摘要： PROBLEM TO BE SOLVED: To provide a method of watertightly sealing an element joint portion, which allows the operator to carry out sealing work of the element joint portion even in a quick manner, without entering the interior of an element, to thereby improve the efficiency of the work.
SOLUTION: The method of watertightly sealing the element joint portion between the mutually adjacent component elements of an element structure which is constructed as a structure crossing under a route or an element abutment. According to the method, a work truck for traveling in the element having the joint portions is provided, and while the work truck travels along the joint portion, residual sediment adhering to the joint portion is removed by means of a tool provided for the work truck to clean the joint portion, and thereafter a sealing material is sprayed to the joint portion to seal the same.

摘要： PROBLEM TO BE SOLVED: To provide a sufficient water stop measure in a construction method cutting a natural ground by a flexible cutting tool such as a wire saw and inserting steel plate and the like into a cut portion.
SOLUTION: A guide pipe in which the flexible cutting tool such as the wire saw is inserted is installed along the periphery of a planned structure. The flexible cutting tool such as the wire saw is inserted over two adjacent guide pipes, thereby cutting the guide pipes and the natural ground between those. A water-stopping steel plate or sheet material formed with a joint at a side portion is inserted in a cut portion, and connected to the water-stopping steel plate or sheet material previously inserted using the joints in the guide pipe. The water-stopping steel plate or sheet material is installed along the periphery of the planned structure. In this construction method, the connecting portion of the joints in the guide pipe is filled with plastic material to stop water.

摘要： PROBLEM TO BE SOLVED: To provide a method for protecting a joint of an element for constructing an underground structure, which can surely prevent sediment etc. from flowing into a joint section in the insertion of the element, even if a construction distance is long.
SOLUTION: A protective board 17 is arranged in joints 6 and 9, which are fitted into the joints of lining elements for being inserted into natural ground later, among the joints of the lining elements for being precedently inserted into the natural ground, in such a manner as to cover an opening 16 along the longitudinal direction of a fitting groove 15. The protective board 17 is held by first and second protective sheets 18 and 19 which are each fixed and arranged along the longitudinal direction between both surfaces of the joints 6 and 9 and the protective board 17. The protective board 17 is disengaged from the joints 6 and 9 along with the fitting of the joints 6 and 9 of the preceding lining element with the joint of the following lining element. Thus, the joint of the following lining element is sandwiched between the respective longitudinal ends of the first and second protective sheets 18 and 19.
