摘要： PROBLEM TO BE SOLVED: To prevent lowering in the durability of block lining after repair by preventing occurrence of joint cavities in joints, and to facilitate execution of construction of a structure for draining leaked water without lowering the durability of the block lining.
SOLUTION: The joint portions with reduced thickness occurred in the joints 14 of the block lining 12 are cleaned, and a joint material 16a of a first layer is filled in the cleaned joint portions with reduced thickness. Then, stainless metal fittings 24 formed in a clip shape are mounted in the joint portions with a part of the respective metal fittings elastically deformed to be embedded in the first-layer joint material 16a, and a joint material 16b of a second layer is filled in the joint portions in which the metal fittings 24 are mounted. In case the water leaks from the block lining 12, a hose for water drainage is placed in the joint portions within a range where the water leaks, and then the first-layer joint material 16a, the metal fittings 24 and the second-layer joint material 16b are filled in the joint portions, so as to have a structure with the hose for water drainage embedded in the joint 14.

摘要： PROBLEM TO BE SOLVED: To provide an earth pressure reducing method ensuring the effect of reducing earth pressure on an embedded structure such as a culvert and allowing easy construction work. SOLUTION: A culvert 1 is constructed on foundation soil BG and side banking soil portions GR, GL appropriately higher than the top plate 1a of the culvert 1 are built on both sides of the culvert 1. A non-consolidated earth layer GC which either has a banking thickness smaller than the depth of a valley or is hardly consolidated is formed on the top plate 1a. A steel plate 2 is laid across the upper surfaces of the side banking soil portions GR, GL to cover the valley immediately above the culvert 1 from its top. An appropriate gap δ is thereby formed between the steel plate 2 and the non-consolidated earth layer GC. Next, an upper banking soil GU is built on the tops of the side banking soil portions GR, GL and the steel plate 2. The vertical earth pressure of the upper banking soil GU on the culvert 1 is insulated by the steel plate 2 and the gap 3.

摘要： PROBLEM TO BE SOLVED: To improve a relieve effect for a vertical earth pressure exerted on the top plate of a culvert and to reduce material cost for reduction of the vertical earth pressure. SOLUTION: After a work for a culvert 10 is executed, a number of waste tires 20 are laid on a top plate 11, and side earth shield plates 40 are erected on both sides thereof. Upper earth shield plates 30 are laid above waste tires 20, and by scattering a fill material after covering with an engineering sheet 50 and carrying out rolling compaction, a given height filling ground in which the culvert 10 is buried is formed. When, at a process of land formation, upper loading from a filling ground material has reached a given value, the tire 20 is buckled and the height thereof is rapidly decreased. Thereby, a ground arch GA is formed including a projected underground discontinuous surface rising upward from the two edges in the width direction of the top plate 11.
