Description

Construction file {PILE FOR USING CONSTRUCTION}

The present invention relates to a pile for construction, and more particularly, it is used in a device in which pile drilling and pile driving are performed at the same time, so that the construction can improve the closeness and verticality when continuously installed in the ground. It's about public files.

In general, when constructing reinforced concrete structures or other buildings, foundation works are constructed by embedding PHC and steel pipe piles or H-beams in the ground to strengthen the foundation of the ground. Construction of piles is very important in constructing structures and buildings.

As a method for constructing piles in foundation works, pour construction methods and excavation construction methods are used.The pour construction method uses a lifting rope installed on the upper part of a reader installed vertically in a crane to raise and drop the hammer of a heavy body. This is a method of placing piles and inserting them into the ground while raising or lowering the hammer using compressed air of the compressor, and the excavation method is to excavate the ground by rotating the screw rod mounted on the auger machine. After the ball is formed, the screw rod is rotated in reverse to remove it from the excavated pile ball, and then the pile is inserted into the pile ball.

In addition, there is a CIP (Cast In Concrete Pile) method for forming a reinforced concrete pile in the hollow pile inserted after the hollow pile is inserted into the ground by the pile construction method.

Referring to the conventional CIP method with reference to the accompanying drawings as follows. 1 is a view for explaining a conventional CIP method. As shown, using the auger machine to jump through the hollow pile 1, 2, 3 one by one in order to insert and then reinforce the reinforcing bars or reinforcing bars in the hollow pile (1, 2, 3), and cast concrete When the curing is completed, the space between the hollow piles 1, 2, and 3 is drilled with an auger machine, and then the piles 4, 5, and 6 are sequentially inserted, and then the reinforced concrete is formed in the hollow piles 4, 5 and 6.

The reason for inserting the hollow piles (1,2,3,4,5,6) into the gaps in the conventional CIP method is to rotate when the hollow piles (1,2,3,4,5,6) are inserted. When installing the piles in a line adjacent to the hollow file installed first, when the hollow file is installed in a row because the clamping part of the file inserted later cannot be inserted deep so as not to interfere with the hollow file installed first. As shown in FIG. 2, the length exposed to the ground becomes long as it progresses. Therefore, in the CIP method, the hollow piles 1, 2, 3, 4, 5, and 6 are inserted into the gaps.

Therefore, the conventional CIP method is adversely affected by disturbing the surrounding ground due to the rotation of the hollow piles (1, 2, 3, 4, 5, 6), and the construction of the pile by drilling and pile driving proceed separately The time required, of course, had the problem of increasing costs.

In addition, as shown in Figure 1 by the construction by the hole, when the anti-taking verticality and soil quality is poor, the gap (d) occurs between the hollow pile (3, 5), resulting in poor construction, which is the reason after this CIP construction Due to the clearance (d) had to be carried out a separate order construction had a problem that wastes time and money.

Therefore, when placing the upper end of the pile as a hammer, the impact sound and vibration are largely generated, and when the screw rod of the auger machine is removed from the excavated pile hole, the soil around the pile hole collapses to fill the pile hole. However, in order to solve the shortcomings of the excavation method having the problem of increasing the air by drilling the pile hole and the piling operation of the pile separately and the CIP construction method having the above problems, the drilling and pile driving of the pile are simultaneously performed. As a result, a pile construction device has been developed that reduces the time required for construction of the pile and minimizes the disturbance of disturbances and noise by inserting the pile into the perforated pile without rotating the pile. It is used in the equipment and inserted into the ground continuously, not in a perforated manner. In addition, it is necessary to develop a pile file that can increase the degree of closeness so that the verticality is excellent and mutual play does not occur.

The present invention is to solve the above-mentioned problems, the object of the present invention is to be used in the device that is carried out at the same time the drilling of the pile hole and the pile driving operation of the pile, the degree of adhesion through the sliding coupling between each other when continuously installed in the ground And to provide a construction construction pile to improve the verticality.

The present invention for realizing the above object, in the pile installed in the pile hole drilled in the ground by the drilling rod, the body is formed in a hollow so that the drilling rod is inserted to drill the path to be inserted, and the outside of the body First and second guide coupling portions are formed on both sides of the side along the longitudinal direction, respectively, the first guide coupling portion is inserted into the ground and slidingly coupled with the second guide coupling portion of the other pile type at the neighboring point, the other pile It is characterized in that the guide to be in close contact with each other.
