Description
Technical field
The present invention relates to a kind of lattice combined steel plate pile cement-soil composite pile and construction method thereof, belong to Geotechnical Engineering base
Support technology field, hole.Be applicable to cutting depth, level of ground water buries shallow base pit engineering building enclosure, especially high in water content
Weak clay, more aobvious advantage under the geological conditions such as silt.
Background technology
Tradition SMW engineering method stake is in the application of foundation pit supporting construction, and its lateral rigidity is mainly undertaken by the section bar inserted, and
Cement mixing method is contributed as flexible pile or Half rigid pile its lateral rigidity of the illegallest consideration, therefore tradition SMW engineering method stake
Practical application in horizontal distortion relatively big, this is also this engineering method bottleneck of popularization and application in complicated base pit engineering.
In foundation pit supporting construction, support pile is to control horizontal distortion, so just improving the core of support pile service behaviour
It is intended to improve the lateral rigidity of pile body on the premise of certain economy with construction convenience.For SMW engineering method stake, if only
The rigidity relying on raising section bar improves the lateral rigidity of whole compound pile body, then will sharply increase with steel cost, pile body section
Also will be enlarged by, this certainly will make its economy reduce and difficulty of construction increase.So, in sum, the work of SMW engineering method stake to be improved
Make performance core mainly to improve from taking effective way or play the lateral rigidity of cement mixing method.
Summary of the invention
Technical problem: it is an object of the invention to provide a kind of lattice combined steel plate pile cement-soil composite pile and construction party thereof
Method, on the basis of the thinking of tradition SMW engineering method stake, changes original general section bar inserted, change into by linear type steel sheet pile and
The square lattice of narrow wing I steel composite is as the reinforcing body of Rigid cable, before the hardening agent hardening of cement system
Inserting, after pile, the follow-up practice of base pit engineering is all consistent with other supporting pile-type base pit engineering with working procedure.This by cement
Soil is placed in inside the square lattice of combined steel plate pile so that the soil cement in lattice combined steel plate pile cement-soil composite pile is by passing
System engineering method in be placed in outside shaped steel unidirectional stretch bending stress become three dimension stress state, this given full play to soil cement resist
Compressive Strength is much larger than tension, the characteristic of shearing strength, and this will be greatly improved the lateral rigidity of cement mixing pile.
Technical scheme: the present invention is structural shape and the construction party thereof of a kind of lattice combined steel plate pile cement-soil composite pile
Method, this composite pile includes linear type steel sheet pile, narrow wing I-steel, cement-soil mixing pile, stake apical cap beam and internal support of foundation pit;
Wherein, linear type steel sheet pile lays respectively at outside two edges of a wing of narrow wing I-steel, and both is positioned in cement-soil mixing pile;
The arrangement mode of cement-soil mixing pile is: be provided with linear type steel sheet pile and narrow wing work in first cement-soil mixing pile
Word steel, is provided only with linear type steel sheet pile in second cement-soil mixing pile, is provided with in the 3rd cement-soil mixing pile
Linear type steel sheet pile and narrow wing I-steel, be provided only with linear type steel sheet pile, the most successively in the 4th cement-soil mixing pile
Arrangement is gone down;Be positioned at the linear type steel sheet pile two ends of even number root cement-soil mixing pile respectively be positioned at odd number root soil cement
Linear type steel sheet pile in deep-mixed pile connects, above-mentioned component couple together and constitute lattice combined steel plate pile soil cement
Composite pile.
The construction method of the lattice combined steel plate pile cement-soil composite pile of the present invention comprises the following steps:
The first step: construction cement-soil mixing pile;
Second step: outside narrow wing I-steel two edge of a wing and linear type steel sheet pile smears interleaving agent;
3rd step: guide frame and suspension beam that combined steel plate pile inserts are set;
4th step: control the most vertical in cement mixing method inserting through the correction of theodolite deviational survey before soil cement is unhardened
Enter narrow wing I-steel, outside upper lower flange, then insert linear type steel sheet pile, complete a combination lattice;
5th step: having continued another adjacent combination lattice, the fore shaft of adjacent straight line style steel sheet pile is connected with fore shaft
Together, thus formed one combination lattice unit;
6th step: construct at the underground wall body top of lattice combined steel plate pile cement-soil composite pile composition and pour stake top
Guan Liang, the closing envelope inner excavation inner support at underground wall body arranges construction groove, and inner support of constructing, in finally applying
Support and weld with the connector of described lattice;
7th step: soil excavation in foundation ditch, completes building underground structure main body construction;
8th step: remove inner support and stake apical cap beam;
9th step: smear interleaving agent inside and outside thermoplastic combination lattice, arranges guide frame and suspension beam that lattice is extracted,
Extract the combination lattice in cement mixing pile;
Tenth step: Foundation Pit Construction is complete.
Beneficial effect: the present invention uses above technical scheme, possesses following advantage: compared with prior art by by water
Earth is enclosed in inside lattice the stress changing soil cement, its overall lateral rigidity is greatly improved, takes into account simultaneously
Tradition SMW engineering method stake stagnant water effect is good, construction method quick, without Site Welding, practicality cheap, capable of circulation, have concurrently
Gear soil and water stopping function, solve the problem that in the practical application of tradition SMW engineering method stake, horizontal distortion is bigger.
