Description
Technical field
The utility model relates to building field, particularly relates to a kind of triaxial cement mixing pile pile-forming equipment.
Background technology
Triaxial cement mixing pile is, by three axes agitating pile machine, cement paste is injected the soil body, and by machine, cement paste and soil shear failure is even, after grout cures, and a just formation cylindric induration in soil layer.Cement mixing method reinforces the bearing capacity that can improve foundation soil, increases the passive earth pressure of the soil body inside enclosure wall, reduces the compressive strain of the soil body and the horizontal movement of enclosure wall, increases the stability of resistance to chloride ion and excavation slope bottom foundation ditch.
Another important function of three axes agitating pile is used as foundation pit waterproof curtain, especially in urban architecture compact district, for pit earthwork excavation is convenient, need to carry out drainage precipitation to the soil body inside foundation ditch, differential settlement is produced for preventing buildings around foundation pit, pipeline etc., need at foundation pit enclosure structure arranged outside one water-stop curtain, to cut off the hydraulic connection inside and outside foundation ditch.
Cement grout is pumped in drilling rod, sprays in the soil body with less pressure by cement grout, by stirring vane by cement grout and soil body uniform stirring.
There is following problem in current conventional drill rod structure:
(1) work efficiency is not high, and triaxial cement mixing pile pile relies on drilling rod power to creep into completely, and pile-forming speed is slower;
(2) displacement soil is more, the displacement of current triaxial cement mixing pile soil amount be about pile body long-pending 30%;
(3) due to after slurries flow out from drilling rod, slurry pressure is very little, and grout mixing is little, stirring vane be difficult to by itself and soil shear failure all with, pile quality does not ensure, after pit earthwork excavation, often can cause leakage accident.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of triaxial cement mixing pile pile-forming equipment, can solve triaxial cement mixing pile work efficiency not high, and displacement soil is more, the shortcoming that special formation pile quality is poor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of triaxial cement mixing pile pile-forming equipment, comprise three drilling rods, a drill bit is provided with separately in the bottom of every root drilling rod, some helical blades are evenly provided with from top to bottom outside the shaft of every root drilling rod, an inlet channel is offered in the inside of intermediate drill, described inlet channel comprises a valve, described valve is arranged at corresponding drill tip, a feed pathway is offered respectively in the inside of both sides drilling rod, in described feed pathway, a feed tube is set respectively, described feed pathway comprises nozzle A, described nozzle A is arranged at corresponding drill tip, described feed tube comprises nozzle B, described nozzle B is arranged at corresponding drill tip, the position of described nozzle B is lower than the position of described nozzle A.
Preferably, described feed tube adopts sebific duct, and the caliber of described sebific duct is less than feed pathway, and feed pathway is used for external water under high pressure, gas or high water-cement ratio cement paste, and sebific duct is used for external water under high pressure mud.
Preferably, described drill bit is connected with adopting pin between drilling rod, is convenient to disassembled for transport.
The beneficial effects of the utility model are: the utility model offers passage and sebific duct in drilling rod inside, and water under high pressure mud is sprayed in drill bit, can the broken drill bit position soil body, and make soil structures loose, drill bit creeps into easier; Water under high pressure (high pressure gas or high water-cement ratio cement paste) sprays by nozzle, the soil body around broken agitation pile, make surrounding soil loosely organized, the cement-soil fluid stirred can flow rapidly in the hole of surrounding soil structure, reduces the displacement soil of three axes agitating pile; Water under high pressure (high pressure gas and water under high pressure mud) impacts surrounding soil, and cause soil structures to loosen, grout mixing expands, and under the dynamic action of drill bit, cement grout and soil body uniform stirring, pile quality is reliable, and stagnant water effect is good.
