Abstract
Description
본 발명은 항만의 구조물 구축시 해저면의 준설공사에 사용되는 기초사석을 침하 다짐함에 있어서 그 시공기간을 단축하고 특히 경제적인 시공수단을 제공하고 자 안출된 항만구조물구축을 위한 해저면의 기초사석침하장치에 관한 것이다.The present invention shortens the construction period in the settlement of the foundation stones used for dredging the bottom of the sea when constructing the harbor structure, and in particular, provides an economical means of construction and provides a foundation structure of the sea bottom for the construction of the port structure. It relates to a settlement device.
방파제 및 물양장을 포함하는 부두 등 제반 항만 구조물의 구축시 기초공사로 수행되는 해저면의 준설공사는 기초사석을 투입하여 침하시키면서 다져주는 것으로써 항만 구조물의 견실한 시공을 위한 지극히 중요한 선행작업이다.The dredging work on the sea floor, which is carried out as a foundation for the construction of all port structures including breakwaters and water docks, is a very important prerequisite for the robust construction of the port structures by inserting and laying the foundation stones.
특히 국내 항만구조물 축조지점은 대부분 연약 해성점토층이 깊게 존재하므로 항만구조물이 그 기능을 안전하게 수행하기 위해서는 해저면의 준설작업은 필연적이다.In particular, most of Korea's port structure construction sites have deeply dissolved marine clay layers, so dredging of the sea bottom is inevitable in order for port structures to perform their functions safely.
준설작업은 준설선을 이용하여 구조물이 위치하는 해저면의 해성점토층을 소정의 깊이로 제거한 다음, 이에 사석 등을 투입하고 다짐공법으로 침하시키는 작업이다. 그리고 이와같이 침하 다짐된 상기 기초사석위에 케이슨을 설치하고 케이슨 위에 콘크리트를 타설하여 물양장 등을 확보하는 한편, 육지쪽을 매립하여 부두 등을 구축한다.Dredging work is to remove the marine clay layer on the sea floor where the structure is located by using a dredger to a predetermined depth, and then insert sandstones and sink it by the compaction method. In addition, the caisson is installed on the settled foundation stone thus settled, and concrete is placed on the caisson to secure a water tank and the like, while the land is buried to build a pier.
그러나 상기 준설작업에 있어서 현재 지적되고 있는 문제점은 비용과 공사기간이 과다하게 소요된다는 점이다. 특히 침하작업의 불량으로인한 부두하역의 크레인 손상 및 균열 등 상당한 경제적 피해가 발생되고 있다. 즉, 지금까지의 침하작업은 기초사석 위에 케이슨을 거치한 다음, 케이슨 위에 재하블록(통상40∼50톤, 폭 2.5M, 길이 5M, 높이 1.5M)을 무수히 쌓아 2∼3개월 정도 방치함으로써 그 하중에 의해 기초사석이 다져지도록 하고 있다. 이는 지극히 재래적인 수단으로써 침하불량 및 공사기간의 지연은 물론 재하블록의 제작 및 재하블록의 설치 내지는 제거에 따른 엄청난 인력과 경제적 손실을 초래하고 있는 것이다. 또한 케이슨의 설치후 케이슨위에 재하블록을 재치함으로써 케이슨에 무리가 가해짐은 물론 케이슨 법선관리의 어려움에 따른 시공성 및 안전성의 불리함을 감수하고 있다.However, the problem currently pointed out in the dredging operation is that the cost and construction period is excessive. In particular, significant economic damage has occurred such as crane damage and cracking at dock loading due to poor settlement work. In other words, the sinking work so far is carried out by placing a caisson on the foundation stone, and then stacking a number of loading blocks (typically 40-50 tons, width 2.5M, length 5M, height 1.5M) on the caisson and leaving it for about 2 to 3 months. The basic stone is compacted by the load. This is a very conventional means, which causes not only poor settlement and delay of construction period, but also enormous manpower and economic loss due to the manufacture of the loading block and the installation or removal of the loading block. In addition, by installing the loading block on the caisson after the installation of the caisson, the caisson is exerted, and the construction and safety of the caisson normal management are disadvantageous.
본 발명은 기초사석 축조후 다짐판을 갖는 강관을 구비하여 상기 강관에 유압해머를 이용하여 타격하는 충격다짐구조를 제공함으로써 기초사석의 침하를 용이하면서도 극히 양호하게 수행하고 이에따른 우수한 시공성과 경비의 절감, 그리고 케이슨 법선관리의 용이함에 따른 안정성을 효과적으로 유지하고자 한다.The present invention is provided with a steel pipe having a compaction plate after the basic stone construction to provide a shock compaction structure to hit the steel pipe by using a hydraulic hammer to perform the settlement of the basic stone easily and extremely good and accordingly excellent construction and cost We will effectively maintain the stability of the savings and ease of caisson normal management.

준설공사에서 기초사석(100)을 침하시킴에 있어서, 준설선(200)에 유압해머 (11) 및 해머가이드(12)를 갖는 유압해머장치(10)를 구비하고, 상기 해머(11)로 타격되는 강관(20)을 해머가이드(12)에 수직으로 연동, 구성하는 한편, 강관(20)의 하단에는 기초사석침하용 다짐판(21)을 일체로 그리고 넓게 형성하여된 구조이다.In sinking the foundation stone 100 in the dredging construction, the dredger 200 is provided with a hydraulic hammer device 10 having a hydraulic hammer 11 and a hammer guide 12, and is hit by the hammer 11 While the steel pipe 20 is interlocked and configured perpendicularly to the hammer guide 12, the lower end of the steel pipe 20 has a structure formed by integrally and widely forming the compaction plate 21 for basic basin settlement.
도면부호중(30)은 케이슨, (40)은 콘크리트 타설층, (50)은 매립부를 나타낸것이다.Reference numeral 30 denotes a caisson, 40 denotes a concrete pouring layer, and 50 denotes a buried portion.
이와같이 구성된 본 발명은 통상의 준설공사에서 수행하는 작업으로 먼저 구조물이 위치하는 해저면을 준설선 등을 이용하여 연약 해성점토층을 제거한 다음, 그 제거된 요입부에 기초사석(100)을 투입한다. 그러나 본 발명은 이와같은 기초사석(100)을 일시에 투입하지 않고 적량(해저면에서 두께 약 1.5M)으로 반복 투입하는바, 즉, 본 발명에서는 투입된 기초사석(100)의 해저면으로부터 두께가 약 1.5M에 이르면 본 발명에 의해 침하, 다짐작업을 수행하게 되며 다시 그 위에 1.5M 정도의 두께로 기초사석(100)이 적층되면 재 침하작업을 수행하는 등, 반복 침하작업으로 수행하게 된다.In the present invention configured as described above, the work performed in a typical dredging construction is to first remove the soft marine clay layer using a dredger or the like on the sea floor where the structure is located, and then insert the foundation stone 100 into the removed recess. However, in the present invention, the basic stone 100 is repeatedly added in an appropriate amount (about 1.5M thick at the bottom of the sea) without being put at a time, that is, in the present invention, the thickness from the sea bottom of the injected basic stone 100 When it reaches about 1.5M, the settlement and compaction work is performed according to the present invention, and when the basic stone 100 is laminated to the thickness of about 1.5M thereon, re-sedimentation work is performed, such as repeated settlement.
본 발명의 유압해머장치(10)는 준설선(200)에 탑재되어 있어 해안의 어느곳이든 장소에 구애받지 않고 작업이 가능하며 또 극히 효과적인 기동력을 발휘한다.Hydraulic hammer device 10 of the present invention is mounted on the dredger 200, which can work regardless of the place anywhere on the coast and exhibits extremely effective maneuverability.
유압해머장치(10)의 해머가이드(12)에는 강관(20)이 연동되어 있는바, 물론 이 강관(20)은 상기 해머가이드(12)상에서 상,하 유동가능하게 결합된다. 전술한 바와같이 연약 해성점토층이 제거된 해저면에 기초사석(100)이 투입되면 기초사석 (100)의 상면에 기초사석침하용 다짐판(21)을 밀착하고 유압해머장치(10)를 가동한다. 유압해머장치(10)의 가동에 의해 해머(11)가 해머가이드(12)에 안내되면서 상,하 반복 작동하여 강관(20)을 연속적으로 타격 함에 따라 강관(20)저부에 일체로 구성된 기초사석침하용 다짐판(21)이 기초사석(100)상면을 타격하게 되고 또 이와같은 타격이 반복적으로 수행됨에 따라 기초사석(100)은 극히 효과적으로 침하되게 된다. 또한 기초사석침하용 다짐판(21)은 넓게 구성되어 기초사석(100)의 타격범위가 크게 확대되며 또 이와같은 타격수단은 상기한 바와같이 재자리에 수회 반복하는 것과함께 평면상에서 상하좌우로 위치를 이동시켜 가면서 기초사석(100)의 상면전체를 침하시키게 된다. 그리고 이와같은 위치의 이동은 관용수단인 유압해머장치 (10)의 붐대를 조작함으로써 간단히 수행할 수 있다. 즉, 본 발명은 기초사석(100)를 적량 투입한 후 유압해머장치(10)를 가동하여 기초사석(100)의 상면 전체를 반복적으로 타격하여 침하, 다짐하고 이와같이 침하, 다짐된 기초사석(100)위에 다시 적량의 기초사석을 투입하여 동일한 방법으로 침하작업을 수행하는 등, 이를 수회 반복 작업함으로써 소망하는 높이의 기초사석(100)을 구축하게 된다.The steel pipe 20 is linked to the hammer guide 12 of the hydraulic hammer device 10, of course, the steel pipe 20 is coupled to the upper and lower flow on the hammer guide 12. As described above, when the basic stone 100 is introduced into the sea bottom from which the soft marine clay layer has been removed, the compaction plate 21 for the basic stone settlement is in close contact with the upper surface of the basic stone 100 and the hydraulic hammer device 10 is operated. . Basic hammer is integrally formed on the bottom of the steel pipe 20 as the hammer 11 is guided to the hammer guide 12 by the operation of the hydraulic hammer device 10 and repeatedly hits the steel pipe 20 continuously. As the settlement compaction plate 21 hits the upper surface of the basic stone 100 and the hitting is repeatedly performed, the basic stone 100 is extremely effectively settled. In addition, the basic settling plate compaction plate 21 is configured to be wide, the range of impact of the basic stone 100 is greatly enlarged, and such a hitting means is positioned up, down, left and right on the plane with repeating several times in place as described above. While moving it is to settle the entire upper surface of the basic stone 100. And the movement of such a position can be performed simply by operating the boom of the hydraulic hammer apparatus 10 which is a usual means. That is, according to the present invention, after the proper amount of the basic stone 100 is put into operation, the hydraulic hammer device 10 is operated to repeatedly hit the entire upper surface of the basic stone 100 so as to settle and compact and thus settle and compact the basic stone 100 By putting the appropriate amount of foundation stone again on the above to perform the sinking work in the same manner, such as by repeating this several times to build the foundation stone 100 of the desired height.
기초사석(100)의 구축이 완료되면 통상의 수단인 해상 대형크레인을 이용하여 기초사석(100)위에 모래 등이 채워지는 케이슨(30)을 거치하는 한편, 케이슨 (30)위에 상치콘크리트를 타설하고 이어 육지쪽을 매립한다.When the construction of the foundation stone 100 is completed, the caisson 30 is filled with sand or the like on the foundation stone 100 using marine large-scale crane, which is a conventional means, while placing the concrete concrete on the caisson 30 Then landfill the land.
본 발명은 기초사석의 투입과 동시에 침하, 다짐작업을 수행함으로써 기초사석의 구축을 극히 용이하게 완료하게 된다. 이는 재하블록의 하중을 이용하여 장기간 방치하는 종래의 수단에 비하여 공사기간을 크게 단축함은 물론 막대한 시공비의 절감효과를 갖는다. 또한 케이슨을 거치하기 전에 침하를 발생시키므로 종래와 같이 법선의 정열 등 법선관리를 위한 규준틀 등의 사용이 배제됨에 따라 케이슨 법선관리가 용이하고 이에따른 우수한 시공성 및 안정성을 확보한다.The present invention is very easy to complete the construction of the basic stone by performing the settlement and compaction work at the same time as the input of the basic stone. This significantly shortens the construction period as compared to the conventional means of leaving the load for a long time using the load of the loading block, and has a significant construction cost reduction effect. In addition, since the settlement occurs before the caisson is mounted, the use of the standard frame for normal management such as the alignment of the normal is excluded, so the caisson normal management is easy, and thus excellent construction property and stability are secured.
