Embodiment 1
[0027] Example 1: The diversion project of the hydropower station has 2 gates and needs to install gate slots, that is, install 4 gate slots. The construction method is as follows figure 1 As shown, after the bottom surface of the gate dam and the bottom sill of the gate sill are poured and formed, according to the predetermined position according to the design and measurement, the door sills are hoisted and installed on the bottom sill of the gate. Climbing gear units such as figure 2 As shown, the door slot installation climbing device includes a vertical truss 1, a door slot part installation part is provided on the outside of the truss, a door slot part storage part is provided on the inside of the truss, and a manipulator is also installed on the truss 3. The manipulator 3 can grab and release the door slot parts, and move between the door slot part installation part and the door slot part storage part; anchor cables and connecting rods are installed between adjacent doo...

The invention discloses a gate dam engineering quick construction method which can be used for constructing a plurality of pairs of gate slots at the same time. The gate dam engineering quick construction method comprises the steps that A, after the bottom faces of the gate slots are constructed, corresponding installation units are arranged on the bottom faces of the gate slots, and fixing connection pieces are arranged between adjacent instillation units; B, the fixing connection pieces are fastened; C, the installation units are adjusted to a casting state; D, first-stage concrete of all gate slots is buried synchronously; E, connection between the gate slots and gate slot installing portions is removed; F, the installation units are lifted by one casting height; G, the lower portions of the installation units are fixedly connected with the installed gate slots, and the position degrees of the instillation units are adjusted; H, operations of the steps B, C, D, F and G are executed repeatedly until the gate slots are constructed to a set height, and gate dam engineering quick casting is achieved. By means of the gate dam engineering quick construction method, the overall construction speed of the gate slots in the concrete casting process is improved, the gate slots can be conveniently installed, and operation time can be conveniently shortened.
Description
technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering construction, and relates to a method and a device for rapid construction of a gate and dam project composed of a plurality of gates and gate slots. Background technique [0002] In water conservancy and hydropower projects, it is necessary to build gates and dams to retain water, and install gates and gate channels to retain water or adjust water flow. The existing gate channel steel structure embedded parts attached to gates usually adopt the method of second-stage concrete installation. This method is easy to guarantee the installation quality, but the construction procedure is complicated, the cycle is long, and the measures to ensure the safety of the operation are complicated, which often restrict the construction of the project. Especially in the gate and dam project with multiple gates, the installation of concrete and gates and their gate slots should be carried...
