Abstract
The utility model discloses the compacted bearing disk pile that a kind of Near Ground place expands section, is a kind of basis of electric power facility.Comprise on circumference the pile body with branch, at pile body upper end, underground, be provided with and expand section post, the diameter that expands section post is 1.5～2.5 times of pile body normal section diameter, and the scope that expands section post is 1～5 meter of below ground.Expand between section post and pile body normal section and be set to pyramid type changeover portion.In pile body, be provided with the elongated reinforcing bar of perforation, expand elongated being provided with in section post and block reinforcing bar, at the lower end and the elongated steel bar welding that block reinforcing bar, be connected to horizontal dowel.The compacted bearing disk pile of this Near Ground place enlarging section has overcome the shortcomings such as in conventional art, structure stress is inhomogeneous, material can not make full use of, and has improved horizontal bearing capacity, and has reduced arrangement of reinforcement consumption, has accelerated construction speed in the time of cost-saving.
Description
Technical field
The utility model relates to the basis of electric power facility, refers in particular to a kind of compacted bearing disk pile with expanding section post.
Background technology
In power construction process, whether the basis of electric power facility (as steel tower) can firm buried National People's Congress ground be very important.Basis is generally cast in basic hole and is formed by steel concrete.Compacted bearing disk pile is on former common filling pile (equal diameter stake) basis, to increase the basis that force bearing disk or branch form is set, and pile body (basis) is comprised of king pile, several disk or several branches that are arranged on king pile circumference.Compacted bearing disk pile has obviously improved resistance to compression, the anti-pulling capacity of pile foundation, but because branch setting position is darker, its Its ultimate bearing capacity can not improve.Exist many irrational places, such as: while 1) only having branch buried depth larger, compare with equal diameter stake, the resistance to compression of compacted bearing disk pile, resistance to plucking supporting capacity just can increase substantially, and Its ultimate bearing capacity can not improve; 2) the king pile stake footpath that can only add in the long scope of timber pile meets the restriction that horizontal movement is located on design ground, must increase concrete amount and amount of reinforcement like this; 3) due to the increase of the workloads such as borehole, filling concrete, reinforcing cage establishment, certainly will extend construction period.
Utility model content
The utility model technical issues that need to address are to provide a kind of stock utilization, cost-saving compacted bearing disk pile of improving, its can improve the standard ability of carrying.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of Near Ground place expands the compacted bearing disk pile of section, comprise on circumference the pile body with branch, at pile body upper end, underground, be provided with and expand section post, the diameter that expands section post is 1.5～2.5 times of pile body normal section diameter, and the scope that expands section post is 1～5 meter of below ground.
Further improvement of the utility model is: between described expansion section post and pile body normal section, be set to pyramid type changeover portion.
Further improvement of the utility model is: in described pile body, be provided with and connect the elongated reinforcing bar at the upper and lower two ends of pile body and be arranged on the reinforcing bar that blocks expanding in section post, block the elongated vertical direction that expands section post that is arranged on of reinforcing bar, at the lower end and the elongated steel bar welding that block reinforcing bar, be connected to horizontal dowel.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows:
The utility model adopts and at pile body, near vicinity, ground (referring to below ground), produces the scheme that expands section post, expand section post and adopt changeover portion to be connected with compacted bearing disk pile normal section, the reinforcing bar that blocks that expands section post welds mutually by dowel and elongated reinforcing bar.Thereby overcome the shortcomings such as the compacted bearing disk pile Its ultimate bearing capacity in conventional art is not enough, material can not make full use of, improved stock utilization.When electric power facility meets larger lateral force, basis of the present utility model can provide larger horizontal resist forces, causes pile foundation and not run-off the straight of electric power facility.
Expansion section post described in the utility model, scope is for pushing up to below ground more than 1 meter from stake, in 5 meters, it is the best that expansion section post is imbedded underground 3～5 meters, so both controlled the place's horizontal movement of design ground, strengthened the Its ultimate bearing capacity of compacted bearing disk pile, reduce again steel concrete and amount of reinforcement, thereby saved cost, accelerated construction speed.
Elongated reinforcing bar of the present utility model, block the setting of reinforcing bar and dowel, increased the intensity of pile foundation, pyramid type changeover portion can reduce the stress concentration phenomenon of pile body.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
Wherein: 1, expand section post, 2, changeover portion, 3, pile body, 4, branch, 5, block reinforcing bar, 6, dowel, 7, elongated reinforcing bar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Near Ground place expands a compacted bearing disk pile for section, comprises pile body 3, and pile body 3 main bodys are isometrical cylinders, cylindrical pile body 3 on circumference, be also provided with branch 4, branch 4 is that formed by integrally casting forms with pile body.In pile body 3 upper ends, be provided with and expand section post 1, expand section post 1 and have at least a part to imbed underground, expanding section post 1 buried height is 1～5 meter, preferably 3～5 meters of below grounds; The diameter that expands section post 1 is 1.5～2.5 times of pile body 3 normal section diameters, generally can be arranged to 2 times.At expansion section post 1, be provided with pyramid type changeover portion 2 with the transition position that is connected between pile body 3 normal sections.In pile body 3, be provided with elongated reinforcing bar 7, elongated reinforcing bar 7 connects pile body, and Shang Xia 3 two ends, and elongated reinforcing bar 7 can be reinforcing cage.In expanding section post 1, be provided with and block reinforcing bar 5.Block reinforcing bar 5 and be arranged on the vertical direction that expands section post 1, block reinforcing bar 5 length can with expand the equal in length of section post 1, block elongated being arranged on of reinforcing bar 5 and expand in section post 1, at the lower end and the elongated reinforcing bar 7 that block reinforcing bar 5, be welded with horizontal dowel 6.
During construction, first according to the intended diameter pore-forming at pile body normal section place; It is squeezed that next utilizes extruding-spreading device to carry out at set branch position by order from bottom to top, and expanding section post is to adopt continuous squeezed mode to form equal diameter to expand section post; By the boring of blocking reinforcing cage that reinforcing bar 5, dowel 6 and elongated reinforcing bar 7 be welded into and putting into mud off; The concrete being stirred is poured in boring from bottom to top, form branch 4, normal section 3, changeover portion 2 and expand section post 1.
