Description

Apparatus for Continuous Construction Walls of Underground Structure}

The present invention relates to a continuous construction apparatus of the wall of the underground structure, and more particularly to the excavation work of the ground along the location where the wall of the underground structure is to be constructed while injecting cement milk and stirring the soil and cement milk. The present invention relates to a continuous construction apparatus for a wall of an underground structure that can shorten the wall construction period and reduce the construction cost by performing continuously.

In general, in order to build underground structures, after installing temporary facilities at the construction site, excavate the soil and prepare a predetermined space, install a wall to prevent the earth and sand collapse by using a number of H-beams and earth plate, and then assemble formwork and concrete The so-called temporary mud-proofing method of constructing the basement walls by pouring them into the mainstream.

However, when the underground structure is constructed by the temporary construction method as described above, when the underground excavation work is difficult due to excessive groundwater inflow, construct the earth and earth collapse prevention structure using H-beam and order grouting earth plate, and then excavate the excavation work. And there is a difficulty in constructing the underground structure, accordingly there is a problem that the number of processes for the construction increases, the construction period is extended.

In addition, there is a possibility of long-term stratum deformation due to the impossibility of perfect refilling of the drawing space of the H-beam and installation of the earth plate and the dismantling of the earth plate. .

In order to solve this problem, as shown in FIG. 1, the present inventor discloses a wall construction method of the underground structure in Korean Patent Publication No. 10-0781810. The wall construction method of the disclosed underground structure includes the steps of: installing a column 10 at a wall end point of the underground structure; Indenting the panel unit (20) having a U-shape between the pillars (10) in sequence; Removing soil in the panel unit (20); Reinforcing reinforcing bars in the panel unit (20); And removing the panel unit 20 after the concrete is poured into the panel unit 20 before the concrete is completely dried. In FIG. 1, reference numeral 27 denotes a guide rail 27 for ensuring verticality when the panel unit 20 is press-fitted between two pillars 10.

However, such a method has a disadvantage in that the material cost is high and the construction period is extended by constructing a large number of panels having a complicated shape and then using the same.

On the other hand, when the wall of the underground structure is to be installed high, the excavation work of the ground is not easy, and after the entire space where the wall is to be installed is laid, a large number of formwork is installed until the mold is laid and cured. The drawing work is accompanied, and the excavation work of the ground and the concrete placing work are separated separately, which causes a lot of manpower, material cost and construction period.

In addition, when the wall of the underground structure should be constructed in a shape that encloses the rectangular space, one side of the wall is excavated the ground at the location where the construction is to be made, and then the direction is changed at right angles at the end of the excavated space to be adjacent to the construction of the wall Since the ground of the location must be excavated, the operation of precisely moving the excavation device to the excavation position is not easy and consumes a lot of time.
