본 발명은 바닷가의 갯벌이나 모래사장과 같이 지반이 연약한 연약지반을 천공하기 위한 연약지반 천공장치에 관한 것으로서, 더욱 상세하게는 고압으로 분사되는 고압수의 압력과 회전날개에 형성된 분쇄부에 의해 연약지반을 천공할 수 있도록 하기 위한 것이다.The present invention relates to a soft ground perforation device for drilling a soft ground, such as a beach tidal flat or sandy beach, more specifically, soft by the crushing portion formed in the pressure of the high-pressure water sprayed at high pressure and the rotary blades It is to make the ground perforated.

일반적으로 바닷가의 갯벌이나 하천 또는 강가와 같이 지반이 연약한 연약지반 을 천공할 경우에는 대형드릴러로서 천공하게되는데, 이 대형드릴은 천공하는 부분이 때로는 강바닥이나 바다바닥과 같이 깊은 지점까지 천공해야 할 경우가 있기 때문에 드릴의 길이가 매우 길어야하며, 드릴의 길이가 같기 때문에 종래의 대형드릴장치는 거대한 크기와 무게를 가지고 있기 때문에 다수의 천공기를 동시에 작업하는 것이 불가능하고 천공속도 또한 30~60r.p.m정도의 저속회전이며, 깊은 지점을 천공할 경우에는 드릴의 길이가 길어지게 되는데 그 길어지는데도 한계가 있어 깊은 곳의 천공은 사실상 불가능한 상태이다.In general, when drilling a soft ground such as tidal flats, rivers, or rivers where the ground is soft, it is drilled as a large drill, which is sometimes drilled to a deep point such as a river bed or a sea floor. Since the drill length should be very long, and the drill length is the same, the conventional large drill apparatus has a huge size and weight, so it is impossible to work with multiple drill machines at the same time, and the drilling speed is also about 30 to 60 r.pm. It is a low speed rotation of, and when the deep point is drilled, the length of the drill becomes long, but the length of the drill is limited, and the deep hole is practically impossible.

또한, 상기 드릴의 길이가 길기 때문에 드릴회전시 편심이 커지게되어 천공되는 구멍의 형태와 크기 및 수직도를 원하는데로 얻을 수 없게 되는 문제가 있다.In addition, since the length of the drill is long, there is a problem that the eccentricity is increased during the rotation of the drill, so that the shape, size and verticality of the hole to be drilled cannot be obtained as desired.

따라서 본 발명은 상기와 같은 종래의 제반 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 바지선에 설치된 크레인의 와이어로서 본 발명을 매달아 강바닥이나 바다바닥 또는 갯벌등에 위치시킬 수 있도록 한뒤에, 본 발명의 천공장치에서 100~500kg/㎠정도의 고압수를 분사시켜 작업하고 천공 및 확경작업시 통상 200~400kg/㎠를 분사시켜 강바닥이나 바다바닥 또는 갯벌과 같이 연약한 지반이 파헤쳐지도록 하면서, 그와 동시에 연약지반 폐쇄수단을 구비한 회전날개로 상기 고압수에 의해서 파헤쳐지는 토사를 다시한번 미분쇄하면서 중앙부측의 지반을 파헤치고, 고압이 토출장치로서 상기 천공과정에서 발생하는 미분쇄토사와 물을 토출시킬 수 있도록 하는 연약지반 천공장치를 제공하기 위한 것이다.Therefore, the present invention is to solve the conventional problems as described above, the object of the present invention is to hang the present invention as a wire of a crane installed on a barge so that it can be placed on the river bottom or sea bottom or tidal, etc., the perforation of the present invention It works by spraying high pressure water of 100 ~ 500kg / ㎠ from the device and sprays 200 ~ 400kg / ㎠ usually during drilling and expansion work so that soft ground such as river bed, sea bottom or tidal flat is dug, and at the same time A rotary blade provided with a closing means can dig the ground of the central part while pulverizing the soil dug by the high-pressure water once again, and the high-pressure discharge device can discharge the pulverized sand and water generated in the drilling process. It is to provide soft ground fabric factory.

먼저, 제5도에서와같이 바지선(60)에 설치된 크레인(63)으로 본 발명의 연약지반천공장치(100)를 매달아서 이 천공장치(100)를 연약지반(70)에 내려 놓으면서 천공펌프(61)와 토출펌프(62) 그리고, 임펠러(40)를 구동시킨다.First, as shown in FIG. 5 by hanging the soft ground drilling device 100 of the present invention with a crane 63 installed on the barge 60, while lowering the drilling device 100 on the soft ground 70 (punch pump ( 61, the discharge pump 62, and the impeller 40 are driven.

상기 점성토 분쇄용 임펠러는 지면에 대면되는 표면에 凹凸 또는 돌기부에 형성되어 있어 점성토을 파헤치고 잘라서 측면으로 회전에 의한 주위로의 방출이 쉽게 되도록 한다.The impeller for crushing the clay is formed on the surface or projections on the surface facing the ground to dig and cut the clay to make it easier to release to the surroundings by rotation to the side.

상기와 같이, 천공펌프(61)와 토출펌프(62) 그리고 임펠러를 구동시킴에 따라 고압수는, 천공펌프로부터 고압수흡입관(31)을 통해 유입되어 그와 연결된 고압수통로(11)를 거쳐 수직분사노즐(21)과 경사분사노즐(22)을 통해 지면으로 분사된다.As described above, as the puncture pump 61, the discharge pump 62 and the impeller are driven, the high pressure water flows from the puncture pump through the high pressure water suction pipe 31 and is connected to the high pressure water passage 11 connected thereto. It is sprayed to the ground through the vertical spray nozzle 21 and the inclined spray nozzle 22.

상기와 같이 고압수를 지면으로 100-500kg/㎠정도의 고압으로 분사함에 따라 연약지반이 파헤쳐지게되며, 이렇게 파헤쳐지는 토사는 경사노즐과 함께 임펠러(40) 하방측을 파헤치고 있는 임펠러(40)의 분쇄부(44)에 의해 미분쇄되어 흙탕물 형태로 된다.As described above, the soft ground is dug as the high pressure water is injected into the ground at a high pressure of about 100-500kg / cm 2, and the soil to be dug up is dug up the impeller 40 with the inclined nozzle.

상기와 같이 연약지반을 개량하고자 할 경우에는 위에서 설명한 바와 같이 연약지반을 천공한뒤에 천공펌프(61)와 토출펌프(62) 그리고 임펠러(40)의 기동을 정지시키고 천공펌프(61)나 토출펌프(62)를 선택하거나 각각의 펌프(61), (62)를 동시에 이용하거나하여 약액을 주입을 주입시키면서 천공장치(100)를 들어올리면 먼저 천공된 구멍으로 약액이 주입되면서 응고되어 연약지반을 개량할 수 있는 것이다.When the soft ground is to be improved as described above, after drilling the soft ground as described above, the start of the drilling pump 61, the discharge pump 62, and the impeller 40 is stopped, and the drilling pump 61 or the discharge pump ( Select 62) or use the respective pumps 61 and 62 at the same time to lift the puncturing device 100 while injecting the injection of the chemical solution, and then the chemical liquid is first injected into the perforated hole to solidify and improve the soft ground. It can be.

이상에서 살펴본 바와 같은 본 발명은, 고압수와 임펠러로서 연약지반을 동시에 지반분쇄하면서, 고압수 분사에 의해 파헤쳐지는 토사를 임펠러로 미분쇄한뒤에, 이를 장치외부로 아울러 토출시킬 수 있도록하는 수단을 구비한 천공장치를 크레인으로 매달아 작업할 수 있도록 되어 있어, 종래의 드릴보다 소형이면서도 천공능력이 대폭 향상된 장점이 있다.As described above, the present invention is provided with a means for pulverizing soil ground by high pressure water injection and impregnating the soft soil as impeller, and simultaneously discharging it to the outside of the apparatus while simultaneously grinding the soft ground as high pressure water and impeller. It is possible to work by hanging the agar mill with a crane, there is an advantage that the drilling capacity is significantly improved compared to the conventional drill.

따라서 여러대의 천공장치를 이용하여 대량 작업이 가능하여 공사기간을 대폭 단축시킬 수 있는 매우 특출한 효과외에도, 천공장치가 지면에 맞닿은 상태에서 작업이 이뤄지기 때문에 천공, 분쇄작업이 장치외부와 차단된 상태로 작업이 이루어져 작업장 주위를 오염시키거나 지저분하게 하지 않고도 깨끗하게 작업이 가능하며 환경보호에도 이바지하는 효과가 있다.Therefore, in addition to the very special effect that can greatly reduce the construction period by using a large number of fabric mills, the drilling is performed in a state where the drilling device is in contact with the ground. As the work is carried out in a state, it is possible to work cleanly without contaminating or messing around the work place, and it also contributes to environmental protection.
