Abstract
The present invention relates to a plum blossom stud device which can increase soil bearing capacity and resist and prevent foundations from subsiding. The present invention comprises a spiral pile 2 and a technology which filled cement in a pile body. The technology, foundations subside when meet soft foundations, which can not be solved by pile driving and pile filling has the functions of quick operation and convenient construction.
Description
The invention belongs to the field of building foundation or other foundation piles, it is specially adapted to the soft foundation of various bad grounds.
Existing various stake, all produce the phenomenon that foundation pile sinks in being arranged at soft foundation the time as preformed pile, castinplace pile, sand pile, lime stake etc., if improve the bearing capacity of foundation pile in soft foundation, then Zhuan construction period is long, investment is big, and its effect is not remarkable.
The object of the present invention is to provide a kind of foundation pile device and job practices thereof, utilize this device and job practices thereof can significantly improve the bearing capacity of foundation pile, thereby reduce the deflection on basis.
The present invention includes a vertical direction and be located at base center stake in the ground, this base center stake is provided with the anchor ear chuck, around the stake stake of base center, be provided with oblique stake, this logical anchor ear chuck in oblique stake top links to each other with the base center stake, thereby its bottom angled is inserted the effect of playing supporting base center stake in the ground downwards.
Above-mentioned described oblique stake can adopt symmetry or asymmetric to be arranged in around the stake of base center, as quincunx for single or many.
In order to realize the foundation pile device of the invention described above, can adopt following job practices, its step comprises at first straight down the base center stake is arranged in the ground, the stake predetermined position is provided with the anchor ear chuck in the base center, the stake pipe that the bottom is had the spiral cutter head screws in the ground from anchor ear chuck vicinity along oblique direction down, use jacking device compaction pile pipe after waiting to reach the precalculated position, thereafter mentioning a pipe again fixes on the anchor ear chuck in the stake of base center to pre-determined constant, the cement paste scene for preparing is poured in the pipe, cement paste is through the stake wall of the lumen flows to a soil body cavity that the spiral cutter head outside compacting in advance of pipe bottom forms from stake pipe bottom injected hole in, in whole stake pipe, fill cement paste, form oblique screw pile.
According to the needs of engineering, can around the stake of base center, form many oblique screw piles.
The invention has the advantages that the raising by a relatively large margin that utilizes less investment and realize the foundation pile bearing capacity, and easy construction, promptly can be used for newly-built basis and also can be used for repairing the basis.
The present invention is further described below in conjunction with embodiment shown in the drawings.
Fig. 1 is the elevational schematic view of foundation pile device of the present invention.
Fig. 2 is the floor map of foundation pile device of the present invention.
As shown in Figure 1, the foundation pile device comprises a base center stake 4, want building constructure 1 above it, be provided with an anchor ear chuck 3 at an upper portion thereof, anchor ear chuck 3 is fixed with symmetrically arranged oblique screw pile 2, this oblique screw pile 2 is to form like this, near anchor ear chuck 3, stake pipe 7 is screwed in the ground along oblique direction down, because stake pipe 7 bottoms have helical blade, so in construction, be easy to utilize machinery or manually tilt to insert stake pipe 7 in the ground, adopt jacking device compaction pile pipe 7 afterwards, to form the soil body hole 8 of stake pipe 7 bottoms, again predetermined fixed being mentioned on this pipe top fixes on the anchor ear chuck 3 in the base center stake 4, at this moment just can manage the cement paste 6 that perfusion is prepared by sand and cement in advance in 7 to stake, above-mentioned soil body hole 8 is filled with in injected hole 9 outflows that this cement paste 6 is managed 7 bottoms from stake, just formed a big termination in the end of oblique screw pile 2 like this, increased the anti-corrosion capability of helical blade and the bearing capacity of whole foundation pile, above-mentioned cement paste 6 is poured into stake pipe 7 fill with till.
As shown in Figure 2, formed oblique screw pile 2 can be by the requirement of engineering symmetric arrangement, and is provided with many, and its shape, size, gradient can be determined in construction.
Claims (5)
1, a kind of foundation pile device, it comprises that a vertical direction is located at the base center stake 4 in the ground, this base center stake 4 is provided with anchor ear chuck 3, around base center stake 4, be provided with oblique stake 2, these oblique stake 2 tops link to each other with base center stake 4 by anchor ear chuck 3, thereby its bottom angled is inserted the effect of playing supporting base center stake 4 in the ground downwards.
2, device according to claim 1 is characterized in that described oblique stake 2 is for single.
3, device according to claim 1 is characterized in that described oblique stake 2 comprises that many are arranged in base center stake 4 stake on every side.
