Description
Technical field
The present invention relates to building engineering fields, and in particular to a kind of new type cement soil composite pile.
Background technique
Composite pile is that ground field proposes a kind of new pile-type in recent years, solves stratum limitation, the work of traditional pile-type
Problems, the ways such as skill backwardness, project cost height are soil cement stud of first constructing, certain after the outer pile driving construction of soil cement
Construction core stake in time, forms the composite pile of external flexible, internal rigid.The construction method of soil cement stud is revolved frequently with high pressure
Spray, cement mixing or mixing jet-grouting etc. use the methods of to sink to, drill or hammer after pile and are inserted into core stake, formed multiple
Stake is closed, although compound pile installation and construction method type are many, most pile-type is by the otherness on stratum, the condensation of soil cement
Time, the influence difficulty of construction of core pile forming technology are larger, and construction quality and duration are not easy to guarantee.
The relatively flourishing coastal region in east China of economy in China, widely distributed moisture content is high, compressibility is big, permeability
Difference, intensity is low, mud of high sensitivity and Muddy Bottoms bury, and mixing pile pile strength size and play degree by soil property,
The influence of the factors such as underground water is very big, especially encounters muck soil, peat soil etc., construction quality is difficult to control；Precast concrete
Core stake needs to be aligned before sinking to stirring pile center, in the actual construction process, it is difficult to ensure that core stake stake position is absolute placed in the middle, and
It is easily glanced off during sinking to, is finally difficult to reach the desired effect of composite pile；The stake of injection core, not only needs in soil cement
Biggish energy is consumed, and it is also larger to surrounding environment influence to vibrate itself, simultaneously because vibration-extrusion acts on, in stake week
The excess pore water pressure generated in soil is also not easy to dissipate.
Summary of the invention
In view of the above-mentioned problems, the present invention proposes a kind of new type cement soil composite pile, including main pile body, stake core, sandstone pad
