Description
Technical field
The utility model relates to a kind of construction equipment of concrete pedestal pile.
Background technology
In the foundation construction of building, usually adopt cast-in-place concrete pile, a kind of form of construction work of this stake is to adopt casing and post hammer to construct, it such as notification number disclosed mode in the utility model patent manual of CN1093582C, promptly ram casing or ram that the soil body makes casing sink to desired depth in the casing by post hammer, thereby form the stake hole, and then form tamper diffusion head at the stake end by post hammer, and perfusion pile concrete when promoting casing, thus whole cast-in-place concrete pile formed.When stake footpath during big or foundation soil harder (as hard plastic clay or completely decomposed basement rock), the suffered sidewall friction power of casing is bigger, thereby is difficult to casing be sunk to desired depth or propose from assigned position, and construction quality and work efficiency are affected.In addition, this method often causes adjacent pile body come-up or pile defects such as broken pile, necking down owing to soil compaction effect when the sinking casing.
The utility model content
The purpose of this utility model is: a kind of concrete pedestal pile construction equipment that borrow equipment can effectively overcome the frictional resistance of casing and soil layer that has is provided, this equipment is suitable for the pile foundation construction that the stake footpath is big, pile body is long especially, and is also very suitable to harder soil layer.
The technical solution of the utility model is: a kind of construction equipment of concrete pedestal pile, comprise that the bottom has the chassis ridgepole of supporting leg and walking mechanism, the chassis ridgepole front end is fixed with the body frame that has upright guide rail, body frame passes through the hound support and connection on chassis ridgepole, body frame is provided with assembly pulley, be fixed with main winch and secondary hoist engine on the chassis ridgepole, the steel cable that stretches out from secondary hoist engine is connected with casing after walking around the auxiliary pulley of assembly pulley, the steel cable that stretches out from main winch is connected with the post hammer after walking around the head pulley of assembly pulley, the post hammer is positioned at casing and can moves up and down along casing, the lower end of described casing is equipped with soil sampler, described casing top is fixed with vibratory impulse hammer one, and the steel cable that is connected with casing connects vibratory impulse hammer one.The vibratory impulse hammer one that casing top connects, fast, successfully immersed tube is to desired depth can to make casing.
Body frame described in the utility model adopts single or many root architectures; Be connected with two hounds on the described body frame, the other end of hound is connected to the diverse location on the chassis ridgepole, and two hounds and body frame form three-point support structure jointly with the junction of chassis ridgepole.Owing to adopt said structure, strengthened the rigidity of pile frame widely, strengthened stabilization of equipment performance.
Described post peen end is fixed with the vibratory impulse hammer, and the steel cable that is connected with the post hammer connects the vibratory impulse hammer.Owing to adopt said structure, more help promoting the post hammer to move up and down in casing inside, it is close to be implemented in shaking of a bottom, hole fast, and this structure especially is suitable for the site construction that water level is higher, soil layer is harder.
Described soil sampler adopts by the seamless pipe weldering of two joint different-diameters make the reducing type soil sampler that forms at least, and the caliber of this reducing type soil sampler diminishes from top to bottom step by step.Owing to adopt said structure, significantly reduce the soil and the contact friction of soil sampler inwall that enter soil sampler, spoir easily, thereby raising work efficiency.For the fine and close soil layer of moulding firmly, should use the reducing type soil sampler.
Described soil sampler adopts side direction through-hole type soil sampler, and this soil sampler is the tubular structure that tube wall is provided with the soil digging hole.For more open soil layer, should use side direction through-hole type soil sampler.
The supporting leg of described chassis ridgepole has four, all adopts the hydraulic leg of being convenient to stretch.In utilizing the work progress of this construction equipment, the chassis on the pile frame is supported on the ground by 4 hydraulic legs. and when mobile construction equipment, 4 hydraulic legs shrink, and the walking mechanism of bottom, chassis contacts with ground, can realize the displacement of equipment easily and turn to.
In the utility model, because sinking, casing provides power by the hammer of the vibratory impulse on the casing one, particularly the non-soil compaction method of soil taking hole forming has been adopted in the stake hole, greatly reduce casing and the frictional force of soil and the soil compaction effect of stake, casing is sunk to desired depth or propose than being easier to from assigned position, work efficiency is improved, and also can avoid causing adjacent pile body come-up or pile defects such as broken pile, necking down owing to soil compaction effect when the sinking casing, and construction quality is guaranteed.This worker's method is particularly suitable in stake footpath big or adopts during foundation soil fine and close hard (as hard plastic clay or completely decomposed basement rock).This worker's method cast-in-place concrete pile of both can having constructed, the plain concrete pile body in the composite foundation of also can constructing.
(band soil sampler or not with soil sampler) provides power by the vibratory impulse hammer one of casing upper end because casing sinks, and sinks to having higher work efficiency than the hammering casing.
Owing to adopt construction equipment of the present utility model to form the non-soil compaction method that soil taking hole forming has been adopted in the stake hole, greatly reduce the frictional force of casing and soil, casing is sunk to desired depth or propose than being easier to from assigned position, work efficiency is improved.Such as in fine and close hard plastic clay ground, adopting non-soil extracting process every day can pile 6, adopt soil extracting process construction every day can pile more than 12, work efficiency can double.What is more important adopts the construction technology of soil taking hole forming, and the soil compaction effect of stake significantly reduces, and can avoid when the sinking casing because soil compaction effect causes adjacent pile body come-up or pile defects such as broken pile, necking down.Such as in fine and close hard plastic clay ground, adopting non-soil extracting process, general adjacent pile body come-up or the pile defects such as broken pile, necking down of just can causing, the engineering that has exists the pile foundation of defective to reach more than 90%, after adopting the soil extracting process construction, can avoid substantially because the pile defect that soil compaction effect causes.
Because the vibratory impulse hammer that the compacting of filler can be adopted the hammering compacting of post hammer or be arranged at post peen end carries out the vibratory impulse compacting, the construction of a stake end enlarged footing has stronger specific aim and better practicability.
The beneficial effects of the utility model are: adopted casing to be provided with the soil sampler structure, help preventing the damage of casing, prolonged the application life of casing, and soil sampler is changed conveniently, different geological conditionss can be chosen the soil sampler of different structure, and adaptability for working condition is strong; The vibratory impulse on casing top hammer one can make casing fast, successfully immersed tube has improved operating efficiency greatly to desired depth.During the situation of especially big or foundation soil harder (as hard plastic clay or completely decomposed basement rock) for stake footpath, be easier to casing be sunk to desired depth or propose from assigned position, work efficiency is improved, also can avoid may causing adjacent pile body come-up or pile defects such as broken pile, necking down owing to soil compaction effect when the sinking casing, construction quality is guaranteed.
