본고안은 건물등을 신축하기 위한 기초공사를 할때 스크류 오거(Screw auger) 장치의 오거봉을 지반에 박은 상태에서 곧바로 콘크리트액을 타설할수 있도록 하므로서 기초공사를 보다 견고하면서도 신속 용이하게 행할수 있도록 한 고안에 관한 것이다.In this paper, when the foundation construction for building construction, etc. is carried out, the concrete auger rod of the screw auger device can be poured directly into the ground so that the foundation construction can be done more firmly and quickly. It is about one design.
일반적으로 건물의 신축공사를 할때에는 지반을 일정 깊이로 파낸후 모래, 자갈, 시멘트 등이 혼합된 콘크리트액을 타설하여 기초공사를 견고하게 하여야 한다.In general, when constructing a new building, the foundation should be strengthened by digging the ground to a certain depth and then pouring concrete solution mixed with sand, gravel, and cement.
그런데 건축하려는 땅의 면적 전체를 그대로 깊이 파내려갈 경우에는 주벽의 흙이 쉽게 무너져 내리기 때문에 기초공사시 상당한 위험이 따르며 이를 예방하기 위해 방벽을 설치하고 버팀목 등으로 괴는등 가설작업을 하여야 되는데 따른 공기소모와 인력소모가 막대하였다.However, when digging the entire area of the land to be built as it is, the soil of the main wall easily collapses, so there is considerable risk in the foundation work, and in order to prevent this, it is necessary to install the barriers and squeeze them with supports, etc. And manpower consumption was enormous.
따라서 상기한 문제점을 해소하고자 개발되어 현재 사용되고 있는 공법은 외주면에 스크류 날개가 환설된 오거봉을 전동기로 돌려서 건축하고자 하는 지반의 둘레에 구멍뚫기 작업을 완료한후 구멍속으로 콘크리트액을 타설하여 콘코리트 방벽을 먼저 형성 하였으며, 그후 콘크리트 방벽의 내면적에 있는 흙을 퍼내어 지반공사를 하였다.Therefore, the method developed and currently used to solve the above problems is to rotate the auger rods with the screw blades on the outer circumference with an electric motor to complete the perforation work around the ground to be built, and then cast concrete solution into the holes. The litt barrier was formed first, and then the soil in the inner surface of the concrete barrier was excavated and grounded.
그러나 이와같은 공법을 위해 사용되고 있는 종래의 기계장치는 지반에 구멍을 뚫는 스크류 오거장치와 콘크리트를 타설하는 펌핑장치로 나누어져 있어서 스크류 오거장치의 스크류봉을 지반에 박았다가 빼내야만 콘크리트액을 타설할수 있는바 이와같이 나누어진 2 개의 장치를 개별적으로 사용할 경우 다음과 같은 문제점이 있다.However, the conventional machinery used for this process is divided into a screw auger for drilling holes in the ground and a pumping device for placing concrete, so that the screw rod of the screw auger can be poured into the ground before removing the concrete liquid. There are the following problems when using two separate devices separately.
첫째 ; 종래의 스크류 오거장치는 지반에 구멍을 뚫는 기능밖에 없으며, 오거봉을 지반에 그대로 박을 경우에는 나중에 오거봉을 뽑을때 오거봉의 날개에 부딪치는 주벽의 흙이 쉽게 무너져(부서져)내려 막히게 된다.first ; Conventional screw auger device only has a function of drilling a hole in the ground, and when the auger rod is put into the ground, the soil of the main wall hitting the wings of the auger rod is easily collapsed (broken) and blocked when the auger rod is pulled out later. .
따라서 이를 방지하기 위해 종래에는 오거봉을 지반에 박을때 물을 함께 주입하면서 직업 하였는바 이는 상기 문제점은 해결할 수 있으나 오거봉을 박을때 배토되는 흙이 물과함께 범벅이되어 진흙으로 변하기 때문에 이와같이 배토되는 진흙의 처리작업이 힘든 문제점이 있다.Therefore, in order to prevent this, in the past while injecting the auger rods into the ground was injected with water, which can solve the problem, but when the soil is thrown away when the auger rods are bumped with water turns into mud. Thus, there is a problem that the treatment of the clay to be covered is difficult.
둘째 ; 오거봉을 빼내고 콘크리트액을 주입할때 다량의 흙이 부서져 내리면서 주입되는 콘크리트액속에 섞이게되고, 이때 기포가 발생하여 양생된 콘크리트의 강도가 약하게 되는 문제점이 있으며, 또한 콘크리트액의 양생시 주변의 흙에 수분이 많아서(오거봉을 박을때 주입한 물로인해) 콘크리트의 양생시간이 오래 걸리게 되는 문제점이 있었다.second ; When removing the auger rod and injecting the concrete solution, a large amount of soil is broken down and mixed into the injected concrete liquid, and there is a problem in that bubbles are generated and the strength of the cured concrete is weakened. There was a problem that the curing time of the concrete takes a long time due to the moisture in the soil (injected by the auger rods).
본고안은 상기와 같은 종래 장치의 문제점을 감안하여 오거봉을 지반에 박은후 오거봉을 뽑음과 동시에 콘크리트액을 주입할수 있도록 하므로서 작업의 신속 용이함과 견고한 기초공사를 행할수 있도록 한 것인바 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.In view of the problems of the conventional apparatus as described above, this proposal is to be able to perform a quick and easy work and solid foundation work by putting the auger rods into the ground and then injecting the concrete liquid at the same time. When described in detail by the drawings as follows.
외주면에 스크류 날개(2)가 환설되고 하단에 발톱(3)이 설치된 오거봉(1) 을 상측의 축삽지부(4)에 의해 전동기의 축에 끼울수 있도록 한 것에 있어서 하우징(6) 내에서 회동되는 거플링(5) 의 축(5a)을 축삽지부(4) 에 끼우되 하우징(6) 일측에는 콘크리트 펌프의 호스(14)가 연결되는 유입구(7) 를 형성하고 커플링(5) 의 주벽에는 유입구(7) 와 일치되는 부위에 요홈(8) 을 환설한후 내부의 유통공(10) 과 통하도록 통공(9) 을 수개 형성하며, 오거봉(1) 의 내부에는 유통공(10) 과 통하는 콘크리트 유통관(11) 을 내설하되 그 배출구(12) 를 오거봉(1) 하부에 형성하고 커버(13) 를 설치하여 된 것으로서 도면중 미설명 부호(15) 는 베어링이고, (5b) 는 커플링(5) 의 축삽지부이다.Rotating in the housing 6 in which the auger rod 1 with the screw blade 2 installed on the outer circumferential surface and the claw 3 provided at the lower end thereof can be fitted to the shaft of the motor by the upper shaft inserting portion 4. The shaft 5a of the gripping ring 5 to be inserted into the shaft inserting portion 4 is formed at one side of the housing 6 to form an inlet 7 to which the hose 14 of the concrete pump is connected, and the main wall of the coupling 5. There is formed a plurality of through-holes (9) to pass through the groove (8) in the same area as the inlet (7) to communicate with the distribution hole (10), the inside of the auger rod (1) distribution hole (10) The concrete distribution pipe (11) communicating with the interior of the outlet 12 is formed in the lower auger rod (1) and the cover 13 is installed, the reference numeral 15 in the drawing is a bearing, (5b) is It is a shaft insertion part of the coupling 5.
이와같이 형성된 본고안은 전동기의 축에는 커플링(5) 의 축삽지부(5b) 를 끼우는 것이고, 커플링(5) 의 축(5a) 에는 오거봉(1) 의 축삽지부(4) 를 끼워 전동기의 동력이 커플링(5) 을 통해 오거봉(1) 에 전달되게 한 것으로서 이러한 본고안을 이용하여 작업을 실시하는 과정을 설명하면 다음과 같다.In this way, this invention is to insert the shaft insertion portion 5b of the coupling (5) to the shaft of the motor, and to insert the shaft insertion portion (4) of the auger rod (1) to the shaft (5a) of the coupling (5) When the power is transmitted to the auger rod (1) through the coupling (5) will be described the process of performing the work using this subjective as follows.
전동기의 동력을 이용하여 본고안의 오거봉(1) 을 박으면 통상의 오거봉과 같이 발톱(3) 이 지반을 파고들면서 흙이 스크류날개(2) 의 회전을 따라 지반위로 올라오게 되는데, 이때 본고안은 종래와 같이 물을 주입하지 않고 작업을 하므로 스크류날개(2) 에 의해 배토된 흙의 처리가 매우 용이하다.When the auger rods (1) in the present case are driven using the power of the electric motor, the soil will rise on the ground along the rotation of the screw blades (2) while the claws (3) are dug into the ground as in the conventional auger rods. Since the design works without injecting water as in the prior art, it is very easy to treat the soil disposed by the screw blades 2.
그리고 제4도 (a) 와같이 오거봉(1) 이 원하는 깊이만큼 지반을 파고 들어간 후에는 콘크리트 펌프를 가동시켜서 콘크리트액을 호스(14) 를 통해 하우징(6) 의 유입구(7) 로 주입시킨다.After the auger rod 1 digs the ground to the desired depth as shown in FIG. 4 (a), the concrete pump is operated to inject the concrete liquid into the inlet 7 of the housing 6 through the hose 14. .
그러면 콘크리트액은 유입구(7) 와 일치된 커플링(5) 의 요홈(8) 으로 유입된후 사방에 형성된 통공(9) 과 유통공(10) 을 통해 오거봉(1) 내부에 설치된 유통관(11) 으로 원활히 유입되는 것이며, 이와같이 유통관(11) 으로 유입된 콘크리트액은 배출구(12) 를 통해 강한 압력으로 분사가 된다.Then, the concrete liquid flows into the recesses 8 of the couplings 5 coinciding with the inlets 7, and then flows into the auger rods 1 through the through holes 9 and the distribution holes 10. 11) is smoothly flowed into, the concrete liquid introduced into the distribution pipe 11 in this way is injected at a strong pressure through the outlet (12).
이때 배출구(12) 에는 하향된 커버(13) 가 설치되어 있으므로 배출구(12) 를 통해 분사되는 콘크리트액은 발톱(3) 에 의해 뚫린 구멍 하단부에서 부터 채워지게 되며, 이와같이 배출구(12) 를 통해 콘크리트액을 분사하면서 오거봉(1) 을 서서히 뽑아내게 되면 제4도 (b)와 같이 오거봉(1) 이 뽑히는 즉시 배출구(12) 로 분사되는 콘크리트액이 뚫린구멍을 신속히 채우게 되므로 콘크리트에 흙이 섞이지 않게되어 견고하게 양생되는 기초공사를 이룰수 있다.At this time, since the downward cover 13 is installed in the outlet 12, the concrete liquid sprayed through the outlet 12 is filled from the lower end of the hole drilled by the claw 3, and thus the concrete is discharged through the outlet 12. When the auger rod 1 is slowly pulled out while spraying the liquid, as soon as the auger rod 1 is pulled out, as shown in FIG. Do not mix, can achieve a solid foundation curing.
이와같이 본고안은 오거봉(1) 을 박을때 배토되는 흙의 처리가 용이하고 지반에 박은 오거봉(1) 이 지반의 구멍 외벽을 막고있는 상태에서 (오거봉이 지반에 박혀있는 상태에서) 오거봉(1) 의 내부에 설치된 유통관(11) 을 통해 콘크리트를 주입 분사함과 동시에 오거봉(1) 을 뽑아내므로 종래와 같이 오거봉을 완전히 뽑은후 콘크리트를 주입시키는 것에 비해 작업이 신속하고 수월 하면서도 주입되는 콘크리트에 흙이 별로 섞이지 않게 되므로 기초공사되는 콘크리트벽의 강도가 매우 견고하게 되는 것으로서 기초공사에 따르는 공사기간 단축과 인력소모를 최대한 줄일수 있는 매우 유용한 고안인 것이다.In this way, this paper is easy to dispose of soil that is deposited when the auger rod (1) is put in place, and the auger rod (1) embedded in the ground is blocking the outer wall of the ground hole (with the auger rod embedded in the ground). Injecting and spraying concrete through the distribution pipe 11 installed inside the auger rod 1, and simultaneously extracting the auger rod 1, the operation is quicker than injecting concrete after completely removing the auger rod as in the prior art. Soil is not very mixed with the concrete to be injected, but the strength of the concrete wall is very solid, which is a very useful design that can reduce the construction period and manpower consumption according to the foundation work as much as possible.
