Abstract

This utility model relates to the field of water conservancy and hydropower construction technology, specifically to a support frame for water conservancy and hydropower projects. It includes a base and side support plates on both sides of the base. Two sets of movable rods are rotatably mounted on one side of each side support plate at their ends furthest from the base. Support rods are rotatably mounted on the sides of each side support plate closest to the movable rods. By providing fixed rods and movable rods on the surface of the base, the spacing between the two sets of side support plates can be adjusted according to the width of the pit bottom. The plates can then be quickly fixed with bolts. Simultaneously, a drive assembly at the top of the base can move the two sets of support rods, thereby tilting the side support plates rotatably connected at one end of the two sets of movable rods. This allows for adjustment of the tilt angle of the two sets of side support plates according to the slope of the pit, making operation simpler and providing good practicality and flexibility, thus further improving actual construction efficiency.
