Abstract
The utility model discloses an underwater pile extension device which comprises a shut off sleeve, wherein the inner diameter of the shut off sleeve is larger than the outer diameter of a canal and the bottom part is conical; an inner flange and a rubber cushion are arranged in the shut off sleeve; a locking device is arranged between the shut off sleeve and the canal; the conical bottom part of the shut off sleeve is provided with a recycling rope; and the locking device comprises a rope sleeve arranged on the outer wall of the shut off sleeve, a pin connected with the rope and a pin sleeve arranged on the canal. The utility model leads the canal to be successfully inserted into the original concrete again by mounting the shut off sleeve at the bottom opening of the canal. The shut off sleeve can be separated with the canal and can be recycled by controlling the locking device, thus leading newly grouted concrete to be directly and excellently combined with the original concrete, thus maintaining the continuity of the concrete and ensuring the quality of the concrete not to be affected .
Description
Technical field
The utility model belongs to the device that tremie method is built underwater concrete, is specifically related to a kind of pile extension under water device.
Background technology
At present, carrying out tremie method underwater concrete when perfusion, owing to water injection through pipe, plugging or misoperation conduit all extracted reason such as concrete easily and make concrete building be forced to interrupt.After this problem occurring, if carry out the setting-out concreting again, then will form " broken pile " owing to existing concrete laitance etc. interlayer to occur between the new-old concrete, such concrete solid quality is not satisfy design and code requirement.And the processing of broken pile is extremely difficult, and is costly, even can't handle, and needs piling separately, and present home and abroad does not still have any method and can properly settle this problem.
The utility model content
The purpose of this utility model is to provide a kind of pile extension under water device, to solve the continuity problem of having no progeny in the underwater concreting between the new-old concrete that carries out underwater concreting again.
The technical scheme that realizes the utility model purpose is:
The pile extension under water device comprises an internal diameter greater than the tapered shutoff cover of conduit external diameter and bottom, is provided with inner flange and rubber pad in the shutoff cover, is provided with locking device between shutoff cover and the conduit, and the conical lower portion of shutoff cover is provided with and reclaims rope; Described locking device is formed by being located at rope sling, the latch that is connected with rope on the shutoff cover outer wall and being located at supravasal pin bushing.
Described recovery rope can be connected on the latch.
The utility model is installed the shutoff cover by mouth at the bottom of conduit, makes conduit to insert smoothly in the former concrete again.By the control locking device, can and reclaim shutoff cover and conduit disengaging, make the direct and former concrete good combination of concrete of new perfusion, keep concrete continuity, guarantee that concrete quality is not affected.The utility model can thoroughly solve underwater concrete interrupt building after, a difficult problem of building again avoid occurring the quality problems such as broken pile that cause owing to reasons such as conduit is extracted, pluggings, and this apparatus structure is simple, easy construction.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
See accompanying drawing, the pile extension under water device comprises: an internal diameter is greater than the tapered shutoff cover 1 of conduit 4 external diameters and bottom, be provided with inner flange 2 and rubber pad 3 in the shutoff cover 1, shutoff cover 1 is outer to be provided with two and to form by being located at steel wire loop 8, latch 6 that is connected with wire rope 5 on the shutoff cover outer wall and the pin bushing 7 that is located on the conduit 4, the conical lower portion of shutoff cover 1 is provided with one and reclaims wire rope 9, reclaims wire rope 9 and is connected on the latch 6.
During use, shutoff cover 1 is contained in the end opening of conduit 4, latch 6 is installed in the pin bushing 7 on conduit 4, the steel wire loop 8 that shutoff is overlapped on 1 outer wall is buckled on the latch 6, regulate the length of steel wire loop 8, make the inner flange 2 of shutoff cover 1 hold out against 4 end of conduit mouth, and utilize rubber pad 3 sealings on the inner flange 2.After shutoff cover 1 installs, check sealing, conduit 4 is transferred to former concrete surface together with shutoff cover 1, in conduit 4, fill concrete, shutoff cover 1 and conduit 4 end openings together insert appropriate depth in the former concrete, promote the wire rope 5 that connects latch 6, to extract in the pin bushing 7 of latch 6 from the conduit 4, break away from 4 end of conduit mouth under the concrete pressure of shutoff cover 1 in conduit 4, tremie method is normally built underwater concrete routinely, when promoting latch 6, shutoff cover 1 is together reclaimed by reclaiming wire rope 9.
Be not connected on the latch 6 if reclaim wire rope, then will promote separately and reclaim wire rope 9, shutoff cover 1 is reclaimed.
Claims (2)
1, a kind of pile extension under water device is characterized in that comprising an internal diameter greater than the tapered shutoff cover of conduit external diameter and bottom, is provided with inner flange and rubber pad in the shutoff cover, is provided with locking device between shutoff cover and the conduit, and the conical lower portion of shutoff cover is provided with and reclaims rope; Described locking device is formed by being located at rope sling, the latch that is connected with rope on the shutoff cover outer wall and being located at supravasal pin bushing.
2, pile extension under water device according to claim 1 is characterized in that described recovery rope is connected on the latch.
