, providing effective support for the design of spillway structures in water conservancy and hydropower projects. The determination process does not require hydraulic model testing, offering advantages such as a short design cycle and low cost.

The utility model provides a concrete dam crest hidden type drainage structure system which comprises an upstream concrete dam crest and a downstream concrete dam crest which are respectively provided with a transverse slope, an upstream wave wall is arranged on the end face of the upstream concrete dam crest, and a downstream guardrail is arranged on the end face of the downstream concrete dam crest. A plurality of water inlets and water collecting grooves are formed in the bottom connecting side of the upstream wave wall or the downstream guardrail. Dam crest collected water flows through the water inlets and the water collecting grooves and then flows to the upstream face of the dam through a drainage pipeline in the dam for drainage. The dam crest drainage system has the advantages of being suitable for concrete gravity dams and arch dams and solving the problems that a traditional dam crest drainage system is disordered in arrangement and the dam face is scoured.
