Bayonet binding-type connection method of steel sleeve box blocks and construction method using same

Abstract

The invention provides a bayonet binding-type connection method of steel sleeve box blocks. The method comprises the following steps of: arranging a female bayonet and a male bayonet at a seam of the steel sleeve box blocks and arranging rolling shafts vertical to a wall board of the steel sleeve box at the seam of the steel sleeve box blocks; aligning the female bayonet and the male bayonet in position when the steel sleeve box blocks are assembled, connecting the part above a water surface of the seam into place by using a bolt, and bolting the part below the water surface by using the bolt; then winding and binding the rolling shafts at two sides of the seam by using a length rope; fixing one end of the rope at a rope anchorage point on the wall board of the steel sleeve box, connecting the other end of the rope with a bottle gourd fixed on the wall board of the steel sleeve box, and tightening the rope through an acting force of the bottle gourd; and dismantling the bolt bolted at the part below the water surface and binding and connecting in position to finish seam connection of the blocks. When the steel sleeve box is dismantled, the rope anchored at the rope anchorage point of the steel sleeve box is firstly removed and then pulled out through the acting force of the bottle gourd, then the bolt above the water surface is dismantled, therefore, the binding connection of the bayonets is also removed. Compared with the prior art, the invention effectively solves the dismantling difficulty of the former steel sleeve box under water and in shallow soil, turns the dismantling under water into the dismantling over water after excavation is necessary in shallow water and soil, reduces excavation construction processes and the investment of mechanical equipment and many-fold quickens the construction speed of the sleeve box and the turnover utilization ratio of the sleeve box.

Description

technical field [0001] The invention belongs to the field of bridge foundation construction under water or in shallow soil, and specifically relates to the use of water-proof equipment for the foundation construction of the lower part of the bridge, and more specifically, relates to a steel sleeve box block bayonet binding type connection method and corresponding construction method. Background technique [0002] At present, the assembly and connection methods of steel casing segments or blocks include welding and bolting. The segments processed in blocks are connected into an overall structure by bolting or welding. The biggest difficulty of the above two connection methods is the casing It is difficult to dismantle, especially underwater, where divers need to remove bolts or cut underwater, and the part buried in the soil layer is even more difficult to dismantle, which results in long dismantling time, increased cost and waste of materials, which brings great harm to the ...
