Description
Technical field
The invention belongs to building lots and foundation construction technical field, are concretely related to a kind of compound tubular pole of soil cement and apply
Work engineering method.
Background technique
The compound tubular pole of soil cement: by what the compound construction of soil cement and prestressed concrete pipe pile was formed there is complementary enhancing to make
Pile body.Inner core is prestressed concrete pipe pile；Outer core is cement earth pile.
Currently, in the compound tube pile construction of soil cement there are two types of the formation of cement earth pile: first is that realized with Pressure Revolving Blast-Grout,
Its principle is the height from the nozzle of slip casting tube edge after prefabricated slurries make liquid stream obtain huge energy by high pressure emitter
Speed ejects, and forms the liquid stream of one energy height concentration, directly the destruction soil body, and in course of injection, drilling rod is mentioned in rotation
It rises, is thoroughly mixed slurries with the soil body, form the column induration of certain diameter in soil.Its disadvantage: 1, cement slurry wave
Take seriously, because cement slurry is injected always, finally has a large amount of cement slurries and overflow ground, therefore cost greatly improves.2, due to ground
The a large amount of mud in face, cause ground largely to pollute.Second is that Soil-cement piling method forms cement earth pile, principle is to utilize cement
As curing agent, by special Mixing Machine, in ground depths by weak soil and curing agent action of forced stirring, curing agent and soft is utilized
Generated a series of physical chemical reaction between soil makes the hard solution of weak soil at globality, water stability and some strength it is excellent
Matter soil cement.Its disadvantage such as pile quality lacks monitoring device, and stifled soil pile breaking phenomenon need to be monitored manually, the skill of operator
Art is horizontal and operation is half-hearted, therefore soil cement uniform quality cannot be completely secured.
Summary of the invention
It is an object of the invention to provide a kind of short construction period, without waste, without construction site pollution soil cement it is compound
Tube pile construction engineering method.
To achieve the above object, technical solution provided by the invention are as follows:
A kind of compound tube pile construction engineering method of soil cement, step include:
Concrete stake pore-forming: it completes to take soil at stake position using drilling machine, realizes concrete stake pore-forming；
Soil-cement: described that soil is taken to form soil cement slurry with cement mixing while completing the concrete stake pore-forming；
Cement earth pile casting: the soil cement slurry is perfused into the cement stake holes, forms cement earth pile；
Compound tubular pole is formed: in the tubular pole indentation cement earth pile, will form that inner core is tubular pole, outer core is answering for cement earth pile
Close tubular pole.
In above-mentioned construction,
--- the tubular pole for constituting the inner core is steel tubular pole or prestressed concrete pipe pile.
The present invention compared with prior art, i.e., is poured by pre- stirring concrete earth in institute using long-spiral drilling machine construction method
In the stake holes of formation, the formation of cement earth pile is realized, then replant into tubular pole, i.e. the completion compound tubular pole of soil cement；The soil cement
Compound tube pile construction engineering method has the following characteristics that first, have the characteristics that short construction period, saves more than half compared with bored concrete pile
Duration saves a quarter duration compared with composite foundation；Second, stirring because of soil cement and being perfused by long spire in advance, therefore do not deposit
In any waste of cement and composite soil；Third, that is, drilling cements out since there is no the races of cement slurry to emit for construction ground
Native most undergrounds that poured into the form of soil cement again form cement earth pile, therefore construction ground is neatly clean.
Detailed description of the invention
Fig. 1 is the compound tube pile construction engineering method flow diagram of soil cement provided by the invention.
Specific embodiment
The compound tube pile construction engineering method process principle of soil cement provided by the invention is done further in detail with reference to the accompanying drawing
Explanation.
As shown in Figure 1, the compound tube pile construction engineering method flow diagram of soil cement provided by the invention.That is soil cement multiple tube
The construction of tubular pole are as follows: complete that soil is taken to realize concrete stake pore-forming 2 at stake position 1 first with long-spiral drilling machine；In completion
While stating cement stake holes pore-forming, the soil taken is delivered to mixing plant and cement mixing forms soil cement slurry 3；By above-mentioned cement
Soil paste pumps the top for being delivered to long-spiral drilling machine by pumping mechanism 4, by hollow auger stem by lower and upper perfusion to institute
It states in concrete stake pore-forming 5 and forms cement earth pile；Before being formed by cement earth pile solidification, tubular pole is pressed by static pressure mechanism 6
Wherein, the compound tubular pole 7 that inner core is tubular pole, outer core is cement earth pile is formed.Wherein the tubular pole of above-mentioned inner core be steel tubular pole or
Prestressed concrete pipe pile.
Due in above-mentioned construction, by the soil in the cement stake holes taken out, almost or greatly portion is used for and cement mixing
Form the soil cement slurry of pumping, compared with the existing technology in Soil-cement piling method form cement earth pile, can be according to requiring
It realizes that cement mixes in proportion with native, the dirt ratio for being formed by cement earth pile, the matter of effective monitoring pile can be controlled
Amount；Mesohigh rotary spraying grouting method forms cement earth pile compared with the existing technology, not only can effectively avoid mud and overflows and causes to waste,
And have technique relatively easy and can equally control the uniformity of cement content, be conducive to the control of pile quality.
