[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0023] Example 1
[0024] See also Figure 1 , shown in the figure is a steel sleeve cofferdam structure with a self-floating empty box, including a steel sleeve cofferdam body 100 and at least one self-floating empty box 200.
[0025] The self-floating empty box 200 is detachably mounted on the outer side of the steel sleeve cofferdam body 100 , so that the steel sleeve cofferdam body 100 floats on the water surface by the buoyancy of the self-floating empty box 200 .
[0026] The steel sleeve cofferdam body 100 adopts a closed steel sleeve cofferdam, which is pre-assembled on the ground. There are two self-floating empty boxes 200, which are symmetrically arranged on the left and right outer sides of the steel sleeve cofferdam body 100. Of course, the number of self-floating empty boxes 200 is not limited to that in this embodiment, and it should be arranged according to the volume and shape of the steel sleeve cofferdam body 100.
[0027] The self-floating empty box 200 adopts a closed-cell foam box structure to ensure that sufficient buoyancy is provided, and at the same time, the self-floating performance will not be affected by water leakage.
[0028] See also Figure 2 Combined with Figure 1 , each self-floating empty box 200 is installed on the outer side of the steel sleeve cofferdam body 100 through three sets of sliding assemblies 300. Specifically, each sliding assembly 300 includes a plurality of I-beam sliders 310, a vertical guide groove 320 and a locking mechanism 330. A plurality of I-beam sliders 310 are arranged at intervals along the vertical direction on the outer side of the self-floating empty box 200 facing the steel sleeve cofferdam body 100, the vertical guide groove 320 is fixedly arranged on the outer side of the steel sleeve cofferdam body 100, and the locking mechanism 330 is arranged in the top of the vertical guide groove 320. During installation, the self-floating empty box 200 is slidably installed in the vertical guide groove 320 on the steel sleeve cofferdam body 100 through a plurality of I-beam sliders 310, and the locking mechanism 330 is used to limit the I-beam slider 310 from being separated from the vertical guide groove 320, so that the self-floating empty box 200 can float vertically along the vertical guide groove 320 on the steel sleeve cofferdam body 100. In this embodiment, the locking mechanism 330 preferably adopts a locking steel rod, which is detachably inserted at the top of the vertical guide groove 320. Of course, the locking device can also adopt other locking structures as long as it can prevent the I-beam slider 310 from escaping from the vertical guide groove 320.
[0029] In order to improve the water-stopping and sealing performance of the steel sleeve cofferdam body 100 , a rubber water-stop strip (not shown in the figure) is provided on the bottom surface of the steel sleeve cofferdam body 100 .
[0030] The surfaces of the steel sleeve cofferdam body 100 and the self-floating empty box 200 are painted with navigation warning patterns of the same eye-catching color or different eye-catching colors (not shown in the figure), which serve as navigation warnings in navigable rivers.
[0031] A steel ladder 110 is provided inside the steel sleeve cofferdam body 100 to facilitate construction workers to carry out construction.
[0032] The working principle of the steel sleeve cofferdam structure with self-floating empty box of the utility model is as follows:
[0033] First, the steel sleeve cofferdam body 100 is assembled on the ground, and the self-floating empty box 200 is installed on the steel sleeve cofferdam body 100. Then, the steel sleeve cofferdam body 100 with the self-floating empty box 200 is placed on the water surface by using a hoisting device.
[0034] The steel sleeve cofferdam body 100 can float on the water surface by relying on the self-floating empty box 200, and then be towed to the designated location by a tugboat; at this time, by pouring water into the self-floating empty box 200 (or removing the self-floating empty box 200), the steel sleeve cofferdam body 100 sinks under the action of gravity and rests on the bottom plate. The steel sleeve cofferdam body 100 is subjected to the water pressure, and the rubber waterstop on the bottom surface of the steel sleeve cofferdam body 100 is compressed and pressed against the bottom plate, so that a water-stop seal is formed between the bottom surface of the steel sleeve cofferdam body 100 and the bottom plate, forming a flood-proof closure, and finally the water in the cofferdam is drained for construction.
[0035] After the construction is completed, the water in the self-floating empty box 200 is drained (or the self-floating empty box 200 is installed on the steel sleeve cofferdam body 100 and water is poured into the self-floating empty box 200, the self-floating empty box 200 sinks to the designated position by its own gravity and is locked, and finally the water in the self-floating empty box 200 is drained), the steel sleeve cofferdam body 100 floats to the water surface by buoyancy, and is towed to the designated position by a tugboat, and finally lifted out of the water by lifting equipment.
[0036] Example 2
[0037] The structure of the steel sleeve cofferdam structure with self-floating empty box in this embodiment is roughly the same as that of the steel sleeve cofferdam structure with self-floating empty box in Example 1, the difference being that: Figure 2 The steel sleeve cofferdam body 100a adopts a semi-closed steel sleeve cofferdam, which is provided with a plurality of steel support members 120a for support to improve the overall stability of the structure.
[0038] Three self-floating empty boxes 200a are arranged at intervals on the outer side surface of the steel sleeve cofferdam body 100a to ensure that the steel sleeve cofferdam body 100a can float stably on the water surface.
[0039] The rubber water stop strip 400a is arranged on the bottom and side of the steel sleeve cofferdam body 100a. When the steel sleeve cofferdam body 100a sinks to the bottom plate, the rubber water stop strip 400a forms a seal between the steel sleeve cofferdam body 100a and the top plate and the pier wall 10.
[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
