Embodiment Construction
[0046] The present invention is described in further detail below by embodiment, and embodiment is only used for illustrating the present invention, does not limit the scope of the present invention.
[0047] like Figure 1-9 The hoisting method shown in a super-large arc door opening includes the following steps: 1) measuring the effective space in the opening and setting out the installation reference; using a total station, theodolite, steel ruler, steel tape, etc. to measure An instrument tool to measure the space of the flood tunnel lock chamber. Based on the original datum points reserved for civil engineering, survey and draw the arc gate slot centerline, installation longitudinal centerline, bottom sill mileage elevation, support hinge installation mileage elevation span and slope, and the installation of the hoisting cylinder on the hoisting platform. Mileage, elevation, span, etc., and leave detection and control reference points on the permanent foundations such as...

The invention belongs to the technical field of mounting of hydraulic metal structures, and relates to a hoisting operation method for mounting and constructing an ultra-large arc gate in a flood discharge tunnel. The hoisting operation method for mounting and constructing the ultra-large arc gate in the flood discharge tunnel comprises the following steps: embedding anchor hooks at suitable positions such as a tunnel top, a position below a supporting beam of a lifting platform and a side wall as fixed hoisting points; arranging a pulley block, a lifting chain block, a winch and the like as means assisting in hoisting to cooperate with a truck crane for hoisting; and taking the truck crane as a main crane and taking the winch and the lifting chain block as auxiliary tools, reversely transporting mounting pieces into the tunnel by a self-made transport trolley, and mounting, adjusting and aligning an articulated gate shoe by a self-made support frame after the articulated gate shoe isarranged in place. Hoisting and mounting construction is carried out by fully using the effective space in a gate room and existing resources of a construction site, the construction period can be shortened, construction safety is ensured, and requirements such as construction quality are met.
Description
technical field [0001] The invention belongs to the technical field of hydraulic metal structure installation, and relates to a hoisting operation method for installing and constructing a super large arc gate in a flood discharge tunnel. Background technique [0002] Arc gates are often used for surface hole overflow of hydropower stations, or submerged hole flood discharge. The water retaining surface of the door leaf is arc-shaped, the back of the door leaf is connected with the hinge device through the support arm, and the hinge seat of the support hinge is anchored on the side wall concrete structure. The hinge device is composed of hinge, hinge shaft, hinge seat and so on. The opening and closing equipment is installed above the door leaf or support arm, and the door body is pulled to rotate around the hinge axis to realize the opening and closing of the door body. On the bottom, side, and top of the door leaf, steel components such as the bottom sill, arc-shaped side...
