Abstract

The utility model provides a pile follower for burying preformed piles, which comprises a pile body and a base connected at the lower part of the pile body, wherein the base is provided with a plurality of preformed holes; the section of the pile body of the pike follower takes the shape of a hollow square or round; and the pile body of the pile follower is filled with concrete. The pile follower has the effects of overcoming the method of conventional pile preforming without adopting the pile follower that when in manufacture, a protecting pile head exceeding the anchorage length is additionally manufactured on the basis of designing the pile length, and when the foundation pit is excavated to a designed elevation, the needless concrete is removed, the steel bar is cleaned out, and the foundation concrete is anchored. By adopting the pile follower for burying the preformed piles, the anchored steel bar is arranged higher than the concrete, and the protecting pile head does not need to be lengthened when in manufacture of the preformed piles, thus reducing the break-down quantity of concrete of the protecting pile head by more than 85 percent, further being capable of avoiding waste and improving the efficacy.

Description

Bury the Pile feeder of preformed pile down

Technical field

The utility model relates to the instrument of doing the basis in the civil works, particularly a kind of Pile feeder that buries preformed pile down.

Background technology

Preformed pile is a kind of stake type commonly used, mainly is used as resistance to compression, resistance to plucking or the horizontal force resistant of building or structure.Because of technology or function needs, the stake top of most stakes is the below ground of place elevation when construction all, some project has basement because of building, stake top buried depth surpasses 10 meters sometimes, and because of the structure requirement, the stressed main reinforcement in the preformed pile needs with superstructure certain anchorage length is arranged, general requirements is 35d, d is the diameter of stressed main reinforcement, and stressed main reinforcement does not allow the welding of same level face, so there is following defective in existing preformed pile:

The way of conventional preformed pile is to increase on the basis at designing pile length to make the protection pile crown that surpasses anchorage length when making; when treating excavation of foundation pit to design altitude; clean out reinforcing bar after more unnecessary concrete being rejected and anchor into base concrete; when engineering quantity is big; make pile crown and cause significant wastage, abolishing and clear pile crown is that lost labor's machinery expense delays the duration again.

So, be necessary to improve from the structure of Pile feeder and the job practices aspect of preformed pile, to overcome above-mentioned defective at as above problem.

Summary of the invention

For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of Pile feeder that buries preformed pile down, is beneficial to reach the purpose that improves effect, improves the quality, avoids waste.

For achieving the above object, the technical solution adopted in the utility model provides a kind of Pile feeder that buries preformed pile down, wherein: described Pile feeder includes pile body and is connected the base of pile body bottom, is provided with a plurality of preformed holes on described base, gets rid of passing of muscle with what make things convenient for preformed pile.

The cross section of described Pile feeder pile body is the square or circular of hollow.

Be filled with concrete in the described Pile feeder pile body.

Effect of the present utility model is the deficiency that has overcome conventional way; way as the conventional preformed pile of Pile feeder as described in not adopting is to increase on the basis at designing pile length to make the protection pile crown that surpasses anchorage length when making; when treating excavation of foundation pit, clean out reinforcing bar after more unnecessary concrete being rejected and anchor into base concrete to design altitude.Adopt described Pile feeder, when preformed pile is made, anchor bar is exceeded concrete, do not need lengthening to make the protection pile crown, reduce more than 85% of the protection pile crown concrete amount of abolishing, can avoid waste, improve effect.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings is illustrated Pile feeder structure of burying preformed pile down of the present utility model.

Pile feeder structure of burying preformed pile down of the present utility model is that described Pile feeder includes pile body and the base 2 that is connected pile body 1 bottom, is provided with a plurality of reinforced holes 3 on described base 2.

The cross section of described Pile feeder pile body 1 is the square or circular of hollow, is filled with concrete 4 in the pile body 1 of described Pile feeder.

Pile feeder structure function of burying preformed pile down of the present utility model is achieved in that

As shown in Figure 1, 2, described Pile feeder includes pile body 1 and is connected the base 2 of pile body bottom, and a plurality of preformed holes 3 of reserving on the base 2 of the pile body 1 of Pile feeder pass conveniently to get rid of muscle 7.

As shown in Figure 3, be the circular hollow section of the pile body 1 of Pile feeder, for strengthening pile body rigidity at circular cavity fill concrete.

As shown in Figure 4, be the square hollow section of the pile body 1 of Pile feeder, for strengthening pile body rigidity at square cavity fill concrete.

As shown in Figure 5, be conventional Pile feeder, the same cross section of total length, bottom are tack.

As shown in Figure 6, conventional preformed pile need extend when making and make prefabricated pile crown 8, and the prefabricated pile crown of lengthening making contains and gets rid of muscle 7;

Shown in Fig. 5,6, general preformed pile Pile feeder 5 commonly used, no matter the side's of being stake or circle stake, its preformed pile 6 needs to reserve 500～800mm and gets rid of muscle 7 and prefabricated pile crown 8, this part be not counted in the stake of effective precast square pile or circle stake long in, need reject prefabricated pile crown 8 when to be slotted, anchor bar be exposed be used for connecting the basis.The following Pile feeder that buries preformed pile that the utility model provides can be delivered to design altitude with getting rid of the preformed pile that muscle 7 exceeds stake top.As shown in Figure 7, reserve the schematic diagram that gets rid of muscle, adopt this method when preformed pile is made, will get rid of muscle and exceed concrete for adopting Pile feeder construction of the present utility model; do not need lengthening to make the protection pile crown; reduce more than 85% of the protection pile crown concrete amount of abolishing, can avoid waste, improve effect.
