Description

In this paper, we propose a method of constructing underground structures consisting of vertical and horizontal slabs by using emergency steel pipe construction, and the underground structures composed of vertical and horizontal slabs constructed by this method. Method thereof}

The present invention relates to a method of rapidly constructing a straight-line hole by using a steel tube, a method of urgently and rapidly constructing an underground structure of a vertical hole and a horizontal hole by using such a method, The present invention relates to an underground structure consisting of vertical and horizontal slabs, and more particularly, it relates to an underground structure composed of vertical and horizontal slabs, in particular, in an emergency such as a disaster situation, without excessive disturbance to the ground and unnecessary excessive excavation, A plurality of vertical steel pipes are installed adjacent to the ground so as to be able to quickly supply the material (hereinafter abbreviated as "horizontally extending material") to a desired location and location on the ground, Watertight treatment by ground solidification and cutting the inside of the vertical steel pipe as necessary to communicate with each other And a method for rapidly constructing a straight hole in a state in which a hollow space is secured. Further, after forming a straight hole, the horizontal straightening material required for underground construction is horizontally By constructing horizontal slabs by piling vertical steel pipes to the ground in a state where they are lowered and placed horizontally, it is possible to quickly and quickly construct substructures consisting of vertical slabs and horizontal slabs in a disaster situation or other emergency situations. The present invention relates to an underground structure consisting of a plurality of vertical straight-horizontal straight sections.

It is often necessary to form a horizontal sphere using a steel pipe horizontally in the ground in a non-adhered manner. For example, in the case of installing a pipe in the ground across a river, a road or the like as disclosed in Korean Patent No. 10-1738370, a steel pipe is pushed from a ground at a predetermined depth in the ground by a method such as backward pressing So that the required horizontal sphere is formed. In order to form a horizontal sphere by the horizontal pivoting of the horizontal pumping steel pipe, a plurality of horizontal pumping steel pipes must be sequentially transferred from the ground to the horizontal piling installation position. To this end, It is essential to form a straight line (vertical line). In addition to the construction of a horizontal sphere, there is also a need to form a vertical sphere in order to bring a long extending material into the ground as a material necessary for various types of underground work at a predetermined depth in the earth. In the entire specification including the claims, a long extending material such as a horizontal pipe for a steel pipe, a beam member, or the like is referred to as a "horizontally extending material" as a material necessary for various types of underground work at a predetermined depth of the ground .

Conventionally, as disclosed in Korean Patent No. 10-1638478, a process of installing a panel on a vertical excavation surface while excavating a ground using a digging equipment such as auger to a predetermined depth To form a right hemisphere. In such a conventional technique, there is an advantage that a straight hole can be formed with an area sufficient for inserting a steel pipe for forming a horizontal sphere. However, an excessively long air (construction period) is required for the construction of the vertical sphere, In order to lower the material horizontally and feed it to the ground, it is necessary to form a vertical hole with a diameter larger than the length of the horizontally elongated material, so that there is a problem of "excessive perforation" in which the ground is vertically perforated with an excessively large area. In addition, in the case of the above-described conventional techniques, special measures for the panel are required in the process of forming a manual hole, and there is also a problem that fluctuation of the air (construction period) required for vertical excavation is large depending on the ground conditions.

In this specification, the direction in which the horizontal sphere is formed and extends is referred to as "longitudinal direction ", and the direction orthogonal to the longitudinal direction and the horizontal plane is referred to as" lateral direction ".

In the following description, the process for forming a golf ball of the present invention is described by exemplifying the construction of an underground structure consisting of a straight-hole and a horizontal ball. However, the object of forming a straight- For the purpose of carrying out the construction in the ground for various purposes and for supplying the horizontally extending material such as a beam, pipe or the like having a long length, such as the horizontal-use steel pipe 2, It is also possible to form a fastball. Therefore, in the following description, the term "horizontal pipe 2" is used to refer to a steel pipe for constructing a horizontal pipe in the sense of the word "vertical pipe-horizontal pipe" , The term "horizontally-bending steel pipe (2)" refers to a horizontally extending material including a long beam, pipe, or the like as a material necessary for construction in the above-mentioned manner Should be understood to be used as a meaning.

1 is a schematic flow chart of a method for constructing an underground structure according to the present invention. In FIGS. 2 and 3, a plurality of vertical steel pipes 1 are vertically FIG. 2 is a perspective view showing a process of constructing the water straight hole 10 in a stepwise manner.

In order to construct the underground structure according to the present invention, it is necessary to construct a vertical straight hole 10 having a depth equal to or greater than the depth of the ground where the horizontal hole is to be formed. In this case, a plurality of vertical steel pipes 1, A plurality of vertical steel pipes 1 are successively inserted vertically into the ground from the ground so as to be continuously arranged in contact with each other so that the interior of each vertical steel pipe 1 is excavated to form a hollow Thereby securing a space (step S1). There is no limitation on the method of installing each vertical steel pipe 1 in the ground. For example, a vertical steel pipe 1 is mounted on an oscillator and the vertical steel pipe 1 is penetrated into the ground by the weight of the oscillator, Various conventional methods such as a method of excavating the ground inside the vertical steel pipe 1 using the mounted hammer glass can be used for the underground penetration installation and the internal digging process of the vertical steel pipe 1. [ Fig. 4 is a schematic cross-sectional view along the line AA in Fig. 3 showing the state in which "the installation of a plurality of vertical steel pipes in the earth and the step of internal drilling thereof (step S1)" is completed. (Step S1) "has been completed is shown in a plan view in a schematic vertical direction.

In this manner, the structure (the "vertical steel pipe arrangement structure") in which the plurality of vertical steel pipes 1 are continuously and closely arranged to form a row, the gravel inside thereof is removed, (Hereinafter referred to as " steel pipe continuous tightly joined portion ") in which the vertical steel pipes 1 are continuously connected to each other so as to be continuous with each other, (Step S2) "by the solidification of the water. Fig. 6 is a schematic perspective view showing a state in which the both lateral sides of the steel pipe continuous tightly joined portion are solidified in the state shown in Fig. 3, and Fig. 7 shows a perspective view of the steel pipe continuous tightly- At the line BB position of FIG. 6 and Fig. 7 denote "watertight ground portion 5" formed by solidification at both lateral sides of the steel pipe continuous tightly joined portion.

As shown in the figure, the solidification treatment agent is injected into the ground at both lateral sides of the continuous pipe section to solidify the ground existing on both lateral sides of the continuous steel pipe section. As a result, 1 are communicated in the longitudinal direction to form a "communication space ", the watertightness with respect to the communication space is ensured. The watertightness treatment by solidification of the transversely opposite side ground portions of the continuous pipe portion of the steel pipe may be performed for the entire vertical length of the vertical steel pipe 1 but only to the height above the groundwater level detected through preliminary investigation of the ground It is possible.

After completion of the watertightness processing by solidification of both lateral side ground portions of the continuous pipe portion of the steel pipe, the horizontal piercing steel pipe 2 is formed so that the lower spaces of the vertical steel pipe 1 constituting the vertical steel pipe arrangement structure are communicated with each other A step of forming a communication space (step S3) by cutting off the continuous pipe portion of the steel pipe by continuous attachment of the steel pipe straight cut portion with a height and width sufficient to ensure a sufficient communication space for rotation.

8 shows a vertical steel pipe arrangement structure 10 in a state in which a lower space of the vertical steel pipe 1 is communicated with each other and a "communication space" Is shown in a schematic perspective view. 9 is a schematic plan sectional view according to line CC of FIG. 8 showing a flat cross-sectional shape at a position where the lower spaces of the vertical steel pipe 1 are communicated with each other. FIG. 10 shows a vertical steel pipe 1, Sectional view corresponding to Fig. 9 in which the vertical wall portion cut off from the vertical steel pipe 1 is shown by a red dotted line so that the lower spaces of the vertical steel pipe 1 are communicated with each other. Fig. 11 is a schematic cross-sectional view taken along the line D-D in Fig. 8.

8 to 11, after the watertight processing step (step S2) by solidification of the transversely opposite side ground of the continuous pipe section of the steel pipe is completed, in step S3, the vertical steel pipe 1 is brought into close contact with the steel pipe Is cut and cut to a predetermined height and a predetermined width, so that the inside of the vertical steel pipe arrangement structure 10 is in a state of being communicated with each other, Space "is formed. In Fig. 10, a portion indicated by a dotted line in red is cut and removed from the continuous wall of the continuous steel pipe 1. In Fig.

In order to achieve the inner communication of the vertical steel pipe arrangement structure 10, the cut-off height of the continuous steel pipe 1 with respect to the vertical wall is set to be equal to or less than the formed height of the watertight ground portion 5 , And a height calculated in advance so as to secure a sufficient space for rotating the horizontal-use steel pipe 2 as described later. The width of the continuous steel pipe 1 in the transverse direction with respect to the vertical wall is set such that it does not deviate from the watertight ground portion 5 on both lateral sides, that is, the width of the watertight ground portion 5 or less.

By thus cutting the continuous wall at the position of the continuous pipe of the steel pipe in which the continuous steel pipe 1 is in close contact with each other in the range of the height and the width without departing from the watertight ground portion 5, The inner surface of the vertical steel pipe arrangement structure 10 is communicated with each other while securing a sufficient space for rotating the horizontal steel pipe 2 for horizontal rotation. After the execution of the "communication space forming step (step S3) by cutting off the vertical pipe by continuous pipe-cutting of the steel pipe" or, in parallel thereto, with respect to the vertical pipe at the outermost position in the longitudinal direction in which the horizontal pipe is to be formed, A steel pipe passage hole 6 through which the horizontal pipe 2 is to pass is formed through the vertical wall of the vertical steel pipe in the direction in which the sphere is to be formed.

By constructing the vertical steel pipe arrangement structure 10 by performing steps S1 to S3 described above, the construction of the vertical sphere is completed as the previous step for forming the horizontal sphere. After the construction of the vertical sphere is completed as described above, the horizontal pumping steel pipe 2 is inserted into the ground through the vertical hole. As mentioned above, the purpose of forming a water hole is various, so the term "horizontal pipe for reclamation (2)" depends on the purpose of construction of the vertical hole, . &Lt; / RTI > However, in the case of constructing an underground structure composed of a right-hand and a left-hand elevation using the above-described present invention, after forming the right-hand straight as described above, a plurality of horizontal- And the horizontally-pushing steel pipe 2 is horizontally pivoted to the ground using a rear-side pressurizing device, thereby constructing a horizontal hole.

According to the present invention, the formation of the above-mentioned cross member can be used to feed various kinds of horizontally extending materials into the ground. That is, in the method of supplying the horizontal extending material according to the present invention, after forming the vertical pipe according to the above-mentioned method steps, the horizontal extending material is vertically erected or tilted to form one vertical steel pipe 1 And the horizontal extending material is horizontally arranged by rotating the horizontal extending material in the communication space inside the vertical steel pipe arrangement structure 10.

In the following, a method for constructing an underground structure composed of a straight-hole and a horizontal straight line according to the present invention will be described in detail. The steel pipe 2 for horizontal pumping is lifted by lifting equipment such as a crane and is sent down to the ground through the vertical steel pipe 1 existing at the middle position of the vertical steel pipe arrangement structure 10. At this time, in the present invention, the horizontally-bending steel pipe 2 is not horizontally lowered but vertically lowered vertically or inclined so as to pass through the diameter of the vertical steel pipe 1 The vertical descending step of the steel pipe) (step S4). Fig. 12 is a schematic cross-sectional view subsequent to Fig. 11 showing a vertically lowered vertical-bending steel pipe 2 vertically lowered into a vertical steel pipe 1 as described above, and Fig. 13 shows a horizontal bending steel pipe Sectional view corresponding to Fig. 12 showing that the pipe 2 is tilted so as to pass through the diameter of the vertical steel pipe 1 and vertically lowered into the inside of the vertical steel pipe 1. In Fig.

As shown in FIG. 12, the horizontal pipe 2 for a horizontal bending is vertically erected or the horizontal pipe 2 for a horizontal bending is inclined as shown in FIG. 13 to be lowered into one vertical pipe 1, After being carried into the structure 10, in the communication space inside the vertical steel pipe arrangement structure 10 secured by the above-described step S3, the horizontal placement step by rotation of the horizontal pipe 2 ). Figs. 14 to 17 are schematic cross-sectional views corresponding to Fig. 13 sequentially showing respective processes of horizontally arranging the horizontally-bending steel pipe 2 in the communication space inside the vertical steel pipe arrangement structure 10 And FIG. 18 is a schematic cross-sectional view corresponding to FIG. 13 showing all the positions of the horizontal-bending steel pipe 2 shown in FIGS. 14 to 17. In Fig. 7, P1 to P5 indicate positions of the vertically-bending steel pipe 2 which are sequentially changed.

As shown in FIGS. 14 to 18, the horizontally-bending steel pipe 2 carried into the vertical steel pipe arrangement structure 10 is rotated in a suspended state to be in a horizontal position. As described above, Since a sufficient communication space is secured inside the vertical steel pipe arrangement structure 10 through the communication step (step S3) by cutting off the continuous pipe of the vertical steel pipe by continuous cutting of the vertical steel pipe, The horizontally tilting steel pipe 2 brought into the tilted state can be easily positioned in the horizontal state by rotating in the communication space.

For the construction of underground structures consisting of a vertical hole and a horizontal hole, the horizontal pipe for horizontal formation (2) for the formation of horizontal holes should be placed horizontally in the ground. However, according to the prior art in which a vertical hole is formed by excavating a ground using a digging equipment such as auger to construct a vertical hole, the work is progressed in such a manner that the horizontal pipe 2 is horizontally lowered to the ground, It is necessary to form a very wide straight pipe so as to have an area corresponding to the length of the horizontal pipe 2 for forwarding and thus an excessively long air is required for the construction of the vertical pipe, There was a disadvantage of "excessive piercing" which caused the ground to be pierced by the area.

However, according to the present invention, after the horizontal pipe 2 for horizontal bending is vertically erected or inclined only to the extent that it is inserted into the diameter of one vertical steel pipe 1, It is possible to minimize the area for vertical excavation of the ground for the introduction of the horizontal boring steel pipe 2 into the ground. Therefore, it is possible to prevent excessive piercing of the vertical sphere, which is a problem of the prior art, and thus, a very advantageous effect such as cost reduction and shortening of the air required for the construction of the vertical sphere can be exerted.

After the horizontally-bending steel pipe 2 is disposed horizontally at a designed position in the ground by performing the horizontally placing step (Step S5) of the horizontal-bending steel pipe 2 by rotation, the horizontal bending steel pipe 2 is put into the vertical steel pipe 1 The horizontal pushing steel pipe 2 is pushed out and pushed horizontally on the ground by using the rear pressurizing device 9 that has been provided (step S6). 19 is a schematic cross-sectional view corresponding to Fig. 18 showing a state in which the horizontal-use steel pipe 2 is pushed horizontally on the ground.

When the extended length of the horizontal pipe 2 is shorter than the designed length of the horizontal pipe, a plurality of horizontal pipes 2 are brought into the above-described process, that is, The steel pipe is vertically or vertically inclined only to the extent that it is inserted into the diameter of one vertical steel pipe 1 and then put in the ground and rotated horizontally in a communication space previously formed in the vertical steel pipe arrangement structure 10 "Are successively repeated to continuously horizontally pivot on the ground to construct a horizontal sphere.

Unlike the prior art in which the circular water hole is to be excavated so as to have a diameter equal to or larger than the extension length of the horizontal pipe 2, as described above, in the present invention, the pipe 2 for horizontal pumping is vertically erected, Since the steel pipe is inclined only to be inserted into the diameter of the vertical steel pipe 1 and then is inserted into the ground, the steel pipe can be installed at a much higher speed than in the prior art and the area required for forming the steel pipe is greatly reduced. Advantages of such "improvement of the construction speed" and "reduction of the area required for the formation of a number of holes" For example, when a disaster such as a collapse of a building occurs, it is necessary to rapidly form a horizontal sphere in an adjacent area in order to approach the point where a disaster occurs. Firstly, in the present invention, Technology, it is possible to secure a point where a water droplet can be easily formed even in the presence of existing buildings near a disaster occurrence point. In addition, since it is possible to construct a water jetting jet at a speed much faster than that of the prior art, it is possible to greatly reduce the time required to form a horizontal jet to the point of occurrence of the disaster after the formation of the jet stream, The advantage of being able to perform is demonstrated. Further, since the present invention can be very usefully used for urgent construction of the urban area, it is possible to shorten the air through the rapid construction of the above-mentioned water straight hole and the horizontal straight road, So that the social cost can be minimized.

As described above, according to the present invention, it is possible to construct an underground structure composed of a straight-hole and a horizontal straight line in an urgent situation, quickly and safely in a state in which disturbance on the ground is minimized. In the present invention, since a plurality of vertical steel pipes are used in the construction of a straight pipe, it is possible to secure stability during vertical excavation work, ensure perfect water quality, .
