摘要： PROBLEM TO BE SOLVED: To ensure work space in the water by removing mud deposited on the bottom of water without a problem of water contamination by use of a structure which is good for work execution and can be easily removed after the completion of works in the case of constructing a bridge pier. SOLUTION: Corrugated sheets 17 with a radius enough for ensuring the work space in the water are connected to each other in the horizontal circumferential direction and in the vertical direction to assemble a corrugated pipe 18, and a knife edge member 19 made by a steel plate is fixed to the lower end of the corrugated pipe 18 to construct a water mudiness preventing steel frame. The steel frame is set in the mud 14 at the bottom of the water, thereby removing mud in the range surrounded with the steel frame. This setting of the steel frame and removal of mud 14 are performed until reaching the top of the foundation 13. In the case of ensuring the work space 1 in the water in the periphery for reinforcing the existing underwater bridge pier 11, the corrugated pipes 18 are assembled in such a manner as to surround the underwater bridge pier 11.

摘要： PURPOSE:To dismantle and recover steel cutting edges after excavation of a shaft, to prevent liner plates from buckling by ration force of a jack, and to prevent earth-flow into the shaft from the space between cylindrical steel cutting edges and a cylindrical liner unit. CONSTITUTION:Steel cutting edges. Divided steel cutting edges 2a, 2b, 2c and 2d are assembled and arranged along a shaft wall of a shaft, which has been excavated to some extent of depth. And liner plates 12 are arranged therein and connected in a stagger fashion to form a cylindrical liner unit, and buckling- prevention materials 14 are squeezed into the bottom line of liner plates and a jack 15 is placed between the bottom of the liner plates 12 and the cutting edge bodies of the steel cutting edges. The divided steel cutting edges are pressure-fitted into the bottom of the shaft one after another by the jack, and after excavation of the earth and within the steel cutting edges new liner plates are connected to the bottom line of the liner plates in a fashion to form a cylindrical liner assembly, and after excavation to the specified depth is completed, the steel cutting edges are dried and dismantled and a catchment well is constructed.

摘要： PROBLEM TO BE SOLVED: To reduce the number of standards required with respect to the arrangement of joining bolt holes for connected plates even though the numbers of the divided upper and lower plates to be connected are not the same at the expansion bottom portions where the diameter is enlarged at the bottom portion of the assembled vertical shaft where the bolt jointing is performed by butting the liner plates in upper, lower, right and left directions. SOLUTION: These divided type donut-shaped connecting plates for vertical shaft bottom-expansion structures are formed to a vertical shaft by jointing liner plates together with bolts, where two rows of inner and outer peripheral jointing bolt holes 2a, 2b are provided with the arrangement having the same diameter as those of the jointing bolt holes in the flange in peripheral direction of the liner plate of two kinds of sizes connected to the upper and lower portions of the expanded bottom portion, and inner peripheral or outer peripheral jointing bolts 2a, 2b have long holes in the peripheral direction.

摘要： PROBLEM TO BE SOLVED: To make up for the shortage of tensile strength when having assembled a vessel or a bank with a liner plate. SOLUTION: A notched area whose shape is preferably designed to prevent a strip from coming off, is provided in one to three locations along the groove on the outer periphery of a flange in the axial direction of a liner plate 1. This liner plate 1 is jointed with a bolt in every direction, thereby forming a cylinder-shaped structure. The strip 2 is wound up along the groove on the outer periphery of the liner plate 1 and fastened. The strip 2 is so shaped that it may run along the groove of the outer periphery of the liner plate 1. Favorably, the strip 2 is connected with an anchor member which slants a bearing surface and a through hole in conformity with the direction of the strip 2 and fastened. So as to uniform the tensile force, the strip 2 is connected in a plurality of locations on the outer periphery and fastened. The number of winding of the strips 2 is reduced at the upper part while it is increased at the lower part. This construction makes it possible to reduce the number of bolts used when they are jointed to a satisfactory extent.

摘要： PROBLEM TO BE SOLVED: To provide an economical steel slit dam which can positively arrange a steel pipe column member that should be arranged on a downstream side, on the downstream side, and can positively arrange the steel pipe column member that should be arranged on an upstream side, on the upstream side.
SOLUTION: The steel slit dam 14 is constructed of skeleton structures each having the upstream-side steel pipe column member 1 and the downstream-side steel pipe column member 4 which are inclined so that their upper portions are brought close to each other and their lower portions are separated from each other, and horizontal members 2 connecting the steel pipe column members. According to the structure of the steel slit dam 14, an inclination angle A of the downstream-side steel pipe column portion 1 is set steeper than an inclination angle B of the upstream-side steel pipe column member 4, and in this manner, the sloping gradient of the upstream-side steel pipe column member 1 is made different from that of the downstream-side steel pipe column member 4.
