The apparatus of the utility model is composed of a drill bit, a motor, a control platform, a drill frame, a drill rod, a transmitting chain, a slurry-feeding pipe, a pressurizing pump and a model box. The utility model realizes the functions of ration design of control transformation and control bearing capacity of a composite foundation and transfer of soils between piles through pile soil stress ratio adjustments.
Description
Technical field
The utility model relates to a kind of control modulus stake pile-forming equipment, belongs to geotechnical engineering composite foundation bearer properties field tests.
Background technology
Composite foundation is present most popular a kind of soft-soil foundation treatment method in the current geotechnical engineering field, because the complexity of foundation soil condition, at present the bearer properties mechanism research of composite foundation is difficult to satisfy the requirement of actual engineering, it can only be the quantification that semiempirical half is simplified, because pile and testing equipment can not satisfy the needs of research, have seriously restricted the deep development of theory of composite foundation.Laboratory test often adopts the Model Pile of organic material to carry out, and result of the test and actual monitoring result come in and go out bigger.Just because of Model Pile and relevant device exist very big inadaptability, relevant research and design can only be in by virtue of experience or the state of existing engineering priori.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of control modulus stake pile-forming equipment at the defective that prior art exists.
The utility model control modulus stake pile-forming equipment, by drill bit, motor, controlling platform, drilling cramp, drilling rod, driving-chain, feed pipe for mortar, force (forcing) pump, model casing is formed, wherein drill bit and drilling rod all are provided with longitudinal hole, the delivery outlet of force (forcing) pump is communicated with the top through hole of drilling rod by feed pipe for mortar, the bottom of drilling rod and the top of controlling platform are oppositely arranged, the bottom of controlling platform and the top of drilling cramp are fixed, the top of driving-chain is oppositely arranged with the cross bar on drilling cramp top respectively, the bottom of driving-chain is oppositely arranged with the two ends, the left and right sides of controlling platform respectively, motor is fixed on the power transmission shaft of the top of drilling cramp and motor and driving-chain and controlling platform and is oppositely arranged, the bottom of drill bit and controlling platform is oppositely arranged, the bottom of drilling cramp is provided with model casing, and model casing is positioned at the below of drill bit.
Drill bit 1 adopts full augers to guarantee that the boring behind the pore-forming can not cause the phenomenons such as hole, distortion of collapsing because of the lateral pressure of soil, guarantee pore-forming the quality outside diameter be 5cm, the aperture of drill bit internal (is the mud jacking hole, being communicated with feed pipe for mortar) aperture is 1.0～1.5cm, so that cement mortar can be pressed into bored pile.
The output pressure of cement mortar is kept in the control of cement mortar delivery pump, and cement mortar is injected in the boring incessantly.
The utility model design is carried out pile by adjusting different cement paste proportionings, it is consistent with the material of actual engineering piles to make into pile material, and can quantitatively control the modulus of Model Pile, realize the design of controlled deformation, realize the controlled deformation of composite foundation and the quantitative design of control bearing capacity, give full play to the effect of inter-pile soil by the stress ratio of adjusting stake soil.

The specific embodiment
As shown in Figure 1.A kind of control modulus stake pile-forming equipment, by drill bit 1, motor 2, controlling platform 3, drilling cramp 4, drilling rod 5, driving-chain 6, feed pipe for mortar 7, force (forcing) pump 8, model casing 10 is formed, wherein drill bit 1 and drilling rod 5 all are provided with longitudinal hole, the delivery outlet of force (forcing) pump 8 is communicated with the top through hole of drilling rod 5 by feed pipe for mortar 7, the top of the bottom of drilling rod 5 and controlling platform 3 is oppositely arranged, the top of the bottom of controlling platform 3 and drilling cramp 4 is fixed, the top of driving-chain 6 is oppositely arranged with the cross bar on drilling cramp 4 tops respectively, the bottom of driving-chain 6 is oppositely arranged with the two ends, the left and right sides of controlling platform 3 respectively, motor 2 is fixed on the power transmission shaft of the top of drilling cramp 4 and motor 2 and driving-chain 6 and controlling platform 3 and is oppositely arranged, drill bit 1 is oppositely arranged with the bottom of controlling platform 3, the bottom of drilling cramp 4 is provided with model casing 10, and model casing 10 is positioned at the below of drill bit 1.
Full augers guarantees that the boring behind the pore-forming can not cause the phenomenons such as hole, distortion of collapsing because of the lateral pressure of soil, outside diameter is 5cm, cement mortar is pressed into pile in the boring by the intercommunicating pore of drill bit internal, the pressure of mud jacking is controlled at about 15.0-20.0kPa, can not be too fast in the process of pile for avoiding occurring speed that broken pile requires to promote drill bit, laboratory test was controlled at about 1.5-2.0cm/ minute, or rose by the anti-drill bit that pushes away of mud jacking.Weak soil stops up the cement mortar leadout hole of drill bit bottom when preventing to hole, and need keep an equilibrium pressure in the defeated slurry passage of drill bit internal during boring, and equilibrium pressure is generally 5.0-10.0kPa.d.) load plate test, control modulus stake and deformation design
Maintenance is 28 days behind the pile, and the former humidity that maintenance is banketed between curing time prevents water evaporates.The load plate test that control modulus stake maintenance can be correlated with after 28 days, as bearing capacity, side friction, stress ratio etc., bearing capacity with the checking composite foundation, adjust of the influence of the stiffness measuring different-stiffness pressing plate of pressing plate, can control the design and the composite foundation Deformation Control Design of modulus stake like this according to the theory of composite foundation to stress ratio.
