Abstract
The invention provides a deep mixing pile-micro pre-stressed steel pipe concrete pile-vertical anchor rod composite foundation pit support method. The method comprises the following steps: (1) constructing the deep mixing pile; (2) grouting at an anchoring end; and (3) forming the micro pre-stressed steel pipe concrete pile. The method has the advantages that as the deep mixing pile is equipped with the micro pre-stressed steel pipe pile and an anchor rod or an anchor rope, the bending and shearing bearing capacity thereof is improved; the antidumping and anti-slip capability of the wall body of the mixing pile is improved under the condition of not exceeding a land red line; and meanwhile the combined support method has the advantages of short construction period, low noise, no pollution and no soil squeezing and is very beneficial to environmental protection during the construction process, thus being a novel combined support member and a method which are worth to be popularized and applied.
Description
Technical field
The present invention relates to technical field of buildings, a kind of specifically deep-mixed pile+micro pre-stressed steel pipe concrete stake+vertical anchor rod composite foundation pit support method.
Background technology
The safety of foundation ditch is directly connected to the safety of life and property, how to guarantee the safety of foundation ditch under the condition of economical rationality, and crucial problem depends on the reliability of support system.And the conventional deep-mixed pile gravity barricade that uses, it is all relatively poor that its bending resistance, shearing resistance, overturning or slip resistance analysis and antiskid move ability, is easy to produce under the soil pressure effect destroy, and influences the safety of foundation ditch and surrounding building, therefore, is necessary prior art is improved.
Summary of the invention
The objective of the invention is to develop and a kind ofly can effectively improve the bending resistance of deep-mixed pile gravity barricade, shearing resistance, overturning or slip resistance analysis and antiskid and move ability, and easy construction, deep-mixed pile+micro pre-stressed steel pipe concrete stake+vertical anchor rod composite foundation pit support method that cost is low.
Deep-mixed pile of the present invention+micro pre-stressed steel pipe concrete stake+vertical anchor rod composite foundation pit support method, its step is as follows:
1, construction deep-mixed pile;
2, Deep Mixing Piles Construction was finished in 12 hours, with engineering driller pore-forming in agitation pile, anchor pole or anchor cable was inserted the anchored end soil layer, carried out anchored end slip casting;
3, treat slurries solidify after with steel pipe socket at the bottom of passing the agitation pile endoporus on anchor pole or the anchor cable and inserting deep-mixed pile, build the concrete cover plate and solidify the post tensioning anchor pole or anchor cable applies prestressing force and locks with ground tackle, cement injection or pea gravel concreten in steel pipe form the micro pre-stressed steel pipe concrete stake again.
Described anchored end external diameter, outer diameter of steel pipes are identical with agitation pile endoporus external diameter.
Steel pipe can be round steel pipe or square steel pipe in the described deep-mixed pile.
Described anchor pole is a Ribbed Bar, and described anchor cable is a steel hinge line.
The advantage of deep-mixed pile of the present invention+micro pre-stressed steel pipe concrete stake+vertical anchor rod composite foundation pit support method is: because micro pre-stressed steel pipe stake and anchor pole or anchor cable are set in deep-mixed pile, improved its bending resistance, shear-carrying capacity, the overturning or slip resistance analysis and the antiskid that improve the agitation pile body of wall simultaneously under the situation that does not exceed the land used red line move ability.This combination supporting worker method duration in work progress is short, noise is little, pollution-free, soil compaction not, and is very favourable to environmental protection, is a kind of novel combination supporting member and method that is worthy of promotion and application therefore.

3, treat slurries solidify after with round steel pipe be enclosed within pass the agitation pile endoporus on the Ribbed Bar and insert deep-mixed pile at the bottom of, build the concrete cover plate and solidify the post tensioning Ribbed Bar and apply prestressing force and lock with ground tackle, cement injection in round steel pipe forms the micro pre-stressed steel pipe concrete stake again.
Described anchored end external diameter, outer diameter of steel pipes are identical with agitation pile endoporus external diameter.
Embodiment two
According to Fig. 1, shown in Figure 2, a kind of deep-mixed pile+micro pre-stressed steel pipe concrete stake+vertical anchor rod composite foundation pit support method, its step is as follows:
1, construction deep-mixed pile;
2, Deep Mixing Piles Construction was finished in 12 hours, with engineering driller pore-forming in agitation pile, steel hinge line was inserted the anchored end soil layer, carried out anchored end slip casting;
3, treat slurries solidify after with square steel pipe be enclosed within pass the agitation pile endoporus on the steel hinge line and insert deep-mixed pile at the bottom of, build the concrete cover plate and solidify the post tensioning steel hinge line and apply prestressing force and lock with ground tackle, in square steel pipe, annotate pea gravel concreten again, form the micro pre-stressed steel pipe concrete stake.
Described anchored end external diameter, outer diameter of steel pipes are identical with agitation pile endoporus external diameter.
The invention is not restricted to above embodiment, can realize a plurality of different embodiment as required.
