Embodiment Construction

[0013] The structure of the present invention is as figure 1 Shown is an underwater positioning and adjusting device for concrete stacked beams. The positioning device includes a positioning plate 4 on which a plurality of adjusting bolts are fixed. There are three adjusting bolts on the positioning plate 4, and the upper part, the lower part and the middle part of the positioning plate 4 are arranged respectively.

[0014] In the present invention, the positioning plate 4 is made of a steel plate, the size of the positioning steel plate is determined according to the actual situation, the width and the error of the concrete stacking beam are within 10 cm, the positioning plate 4 is connected with the concrete stacking beam 7 through the internal expansion bolt 5, and the adjusting bolt 1 , 2,3 are welded on the positioning plate 4, and the lengthened nut on the adjusting bolt is welded on the base steel plate during welding. When welding, the three nut holes should be aligne...

Abstract

The invention discloses a concrete stoplog underwater positioning regulation device and a stoplog positioning method. A positioning device comprises a positioning plate, and three regulation bolts are fixed on the positioning plate. The three regulation bolts are respectively arranged at the upper part, the lower part and the middle part of the positioning plate. After the concrete stoplog underwater positioning regulation device is arranged on a concrete stoplog, a diver can regulate the distance from the concrete stoplog in a gate slot to a gate slot wall surface through the regulation bolts so as to position the concrete stoplog, greatly shorten the time of underwater construction of the diver and ensure the construction safety of the diver to the maximum extent.

Description

technical field [0001] The invention relates to an underwater positioning and adjusting device for a concrete stacking beam, which is used for precise adjustment and positioning when a concrete stacking beam is installed underwater in a door groove of a hydraulic structure. Background technique [0002] In the heightening project of the Danjiangkou Dam, the water source of the South-to-North Water Diversion Project, the heightening of the overflow dam section includes two parts, namely, the heightening of the gate pier and the heightening of the overflow surface. Due to the limitation of resettlers in the reservoir area, the heightening construction of this part firstly carried out the heightening of the gate pier, and then carried out the heightening construction of the overflow surface. When the overflow weir surface is raised, the concrete pouring needs to be carried out under the condition of anhydrous dry land. Because the initial construction of Danjiangkou is to consi...
