Description

Pile reinforcement structure {REINFORCEMENT STRUCTURE FOR PILE}

The present invention relates to the field of civil engineering, and in particular, to the structure of the pile.

The construction method of piles to form the foundation of the structure on the ground can be largely divided into the method of entering the factory manufacturing pile by driving, and the method of installing the reinforcement in the drilling hole and placing the concrete in the field.

The former anti-punching method uses a hollow tube structure or a PHC pile formed with upper and lower trims as piles. When the piles are driven, the soil is introduced through the lower trims and at some point consolidation is applied to the lower ground. As no more inflow of soil occurs (expressing 'floor clogging' in the field), a stable foundation can be formed.

This anti-taking method has the advantage of excellent construction convenience and stability of the structure, but has the disadvantage that a large noise generated by the driving during construction.

The latter, on-site casting method has the opposite advantages and disadvantages.

On the other hand, in the anti-puncture method has been developed to install a shoe (tip expansion shoe) having a larger diameter than the diameter of the pile at the bottom of the pile, which is because the area of the shoe (tip) of the pile is widened Accordingly, since it is possible to secure a greater tip support capacity, it is possible to increase the stability of the foundation structure, thereby reducing the number of piles, there is an advantage that can reduce the construction cost.

However, in such a conventional method, studies on the structure of attaching the tip extension shoe to the lower end of the pile have been insufficient, and the following problems have been pointed out.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the reinforcement structure (A) of the pile according to the present invention is basically, a protruding coupling member 100 protruding upward to fit the lower trimming portion of the tubular pile body (10). ; It is configured to include; expansion shoe forming member 200 coupled to the lower portion of the protruding coupling member 100 to form an expansion shoe having an outer diameter larger than the outer diameter of the pile.

That is, instead of taking the method of joining the expansion shoe to the lower end of the pile by welding or the like, the protruding coupling member 100 formed in the reinforcing structure is inserted into the lower trimming portion of the pile main body 10 and is merely fitted to the fitting. It is to take the manner of mounting.

Accordingly, the construction of the pile and the reinforcing structure (A) is completed by placing the reinforcing structure (A) near the perforation hole in the field, carrying the pile (10) by the equipment, and simply laying it on the reinforcing structure (A). It can be done (Fig. 1).

Therefore, it is possible to reduce the effort and time required for the installation of the tip expansion shoe as in the prior art, and by expanding the construction work by lifting the pile combined with the reinforcing structure (A) by the above equipment and inserting it into the drilling hole. It is effective that there is no fear of damage to the shoe.

Protruding coupling member 100 is coupled by friction with the inner wall of the lower end of the pile body 10, so the lower end of the pile only to maintain the coupling until the bottom of the hole, it is not necessary to achieve a very strong coupling.

This is because the pile body 10 and the reinforcing structure A are forced in the direction in which the pile body 10 and the reinforcing structure A are coupled to each other by hitting the bottom of the punched hole.

Such friction coupling is made relatively firm, and in order to easily perform the coupling operation (work to lift the pile by the equipment to lower the predetermined position) of the protruding coupling member 100 and the pile body 10. , It is preferable to take the structure formed so that the width of the portion to be bonded to the lower inner wall of the pile main body 10 becomes narrower (inclined) toward the upper side and the inner side (FIGS. 1 to 4).

Hereinafter, embodiments of the structure of the protruding coupling member 100 will be described.

When the portion of the protruding coupling member 100 coupled to the lower inner wall of the pile body 10 is formed to be curved, the above effects can be obtained even more (FIGS. 3 and 4).

When the protrusion coupling member 100 has a plate-like structure installed in the lateral direction, it is possible to obtain an efficient structure that achieves a firm coupling while reducing the material.

If the protruding coupling member 100 takes a semi-circular cross-sectional structure, even when the lower end of the pile does not initially reach the correct position during the coupling operation of the pile, it will be easier to find the coupling position by sliding, making the coupling operation easier. The advantage is that it can be done easily (Fig. 4).

Protruding coupling member 100 is installed so that the pair is orthogonal to each other, it is more preferable in terms of structural stability and ease of operation to take a planar "+" shaped structure.

Hereinafter, embodiments of the structure of the extension shoe forming member 200 will be described.

Basically, the expansion shoe forming member 200 has a configuration including a sealing member 200a having a plate-like structure having an outer diameter larger than the outer diameter of the pile, thereby obtaining a structure of a general tip expansion shoe (FIGS. 1 to 4). .

In addition, the expansion shoe forming member 200 may have an openable structure as shown in FIG.

That is, the expansion shoe forming member 200 is coupled to the bottom outer end of the protruding coupling member 100, the support member 210 is formed with a recess in the core; An opening and closing plate 220 installed to open and close the lower trimmed portion of the support member 210; A central support member hinge portion 211 formed at the front end of the bottom of the support member 210; A central connection member 231 having one end connected to the central support member hinge portion 211; A central opening and closing plate hinge portion 221 formed at the core of the opening and closing plate 220 while the other end of the central connecting member 231 is connected; A pair of both supporting member hinge parts 212 formed at both ends of the bottom of the supporting member 210; A pair of both side connecting members 232, one end of which is connected to a pair of both side support member hinges 212, respectively; And a pair of both opening and closing plate hinge parts 222 formed at a rear side of the opening and closing plate hinge part 221 of the opening and closing plate 220 and connected to the other ends of the pair of both connecting members 232. By the hinge driving of the central connecting member 231 and the pair of both connecting members 232, the opening and closing driving of the opening and closing plate 220 may be performed.

Due to the hinge structure as described above, the opening and closing driving of the opening and closing plate 220 is performed by the hinge driving of the central connecting member 231 and the pair of both connecting members 232.

That is, the opening and closing plate 220 in the opening state of the pile body 10 to the drilled hole to take the open state (Fig. 8), the opening and closing plate 220 to reach the bottom of the drilled hole to take the closed state (FIGS. 9 and 10).

This has the following effects.

First, since the opening and closing plate 220 is opened during the insertion of the pile body 10, the pile is suspended by buoyancy of the grout or other fluid present in the drilling hole, so that the pile is not disturbed by the rooting operation and the bottom of the drilling hole. Since the opening and closing plate 220 is in a closed state, it is possible to secure the tip support force by only a few strokes by forcibly blocking the floor.

Therefore, the pile according to the present invention, even when applied to the construction method of the partial piercing method of the boring to ensure sufficient support capacity (to ensure the floor is blocked) to achieve a stable foundation structure, and to reduce the construction cost It works.

Secondly, since the opening and closing plate 220 opens and closes the lower pile trim in a state in which the opening and closing plate 220 maintains a circular shape, there is little concern about a problem caused by deformation of the opening and closing plate 220 structure.

Third, since the opening and closing drive structure by four hinges is taken from the side, free deformation is possible, and there is little risk of damage when lifting from a storage place or laying down near a drill hole.

The support member 210 constituting the extension shoe forming member 200 is coupled to the bottom outer end of the protruding coupling member 100, and takes a configuration in which a slit is formed in the core, which is implemented by a ring structure. It is preferable in terms of structural stability with respect to the structure described below.

The opening and closing plate 220 is inserted into the drilling hole in the state hanged downward by its own weight, in order to allow the up and down driving (closed driving) to occur smoothly as the lower end of the opening and closing plate 220 is in contact with the bottom of the drilling hole. It is necessary to allow the front end of the opening and closing plate 220 to be inserted into the punched hole in a state inclined toward the front (Figs. 8 and 9).

To this end, the central opening and closing plate hinge portion 221 and a pair of both sides of the opening and closing plate hinge portion 222, the opening and closing plate 220 in the state that the front end of the opening and closing plate 220 toward the bottom by opening the opening and closing plate 220, Preferably, the front end of the 220 is formed at a position to tilt forward (Figs. 5 and 6).

The central opening and closing plate hinge portion 221 is formed in the core portion of the opening and closing plate 220, the opening and closing plate 220 is formed so as to be located inside the trimmed portion of the support member 210 to avoid the hindrance of the structure. More preferred (Figs. 5, 6).

The central support member hinge portion 211 may take a configuration protruding downward from the pile body 10, in which case, in order to avoid contact between the central support member hinge portion 211 and the opening and closing plate 220, the opening and closing plate ( In a state in which 220 is closed, it is preferable to take a configuration in which the central hinge member insertion hole 223 is formed in the opening and closing plate 220 so that the central support member hinge portion 211 is inserted (FIGS. 5 to 7).

In addition, when the present invention is applied to the above-described concrete pile, there is a fear that contact between the concrete pile body 10 and the central connection member 231 occurs in the state in which the opening and closing plate 220 is closed.

In order to prevent this, the central connection member 231 has a head portion 2311 whose one end is connected to the central support member hinge portion 211; An inclined portion 2312 having one end connected to the other end of the head 2311 and formed to be inclined upward; It is preferable that one end is connected to the other end of the inclined portion 2312, and the tail portion 2313 is formed to be inclined downward and the other end is connected to the central opening and closing plate hinge portion 221; 7).

In this case, a part of the head portion 2311 and the inclined portion 2312 is inserted into the central hinge insertion hole 223 while the opening and closing plate 220 is closed, thereby avoiding contact with the concrete pile body 10. Can be.

The pair of both supporting member hinge parts 212 may be mounted on the outer side of the supporting member 210 to avoid contact with other members. In order to completely prevent possible contact, the opening and closing plate may be In a state in which the 220 is closed, it is preferable to take a configuration in which a pair of both hinge portion insertion holes 224 are formed in the opening and closing plate 220 so that the pair of both support member hinge portions 212 are inserted ( 5,6).

The central connection member 231 and the pair of both side connection members 232 are coupled to the above-described hinges to play the opening and closing drive of the opening and closing plate 220, so that such driving can be performed smoothly. When the rear end of the opening and closing plate 220 is driven upward by the opening of the opening and closing plate 220, the rear end of the opening and closing plate 220 and the lower end of the main body 10 are formed to have a length such that they do not come into contact with each other. It is preferable (FIGS. 5 and 6).

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
