The construction technology of the whole envelope structure has the advantages of being friendly to the environment, high in effect, low in cost, free of slurry pollution, small in soil-squeezing and effect on the environment and the like.
Description
Technical field
The present invention relates to a kind of continuous multi-shaft cement mixing wall and insert the space enclosing structure that combines of reinforcing cage castinplace pile (abbreviation guncreting pile) and construction method thereof with after long auger guncreting, be mainly used in civilian and industrial infrastructure construction build in bracing of foundation pit sealing and braced cuts.
Background technology
The concrete filling pile construction method of current routine has the castinplace pile etc. of the castinplace pile of dry operation pore-forming, the castinplace pile of mud off pore-forming, the castinplace pile of casing pipe hole forming and explosive expansion pore-forming
The construction process of bored concrete pile flow process of dry operation pore-forming: sediment → hole quality at the bottom of land clearing → surveying setting-out fixed pile → pile-forming machine perching → boring extracting soil pore-forming → cleaning hole is inspected for acceptance → install reinforcing cage → pouring hole inner concrete.
The castinplace pile of mud off pore-forming utilizes mud off, during boring by circulating mud by the native slag tap under bit cutting outer and pore-forming, then install reinforcing cage, underwater concreting and pile.
Casing pipe hole forming castinplace pile utilizes impact pile driving method or vibrosinking, and by with valve type pile shoe or sink in soil with the steel sleeve of precast concrete shoe, then limit is pulled out cover tube edge concrete perfusion and formed.If when being furnished with reinforcing bar, then before fluid concrete, first hang cage of reinforcement.Utilize hammer piling equipment immersed tube, tube drawing, be called hammer hidden pipe caisson pile; Utilize the vibration sinking tube of vibrator, tube drawing, be called vibrator pipe sinking cast-in-place pile.
Conventional construction process of bored concrete pile is all first put reinforcing cage usually, then concreting.There is waste concrete, environment pollution, shortcoming that cost is higher in current Concrete Grouting Pale, construction period aspect is also to be improved simultaneously, construction machinery intelligence degree is not high, is many times reinforcedly all experience according to field personnel and determines, and well can not carry out monitoring management.
Summary of the invention
Agitation pile involved in the present invention is novel five (six) axle Soil-cement Walls (hereinafter referred to as FCW engineering method), this engineering method uses novel intellectuality five (six) axle ram machine construction, once at most can pile five (six) root, without displacement soil, to some extent solve the deficiency of above-mentioned several agitation pile technique, have efficient, without the feature of displacement, intelligent, environmental protection.
The present invention is achieved through the following technical solutions:
The space enclosing structure that a kind of five (six) axle agitation piles combine with reinforcing cage castinplace pile slotting after long auger guncreting, five (six) described axle agitation piles adopt ground, cities five axle Soil-cement Wall construction technologies (hereinafter referred to as FCW engineering method); Castinplace pile inserts reinforcing cage castinplace pile after adopting long auger guncreting.
The construction method of described one five (six) axle Soil-cement Wall, its construction method comprises the following steps:
(1) setting-out, open channels, device is in place, and five (six) axle cement-soil mixing pile devices are moved to position to be onstructed;
(2) start backstage cement paste stirring system, then cement paste is delivered to slurry storage bucket;
(3) open integrated computer, allow computer control the data pre-set: every meter of decrease speed, every meter of whitewashing amount, stake end design elevation, total whitewashing amount and total mixing time;
(4) head that turns on the power drives Multifunctional drill, while stirring water-spray type slurry, rotates forward absolute altitude at the bottom of sinking whitewashing 70% to design wall.
(5) stir again in absolute altitude 0.5 ~ 1 meter of interval at the bottom of wall.
(6) brill is carried on reversion whitewashing limit, limit, and reversion whitewashing 30% to wall top mark is high;
(7) get final product pile one on the other, form gravity dam as required;
(8) one groups of constructions terminate, and move to second group and continue construction.
Insert reinforcing cage castinplace pile after described long auger guncreting, its construction method comprises the following steps:
(1) smooth location, the setting-out of stake position;
(2) Installation and Debugging rig, lays steel pile casting (as needs);
(3) debug concrete pump, pump line is installed;
(4) driller insertion;
(5) boring to projected depth stops creeping into;
(6) limit infusion Superfluid state concrete limit promotes drilling rod;
(7) propose drilling rod, remove drilling tool;
(8) reinforcing cage, vibrating hammer is lifted by crane;
(9) the lower slotting reinforcing cage of Vibration on Start-up hammer is to design elevation;
(10) Stake head handling;
(11) one groups of constructions terminate, and move to second group and continue construction.
Five (six) described axle agitation piles and the combining form of castinplace pile can be the form be arranged side by side or the form that both are connected in snap-in manner, also can be the forms that castinplace pile is embedded between many row's agitation piles.
The invention has the advantages that:
1, castinplace pile of the present invention bores under adopting auger stem and carries soil, and promote auger stem and pour into Superfluid state concrete by the hollow part of drilling rod simultaneously, more traditional construction technology, shortens the engineering time, and efficiency of construction is higher;
2, traditional handicraft whitewashing amount and drilling down and up, does not install flow instrument and depth sensing instrument, and construction is complete by rule of thumb.Existing equipment has installed corresponding computer sensing instrument, reaches requirement that is directly perceived, effective, automation, ensure that quality.
3, the present invention can one-step pore-creating, not only ensure that construction quality but also shorten the construction period;
4, in stake, arrangement of reinforcement adopts high tensile reinforcement, and horizontal direction anti-bending strength is also better, gives full play to high tensile reinforcement tension, both concrete anti-compressions advantage, more economical in cost.
5, agitation pile adopts novel five axle construction technology constructions, and increase than traditional handicraft pile quantity, efficiency of construction is significantly improved, and without displacement soil, pollution-free generation.
6, agitation pile adopts novel five axle construction technology constructions, and the cost of engineering water-stop curtain aspect can save about 20%.
7, agitation pile adopts novel five axle construction technologies constructions, and the plant equipment of employing contains Intellectualized monitoring equipment, and workmanship is guaranteed, and solving that cement in mixing pile construction technique uses cannot the shortcoming of accurate-metering.
