摘要： PURPOSE:To accurately judge whether or not the drilling direction of a hole is on a perpendicular line by providing a drill pipe which is driven to rotate, a cutting means which is fixed to one end part of the pipe, and inclinometers fitted to one end part of the drill page. CONSTITUTION:While the hole 16 is drilled, both inclinometers 28 receive equal centrifugal force generated by the rotation of the drill pipe 12 on condition the axis of the drill pipe 12 is perpendicular and output an equal value. When the axis of the drill pipe 12 is not perpendicular, on the other hand, both inclinometers 28 slant together wit the drill pipe 12 and the output values of both inclinometers 28 are different. It is confirmed whether or the drill pipe 12 is perpendicular, namely, whether or not the hole 16 is drilled perpendicularly by checking whether or not the outputs of both inclinometers 28 is equal.

摘要： PURPOSE:To recover floating dust, etc., on water surface by utilizing head differences by a method in which an intake tower having an opening in its water surface portion is set in sea or lake and the bottom of the tower is connected with a bottom tunnel having a water supply pump on its outlet leading to a reservoir. CONSTITUTION:An intake tower 4 is set in sea or lake 1, and a slit opening 5 is formed in the water surface portion of the tower 4. The bottom of the tower 4 is connected with a bottom tunnel passage 9 having a water supply pump 10 in its tip portion. Water and suspended substances introduced into the tower 4 are supplied through the passage 9 to reservoir 2, where there is a difference of water level between the reservoir 2 and the open sea 1. When the open sea 1 is high, the cofferdam gate 3 is closed and the gate 3a on the reservoir 2 side is opened to allow water to flow naturally to the reservoir 2 side. Also, when the water level is low, the water of the reservoir 2 is allowed to flow to the open sea 1 by the head difference by reversed procedure. A box-like structure or excess ship, etc., is further used and the head difference is also utilized to recover suspended substances without power.

摘要： PURPOSE:To introduce the clean water of open sea without power by a method in which a water reservoir is provided on the upper end of a sloped ground to store the open sea water collected in a converging dam, and a water conveyance tunnel is provided between the reservoir and the water-drainage place to freely drop the water into the water-drainage place. CONSTITUTION:A converging dam 4 to collect tidal current on the open sea 1 side is set at a given angle toward the direction of open sea, and a sloped part 5 on which tidal current is directed is provided toward the inside bottom of the dam 4. A water reservoir 7 is formed on the upper end side ground of the sloped part 5 to store open sea water collected in the dam 4. A coffer dam 10 is also provided on the inner harbor 2 side by forming a water conveyance tunnel 9 between the reservoir 7 and the harbor 2 in such a way as to freely drop the water of the reservoir 7 into the conveyance tunnel. The clean water of open sea can thus be directed into the water-drainage place without power at low cost, raising its utility effect.

摘要： PROBLEM TO BE SOLVED: To utilize a bank body as a pier for emergency by installing hollow cases charged with ballast on the submarine foundation and scattering natural stones at both sides to construct an embankment and discharging ballast in an emergency to float the cases and tagging them for mooring or anchorage. SOLUTION: An air supply and exhaust hole 24 and a manhole 21 are provided at the top face of a case body 20 made of concrete, a single steel material, or a synthetic material and a water supply and discharge hole 26 is provided at the bottom thereof. This case body 20 is put on a foundation constructed in advance in the submarine construction site. Valves 28, 30 are opened to charge ballast and water to submerge the case body and settle it on the foundation. A number of natural stones are scattered at both sides of the case body to stack them and construct an embankment. Even when the natural stones of the embankment collapse owing to an earthquake, a tsunami, or the like, since the case body is not probably broken, the natural stones at one side are removed and the valves 28, 30 are opened and the ballast and water are removed to float the case body 20 and tag it to the other place. The case body is moored or settled on the bottom to form a pier for transportation boats of aid materials. When sand is used as the ballast, it is fed or discharged through the manhole 32.

摘要： PURPOSE:To maintain the purifying function of a channel for a long period by preventing an extending conglomerate layer from clogging with sludge and the like. CONSTITUTION:A filter member 11 comprises suspended materials such as foaming styrene, wood chips, hollow glass balls, plastic balls. Therefore, the filter members 11 undergo the effect of water flow and are rubbed with each other, so that sludge adhering to the filter members 11 gradually falls off from the surfaces of the filter members 11 and is accumulated in a sand pit 15. If the suspended filter members 11 are recovered from an opening part 17 by employing the transportation effect of water flow, cleaning work such as taking out the sludge accumulated in the sand pit 15 is facilitated.

摘要： PURPOSE:To increase the activity of microorganisms by preventing decrease in dissolved oxygen in water throughout a cleaning water channel. CONSTITUTION:A shoal 21 is installed in the boundary part between the first pebbel layer 11 and the second pebbel layer 12 to make the depth of a part of a water channel extremely shallow so that a turbulent water flow is produced. The remarkable turbulence of water surface increases the air intake effect. Moreover, the turbulent water flow effect due to projections 22 fixed on the bottom of the shoal 21 and sheathing boards 23, 24 fixed on the boundaries between the shoal 21 and the respective pebbel layers 11, 12 contributes to the intake of oxygen in the air into the water of the river.

摘要： PURPOSE:To make efficient power generation possible in a simple structure by constituting it so as to generate electric power by means of an electromagnetic inductive action between a magnet installed in a float and a coil confronted in close proximity to this magnet by this float's up-and-down motion due to waves. CONSTITUTION:When a wave generating set 11 is set up on a seashore slope 10, there are provided with a convergent bank 12 consisting of a convergent part 14 spreading in a flare-form toward an offing from the vicinity of a waterside line 13 and a training part 15 of constant width extended as far as the upper part of the slope 10 from the rear of this convergent part 14. A float 23 moved up and down by waves along a guide shaft 18 is housed in this training part 15, and a magnet 24 is installed on the bottom part. In addition, extending over a moving range of this float 23, a coil 22 composed of winding an electric wire 21 on a reel 20 standing face-to-face with this magnet 24 through a clearance is laid down there. Then, an electromotive force is made so as to be generated by an electromagnetic inductive action in the coil 22 cooperating with the magnet 24 through the float's vertical motion due to waves.
