본 발명은 내조용 사석제방의 내만 쪽에 토사제방을 축성할 때 사석제방의 돌틈으로 드나드는 조수의 방해에도 불구하고 안전하게 방조제, 하구둑 등의 필터 시공방법에 관한 것이다.The present invention relates to a method for constructing a filter such as a seawall, a river bank, etc. safely in spite of the tidal wave entering and exiting the rock of the sandstone embankment when the earthquake embankment is built on the inner bay side of the internal sandstone embankment.

사석제방의 내만 쪽에 성토작업으로 토사제방을 구축하던 종래의 방조제 시공방법은, 도 1에서 보듯이, 사석 제방(1)의 내만쪽에 상당한 두께로 자갈-모래(2)를 포설하여 돌틈을 줄이고, 자갈-모래(2) 위에 토목섬유제 필터 매트(3)를 포설한 다음에 토사를 성토하여 토사제방(4)을 조성하는 순으로 진행해 왔다.In the conventional method of constructing the earth and sand embankment by filling work on the inner bay side of the sandstone embankment, as shown in FIG. 1, gravel-sand (2) is laid at a considerable thickness on the inner side of the sandstone embankment 1 to reduce the stone gap, Geotextile filter mats (3) were installed on the gravel-sand (2), and then the earth and sand were deposited in order to form the soil mounds (4).

투수성인 필터 매트로 해수의 간조 및 만조 시에 해수가 통과하기 마련인 데, 이럴 때마다 쌓아 둔 필터용 자갈과 모래가 내만쪽으로 유실되고, 필터 매트의 자세가 흐트러져 토사제방의 성토공정진행상 차질을 빚기도 한다. The permeable filter mat is designed to allow seawater to pass through at low and high tide. Whenever this happens, the accumulated filter gravel and sand are lost to the inner bay. I also owe it.

또, 자갈-모래층이 두텁게 설계되므로 방조제 시공원가가 높고, 자갈과 모래 및 토사의 유실로 인하여 공기가 지연되고, 그런 만큼 공정은 까다로와져서 공사비의 지출이 늘어나는 요인으로 작용한다. In addition, because the gravel-sand layer is designed thickly, the city park price is high, and the air is delayed due to the loss of gravel, sand, and soil, and thus, the process is complicated, thus increasing the cost of construction.

따라서 본 발명의 목적은 조수의 간만으로 인한 시공 중 필터용 자갈-모래의 유실 억제와 필터의 자세 유지, 공기 단축, 공사비 절감에 유효한 방조제 등의 필터 시공방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a filter construction method such as a seawall which is effective in suppressing the loss of the gravel-sand for the filter during construction due to tidal tides, maintaining the posture of the filter, shortening the air, and reducing the construction cost.

이 과제는, 튜브가 일방향으로 연속되게 형성된 투수성 토목섬유제 팩 필터를 튜브가 종방향으로 놓이게 사석 제방의 내만쪽에 설치하고, 팩 필터의 모든 튜 브에 자갈-모래를 충전하며, 팩 필터 겉에 계획된 높이와 폭으로 토사를 성토하여 토사제방을 구축해 방조제를 완성하는 방법으로 달성할 수 있다.The task is to install a permeable geotextile pack filter in which the tubes are arranged in one direction, on the inner side of the sandstone embankment with the tubes in the longitudinal direction, filling all the tubes of the pack filter with gravel-sand, It can be achieved by laying up the soil at the planned height and width to build a soil dike and complete the dike.

도 2에서, 본 발명에서 제안하는 팩 필터(10)는 투수성을 가진 토목섬유를 소재로 하여 일방향으로 튜브(11)가 배열되도록 제작한 필터 매트 대용물이다. 튜브(11)의 상단(12)은 틔워서 자갈-모래를 충전할 수 있게 한다. 하단(13)은 막아서 상단(12)으로 채워지는 자갈-모래의 밑빠짐을 방지할 수도 있고, 상단처럼 열린 상태로 방치할 수도 있다. 튜브(11)가 내만쪽 하상에 매입되는 경우에는 밑을 굳이 봉하지 않아도 채워진 자갈-모래가 빠져나가지 못하기 때문이다. In FIG. 2, the pack filter 10 proposed in the present invention is a filter mat substitute manufactured by arranging the tubes 11 in one direction using geotextile fibers having water permeability. The top 12 of the tube 11 is steamed to make it possible to fill the gravel-sand. The lower end 13 may be prevented from falling out of the gravel-sand filled with the upper end 12, or may be left open as the upper end. If the tube 11 is buried under the inner bay, the filled gravel-sand does not escape even if the bottom is not sealed.

도 3에서, 미리 축조된 사석 제방(1)의 내만쪽에 팩 필터(10)를 설치한다. 이때, 튜브(11)는 상단(12)이 정상에 위치하도록 일렬횡대로 배치한다.In FIG. 3, the pack filter 10 is provided only in the inner side of the preliminary-built sandstone dike 1. At this time, the tube 11 is arranged side by side so that the upper end 12 is located at the top.

튜브(11)마다 자갈-모래(2)를 채운다. 상단(12)은 열린 채로 방치해도 무방하다. 자갈-모래(2)는 튜브(11)에 의해 안전하다. 그래서 사석 제방(1)의 돌틈으로 해수가 드나들더라도 자갈-모래(2)는 팩 필터(10)에 보호되므로 유실되지 않는다. 자갈-모래(2)가 유실되지 않으니 팩 필터(10)의 자세도 조금도 흐트러지지 않을 정도로 안정된다. Each tube 11 is filled with gravel-sand (2). The upper end 12 may be left open. The gravel-sand 2 is secured by the tube 11. So, even though seawater enters the stone gap of the sandstone embankment 1, the gravel-sand 2 is not lost because it is protected by the pack filter 10. Since the gravel-sand 2 is not lost, the posture of the pack filter 10 is also stabilized so as not to be disturbed at all.

이처럼 자갈-모래(2)의 유실과 팩 필터(10)의 자세가 안정되면 자갈-모래의 보충과 흐트러진 필터 매트의 자세 바로잡기, 토사의 보충작업 등 불필요한 작업이 사라져 공기가 지연되는 일이 없고 오히려 공기는 단축되고 자갈과 모래 및 토사의 소요량도 경감되어 방조제 축조비가 절약된다. When the loss of the gravel-sand 2 and the posture of the pack filter 10 are stabilized, unnecessary work such as replenishment of the gravel-sand, correcting the posture of the dished-out filter mat, replenishment of earth and sand are eliminated, and the air is not delayed. Rather, the air is shortened, and the requirements for gravel, sand and soil are also reduced, which saves the cost of constructing the dike.

도 4는 사석 제방(1)에 직접 시공되는 제1 팩 필터(10)는 자갈(2a)을 채우고 제2 팩 필터(10a)는 모래(2b)를 채워서 팩 필터의 자갈,모래 및 토사층 보호기능을 강화한 2중 팩 필터형으로 방조제(1)를 축성하는 경우를 예시한 것이다.4 shows that the first pack filter 10 directly installed on the sandstone embankment 1 fills the gravel 2a and the second pack filter 10a fills the sand 2b to protect the gravel, sand and soil layers of the pack filter. It is an example of the case of building the auxiliary agent (1) in a double-pack filter type reinforced with.

팩 필터(10,10a)를 복층으로 시공하면 자갈층과 모래층에 의한 필터층의 두께가 2배로 늘어나고, 제1 팩 필터(10)에 의한 제2 팩 필터(10a)의 모래층에 대한 보호기능과 거기에 성토되는 성토층에 대한 제2 팩 필터(10a)의 보호기능이 더욱 강화돼 보다 안전하게 성토에 의한 토사 제방(4)을 축조할 수 있다.When the pack filters 10 and 10a are formed in multiple layers, the thickness of the filter layer by the gravel layer and the sand layer is doubled, and the protection function against the sand layer of the second pack filter 10a by the first pack filter 10 and The protection function of the second pack filter 10a against the fill layer that has been deposited is further strengthened, so that the earth and sand banks 4 due to the fill can be safely constructed.

이상 설명한 본 발명의 팩 필터를 이용한 방조제 시공방법은 종래의 필터 매트를 이용한 방조제 시공방법보다도 조수의 간만으로 인한 자갈-모래-토사의 유실이 억제되고 이에 따라 필터의 자세도 시종 일관 유지되므로 As described above, the method of constructing the seawall using the pack filter of the present invention is more effective in suppressing the loss of gravel-sand-soil caused by tidal current than in the conventional seawall construction method using the filter mat, and thus the posture of the filter is consistently maintained.

방조제의 공기 단축이 가능하고, 이와 함께 조수에 유실되는 자재도 미미해 공사비 절감효과가 크다.It is possible to shorten the air of the scavenger, and at the same time, the material lost in the tides is insignificant, thus greatly reducing the construction cost.
