Abstract
The utility model relates to a spiral steel strip-cement diameter increasing pipe pile. The spiral steel strip-cement diameter increasing pipe pile comprises a prestressed pipe pile and a pile pressing paste injection hopper, wherein a spiral steel strip is welded on the outer wall of the prestressed pipe pile; the prestressed pipe pile is pressed into a soil body from the middle part of the pile pressing paste injection hopper; and cement paste or fine aggregate concrete is filled in the pile pressing paste injection hopper, so that the cement paste or the fine aggregate concrete is brought into the soil body through the spiral steel strip in the process of pressing the prestressed pipe pile into the soil body so as to form a steel-cement protective layer coated on the periphery of the prestressed pipe pile. The steel-cement protective layer has an effect of expanding the pipe pile; the pipe pile has the advantages of stronger horizontal shear resistance and vertical bearing force; and pile crack accidents caused by mechanical equipment in piling operation and soil excavation operation can be effectively avoided.
Description
Technical field
The utility model relates to a kind of spirality steel band-cement and increases the footpath pile tube.
Background technology
Advantages such as prestressed reinforcement strong concrete pile tube has the prefabricated production of batch production, and quality control is reliable, and site operation is simple, civilized, and the duration is short, and recruitment is few, and cost is low.But when being applied to this prestressed reinforcement strong concrete pile tube in the soft subgrade soil earth, because the effect of top pile driving equipment and the influence of soil excavation can produce the horizontal shear active force to the pile tube of being driven underground, the quality accident of pile tube fracture takes place easily.
Summary of the invention
The purpose of the utility model is to provide a kind of spirality steel band-cement to increase the footpath pile tube; This pile tube has stronger anti-horizontal shear ability and vertical bearing capacity; Can effectively avoid when piling work and soil excavation operation, an accident that ruptures that is caused by plant equipment takes place.
The technical scheme of the utility model is: a kind of spirality steel band-cement increases the footpath pile tube; Comprise pile for prestressed pipe and piling slip casting bucket; Be welded with the spirality steel band on the outer wall of said pile for prestressed pipe; Port is pressed into the soil body said pile for prestressed pipe from piling slip casting bucket middle part, and in the piling slip casting bucket cement paste or pea gravel concreten is arranged, in order to being pressed at pile for prestressed pipe in the process of the soil body; Through the spirality steel band cement paste or pea gravel concreten are brought in the soil body together, formed and be coated on the peripheral steel-cement topping of pile for prestressed pipe.
In one embodiment, described piling slip casting bucket is provided with vibrating device.
In one embodiment, described spirality steel band is spirality shaped steel, spirality angle steel or spirality steel pipe.
Above-mentioned spirality steel band-cement increases the job practices of footpath pile tube, carries out according to the following steps:
(1) by the width and the pitch of designing requirement, steel are made into the spirality steel band, described steel are shaped steel, angle steel or steel pipe;
(2) spirality steel band cover is received on the pile for prestressed pipe periphery wall, and it is welded on the reservation solder joint on the pile for prestressed pipe periphery wall;
(3) piling slip casting bucket is set earlier on the soil body that will drive piles, and in piling slip casting bucket, pours into cement paste or pea gravel concreten, open and be arranged on the vibrating device on the piling slip casting bucket.
(4) adopt piling equipment that the outlet of pile for prestressed pipe from piling slip casting bucket lower end is pressed into the soil body, simultaneously constantly supplementing water mud or pea gravel concreten in the piling slip casting bucket.
(5) etc. after pile for prestressed pipe is pressed in the soil body fully, remove piling slip casting bucket.
The advantage of the utility model is: this steel-cement topping has the effect that enlarges pile tube; This pile tube has stronger anti-horizontal shear ability and vertical bearing capacity; Can effectively avoid when piling work and soil excavation operation, an accident that ruptures that is caused by plant equipment takes place.The construction technology of the utility model is close with former piling technology; Forming process at steel-cement topping can not increase too much pile driving pressure, adopts common pile driving equipment just can realize; And few to ambient influnence, have applicable to top in the pile for prestressed pipe design of weak soil layer.
Description of drawings
Fig. 1 is the work progress sketch map that the spirality steel band-cement among the embodiment increases the footpath pile tube.
Among the figure: 1-pile for prestressed pipe, 2-piling slip casting bucket, 3-spirality steel band, 4-steel-cement topping, 5-vibrating device, 6-soil body, 7-reservation solder joint.
The specific embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and conjunction with figs., elaborates as follows.
Spirality steel band-the cement of the utility model increases the footpath pile tube; Comprise pile for prestressed pipe 1 and piling slip casting bucket 2; Be welded with spirality steel band 3 on the outer wall of said pile for prestressed pipe 1; Said pile for prestressed pipe 1 is pressed into the soil body 6 from piling slip casting bucket 2 middle part ports, and in the piling slip casting bucket cement paste or pea gravel concreten is arranged, in order to being pressed at pile for prestressed pipe in the process of the soil body; Through the spirality steel band cement paste or pea gravel concreten are brought in the soil body 6 together, be attached to outer cement paste of pile for prestressed pipe or pea gravel concreten and the soil body and form the steel-cement topping 4 that is coated on the pile for prestressed pipe periphery.
In one embodiment, described piling slip casting bucket is provided with vibrating device 5.
In one embodiment, described spirality steel band 3 is spirality shaped steel, spirality angle steel or spirality steel pipe.
Spirality steel band-the cement of the utility model increases the job practices of footpath pile tube, carries out according to the following steps:
(1) by the width and the pitch of designing requirement, steel are made into the spirality steel band, described steel are shaped steel, angle steel or steel pipe;
(2) spirality steel band cover is received on pile for prestressed pipe 1 periphery wall, and it is welded on the reservation solder joint 7 on the pile for prestressed pipe periphery wall;
(3) piling slip casting bucket 2 is set earlier on the soil body that will drive piles 6, and in piling slip casting bucket, pours into cement paste or pea gravel concreten, open and be arranged on the vibrating device 5 on the piling slip casting bucket.
(4) adopt piling equipment that the outlet of pile for prestressed pipe from piling slip casting bucket lower end is pressed into the soil body, simultaneously constantly supplementing water mud or pea gravel concreten in the piling slip casting bucket.
(5) etc. after pile for prestressed pipe is pressed in the soil body fully, remove piling slip casting bucket.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
