Abstract

PURPOSE:To permit the omitting of processes and also diversional use of stay steel sheet piles by a method in which stay steel sheet piles are erected at given intervals to the back side of the active degradation angle on one side of a sheathing steel sheet pile and then excavation is made. CONSTITUTION:A sheathing steel sheet pile 3 is erected into the ground 1 and stay steel sheet piles 4 are driven at given intervals to the back side (A-B line) of the active degradation angle on one side of the sheet pile 3. Reaction of earth pressure and water pressure to the sheet pile 3 is transmitted to the stay steel sheet piles 4 to offer a resistance originated in the friction forces on the back side, and thereby the deformation of the sheet pile 3 and also of the ground's surface is reduced. Excavation is then made to a given position of the ground 1 facing the sheet pile 3. In this case, a waling 2 is set in place.

。Detailed Description of the Invention This invention provides a steel sheet pile in which, prior to root cutting in earth retaining work, one steel sheet pile is erected at a predetermined interval on one side of the earth retaining steel sheet pile, and then root cutting is performed while leaving the earth retaining steel sheet pile. Regarding earth retaining method.

加したり地表面の変形が大きくなる欠点があった。Conventionally, the stabilization of retaining walls in earth retaining works has been carried out by erecting raised struts or retaining anchors. However, in order to install the struts or retaining anchors, the roots are cut to a position where the struts or anchors can be installed, and then the struts or anchors are installed in order to stabilize the retaining wall. In this case, if you install a strut or anchor and then excavate below the location where the strut or earth retaining anchor is installed, the earth retaining wall will deform due to the excavation, and the load on the strut or earth retaining anchor will increase and the ground surface will deform. There was a downside to getting bigger.

All you have to do is to excavate the opposing ground l to a predetermined position, leaving . At this time, the belly riser may be installed at a predetermined position.

It is possible to repurpose the steel sheet piles.
