Abstract
The invention relates to a method for forming variable-diameter cement-soil stirring piles. By utilizing a dynamic system, a drill tower and a traction system of a common uniaxial or biaxial cement-soil stirrer in the prior art, changing a power-speed control system and the structure of a stirring-shaft blade and utilizing the changes of the rotation direction of a stirring shaft, the length of the stirring-shaft blade is increased and decreased according to engineering demand so as to achieve the aim of forming different-diameter cement-soil stirring pile bodies in different positions. The specific content of the method comprises that: 1, a structure form of a telescopic stirring blade of the variable-diameter cement-soil stirring piles; 2, the manufacture of the telescopic stirring bladeof the variable-diameter cement-soil stirring piles, wherein the telescopic stirring blade of the variable-diameter cement-soil stirring piles is cast in high-grade hard alloy steel, and the drillingof holes and the processing of hinge pins and positioning pins are performed according to designed dimensional requirements; and the size of each part of the variable-diameter telescopic stirring blade; and 3, a method for lengthening and contracting the telescopic stirring blade.
Description
One, technical field:
The present invention relates in the geotechnical engineering soft soil is reinforced and a kind of reducing agitation pile of supporting, especially when reinforcing different soil, require the different-diameter cement mixing method body of formation, so that effectively improve the strength and stiffness of ground.
Two, background technology:
When soft layer being reinforced with supporting, usually adopt cement paste and soil body stirring method, form the cement mixing method body, thereby the intensity of soft foundation is greatly improved.Stirring facility commonly used at present, formed cement mixing method body is isodiametric cylinder.Because foundation soil body is layered distribution, strength and stiffness between each layer soil all have certain difference, that have even difference is very big, therefore, require when ground is carried out consolidation process, should be at different soil layers, form the cement mixing method body of different-diameter, thereby make whole Measures for Making Ground and Foundation, can reach higher strength and stiffness requirement, can reduce construction cost again and improve work efficiency.We can say that can conveniently form the facility that become the diameter cement mixing method is a kind of new demands in foundation treatment technology field.
Three, summary of the invention:
Utilize the single shaft commonly used at present or dynamical system, boring tower and the trailer system of dual spindle soil-cement stirring, by changing the blade construction of its dynamic Control and speed control system, shaft, press ground and handle needs, utilize the variation of the direction of rotation of shaft, the length of blade of elongation and shortening shaft is implemented in the purpose that diverse location is made different-diameter cement mixing method body.
The particular content of patent of the present invention is as follows:
1, the form of structure of variable-diameter cement-soil stirring piles retractable blades
The form of structure of variable-diameter cement-soil stirring piles retractable blades as shown in Figure 1, this blade is made up of fixed blade, flexible blade, rotating pin and alignment pin.When shaft turned clockwise, retractable blades was folded state, and the diameter of stirring vane diminishes; When shaft is rotated counterclockwise; Retractable blades is launched, and it is big that the diameter of stirring vane becomes.
In work progress, stirring vane has crept into and has been reinforced in the soil layer, is all wrapped up by the soil body and cement grout all around, and this retractable blades structure must stuck, native stone intrusion not occur and block the flexible phenomenon of blade under this environment.We are through test and engineering practice in different soil, and the phenomenon of not getting up can not appear not opening, receiving in this blade construction form of our design.
2, the processing of variable-diameter cement-soil stirring piles retractable blades and manufacturing
The variable-diameter cement-soil stirring piles shaping blade adopts senior hard alloy steel casting to form, and carries out jewel hole and processing bearing pin and alignment pin by the dimensional requirement of design.
The each several part size of reducing stirring vane as shown in Figure 2.
3, the flexible method of control stirring vane,
Utilize the power supply phase place of unit head to change, change the direction of rotation of the shaft of cement-soil mixing pile machine, being stirred the soil body changes to the resistance that stirring vane produces, utilize this to stir soil body drag effect, just telescopic stirring vane is opened or folded up, thereby changed the length of stirring vane, variation has just taken place in the native earth stirring pile body diameter that forms by this method, thereby can be implemented in the purpose that diverse location forms different-diameter cement mixing method body.
As shown in Figure 1, when shaft is rotated counterclockwise, scalable stirring vane is opened under soil body drag effect automatically.Otherwise, when shaft turns clockwise, scalable stirring vane just under the soil body drag effect auto-folder get up, thereby realize changing automatically stirring vane length, form the effect of different-diameter agitation pile.
Four, description of drawings
The form of structure of the scalable stirring-head of Fig. 1 variable-diameter cement-soil stirring piles
1---shaft, blade, 3--alignment pin, 4--rotating pin, 5-that 2--is fixing are in folding position, the telescopic stirring vane of 6-, the shaft direction of rotation when 7-is in extended position, 8-leaf folding.
Fig. 2 reducing stirs the each several part size of retractable blades
The stirring vane length that L0-is fixing; The telescopic stirring vane length of L1-is determined by designing requirement; L2-reducing length; The L3-shaft is apart from the central axis of rotating pin; The distance of the telescopic stirring vane one end distance rotating pin of L4-.The 1-shaft.
Five, the specific embodiment
(1) measurement and positioning;
(2) mixing pile machine and reducing is installed is stirred retractable blades, corresponding dynamic Control and stir the direction of rotation controller is installed on shaft;
(3) by the stake footpath of design, control corresponding direction of rotation, with the broken soft soil of rotary cutting mode;
(4) go into cement paste by auger spindle hollow tube pressure injection;
(5) while stirring spray;
(6) when needing the position of reducing, change the spinning solution of shaft, just make the retractable blades of mixing pile machine pack up or open;
(7) by new agitation pile diameter, the flow and the pressure of control cement paste inject cement paste while stir.
Claims (1)
- Utilize the single shaft commonly used at present or dynamical system, boring tower and the trailer system of dual spindle soil-cement stirring, by changing the blade construction of its dynamic Control and speed control system, shaft, by requirement of engineering, utilize the variation of the direction of rotation of shaft, the length of blade of elongation and shortening shaft is implemented in the purpose that diverse location is made different-diameter cement mixing method body.The claim of patent of the present invention:1, the form of structure of variable-diameter cement-soil stirring piles retractable blades2, the manufacture method of variable-diameter cement-soil stirring piles retractable blades3, realize the elongation of scalable stirring vane and the method for contraction, that is: by changing the direction of rotation of shaft, utilize soil body resistance to promote the elongation and the contraction of retractable blades.
