The present invention discloses a vertical and horizontal bidirectional constrained anchor pile support structure, comprising a plurality of anti-sliding piles arranged in parallel and vertically or obliquely, wherein a top beam and a corbel are arranged on the top of the anti-sliding piles, and a pile baffle is arranged between two adjacent anti-sliding piles, and a first anchor cable is arranged on the top of the corbel, and one end of the first anchor cable is connected to the top of the corbel through a first anchor head, and an anchor cable steering device is arranged on the corbel, and one end of the anchor cable steering device is fixedly connected to one end of the first anchor cable, and the other end of the anchor cable steering device is fixedly connected to one end of the second anchor cable, and the other end of the second anchor cable is fixed to the front side of the anti-sliding pile through the second anchor head. The anchor cable provides vertical and horizontal constraints through the anchor cable steering device, thereby realizing the support function of the anchor pile, and the fulcrum of the first anchor cable and the steering device acts on the corbel vertical load, providing an anti-overturning bending moment for the top of the anti-sliding pile, which can strictly control the deformation of the pile top, reduce the support cost, and improve the reliability of the support structure system, which is convenient for promotion and application.

The utility model discloses a multistage embedded pile and frame pile combined structure for reinforcing a landslide, which comprises at least four rows of slide-resistant piles, the at least four rows of slide-resistant piles comprise at least two rows of single embedded piles, at least two rows of portal type embedded piles and at least two rows of frame type embedded piles which are sequentially arranged along the slope direction of a slope surface from high to low, and the frame type embedded piles are arranged along the slope direction of the slope surface from high to low. The first pile body and the second pile body are sequentially arranged from high to low in the slope direction of the slope surface, and the first beam body is connected with the first pile body and the second pile body. The third pile body and the fourth pile body are sequentially arranged from high to low in the slope direction of the slope surface, and the second beam bodies are connected with the third pile body and the fourth pile body and are arranged at intervals from top to bottom. A combined system formed by the reinforcing structure and the slope body is large in overall rigidity, high in deformation resistance and high in anti-sliding bearing capacity, the safety and stability requirements of a long sliding surface and a high-thrust landslide after reinforcement can be met, and deformation of the slope body can be effectively limited.

The utility model belongs to the technical field of steam turbines, and particularly relates to a steam turbine through-flow structure which comprises an outer cylinder, a steam exhaust cylinder and a rotating shaft, a steam inlet chamber is arranged in the outer cylinder, a front shaft sealing body is arranged between the rotating shaft and the outer cylinder, a steam exhaust end is arranged on the outer side of the steam exhaust cylinder, a static blade is arranged on the rotating shaft, a partition plate sleeve is arranged on the static blade, and a movable blade is arranged on the rotating shaft. The static blade comprises an ejection piece, a hinge, an open groove, an ejection plate, a rotating shaft, an ejection spring and a stress rod. Through the ejection piece, the hinge, the jacking plate, the rotating shaft, the jacking spring and the stress rod, the pressure borne by the stationary blade is reduced, the stationary blade is strengthened through the stress rod, the output power of the steam turbine can be improved by increasing the input pressure of external steam, meanwhile, the stability and the pressure bearing effect of the stationary blade are guaranteed, and the service life of the steam turbine is prolonged. The stationary blades can be self-adaptive according to the size of the passing steam, so that the pressure of the steam ejected between the stationary blades is always ensured to be sufficient, and the attenuation efficiency in the subsequent steam conveying process is reduced.

The present invention belongs to the technical field of prefabricated buildings, and particularly relates to a prefabricated concrete hollow wall anti-expansion formwork device and construction process. The device includes a hollow wall and a pressure beam assembly, wherein the pressure beam assembly includes a plurality of bottom pressure beams, and the plurality of bottom pressure beams are arranged on the outside of the prefabricated wall panels of the hollow wall, and are connected to the tension bolt group of the hollow wall. The bottom pressure beam is an I-shaped structure, including a flange plate I, a web plate and a flange plate II, wherein the flange plate I and the flange plate II are arranged in parallel, and the web plate is vertically connected between the flange plate I and the flange plate II; the web plate is parallel to the prefabricated wall panel, and a plurality of connection holes for connecting with the tension bolt group are provided on the web plate in the length direction. The present invention requires less equipment investment, is quick to take effect, reduces unnecessary reinforcement in the cavity, and reduces product cost.
