Abstract
The invention relates to a pouring self-priming hole PHC tube pile sharp anti-rust cap constructing device, which is connected to the static hydraulic compress machine formed by water tank, multistage eccentric pump, high-pressure transmission tube, clamper, transmission tube, PHC hollow tube pile, high-pressure gas transmission tube and air compressor, with water jet gas jet priming hole, wherein the high-pressure pouring pump via high-pressure pouring tube and three-way tube is connected to the high-pressure water transmission tube; one-way valves are mounted between three-way tube and multistage eccentric pump, three-way tube and high-pressure pouring pump; when the PHC chamber tube pile is fed to the holding layer, and stopping jetting water and gas, starting the high-pressure pouring pump; using high-pressure pouring tube, three-way tube and high-pressure water transmission tube to feed some cement pulp to the pile sharp pump; filling steel pile sharp inner and outer; the forming anti-rust cap packed by cement pulp at the surface of pile sharp, to separate the pile sharp and soil, to resist rust and strengthen foundation, to improve its carrier force.
Description
Technical field the present invention relates to a kind of protection construction equipment and job practices thereof of architecture foundation pile, particularly a kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction equipment and construction technology thereof.
The use foundation pile that the development of background technology pile is a large amount of.And the PHC pile tube is a suitability for industrialized production, and quality is directly perceived, and the pile-formation process quality is easy to guarantee, compare with other concrete filling piles have cheap, short construction period, advantage such as environmental protection and the developing direction of stake for building of becoming.Stake end self-guiding hole PHC tubular pole construction technology is the static(al) hydraulic pressure pile press with band High-Pressure Water and high pressure draught, PHC cavity pile tube is sent into a kind of method of soil layer.The static pressure that relies on the hydraulic pressure pile press merely when pile tube draws the hole by high pressure water transport pipe and high pressure gas pipeline to PHC cavity pile tube bath qi of chong channel ascending adversely when the sand gravel layer pile sinking is obstructed, reduce the pile tube end resistance, and the limit trimming is pressed, and reaches the purpose that penetrates sand gravel layer.But the steel stake of this process using point is owing to be embedded in the soil layer for a long time, is subjected to the immersion of water in soil unavoidably and corrosion, finally influences the bearing capacity of single pile ability of PHC pile tube.Therefore, the problems such as effective stable bond of the corrosion of solution steel stake point, reinforcement stake point and bearing stratum have caused the concern of engineering circle.
Summary of the invention the purpose of this invention is to provide a kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction equipment and construction technology thereof, anti-rust cap can intercept PHC pile tube point and contact with the direct of soil layer, stake point and soil layer are isolated, to reach effect antirust and raising and firm bearing capacity of single pile.
The present invention realizes by following technical proposal: a kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction equipment, and the static(al) hydraulic pressure pile press that draws the hole with the band bath qi of chong channel ascending adversely of being made up of water tank, centrifugal multistage pump multiple centrifugal pump, high pressure water transport pipe, pile chuck, Pile feeder, PHC cavity pile tube, high pressure gas pipeline and air compressor links; High-pressure injection pump is connected with high pressure water transport pipe with tee piece by the high-pressure slip-casting pipe, between tee piece and centrifugal multistage pump multiple centrifugal pump and tee piece and high-pressure injection pump one-way cock is housed.
A kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction technology: when PHC cavity pile tube is delivered to bearing stratum by static pressure, stop to wash by water after the qi of chong channel ascending adversely, start high-pressure injection pump, by high-pressure slip-casting pipe, tee piece and high pressure water transport pipe to a certain amount of cement paste of stake point pumping, steel stake point inside and outside is filled up, the surface of stake point forms the anti-rust cap by the cement paste parcel, and stake point and soil layer are isolated.
Effective effect of the present invention is:
1, by high-pressure slip-casting pipe and high pressure water transport pipe, the cement paste to the pumping of stake end prepares fills up steel stake point inside and outside, the surface of stake point is because the parcel of cement paste, intercept PHC pile tube point and contact with the direct of soil layer, thus the etch of moisture in the blocking-up soil layer, to reach antirust effect.
2, steel stake point can better be combined into one with bearing stratum owing to the effect of cement paste, thereby improves the stability of stake point in soil layer.
3,, thereby reach consolidated subsoil, improve the purpose of bearing capacity of pile foundation because existing crack in the bearing stratum can be effectively filled in the effect of cement paste.
The present invention is further described below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is the schematic diagram of pile tube tip anti-rusting cap construction equipment.
Fig. 2 is the schematic diagram of static(al) hydraulic pressure pile press operation.
Specific embodiment embodiment is shown in Fig. 1-2: a kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction equipment, and the static(al) hydraulic pressure pile press that draws the hole with the band bath qi of chong channel ascending adversely of being made up of water tank (1), centrifugal multistage pump multiple centrifugal pump (2), high pressure water transport pipe (7), pile chuck (8), Pile feeder (9), PHC cavity pile tube (10), high pressure gas pipeline (11) and air compressor (12) links; High-pressure injection pump (3) is connected with high pressure water transport pipe (7) with tee piece (6) by high-pressure slip-casting pipe (4), between tee piece (6) and centrifugal multistage pump multiple centrifugal pump (2) and tee piece (6) and high-pressure injection pump (3) one-way cock (5) is housed.
A kind of after-grouting self-guiding hole PHC tubular pole tip anti-rust cap construction technology, when PHC cavity pile tube is delivered to bearing stratum by static pressure, stop to wash by water after the qi of chong channel ascending adversely, start high-pressure injection pump (3),, to a certain amount of cement paste of stake point pumping steel stake point inside and outside is filled up by high-pressure slip-casting pipe (4), tee piece (6) and high pressure water transport pipe (7), the surface of stake point forms the anti-rust cap by the cement paste parcel, intercept PHC pile tube point and contact, stake point and soil layer are isolated with the direct of soil layer.
