摘要： APPARATUS FOR MEASURING AN IRREGULAR SURFACE OF A DEPOSIT IS COMPRISED BY A PERFORATED OR GRID SHAPED CIRCULAR OR POLYGONAL FLAT PLATE OR FRAME STRUCTURE WITH A MEASURING POINT AT THE CENTER THEREOF AND A LAYER OR TETRAPODS DEPOSITED ON THE IRREGULAR SURFACE, ALL OF ONE SIZE WHICH IS SUCH THAT THE FRAME MEMBER WILL COVER AT LEAST TWO

OF THEM, TO OBTAIN BY SOUNDING THE LAYER WITH THE FRAME A RELIABLE MEASUREMENT OF THE GENERAL CONFIGURATION OR ENVELOPE OF EXTREMLY IRREGULAR SURFACES. THE TETRAPODS MAY BE INCORPORATED IN A STRUCTURE WHICH IS BUILT UP ON THE IRREGULAR SURFACE, AS IN REPAIRING A BREAKWATER.

摘要： A wave dissipating wall is formed of a plurality of wave chambers comprising a plurality of horizontal plates and vertical partition walls opening toward the direction from which waves come in. The ends of the walls dividing the chambers are wider than the remaining parts of the walls and the front walls comprise semi-circular curved surfaces extending toward the direction from which the waves come in order to introduce the waves into the chamber having a wider width than the entrance formed between the respective front walls and to let the waves circulate within the chamber by the energy of the waves, thereby increasing the friction resistance between the waves and the walls as much as possible and achieving an efficient diminishing of the wave energy.

摘要： A process for the formation of an artificial seaweed bed comprises depositing a structure as an artificial fish reef in the sea. According to the present invention, the structure is made of a glassy material having a specific composition, or a surface of the structure is covered with the specific glassy material. The glassy material contains silicon in an amount of 30 to 70 wt. % in terms of SiO2. The glassy material further contains sodium and/or potassium in an amount of 10 to 50 wt. % in terms of Na2O and/or K2O. The glassy material furthermore contains iron in an amount of 5 to 50 wt. % in terms of Fe2O3. All or a part of the iron is present in a ferrous state. The glassy material contains the ferrous iron in an amount of not less than 1 wt. %.

摘要： A stair-like revetment structure is formed by using sloping blocks. At the rear end of the block main body having an approximately rectangular and rearward sloping flat step are provided rear engagement pods opening like a wedge at the rear of the main body and front engagement pods having an approximately same shape as the rear engagement pods via a concave portion at the center bottom of the front of the main body, the concave portion being provided between the front and the rear engagement pods, to thereby decrease cost by simplified structure. Thus structured sloping blocks are arranged next to each other on a sloping foundation, and the front engagement pods of the sloping blocks of one layer is inserted into the engagement concave portion between the rear engagement pods of the adjacent block to successively cover the sloping foundation in a zig-zag and step-wise fashion, to thereby form a water passage with the concave portion of the upper layer sloping blocks and the engagement concave portion formed between the rear engagement portion of the sloping blocks of one layer below. The revetment structure can secure the safety of users since there are not exposed projections, holes, etc. on the stair-like steps.

摘要： PURPOSE:To obtain a water current type oil recovery apparatus which recover oil from waste water containing oil which is floating on water utilizing relative currents. CONSTITUTION:In a water current type oil recovery apparatus 10 in which waste water containing oil is introduced into an apparatus main body utilizing relative currents which are generated by the advance of a hull, purified water is discharged after the oil being recovered from waste water, a non-power type negative pressure generating means is installed in the purified water discharging opening, and a negative pressure zone is formed near the outside of the opening. In the apparatus 10, since purified water is discharged forcibly by being sucked constantly after oil being recovered by the action of the negative pressure zone formed by a non-power type negative pressure generating means 16, a large amount of waste water can be introduced, and oil recovery work can be done efficiently.

摘要： PURPOSE:To make efficient work by driving bearing piles of a starting section firstly by an operation machine on the ground to fix beam members and a floor slab and, at the same time, moving the operation machine to the starting section to construct successively thereafter one span after another. CONSTITUTION:First of all, bearing piles 16 for a starting section 12 are driven from the ground, a floor slab 26 equipped with a vertical beam member 22 and a horizontal beam member 24 manufactured in advance is fixed on the bearing pipes, and an artificial ground is formed. After that, an operation machine 14 equipped with a pile driving device, a crane, etc., is moved to the starting section 12, and after next bearing piles 30 are driven, precast beam members 32 and a floor slab 34 are fixed. The same work is successively repeated in the following, the artificial ground is constructed one by one span, and lastly cast-in-place concrete, etc., are placed on the floor slab to finish. According to the constitution, work can be simplified, and a construction period can be reduced.
