Embodiment Construction

[0010] See the accompanying drawings, the underwater piling device includes: a sealing sleeve 1 whose inner diameter is larger than the outer diameter of the conduit 4 and whose bottom is conical. The sealing sleeve 1 is provided with an inner flange 2 and a rubber pad 3. There are two steel wire rope sleeves 8 on the outer wall of the sealing sleeve, a bolt 6 connected to the steel wire rope 5 and a latch sleeve 7 on the conduit 4. The tapered bottom of the sealing sleeve 1 is provided with a recovery steel wire rope 9 , Recovery steel wire rope 9 is connected on the latch 6.

[0011] During use, the sealing sleeve 1 is installed on the lower opening of the conduit 4, the latch 6 is installed in the latch sleeve 7 on the conduit 4, the steel wire rope sleeve 8 on the outer wall of the sealing sleeve 1 is buckled on the latch 6, and the steel wire rope sleeve 8 is adjusted. length, so that the inner flange 2 of the sealing sleeve 1 is tight against the bottom opening of the co...

Abstract

The invention discloses an underwater pile extension device which comprises a plugging sleeve with the inside diameter more than the outside diameter and the tapered bottom, wherein, the plugging sleeve is provided with a flange and a rubber mat. A locking device is arranged between the plugging sleeve and a pipe, and a reclaimed rope is arranged at the tapered bottom of the plugging sleeve; the locking device is composed of a loop on the outside wall of the plugging sleeve, a plug connected with a rope and a plug sleeve on the pipe. The invention ensures that the pipe can smoothly be inserted into original concrete by arranging the plugging sleeve into the bottom port of the pipe. By the control of the locking device, the pipe and the plugging sleeve can be disconnected and reclaimed to ensure that the new concrete can directly integrate with the original concrete well, the continuity of the concrete can be maintained and concrete quality can not be affected.

Description

technical field [0001] The invention belongs to a device for pouring underwater concrete by a conduit method, in particular to an underwater pile connection device. Background technique [0002] At present, when performing underwater concrete pouring by the conduit method, it is easy to interrupt the pouring of concrete due to reasons such as conduits entering water, blocking pipes, or improper operation, so that the conduits are all pulled out of the concrete. After this kind of problem occurs, if the concrete is re-cast with pressure water, there will be interlayers between the old and new concrete due to the presence of concrete laitance, etc., forming a "broken pile". The quality of such concrete entities does not meet the design and specification requirements. . However, the handling of broken piles is extremely difficult, expensive, or even impossible to handle, and additional piles need to be repaired. At present, there is no method to properly solve this problem bot...
