The utility model belongs to the technical field of the design of the opening and closing mechanism of the stoplog gate, and particularly relates to a transfer device for the leaves of the stoplog gate. The utility model includes a water inlet hole, a stoplog gate storage area, a door machine track and a one-way door machine, and a trolley track is arranged on the side area of the water inlet hole and perpendicularly intersects with the door machine track, a transfer trolley is installed on the trolley track, and the transfer trolley is equipped with a power mechanism for driving the trolley to reciprocate along the trolley track; a load platform is arranged on the transfer trolley through a lifting mechanism, and the load platform is used for transferring the stoplog gate leaves; the trolley track has a first end arranged close to the door machine track and a second end arranged away from the door machine track, the stoplog gate storage area is arranged at the second end of the trolley track, and the stoplog gate storage area is arranged with storage platforms for storing the stoplog gate leaves on both sides of the trolley track. The utility model can conveniently realize the transfer of the stoplog gate leaves in the vertical direction of the one-way door machine running track.

The utility model discloses a kind of underground station pile wall composite structures, including underground station structure and the foundation pit enclosure stake of being set in the outer side of underground station structure, the sidewall bottom joist of being equipped with in the lower side of underground station structure two sides, transverse reserved reinforcement is equipped in the foundation pit enclosure stake, first connection reinforcement is correspondingly equipped in the sidewall bottom joist, and the foundation pit enclosure stake is close to the side of underground station structure and is equipped with the reinforcement connection component for the transverse reserved reinforcement and the first connection reinforcement connection. The utility model analysis foundation pit enclosure stake base is used as the composite structure of underground station pile foundation, realizes enclosure foundation pit engineering and underground station structure intensive sharing, solves later period enclosure stake waste problem, effectively improves resource utilization efficiency, simultaneously reduces underground station structure outer wall thickness and reinforcement, saves engineering investment.

This utility model provides a fully gravity-fed drainage structure for a switchyard, belonging to the field of water conservancy and hydropower technology. It includes a switchyard site, and a relay protection building and a GIS building respectively installed on top of the site. Both the relay protection building and the GIS building have basements for cable laying at their bases. The two basements are connected by a cable corridor. A site drainage ditch is installed around the outer perimeter of the switchyard site, and an indoor drainage ditch is installed around the inner perimeter of the basements. A corridor drainage ditch is installed inside the cable corridor, and a collection well is also installed in the basement of the GIS building. This utility model, through its gravity-fed and centralized drainage design, solves the problem of flooding caused by water pumps used for drainage when indoor water seepage occurs, especially in cases of pump equipment failure or power outage.

This utility model belongs to the field of engineering construction technology, specifically relating to a tie rod device for enhancing the stability of temporary lattice columns in foundation pits. It includes: a support structure with pre-reserved tie rod connecting steel bars inside; two lattice columns installed in the foundation pit, each with a lattice column foundation at its bottom; channel steel located between the two lattice columns, with both ends welded and fixed to the corresponding connecting plates on the lattice columns; multiple tie rods installed in the foundation pit, with both ends connected to the support structure and the lattice columns; and turnbuckles on the tie rods, with the end closest to the support structure welded and fixed to the pre-reserved tie rod connecting steel bars. This utility model utilizes tie rods to connect the lattice columns and the support structure, effectively solving the problem of excessively long internal support calculations that fail to meet stability calculation requirements. It also offers good economic benefits and has promising market application prospects.
