摘要： PROBLEM TO BE SOLVED: To provide a new asphalt (not a synthetic resin) protective sheet, in which deterioration due to hydrolysis, bacteria decomposition, etc., does not progress towards the inside of the weed-preventive protective sheet from a rear brought into contact with the ground surface of the weed-preventive protective sheet and weeds are not penetrated through the sheet for a prolonged term and grown. SOLUTION: The ground-surface slope-face weed-preventive protective sheet is composed of a surface layer 1 consisting of inorganic particles, an improved asphalt layer 2, a base material layer 3, to which weeds are not penetrated by the growth of weeds, the improved asphalt layer 4 and a rear layer 5 selected from a group made up of the film layer of a synthetic resin or a rubber and an inorganic particle layer. The base material layer is selected from a group composed of a layer obtained by impregnating and treating a woven fabric or a nonwoven fabric with a treatment having the melting poing of 200 deg.C or higher selected from a group consisting of the rubber and the synthetic resin and a layer acquired by laminating the woven fabric or the nonwoven fabric on both surfaces of a self-supporting film having the melting point of 200 deg.C or higher selected from the group made up of the synthetic resin and the rubber.

SOLUTION: On a front face 14' side of a flat plate 14', which serves as a restricting plate 14 and is provided with elasticity and plasticity of a Young's modulus of 300kgf/mm or more, grooves 16a', 16' with U-shaped cross sections are arranged in the positions for grooves 16a, 16b, while on the back face 14b' side, a sheet material 15' is bonded and layered, and as a result, a flat plate type member 11 is formed. The sheet material 15', in which magnetic powder magnetized so that to be provided with residual magnetic flux density of 25-15000 gauss is dispersed and mixed, serves as a magnetic layer 15. Then, the flat plate member 11' is formed into a side part vibration damping member 11 with asymmetric U-shaped cross section. The second part 11b" surface of the magnetic layer 15" is attracted to a rail R side face Rb side by means of magnetic force, and the first part 11a" and the third part 11c" are brought into tight contact with a jaw part Ra and a slanting face Rc by means of magnetic force. In this way, high vibration damping performance can be exhibited over a wide temperature range.

摘要： PROBLEM TO BE SOLVED: To prevent vibration of a columnar structure, and prevent crack and reduction of supporting force generated on a foundation ground caused by vibration so as to prevent collapse of a columnar structure by installing a vibration damping means on one part of the columnar structure. SOLUTION: An elastic damping body 3 is arranged as a vibration means so as to cover a base part on one part of a columnar structure 1. In order to increase a damping effect, elastic bodies whose hardness are different from each other are layered alternately with the elastic body singly or mixedly. In order to prevent vibration from transferring to a lower part, a same damping body 3 as a damping body 2 is arranged on the bottom surface lower part of the columnar structure 1 so as to shut out vibration. It is thus possible to prevent vibration of the columnar structure, and prevent crack and reduction of supporting force generated on a foundation ground caused by vibration so as to prevent collapse of the columnar structure. Also it is possible to prevent vibration environment pollution by preventing vibration from transferring to the foundation ground caused by low frequency ground vibration.

摘要： PURPOSE: To effectively interrupt the propagation of low frequency ground vibration by forming an airtight chamber within an excavated channel with a specified distance kept along a vibration generating structure, and filling air into the airtight chamber up to a specified pressure level. CONSTITUTION: A channel 2 is excavated to the depth of a foundation ground as a rule in a space with a specified distance kept along a vibration generating structure 1 generating low frequency noise such as expressways, railway facilities and the like. The wall surface 4 of the channel 2 is then formed out of concrete and steel members, and the wall surface is internally packaged with pressure proof members composed of steel plates and the like. Each pressure proof member 5 may be so constituted as to be divided in the vertical direction depending on the depth of the channel. Next, membrane members 9 and 9 made of rubber are mounted on the upper opening section and bottom section of each pressure proof member 5, and its inside section is thereby formed into an airtight chamber 3. The airtight chamber 3 is then communicated with an air tank 13 through an inner pressure sensor 14, an adjusting valve 15 and the like, and air is filled in the aithtight chamber 3 up to a specified pressure level.

摘要： PURPOSE:To effectively perform freeze proofing of a trolley wire without worsening its function by using a synthetic resin foaming material, and coating a peripheral surface of the trolley wire so as to expose the lowest part of the trolley wire peripheral surface. CONSTITUTION:This freeze-proof structure for a trolley wire is formed by using a synthetic resin foaming material 2 of closed cell structure having at least flexibility, and by coating the trolley wire 1 so that the lowest part of a peripheral surface of the trolley wire 1 is exposed to the outside. Preferably the outside of the synthetic resin foaming material 2 is coated with a protecting material 3 of metal or the like. Thus by effectively preventing freezing and also by protecting the synthetic resin foaming material 2 as a heat insulating material from its damage, deterioration, etc., a freeze proofing effect over a long period is maintained. In the synthetic resin foaming material 2, in the case of using a trolley wire provided with a groove 8 in the trolley wire, a fixing protrusive part, engaged with the groove 8 of the trolley wire, is provided as necessary in a trolley wire side of the foaming material.

摘要： PURPOSE:To provide a sound absorbing structural body for slab track excellent in all of strength, rigidity, electric insulation and sound absorbing performance. CONSTITUTION:Outer sound absorbing material blocks 10 are arranged on a concrete slab 3 by using first support frames 9, 9 in such a manner that voids are formed between the concrete slab 3 and the outer sound absorbing material blocks 10. Inner sound absorbing material blocks 14, 14 are arranged by using second support frames 12, 12 and a central support frame 13 in such a manner that voids are formed between the concrete stab 3 and the inner sound absorbing material blocks 14, 14. Accordingly, sound absorbing performance is exhibited to the maximum. This can withstand not only damage due to a negative pressure estimated to be 0.02 kg/cm at the time of high speed vehicle passing but also impact force of an ice block dropped from a traveling train. Installation work thereof onto a track is simple, and replacement for maintenance work as well as maintenance and repair becomes extremely easy.

摘要： PURPOSE:To prolong the life of a rubber tire by restraining the abrasion of the rubber tire without increasing body weight. CONSTITUTION:Many short fibers 5, 5... which are arranged along the radial direction of a rubber tire, are buried in the circumferential part of the tread 2a of the tire, which is rotated by its landing when it lands on the track from the situation of being floated above the track without rotation, so that the top ends of the short fibers 5, 5... are exposed to the surface of the tread 2a when the tread 2a is a little abraded. With this structure, the abrasion of the tread 2a can be restrained to prolong the life of the rubber tire.
