Abstract
The utility model relates to a bottle gourd pile which is in a column shape and is formed into integration in the mode of concrete pouring. The pile body is made into a bottle gourd series shape, the inner part is provided with a cylindrical reinforcing cage, and the bottle gourds are arranged on positions of a pile hole bearing stratum with intervals. Each bottle gourd has big bottom part and small upper part and is in a garlic shape. The maximum radius of the bottle gourd pile is enlarged 200 mm to 600 mm than the radius of the cylindrical pile body. Because the bearing capacity of the bottle gourd pile acts on one side wall of the pile hole and a plurality of bearing stratums which are arranged at the lower part of the pile hole and has certain thickness, one root of pile is equivalent to the action of a plurality of roots of common concrete filling piles. The ultimate bearing capacity can be improved a plurality of times, and the expense of pile producing is reduced more than 1 time. So the bottle gourd pile is suitable for areas with various qualities of soil and areas which are unsuitable for providing a long pile.
Description
The utility model belongs to a kind of concrete spouting pile element in underground making.
Available coagulation soil castinplace pile is cylindrical, the expanded bore pile that also has the stake bottom to enlarge.Along with increasing gradually of middle-high building, require the supporting capacity of building constantly to increase, cause quantity, stake footpath and the stake appearance of cast-in-place concrete pile to increase.Building pile foundation cost, pile workload, duration, engineering cost are all obviously improved.Suddenly treat a kind of improved stake type.
The purpose of this utility model provides a kind of Bottle gourd pile, increases the supporting capacity of single pile foundation, to reduce piling quantity, reduces the pile foundation cost, the reduction of erection time, saves engineering cost.
The technical solution of the utility model is:
Bottle gourd pile is the cylindricality that concrete and reinforcing bar are built one, it is characterized in that: pile body is a cucurbit string shape, and inside is provided with cylindrical reinforcing bar cage, and cucurbit is located on the position of bearing stratum with interval, big at the bottom of each cucurbit, go up little, be head of garlic shape.
The cucurbit maximum radius of Bottle gourd pile enlarges 200～600 millimeters than cylindrical pile body radius.
The interval of each cucurbit is 2 meters at least.
Have certain thickness cobble, sandstone etc. to hold on the power stratum because the bearing capacity of Bottle gourd pile acts at the bottom of the sidewall in a hole and the hole and the cucurbit bottom is several, therefore, a pile just is equivalent to the effect of several ordinary concrete castinplace piles.Its ultimate bearing capacity can improve several times, reduces the pile expense more than 1 times.
The utility model with Bottle gourd pile drill bit drilling and forming hole, adopts the premium mud guard aperture earlier when making, be drilled into bearing stratum and carry out reaming; Continue after the reaming to creep into, be drilled into bearing stratum reaming again, reaming finishes and creeps into, to enlarged opening on pile bottom, becomes the Bottle gourd pile hole; Clear then hole is to conforming with " technical code for building pile foundation " requirement; Reinforcing bar cage hoisting is in place; Concrete perfusion; Pile.
The utility model should be determined to design the layout of Bottle gourd pile by " technical code for building pile foundation " requirement when design according to the function of use of building structure, load character, stake.Distance between each cucurbit is decided on the diameter of bearing stratum position, interval and cucurbit.Little when the bearing stratum supporting capacity, when the cucurbit diameter is big, should strengthen the design pitch of cucurbit, prevent from the bearing stratum at cucurbit place is crushed; Otherwise its spacing can dwindle.The conventional design value of cucurbit spacing is 3～4 meters.The cucurbit number of Bottle gourd pile is 2～5, is 3～4 generally speaking.Can be according to the decision of bearing capacity of single pile size.
The utility model has the advantages that: under the situation identical with cylindrical stake pile body diameter, its ultimate bearing capacity can improve several times; Under the identical situation of total load, adopt Bottle gourd pile can reduce building piling quantity, reduce the concrete spouting amount, it is long to shorten stake; Thereby can improve programming, and the reduction of erection time, reduce the pile workload, save engineering cost more than one times; Compare with bottom-enlarging filling pile with cylindrical castinplace pile, the Bottle gourd pile more reasonable stress, stability is better; Be applicable to various soil properties area and long special area should not be set.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a planform schematic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
As shown in the figure, Bottle gourd pile is the cylindricality of concrete and reinforcing bar cast one, and pile body is a cucurbit string shape, and inside is provided with cylindrical reinforcing bar cage 1, and cucurbit 2 is located on the position of bearing stratum with interval, big at the bottom of each cucurbit, go up little, be head of garlic shape.The cucurbit maximum radius of Bottle gourd pile enlarges 200～600mm than cylindrical pile body 3 radiuses.The interval of each cucurbit is 2 meters at least, and the most frequently used is 3～4 meters.The cucurbit number is 2～5, and accepted value is 3～4.
Embodiment: pile body diameter * cucurbit tripe diameter can have following size (mm):
600×1000；600×1200；800×1400；800×1600；
800×1800；1000×1800；1000×2000；1200×2200；
1400×2400；1600×2600；1800×2800；2000×3000。
Above size also can design as requested.
