Abstract
The utility model comprises a conduit, an outer sleeve pipe and an inner sleeve pipe. The surface of the inner side wall of the outer sleeve pipe is welded with a plurality of angle iron intervals. The utility model is characterized in that the position between the inner sleeve pipe and the outer sleeve pipe is provided with more than one gas-filled type rubber ring approaching an opening of the bottom end of the outer sleeve pipe, and the rubber ring is connected with a gas pipe which can be extended to the ground to connect an air compressor; after the rubber ring is filled with the gas, the rubber ring can expand and clog the position between the inner sleeve pipe and the outer sleeve pipe. Thus, the reverse overflow cement can not penetrate into the clearance of the inner sleeve pipe and the outer sleeve pipe. The utility model can achieve the effect of reducing frictional force when the outer sleeve pipe is pulled.
Description
A kind of partition structure of double mould-pipe base pile belongs to technical field of buildings.
Traditional double mould-pipe base pile structure, its only between inside and outside sleeve pipe appropriate location support with angle bar and isolate, with crack between guaranteeing therebetween, but, when so being configured in grouting, its cement grout is bound to overflow into by up pouring in down a chimney at the bottom of the hole between the inside and outside sleeve pipe in the crack, especially suitable distance is welded with the isolation angle bar in outer tube, and the pressure of cement and factor such as solidify, all can cause outer tube when dial removing, to produce great friction, be difficult to dial this outer tube, not only time-consuming taking a lot of work, increase cost, more can destroy sleeve pipe sometimes and maybe its group can't be risen.
The purpose of this utility model provide a kind of between inside and outside sleeve pipe nearly outer tube bottom end opening inner edge place be provided with the partition structure of double mould-pipe base pile of the elastic tape of an above inflatable.
Scheme of the present utility model comprises conduit, outer tube and inner sleeve, the outer tube interior sidewall surface suitable be welded with several angle bar at interval, its inventive point is: be provided with the air filling type elastic tape more than at the bottom end opening inner edge place of nearly outer tube between the inside and outside sleeve pipe, this elastic tape is connected with a tracheae and may extend into ground and be connected with air compressor; When elastic tape is filled with air and expands, block between inside and outside sleeve pipe, make down the cement that overflows can not infiltrate crack between the inside and outside sleeve pipe.
The utility model has the advantages that, because before grouting, the mat air compressor is given the inflation of the elastic tape of being located at nearly outer tube bottom end opening inner edge place between the inside and outside sleeve pipe, elastic tape is expanded and block closely between inside and outside sleeve pipe, cause the cement that up falls to overflow by bottom, Chinese toon hole in when grouting and can not infiltrate between the inside and outside sleeve pipe between the crack, reach the effect that reduces friction when removing outer tube dialling.
The utility model has following accompanying drawing, and accompanying drawing is briefly explained.
Accompanying drawing 1 is a constitutional diagram of the present utility model.
Accompanying drawing 2 is to intercept the position partial sectional view.
Label declaration in the accompanying drawing is as follows:
1 Chinese toon hole, 2 conduits
3 outer tubes, 4 inner sleeves
5 angle bar are 6 elastic tapes at interval
7 tracheaes, 8 air compressors
See also accompanying drawing 1,2, comprise conduit 2, outer tube 3 and inner sleeve 4 among the figure, conduit 2 is to insert the boring direction of Chun Kou with avalanche prevention mill and the two sleeve pipes of guiding when just being excavated to the 2-3 meter in this Chinese toon hole 1, outer tube 3 interior sidewall surface then suitable be welded with several angle bar at interval 5, to support and to isolate distance between itself and the inner sleeve 4; Its principal character is:
Air filling type elastic tape 6 more than the bottom end opening inner edge of nearly outer tube 3 is provided with outside one between inside and outside sleeve pipe (among this figure be embodiment with two) then is connected with a tracheae 7 and may extend on the ground and be connected with air compressor 8 on this elastic tape 6.
More than structure system is fixed on the elastic tape 6 of unaerated 5 belows, angle bar interval of the nearly bottom opening of outer tube 3 inner edges earlier, treat that again this pair sleeve pipe gets into location desire grouting preceding (as shown in Figure 1), mat air compressor 8 is squeezed into air in the elastic tape 6 by the tracheae 7 that extends to ground, make elastic tape 6 expansions and closely block asking in inner sleeve 4 and outer tube 3, the cement that is up fallen to overflow by hole Chinese toon 1 bottom in when grouting causes in can not infiltrate, in the crack and by being completely cut off outside outer tube 3, and then can reach dialling and have the effect that reduces friction when removing outer tube 3 between the outer tube.
Claims (1)
1, a kind of partition structure of double mould-pipe base pile, comprise conduit (2), outer tube (3) and inner sleeve (4), outer tube (3) interior sidewall surface suitable be welded with several angle bar (5) at interval, it is characterized in that: be provided with the air filling type elastic tape (6) more than at the bottom end opening inner edge place of nearly outer tube (3) between the inside and outside sleeve pipe, this elastic tape (6) is connected with a tracheae (7) and may extend into ground and be connected with air compressor (8).
