摘要： PURPOSE:To efficiently provide homogeneously cured body by long-distance forcible feeding by mixing a rapid setting admixture formed by compounding inorg. fine powder contg. siliceous component with a compd., such as calcium aluminate and cement and fine aggregate, etc. CONSTITUTION:A cement bituminous mortar A liquid is obtd. by mixing water, defoaming agent and setting control agent, adding a bituminous emulsion and high-polymer emulsion to the mixture, compounding ordinary cement, sand and aluminum powder therewith and kneading the mixture by a mixer. A quick curing slurry B liquid is then obtd. by mixing the water and the curing control agent, adding the quick curing admixture to the mixture and kneading the mixture by the mixer. The resultant liquids A, B are fed to a grouting site by forcible feeding pumps A, B of respectively separate systems. The front ends of hoses for the liquids A, B are then connected to a continuous mixer and the liquids are kneaded, by which the quick curing cement bituminous grouting material for railways is produced. This grouting material is poured into ballast via a grouting funnel, by which the packing installation is executed.

摘要： PURPOSE:To prevent the irregularity of a track by scattering or impregnating a stabilizing material such as a cement group grout material, a bituminous emulsifier, a cement bituminous grout material or the like to ballast just under the packed layer of the labor-saving track. CONSTITUTION:An impregnating pipe 7 is disposed into ballast 5 just under a packed layer 3 mounted to an existing-line labor-saving track. A cement grout material, in which a high-molecular emulsion is mixed into cement mortar, etc., is infiltrated into the ballast 5 through the holes 8 of the impregnating pipe 7 from an impregnating funnel 9. A bituminous emulsion or a cement bituminous emulsion can be used in place of the cement grout material.

摘要： PURPOSE:To obtain a device at a low cost, which has the excellent characteristic for controlling the ratio of the liquid B to the liquid A. CONSTITUTION:Flowmeters 8, 22 of the liquid A and the liquid B are provided separately between force-feed pumps 7, 21 and a confluence point, and the flow-rate of the liquid B is adjusted in response to the flow-rate of the liquid A so as to control the flow-rate ratio at a specific value. At the time of adjusting the flow-rate of the liquid B, an upper and a lower limit are provided in relation to a flow-rate reference set value, and in the case where the flow-rate is changed between the upper and the lower limit, revolution of the force-feed pump 22 of the liquid B is controlled on the basis of the flow-rate reference set value, and in the case where the flow-rate is out of the upper and the lower limit, fixation of the flow-rate reference set value is cancelled to control the revolution of the force-feed pump 22 of the liquid B on the basis of the proportional integration control quantity in relation to the flow-rate reference set value.

摘要： PROBLEM TO BE SOLVED: To obtain good construction workability and satisfactory development of strength for both of the newly-laying railway and the existing railway by using different and more suitable setting modifiers separately in the grouting material of cement-bitumen for new and existing railways on high-temperature construction execution work for railways. SOLUTION: In a cement-bitumen grouting material on high-temperature execution work for railways, different additives are separately used for the newly laying railway (1) and the already laid railway (2), as will be described below. (1) For the newly laying railway, an inorganic fine powder mainly comprising a normally hardening calcium sulfoaluminate as a shrinkage- compensating admixture and, as a setting modifier, is used a formulation mainly comprising a modified methylol-melamine condensate and a modified lignin of delayed high-performance water reducing agent. (2) For the existing railways, an inorganic fine powder mainly comprising a formulation of a quick hardening calcium aluminate and gypsum and a silica component is used as a shrink- compensating admixture and a combination of a formulation of inorganic salts and organic acids with a delayed high-performance water reducing agent used in (1) is used as a setting modifier.

摘要： PURPOSE: To improve damping properties by adding open-cell urethane foam chips formed through crushing closed-cell urethane foam an industrial material consisting essentially of cement and asphalt. CONSTITUTION: This industrial material is produced by: (I) crushing urethane foam selectively separated from industrial waste or waste materials to convert the closed-cells in the urethane foam into open-cells, and concurrently, to form urethane foam chips; (2) then, mixing cement-asphalt mortar consisting of 100 pts.wt. of asphalt, about 30 to 100 pts.wt. of cement and about 1 to 10 pts.wt. of a plasticizer such as water with about 5 to 40 pts.wt. of the open-cell urethane foam chips having about 1 to 4mm chip size in diameter by using a mixer or the like; (3) thereafter, dehydrating the resultant mixture and molding the dehydrated mixture into a cement-asphalt hardened body. This hardened body has a structure in which a cement-asphalt mixture penetrates into the inside of each of the open-cell urethane foam chips dispersed within the body and is stuck there. Accordingly, the objective industrial material whose destructive bending strain, vibration-damping properties and water permeation inhibitory properties are remarkably improved with increasing the content of the open-cell urethane foam chips in the material, can be produced.
