Description

Basic rebar insertion device

1 is a longitudinal cross-sectional view of a casing that is made of rebar.

2 is an X-ray cross-sectional view of FIG.

3 is a state diagram excavated by the injection water.

4 is a state diagram at the time of hardening material injection.

5 is a state diagram at the time of rebar insertion.

6 is a state diagram in which branches are drawn out.

The present invention relates to a basic reinforcing bar insertion device, and more specifically, to insert a corrugated body having an umbrella-shaped branch in the grouted uncured soil together with the casing, and then press down the bone to a predetermined position from the hole drilled in the casing. It relates to an insertion apparatus as a basic reinforcing bar to take the end of the branch of the corrugated body out of the casing and to fully inject a hardener into the casing so that the inside and the outside of the casing are integrated by the hardener so that the ground has a stable strength.

Conventional foundation grounds are often formed by simply placing concrete piles in the ground, but in many cases, due to the shape of the piles, the stability is not good and is easily shaken out. In addition, in the case of concrete piles, vibration noise at the time of pouring becomes unbearable pollution, and the stability was worsened when buried using a method other than the placing method.

The present invention is to insert the casing into the ground and then to extend the basin to the body stored in the inside to draw the casing in the four directions in the surrounding ground of the casing to stabilize the casing to be able to easily insert the casing to avoid pollution It is the insertion device of the basic rebar.

That is, an object of the present invention is to provide a device capable of forming a solid ground by inserting reinforcing bars to a predetermined position by reducing resistance in the uncured hardened material and then spreading the branches in the uncured hardened material.

Hereinafter, an embodiment of the basic rebar insertion device according to the present invention will be described in detail with reference to the accompanying drawings.

The casing 1 is divided into a plurality, molded and combined, and then connected and fixed by a connecting piece 2, and one end of an umbrella-shaped branch 4 is connected to the corrugated body 3 of a rod-like shape at intervals. (1) vertically through the guide plate (5) made in the inside and the tip of the branch is inserted into the guide hole (6) drilled in the casing (1) to be drawn out to the outside of the casing (1) along the guide hole (6) 3) the upper part of the casing (1) to protrude from the upper end of the casing (1) when it is pushed down to be almost coplanar with the upper end of the casing (1), the upper end of the casing (1) through the connector (7) The cap 8 is detachably formed and is formed in the shape of an awl at the bottom, and the grout penetration hole 9 is drilled at the end.

Reference numeral 10 denotes a double injection pipe, 11 and 12 are injection holes, 13 are swivels, 14 and 15 are hoses, and 16 are driving devices.

The present invention having the structure as described above, the injection pipe 10 supported by the drive device 16 is first installed on the ground surface of the foundation ground, while rotating and driven by the drive of the drive device 16 in the usual way, and lowered The water is pumped from the water tank into the injection pipe 10 through the high pressure pump and the hose 14 and sprayed from the injection hole 11 at the end, excavated by the injection water, and the mud is discharged by the air lift action. After the excavation is completed, the excavation is prevented from the water tank to connect with the hardening material tank and connected to the hardening material tank to pressurize the hardening material in the injection pipe 10 by the high pressure pump and the hose 15, and the hardened material is injected by the injection hole 12 at the end. After the injection, while the injection pipe 10 is rotated up to finish the injection of the curing material, the injection pipe 10 is pulled out. After the injection of the conventional hardening material is completed, the casing 1 containing the corrugated body 3 and the branch 4 is inserted in the grout state in which the hardening material is not cured, and inserted into the predetermined position and the bone body stored in the casing 1 ( 3) Pressing down, the branch 4 cracked from the bone body 3 is guided along the guide hole of the casing 1, protruding into the uncured grout, and the branch 4 and the bone body 3 steel the casing 1 As the rebar is in close contact with the strong ground is effective.

In the casing 1, when the casing 1 is inserted, the hardener penetrates from the hole 9 in the front part, or the induction hole 6 and the front part of the casing 1 which are fed from the upper part and the hardener is supplied from the upper part. Sometimes it flows out from the hole (9).

Claims (1)

The casing 1 is divided into a plurality, molded and combined, and then connected and fixed by a connecting piece 2, and one end of an umbrella-shaped branch 4 is connected to the corrugated body 3 of a rod-like shape at intervals. (1) vertically through the guide plate (5) made in (1) and the tip of the branch is inserted into the guide hole (6) drilled in the casing (1) is drawn out to the outside of the casing (1) along the guide hole (6), The upper part of the casing (1) is projected more than the upper end of the casing (1) so that when the branch (4) is unfolded and pressed down, it is almost flush with the upper part of the casing (1), and the connector (7) is attached to the upper part of the casing (1). Base reinforcing bar insertion device formed through the cap (8) to be detachable, and the awl-shaped at the bottom and the grout penetration hole (9) at the end.
