AI Technical Summary

Technical Problem

In the upper chamber of a ground-level or semi-underground gate well, the layout of the hoisting machine room frame structure is difficult, especially the height of the frame columns is limited, resulting in poor seismic performance and failure to meet structural stress requirements, especially when a single-span structure cannot accommodate a large upper chamber.

Method used

The gate hoist room adopts a frame structure with the outer frame columns supported on the top surface of the upper chamber wall of the gate well, and the inner frame columns supported inside the upper chamber well, forming a multi-span structure. This reduces the height of the frame columns and provides a stable foundation, making it suitable for upper chambers of gate wells in oblong, rectangular, or other shapes.

Benefits of technology

This invention provides a new approach to arranging the gate control room above ground level, expands the options for gate well locations and water conveyance system layouts, and features a simple structure that facilitates construction and operation management.

Abstract

The utility model discloses a hoist room framed bent structure of a ground or semi-underground gate shaft upper chamber, which comprises framed bent columns and framed bent beams, the framed bent columns comprise outer framed bent columns on the periphery of the outer side and inner framed bent columns on the inner side, and the framed bent beams are transversely erected among the framed bent columns to form the hoist room framed bent structure. The bottoms of the outer side bent frame columns are supported on the top face of the upper chamber well wall of the gate well, and the inner side bent frame columns are supported in the upper chamber well of the gate well. The utility model can effectively solve the problem that the ground type hoist room framed bent cannot be arranged in an upper room higher than the ground, provides a new way for the arrangement of the hoist room of the ground type upper room, widens the position of a gate shaft and the arrangement scheme selection of a water delivery system, and has the advantages of simple structure, convenience in construction and operation management, and low cost. The method can be widely applied to water conservancy and hydropower engineering.
