Description

말뚝의 보강구조물{REINFORCEMENT STRUCTURE FOR PILE}Pile reinforcement structure {REINFORCEMENT STRUCTURE FOR PILE}

본 발명은 토목 분야에 관한 것으로서, 상세하게는 말뚝의 구조에 관한 것이다.The present invention relates to the field of civil engineering, and in particular, to the structure of the pile.

지반에 구조물의 기초를 형성하기 위한 말뚝의 시공방법은 크게, 공장제작말뚝을 항타에 의해 근입하는 방법과, 천공 홀에 배근을 설치하고 콘크리트를 현장타설하는 방법으로 나누어 볼 수 있다.The construction method of piles to form the foundation of the structure on the ground can be largely divided into the method of entering the factory manufacturing pile by driving, and the method of installing the reinforcement in the drilling hole and placing the concrete in the field.

전자인 항타공법은 말뚝으로서 상하단에 트임부가 형성된 속이 빈 관 구조의 강관이나 PHC말뚝을 사용하는데, 이러한 구조의 말뚝을 항타하는 경우 토사가 하단의 트임부를 통해 유입되다가 어느 시점부터는 하부 지반에 압밀이 일어나 더 이상 토사의 유입이 발생하지 않으므로(이를 현장에서는 '바닥이 막힌다.'라고 표현한다), 안정적인 기초 구조물을 형성할 수 있다.The former anti-punching method uses a hollow tube structure or a PHC pile formed with upper and lower trims as piles. When the piles are driven, the soil is introduced through the lower trims and at some point consolidation is applied to the lower ground. As no more inflow of soil occurs (expressing 'floor clogging' in the field), a stable foundation can be formed.

이러한 항타공법은 시공의 편의성 및 구조의 안정성이 우수하다는 장점이 있지만, 시공 시 항타에 의한 소음이 크게 발생한다는 단점이 있다.This anti-taking method has the advantage of excellent construction convenience and stability of the structure, but has the disadvantage that a large noise generated by the driving during construction.

후자인 현장타설공법은 위와 반대의 장단점을 갖는다.The latter, on-site casting method has the opposite advantages and disadvantages.

한편, 최근 항타공법에서 말뚝의 하단에 말뚝의 직경에 비해 더 큰 직경을 갖는 슈(선단 확장슈)를 장착하여 시공하는 방식이 개발된바 있는데, 이는 말뚝의 슈(선단)의 면적이 넓어짐에 따라 더욱 큰 선단지지력을 확보할 수 있으므로, 기초 구조물의 안정성을 증대할 수 있고, 이에 따라 말뚝의 수를 줄일 수 있어 공사비용을 절감할 수 있다는 장점이 있다.On the other hand, in the anti-puncture method has been developed to install a shoe (tip expansion shoe) having a larger diameter than the diameter of the pile at the bottom of the pile, which is because the area of the shoe (tip) of the pile is widened Accordingly, since it is possible to secure a greater tip support capacity, it is possible to increase the stability of the foundation structure, thereby reducing the number of piles, there is an advantage that can reduce the construction cost.

그런데 이러한 종래의 공법에 있어서는, 선단 확장슈를 말뚝의 하단에 장착하는 구조에 관한 연구가 미흡하여 다음과 같은 문제가 지적되어 왔다.However, in such a conventional method, studies on the structure of attaching the tip extension shoe to the lower end of the pile have been insufficient, and the following problems have been pointed out.

첫째, 선단 확장슈를 미리 공장에서 말뚝의 하단에 장착하여 현장으로 이동하는 경우에는, 운반 및 보관이 불편하다는 점이다.First, when the tip expansion shoe is mounted to the bottom of the pile in advance in the factory and moved to the site, transportation and storage are inconvenient.

둘째, 현장에서 선단 확장슈를 용접 등에 의해 장착하는 경우에는, 그 작업에 소요되는 수고와 시간이 지나치게 많이 소요된다는 점이다.Second, in the case where the front end shoe is mounted by welding or the like, the labor and time required for the work are too much.

셋째, 시공을 위하여 장비에 의해 말뚝을 일으켜 세우다가 장착된 확장슈가 파손되기 쉽다는 점이다.Third, it is easy to damage the expansion shoe mounted after raising the stake by the equipment for construction.

본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 선단 확장슈의 장착에 소요되는 수고와 시간을 절감할 수 있고, 시공시 확장슈의 파손 우려가 없도록 하는 말뚝의 보강구조물을 제시하는 것을 그 목적으로 한다.The present invention was derived to solve the above problems, to reduce the effort and time required for the installation of the tip expansion shoe, and to propose a reinforcement structure of the pile so that there is no fear of damage to the expansion shoe during construction For that purpose.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 이하에 도시된 바와 같이, 본 발명에 의한 말뚝의 보강구조물(A)은 기본적으로, 관 형상의 말뚝 본체(10)의 하단 트임부에 끼움결합하도록 상측으로 돌출된 돌출결합부재(100); 말뚝의 외경보다 큰 외경을 갖는 확장슈를 형성하도록, 돌출결합부재(100)의 하부에 결합한 확장슈 형성부재(200);를 포함하여 구성된다.As shown in Figure 1, the reinforcement structure (A) of the pile according to the present invention is basically, a protruding coupling member 100 protruding upward to fit the lower trimming portion of the tubular pile body (10). ; It is configured to include; expansion shoe forming member 200 coupled to the lower portion of the protruding coupling member 100 to form an expansion shoe having an outer diameter larger than the outer diameter of the pile.

즉, 종래와 같이 확장슈를 말뚝의 하단에 용접 등에 의해 결합하는 방식을 취하는 것이 아니라, 보강구조물에 형성된 돌출결합부재(100)가 말뚝 본체(10)의 하단 트임부에 삽입되면서 단지 끼움결합에 의해 장착되는 방식을 취하도록 한 것이다.That is, instead of taking the method of joining the expansion shoe to the lower end of the pile by welding or the like, the protruding coupling member 100 formed in the reinforcing structure is inserted into the lower trimming portion of the pile main body 10 and is merely fitted to the fitting. It is to take the manner of mounting.

이에 따라 현장에서 보강구조물(A)을 천공 홀 근처에 세워두고, 장비에 의해 말뚝(10)을 운반하여 보강구조물(A) 위에 단지 내려놓는 작업에 의해 말뚝과 보강구조물(A)의 결합을 완료할 수 있는 것이다(도 1).Accordingly, the construction of the pile and the reinforcing structure (A) is completed by placing the reinforcing structure (A) near the perforation hole in the field, carrying the pile (10) by the equipment, and simply laying it on the reinforcing structure (A). It can be done (Fig. 1).

따라서 종래와 같이 선단 확장슈의 장착에 소요되는 수고와 시간을 절감할 수 있고, 상술한 작업에 의해 보강구조물(A)이 결합한 말뚝을 다시 장비에 의해 들어올려 천공 홀에 삽입하면 되므로 시공시 확장슈의 파손 우려가 없다는 효과가 있다.Therefore, it is possible to reduce the effort and time required for the installation of the tip expansion shoe as in the prior art, and by expanding the construction work by lifting the pile combined with the reinforcing structure (A) by the above equipment and inserting it into the drilling hole. It is effective that there is no fear of damage to the shoe.

돌출결합부재(100)는 말뚝 본체(10)의 하단 내벽과의 마찰에 의해 결합하여 말뚝의 하단이 천공 홀 바닥에 이르기까지만 결합을 유지하면 되므로, 대단히 강한 결합을 이룰 필요는 없다.Protruding coupling member 100 is coupled by friction with the inner wall of the lower end of the pile body 10, so the lower end of the pile only to maintain the coupling until the bottom of the hole, it is not necessary to achieve a very strong coupling.

천공 홀 바닥에 이른 이후에는 항타에 의해 말뚝 본체(10)와 보강구조물(A)이 서로 결합하는 방향으로 힘을 받게 되기 때문이다.This is because the pile body 10 and the reinforcing structure A are forced in the direction in which the pile body 10 and the reinforcing structure A are coupled to each other by hitting the bottom of the punched hole.

이와 같은 마찰 결합이 비교적 견고하게 이루어지고, 돌출결합부재(100)와 말뚝 본체(10)의 하단의 결합작업(장비에 의해 말뚝을 들어올려 소정 위치에 내려놓는 작업)을 용이하게 수행하도록 하기 위해서는, 말뚝 본체(10)의 하단 내벽에 결합하는 부위의 폭이 상측 및 내측을 향하여 점점 좁아지도록(경사지도록) 형성된 구조를 취하는 것이 바람직하다(도 1 내지 4).Such friction coupling is made relatively firm, and in order to easily perform the coupling operation (work to lift the pile by the equipment to lower the predetermined position) of the protruding coupling member 100 and the pile body 10. , It is preferable to take the structure formed so that the width of the portion to be bonded to the lower inner wall of the pile main body 10 becomes narrower (inclined) toward the upper side and the inner side (FIGS. 1 to 4).

이하, 돌출결합부재(100)의 구조에 관한 실시예에 대하여 설명한다.Hereinafter, embodiments of the structure of the protruding coupling member 100 will be described.

돌출결합부재(100) 중 말뚝 본체(10)의 하단 내벽에 결합하는 부위가 만곡지게 형성되는 경우, 위와 같은 효과를 더욱 크게 얻을 수 있다(도 3,4).When the portion of the protruding coupling member 100 coupled to the lower inner wall of the pile body 10 is formed to be curved, the above effects can be obtained even more (FIGS. 3 and 4).

돌출결합부재(100)가 횡방향으로 설치된 판형 구조를 취하는 경우, 재료를 줄이면서도 견고한 결합을 이루는 효율적인 구조를 얻을 수 있다.When the protrusion coupling member 100 has a plate-like structure installed in the lateral direction, it is possible to obtain an efficient structure that achieves a firm coupling while reducing the material.

돌출결합부재(100)가 반원형 단면 구조를 취하는 경우, 말뚝의 결합작업시 말뚝의 하단이 최초에 정확한 위치에 도달하지 않더라도 슬라이딩에 의해 결합위치를 쉽게 찾을 수 있을 것이므로, 말뚝의 결합작업을 더욱 용이하게 수행할 수 있다는 장점이 추가된다(도 4).If the protruding coupling member 100 takes a semi-circular cross-sectional structure, even when the lower end of the pile does not initially reach the correct position during the coupling operation of the pile, it will be easier to find the coupling position by sliding, making the coupling operation easier. The advantage is that it can be done easily (Fig. 4).

돌출결합부재(100)는 한 쌍이 상호 직교하도록 설치됨으로써, 평면상 "+"자형 구조를 취하도록 하는 것이 구조적 안정성 및 작업의 편의성 측면에서 더욱 바람직하다.Protruding coupling member 100 is installed so that the pair is orthogonal to each other, it is more preferable in terms of structural stability and ease of operation to take a planar "+" shaped structure.

이하, 확장슈 형성부재(200)의 구조에 관한 실시예에 대하여 설명한다.Hereinafter, embodiments of the structure of the extension shoe forming member 200 will be described.

기본적으로 확장슈 형성부재(200)는 말뚝의 외경보다 큰 외경을 갖는 판형 구조의 밀폐부재(200a)를 포함하는 구성을 취함으로써, 일반적인 선단 확장슈의 구조를 얻을 수 있다(도 1 내지 4).Basically, the expansion shoe forming member 200 has a configuration including a sealing member 200a having a plate-like structure having an outer diameter larger than the outer diameter of the pile, thereby obtaining a structure of a general tip expansion shoe (FIGS. 1 to 4). .

나아가, 확장슈 형성부재(200)는 도 5 이하에 도시된 바와 같은 개폐식 구조를 취할 수도 있다.In addition, the expansion shoe forming member 200 may have an openable structure as shown in FIG.

즉, 확장슈 형성부재(200)는 돌출결합부재(100)의 하단 외측 단부에 결합함과 아울러, 심부에 트임부가 형성된 지지부재(210); 지지부재(210)의 하단 트임부를 개폐하도록 설치된 개폐판(220); 지지부재(210)의 저면 전단에 형성된 중앙 지지부재 힌지부(211); 일단이 중앙 지지부재 힌지부(211)에 연결된 중앙 연결부재(231); 중앙 연결부재(231)의 타단이 연결됨과 아울러, 개폐판(220)의 심부에 형성된 중앙 개폐판 힌지부(221); 지지부재(210)의 저면 양측단에 형성된 한 쌍의 양측 지지부재 힌지부(212); 일단이 한 쌍의 양측 지지부재 힌지부(212)에 각각 연결된 한 쌍의 양측 연결부재(232); 한 쌍의 양측 연결부재(232)의 타단이 연결됨과 아울러, 개폐판(220)의 중앙 개폐판 힌지부(221)보다 후방에 형성된 한 쌍의 양측 개폐판 힌지부(222);를 포함하고, 중앙 연결부재(231) 및 한 쌍의 양측 연결부재(232)의 힌지구동에 의해 개폐판(220)의 개폐구동이 이루어지는 구성을 취할 수 있다.That is, the expansion shoe forming member 200 is coupled to the bottom outer end of the protruding coupling member 100, the support member 210 is formed with a recess in the core; An opening and closing plate 220 installed to open and close the lower trimmed portion of the support member 210; A central support member hinge portion 211 formed at the front end of the bottom of the support member 210; A central connection member 231 having one end connected to the central support member hinge portion 211; A central opening and closing plate hinge portion 221 formed at the core of the opening and closing plate 220 while the other end of the central connecting member 231 is connected; A pair of both supporting member hinge parts 212 formed at both ends of the bottom of the supporting member 210; A pair of both side connecting members 232, one end of which is connected to a pair of both side support member hinges 212, respectively; And a pair of both opening and closing plate hinge parts 222 formed at a rear side of the opening and closing plate hinge part 221 of the opening and closing plate 220 and connected to the other ends of the pair of both connecting members 232. By the hinge driving of the central connecting member 231 and the pair of both connecting members 232, the opening and closing driving of the opening and closing plate 220 may be performed.

이와 같은 힌지구조로 인하여 중앙 연결부재(231) 및 한 쌍의 양측 연결부재(232)의 힌지구동에 의해 개폐판(220)의 개폐구동이 이루어지게 된다.Due to the hinge structure as described above, the opening and closing driving of the opening and closing plate 220 is performed by the hinge driving of the central connecting member 231 and the pair of both connecting members 232.

즉, 천공 홀에 대한 말뚝 본체(10)의 근입 시에는 개폐판(220)이 개방상태를 취하도록 하고(도 8), 천공 홀의 바닥에 이르러서는 개폐판(220)이 폐쇄상태를 취하도록 한 것이다(도 9,10).That is, the opening and closing plate 220 in the opening state of the pile body 10 to the drilled hole to take the open state (Fig. 8), the opening and closing plate 220 to reach the bottom of the drilled hole to take the closed state (FIGS. 9 and 10).

이는 다음과 같은 효과가 있다.This has the following effects.

첫째, 말뚝 본체(10)의 삽입 작업 중에는 개폐판(220)이 개방상태를 취하게 되므로, 천공 홀에 존재하는 그라우트 기타 유체의 부력에 의해 말뚝이 부유하여 근입 작업에 방해받지 않게 되고, 천공 홀의 바닥에 이르러서는 개폐판(220)이 폐쇄상태를 취하게 되므로, 강제로 바닥이 막히도록 함으로써 일부항타만으로도 선단지지력을 크게 확보할 수 있다.First, since the opening and closing plate 220 is opened during the insertion of the pile body 10, the pile is suspended by buoyancy of the grout or other fluid present in the drilling hole, so that the pile is not disturbed by the rooting operation and the bottom of the drilling hole. Since the opening and closing plate 220 is in a closed state, it is possible to secure the tip support force by only a few strokes by forcibly blocking the floor.

따라서 본 발명에 의한 말뚝은 선천공 일부항타방식의 공법에 적용되는 경우라도 선단지지력을 충분히 확보하도록 하여(바닥이 확실히 막히도록 하여) 안정적인 기초 구조물을 이룰 수 있고, 공사비용을 절감할 수 있도록 한다는 효과가 있다.Therefore, the pile according to the present invention, even when applied to the construction method of the partial piercing method of the boring to ensure sufficient support capacity (to ensure the floor is blocked) to achieve a stable foundation structure, and to reduce the construction cost It works.

둘째, 개폐판(220)이 원형을 유지한 상태에서 말뚝 하단 트임부를 개폐하므로, 개폐판(220) 구조의 변형으로 인한 문제의 발생 우려가 적다.Secondly, since the opening and closing plate 220 opens and closes the lower pile trim in a state in which the opening and closing plate 220 maintains a circular shape, there is little concern about a problem caused by deformation of the opening and closing plate 220 structure.

셋째, 측방에서 볼 때, 4개의 힌지에 의한 개폐구동구조를 취하므로, 자유로운 형상의 변형이 가능하여, 적치장소에서 들어올리거나 천공 홀 부근에 내려놓는 작업 시 파손의 우려가 적다.Third, since the opening and closing drive structure by four hinges is taken from the side, free deformation is possible, and there is little risk of damage when lifting from a storage place or laying down near a drill hole.

확장슈 형성부재(200)를 구성하는 지지부재(210)는 돌출결합부재(100)의 하단 외측 단부에 결합함과 아울러, 심부에 트임부가 형성된 구성을 취하는데, 이는 링형 구조에 의해 구현되는 것이 후술하는 구조와 관련하여 구조적 안정성 측면에서 바람직하다.The support member 210 constituting the extension shoe forming member 200 is coupled to the bottom outer end of the protruding coupling member 100, and takes a configuration in which a slit is formed in the core, which is implemented by a ring structure. It is preferable in terms of structural stability with respect to the structure described below.

개폐판(220)은 자중에 의해 하측으로 늘어뜨려진 상태로 천공 홀에 삽입되는데, 이러한 개폐판(220)의 하단이 천공 홀의 저면에 닿게 됨에 따른 상향구동(폐쇄구동)이 원활히 일어나도록 하기 위해서는, 개폐판(220)의 전단이 전방을 향하여 기울어진 상태로 천공 홀에 삽입되도록 하는 것이 필요하다(도 8,9).The opening and closing plate 220 is inserted into the drilling hole in the state hanged downward by its own weight, in order to allow the up and down driving (closed driving) to occur smoothly as the lower end of the opening and closing plate 220 is in contact with the bottom of the drilling hole. It is necessary to allow the front end of the opening and closing plate 220 to be inserted into the punched hole in a state inclined toward the front (Figs. 8 and 9).
