Abstract

PURPOSE:To prevent loosening of a ground therearound and to increase a cut-off effect, by a method wherein an underground wall of soil cement is constructed, and newel piles, such as H-shape members, are driven at arbitrary intervals through the underground wall more deeply than the underground wall. CONSTITUTION:A soil cement wall 5 made of mixture of excavated earth and a cementing material, such as cement milk, is built to construct an underground wall 2 in a manner that the end parts are partially overlapped with each other. Thereafter, primer piles 3, such as H-shaped members, are driven in the underground wall 2 at arbitrary intervals. the newel piles 3 are driven more deeply than the underground wall 2 so that the lower ends thereof are positioned in a level lower by a necessary distance than the lower end of the underground wall 2. This permits reliable cut-off of water and prevention of settlement of a ground of the back of a landslide protection wall, and enables prevention of collapse of earth through endurance of an earth pressure and a water pressure with the aid of the newel piles.

Conventionally, in order to prevent the earth and sand from collapsing when excavating downward from the ground +I+, parent piles (3)' made of H steel are erected at appropriate intervals to the required depth, and the parent piles (3)' and the parent piles are (
It is known that horizontal piles made of wood or made of Sicly 1 are successively stacked up to the depth of the bottom of the excavation between the 3 and 3 holes. However, in this conventional example, as the excavation progresses, the horizontal sheet pile (6) is fitted between the main pile (3d and the main pile), and at that time, the back side of the horizontal sheet pile (6) is inserted. This disturbs the soil and causes a change in the surrounding ground ratio.Also, as the excavation progresses, it is necessary to insert the horizontal sheet piles (6) at the same time, which makes the work complicated. Conventionally, water leaks from the joint between the horizontal sheet pile (6) and the mountain horizontal sheet pile (6), and the water on the back side leaks, causing earth and sand to flow out onto the excavation surface along with water leakage. There was a problem in that it caused ground subsidence.

The present invention will be explained in detail below with reference to Examples. For Kienori J, first, an underground wall (2) like a soil cement wall is formed almost up to the planned bottom of the excavation. In order to form an underground wall (2) such as a soil-cement wall, for example, a circular hole is drilled using an excavator, and inside the circular hole, excavated earth and sand are mixed with a solidification material such as cement 1 to milk. A soil cement column (4) is formed by mixing and stirring the , and a column row wall is formed by forming the soil cement columns (4) one after another while partially inverting, and this column row wall is an underground wall 2) With υ, Rurui is a multi-axis excavator with multiple excavation shafts to form a rectangular hole in which multiple circular holes are connected in a string, and excavated soil and cement 1 in the rectangular hole. ~Mix with a hardening agent made of milk to form a soil cement wall (6), and form a continuous wall by forming this soil cement l-#lt5+ one after another so that the ends partially overlap. This continuous wall is used as an underground wall (2). After forming the underground wall (2) as described above, parent piles (3) such as 146f January are erected at arbitrary intervals in the underground wall (2). Here, the main pile (3) is built deeper than the underground wall (2) so that its part is located on one side of the lower end of the underground wall (2) by the necessary length. After constructing a retaining wall with parent piles as described above, the ground in the area surrounded by the retaining wall is excavated to F degree, but in this case, the surrounding area when excavating the underground wall +21 Di. The role of preventing water from leaking from the ground is thick, and for this reason, the deep part of the underground wall (2) is filled to the minimum necessary depth to stop the water at the bottom of the planned excavation. ) is sufficient, but on the other hand, the parent pile (3) should be designed so that it can prevent the earth and sand from collapsing due to earth pressure and water pressure on the back side even when the excavation reaches the planned bottom surface of the excavation. It is necessary to build it deeper by the required length.

In the present invention, as described above, an underground wall such as a soil cement wall is formed all the way up to the planned bottom of the excavation, and an arbitrary interval is left inside the underground wall to form a wall deeper than the underground wall. Since the parent pile is erected, it is possible to construct the underground wall and the parent pile at the beginning of excavation, and not only does it not require the complicated work of erecting horizontal sheet piles during excavation, but it Since there is no need to erect horizontal sheet piles during excavation, the installation of horizontal sheet piles does not disturb the soil behind the site and cause surrounding ground subsidence. Moreover, since the underground wall like a soil-cement wall is formed almost up to the bottom of the excavation where the planned collapse occurs, the underground wall like the soil-cement wall reliably stops water and prevents the ground behind the retaining wall from sinking. In addition, the main pile is built deeper into the underground wall than the underground wall, so even if you excavate to the specified ground level, the main pile will be built deeper than that.
The parent piles can withstand earth and water pressure and prevent the collapse of earth and sand.
