Description

고결토의 제조방법 및 그 방법에 의한 고결토{A MOTHOD OF PREPARATION FOR A COAGULATING SOIL AND A COAGULATING SOIL THEREBY}Manufacturing method of coarse clay, and coarse clay by the method {A MOTHOD OF PREPARATION FOR A COAGULATING SOIL AND A COAGULATING SOIL THEREBY}

본 발명은 연약지반을 개량하거나 토목이나 건축시공 현장에서의 하수, 상수, 가스관 등 관의 매설공사에 있어서 외부로부터의 압력이나 충격 등으로 인하여 발생가능한 관의 손상등에 대한 매설관의 보호층 조성시 사용하기 위한 고결토의 제조방법 및 그 방법에 의한 고결토에 관한 것이다.The present invention is to create a protective layer of buried pipe against damage or damage to the pipe that may be caused by pressure or impact from the outside in the construction of pipes such as sewage, water, gas pipes, etc. in civil engineering or building construction site The present invention relates to a method for producing coarse clay for use, and to coarse clay by the method.

종래 지반이 연약한 해안습지나 하천, 호수 등에서의 공사시 그 지반으로 사람이나 장비등이 진입할 수 있도록 표면층을 고화처리하거나 기초지반을 보강하기 위하여 심층을 고화처리하기도 하며 나아가 말뚝박기 등의 공사를 통해 지반을 견고하게 만들기도 한다.In case of construction in coastal wetlands, rivers, lakes, etc. where the ground is soft, the surface layer may be solidified or the pile may be solidified to reinforce the foundation so that people or equipment may enter the ground. It also makes the ground firm.

이와같이 연약지반을 고화처리하기 위해서 종래에는 보편적으로 일반시멘트를 이용한 1960년대에 개발되어 사용되어온 시멘트계슬러리를 이용한 고화처리공법 등을 사용하여 왔으며 어느정도 효과를 가지고 있으나 입자가 미세하고 특히 함수비가 50% 이상의 고함수 점성토의 고화에 있어서는 목적한 바를 얻을 수 없는 문제점이 있었다.As such, in order to solidify the soft ground, conventionally, the solidification treatment method using cement slurry, which has been developed and used in the 1960s using general cement, has been used. Although it has some effects, the particles are fine and the water content is particularly 50% or more. In the solidification of high-function cohesive soils, there was a problem that the intended purpose was not obtained.

이를 해소키 위하여 시멘트에 각종의 첨가제를 배합하여 고화제로 이용하는 방법들이 많이 있으나 일종의 노하우로 완전히 공개되고 있지 않은 실정이다.In order to solve this problem, there are many methods of adding various additives to cement to use as a hardener, but they are not completely disclosed as a kind of know-how.

이에 대한민국 특허등록번호 제0145637호의 연약지반 개량용 고화제는 연약지반 처리대상 연약토 1톤당 시멘트 50-200kg과 시멘트 중량대비 10-20%의 플라이애쉬(fly-ash)와 1-3%의 리그닌 슬폰이트를 혼합하여 분말상 고화제를 제조하여 연약지반 개량용 고화제로 사용하고 있으며 대단위 공사등에는 적합하나 소규모의 공사에는 재료의 공급이나 비용적인 측면에서 문제점을 내포하고 있는 실정이다.Accordingly, the solidifying agent for soft ground improvement of Korean Patent Registration No. 0145637 includes 50-200kg of cement per 10 tons of soft soil to be treated with soft ground, 10-20% fly-ash and 1-3% of lignin Powdered hardener is prepared by mixing sulfonate and used as a hardener for soft ground improvement. It is suitable for large-scale construction, but there are problems in supplying material and cost in small-scale construction.

이와는 별도로 당업자에게 잘 알려진 바와 같이 종래에는 하수관, 상수관, 가스관 등 각종 목적의 관을 매설코자 함에 있어서 터파기 공사를 하고 향후 발생가능한 외부로부터의 압력시 파손될 수 있는 관의 보호를 위하여 관을 매설할 지점에의 각종 암반과 돌 등 크고 잡다한 물질을 제거한 후 관을 설치 연결하고, 터파기 하면서 발생한 원토로 되메우기를 하여 관 포설을 완성하여 왔으며, 상기 상수관과 가스관 등은 향후 발생가능한 외압으로부터 관을 보호하기 위하여 매설될 관로의 하단지점에 양질의 모래 또는 원토를 공사 시방에 맞도록 경사를 주어 지반 정리를 한 후 상기 관을 연결설치한 후에도 다시 그 주위에 양질의 모래 또는 원토를 부설하므로서 관 포설공사를 시행하였는데 실제 시공현장에서 일반적으로 크기가 40m/m 이상의 돌멩이, 75m/m 이상의 진흙덩어리, 나무뿌리, 쓰레기 및 응결토 등 이물질이 제거된 흙인 양질의 모래 또는 원토 사용은 이러한 이물질 제거를 위한 부수적인 공정이 수반되어야 하는 문제점이 있다.Apart from this, as is well known to those skilled in the art, in order to bury pipes for various purposes such as sewer pipes, water pipes, gas pipes, and the like, the pipes are buried to protect pipes that may be damaged in case of possible external pressure. After removing large and miscellaneous materials such as rocks and stones at the point to be installed, the pipes are installed and connected, and the pipes are filled by filling back the raw soil generated during the burrow, and the water pipes and the gas pipes are separated from the external pressure that may occur in the future. In order to protect the pipes, the slopes of high-quality sand or raw soil are inclined to fit the construction specifications at the lower point of the pipeline to be buried, and after the pipes are connected, the high-quality sand or raw soil is laid again. Laying work was carried out at actual construction sites. The use of high quality sand or raw soil, such as mud lumps of more than 5 m / m, tree roots, garbage and condensed soil, has been a problem that must be accompanied by an additional process for removing such foreign matter.

또한 터파기한 흙을 되메우기에 사용하는 통상적인 방법은 원지반토의 성상 및 토질, 역학적인 성상을 전혀 고려하지 않고 있으며 또한 터파기 후 지반에서 지하수가 발생시에도 지하수만을 배제한 후 관을 연결 및 포설하므로 상당한 기간이 경과한 후에는 관이 매설된 지점에 다시 지하수가 유입되어 지반이 침하되고 심할 경우에는 이때문에 도로까지 붕괴되는 현상이 자주 발생하는 것을 알 수 있으며, 이러한 지하수의 유입을 막기 위한 수단으로 관 상부에 콘크리트 옹벽을 설치하거나 관의 하부에 기초 말뚝공사 등 지반정리를 하는 바 이와 관련하여 과다한 공사비가 투입되어지는 폐단이 발생하였다.In addition, the conventional method used for backfilling the excavated soil does not take into account the characteristics of soil, soil, and mechanical properties. Also, when groundwater occurs in the ground after excavation, only groundwater is excluded, and pipes are connected and laid for a considerable period of time. After this time, the groundwater flows back to the point where the pipe is buried, and the ground subsides, and if it is severe, it is often collapsed to the road.This means that the groundwater is prevented. The concrete retaining wall was installed in the upper part, or the ground was cleaned up such as foundation pile work in the lower part of the pipe.

특히, 관로는 지하에 매설되고 부지조성등의 부속사업으로 설치되는 특성등으로 인하여 대부분 시행관청의 관심이 소홀하여 부실하게 공사될 우려가 있고, 일단 부실하게 공사된 관로의 개량에는 도로 굴착 및 복구에 따른 과다한 비용이 소요되며, 이러한 보수공사로 인하여 교통체증을 유발하여 국민의 생활불편에 따른 민원이 야기되는 등 많은 문제점을 가지고 있다.In particular, due to the characteristics of underground pipes installed as subsidiary projects such as site construction, most of them may be neglected and poorly constructed. Excessive costs are required, and such repair works cause traffic jams, causing civil complaints due to the inconvenience of the people.

본 발명은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 주 목적은 연약지반을 개량시키고 또한 관로의 매설시 본발명에 의한 고결토를 투입시킴으로서 외부요인으로 인한 지하에 매설된 관로의 파손 및 함몰을 방지할 수 있는 고결토의 제조방법 및 그 방법에 의한 고결토를 제공하려는데 있다.The present invention was created in order to solve the problems of the prior art as described above, the main object of the present invention is to improve the soft ground and also to inject the coarse clay according to the present invention when the pipeline is buried underground due to external factors An object of the present invention is to provide a method of manufacturing cohesive clay which can prevent breakage and depression of embedded pipelines, and coarse clay according to the method.

본 발명의 또다른 목적은 매설관의 파손 및 함몰로 인해 하수의 유출을 미연에 방지하여 지하수의 오염을 방지하여 생성에도 도움을 주며, 항구적으로 자연 환경을 보호하려는데 있다.Another object of the present invention is to prevent the leakage of sewage due to breakage and depression of buried pipe in advance to help the generation of pollution of groundwater, and also to protect the natural environment permanently.

Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

본 발명의 고결토 제조방법은 공사현장에서 터파기 등으로 인하여 발생된 현장발생토에 시멘트와 생석회 그리고 폐타이어 박편을 현장여건에 따라 적절히 조정하면서 혼합기를 이용하여 혼합한 후 파라핀을 이용하여 제조한 고화제를 살포하므로서 고결토를 제조하게된다.In the method of manufacturing high-clay soil according to the present invention, the cement, quicklime and waste tire flakes are mixed by using a mixer while appropriately adjusting cement and quicklime flakes according to the site conditions, which are generated due to rupture at the construction site, and then manufactured using paraffin. By spraying the hardening agent to produce a high-kilometer.

이를 첨부된 도 1을 참조로 보다 상세히 설명하면,Referring to this in more detail with reference to Figure 1,

터파기 공사후 발생한 현장발생토(1)에 일반시멘트(3) 2∼7%를 첨가한 후 상기물을 제1 혼합기(5)를 이용하여 충분히 혼합시킨 후 혼합된 조성물(6)을 제2 혼합기(9)에 투입한 후 대한민국 특허등록번호 제0211348호의 고형화를 촉진시킴과 동시에 방수효과를 얻을 수 있는 수용성 파라핀을 이용한 고화제(7)를 기계분무기 (8)를 이용하여 골고루 살포하면서 상기 조성물(6)과 균일하게 잘 섞이도록 교반 혼합 및 살포를 행하여 고결토(10)를 제조한다.After adding 2 to 7% of the general cement (3) to the on-site soil (1) generated after the excavation work, the water was sufficiently mixed using the first mixer (5), and then the mixed composition (6) was added to the second. The composition was sprayed evenly using a mechanical sprayer (8) with a solidifying agent (7) using a water-soluble paraffin that promotes the solidification of the Republic of Korea Patent Registration No. 0211348 after obtaining into the mixer (9) and at the same time to achieve a waterproofing effect Stirring mixing and sparging are carried out so as to mix uniformly with (6), thereby producing coarse clay (10).

상기에서 제1, 제2 혼합기는 통상적인 수동식이나 기계식, 유압식 또는 전기식 등의 믹서나 혼합기등이 사용될 수 있으며 또한 고정식이나 이동식의 혼합기가 사용되어질 수 있다.In the above, the first and second mixers may be conventional mixers or mixers, such as manual, mechanical, hydraulic or electric, and also fixed or mobile mixers may be used.

상기에서 지반조성지의 부드러운 작용과 각종 관의 충경을 예방할 경우에 현장발생토에 시멘트 2 ∼ 7%를 첨가하기전에 폐타이어를 잘게 부순 덩어리(2)를 10 ∼ 50% 첨가하여 혼합하고, 불량지반이나 연약지반일 경우에는 현장발생토에 시멘트 2 ∼ 7%와 함께 생석회를 2 ∼ 5%를 첨가하여 혼합하며, 흙의 입자를 안정케 하여 고화제를 살포하여 전압 다짐후 지반치환층을 형성할 수 있게 된다.In order to prevent the soft action of the soil composition and the filling of various pipes, 10 to 50% of the crushed lumps (2) of finely divided waste tires are added and mixed before the addition of 2 to 7% of cement to the field-produced soil. In the case of soft ground, 2 to 7% of cement and 2 to 5% of quicklime are added to the soil, and the soil particles are stabilized by spraying a hardener to form a ground replacement layer after the compaction. It becomes possible.

상기와 같은 방법으로 제조된 고결토를 첨부된 도2에 보여진 것처럼 매설관 공사를 할 원지반토의 성상에 따라 매설되는 배관(400)에 대하여 10 ∼ 30cm 포설하고 각종 관 매설공사 시공지침 및 흙의 다짐율에 따라서 다짐을 주면 다음의 표1의 현장발생토 일실험예에서 볼 수 있는 것처럼 관보호층의 일축강도가 5 ∼15㎏/㎠ 이상 발휘하여 매설된 관로가 수압 및 토압에도 지장이 없으며, 차량의 하중에도 충분한 지지력을 발휘하고, 또한 불투수력이 생겨 관로의 파손 및 함몰로 인해 하수가 누수되는 율인 투수계수 10-5cm/초 이하 ∼ 불투수까지 형성되어 만일 누출되는 하수가 발생한다 하여도 기초 지반보호층의 두께에 따라 통과된 하수는 흙의 자정능력을 통해 하수가 아닌 무공해한 지하수로 변해서 누수되는 것을 알 수 있다.As shown in Fig. 2 attached to the coarse clay prepared in the above method, 10 ~ 30cm laid for the pipe 400 buried according to the properties of the raw alumina to be buried pipe construction and various construction guidelines for pipe laying work and compaction of soil According to the ratio, as shown in the field test soil example in Table 1 below, the uniaxial strength of the pipe protective layer exhibits 5 to 15㎏ / ㎠ or more, so that the embedded pipeline is not affected by water pressure and earth pressure. Sufficient bearing capacity is applied to the load of the vehicle, and impermeable power is generated, and a permeability coefficient of 10 -5 cm / sec or less to impermeable water, which is the rate at which the sewage leaks due to breakage and crushing of the pipe, is generated. Also, it can be seen that the sewage passed according to the thickness of the foundation ground protection layer is turned into pollution-free groundwater rather than sewage through the soil's self-cleaning ability.

첨부된 도2에서 미설명된 부호는 관을 매설하기 위하여 터파기하는 골(100), 불량지반시 고결토를 이용하여 치환시키는 불량지반치환층(200), 관을 보호하는 관보호층(300), 매설되는 배관을 보호하는 고결토충진층(500), 현장발생토로 충진하는 현장발생토충진층(600) 그리고 포장재 또는 도로(700)를 나타낸다.In the accompanying FIG. 2, the reference numerals not shown refer to the trench 100 to bury the tube, the poor ground replacement layer 200 to be replaced by the high soil during poor ground, and the tube protective layer 300 to protect the tube. ), A high-density soil-filling layer 500 to protect the buried pipe, a site-borne soil-filling layer 600 filled with field-produced soil and pavement or road 700.

상기에서 알 수 있는 것처럼 특히 연약지반 지역에 관로공사를 시행할 경우에는 기초 말뚝공사등을 시공함으로 막대한 공사비를 투여하는 결과를 초래하였으나 본 방법으로 조성된 고결토를 30 ∼ 50cm 정도 기초지반층으로 시공하면 연약지반 개량의 효과가 나타나는 것을 확인 할 수 있다.As can be seen from the above, especially in the case of the pipeline construction in the soft ground area, the construction of foundation piles, etc. resulted in the enormous cost of the construction, but the coarse clay formed by this method was formed into the foundation soil layer by 30 ~ 50cm. It can be seen that the effect of soft ground improvement is achieved by the construction.

본 발명은 다양하게 변형될 수 있고 여러 가지 형태를 취할 수 있으며 상기 발명의 상세한 설명에서는 그에 따른 특별한 실시예에 대해서만 기술하였다. 하지만 본 발명은 상세한 설명에서 언급되는 특별한 형태로 한정되는 것이 아닌 것으로 이해되어야 하며, 오히려 첨부된 청구범위에 의해 정의되는 본 발명의 정신과 범위 내에 있는 모든 변형물과 균등물 및 대체물을 포함하는 것으로 이해되어야 한다.The present invention can be variously modified and can take various forms and only the specific embodiments thereof are described in the detailed description of the invention. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
