Description

Paper drain board construction method and type device more than two holes {PAPER DRAIN BOARD BUILDING METHOD AND STITCHER FOR MORE DOUBLE HOLE}

The present invention relates to a paper drainboard construction method and type apparatus, and more particularly, to a paper drainboard construction method and type apparatus for improving the soft ground.

In general, the soft ground reinforcement drain formation method is a method of improving the ground by injecting the drain board using heavy equipment on the soft layer. Such a construction requires a minimum amount of support necessary for entering heavy equipment as it is constructed using heavy equipment on soft ground. Therefore, if the relevant ground is soft ground, the required supporting power is insufficient, so that the required supporting power is secured by artificially laying soil. By the way, it is advantageous to thicken the soil laying layer only for the stability of the construction or the construction of heavy equipment, but the type becomes difficult when draining the soil layer.

The paper drain method among the soft ground reinforcement drain methods is a method of improving the ground by type paper drain boards (also called 'plastic boards') in the soft ground for drainage. This method has a hydraulic type method and a vibration type method. The vibrating type method has the advantage that the disturbance in the ground is large due to the large size of the equipment and the large cross section of the casing, while the hydraulic type method has the advantage of miniaturizing the equipment and minimizing the disturbance of the ground. There is a problem.

1 is a view showing the type equipment used in the general paper drain board construction method, Figure 2 is a view showing a cross-section of the casing used in the paper drain board type equipment of FIG.

1 and 2, the paper drainboard type equipment generally used is a heavy equipment (fork crane) 100 that can type the paper drainboard 110 is mainly used. When the paper drain board 110 is typed on the soft ground A ', the heavy equipment 100 is difficult to enter directly on the soft ground A', so that the ground fiber (B '), load distribution layer (mainly earth and sand) ) C 'and the drainage layer D' are installed, and the paper drain board 110 is inserted into the casing 130 having the cross section as shown in FIG.

In this case, the casing 130 has a large penetration resistance, so that the thicknesses of the drainage layer D 'and the soil layer C' are not uniformly laid in the field conditions, and the soil is not homogeneous. As a result, the front part of the heavy equipment is forced to be lifted or retyped by adjusting the position by force.

In such a case, if the type is excessively deformed such as partial settlement of the ground due to the partial load of the type device, it is difficult to maintain the straightness of the paper drain board due to the danger of conduction of heavy equipment and the bias of the equipment. In addition, in case of re-type, there is a problem in that it is impossible to maintain an appropriate interval and work efficiency is lowered due to a delay in type time.

On the other hand, the sand mat, a horizontal drainage layer, which is one of the main factors in soft ground treatment, is inevitably caused by the track of the type device, and the drainage layer is defined due to the fact that the floor load is laid without the upper stop work. It is less than the thickness and causes consolidation delay.

The present invention has been made to solve the above problems, and an object thereof is to provide a new type of paper drainboard construction method and type device that can solve the disadvantage of the hydraulic type method.
