摘要： PURPOSE:To substantially increase the capability of forced feed by providing a compressed air supply means for feeding the compressed air from the upstream side of a squeeze type pump for applying delivery pressure to a viscous forced feed material. CONSTITUTION:For the forced feed of viscous material, the compressed air is supplied from an air compressor 1, with an air feed valve 9a and a soil forced feed pipe open/close valve 11a opened, and an air discharge open/close valve 10a closed. Also, a squeeze pump 7 is driven and the forced feed of the viscous material is performed therewith under assistance of an extruding force with the compressed air. Furthermore, the compressed air is supplied from the compressor 1 to a nodulizing agent reservoir tank 5. The compressed air so supplied is utilized and a centrifugal pump 6 is driven for the forced feed of nodulizing agents. According to the aforesaid construction, force feed capability can be substantially increased.

摘要： PURPOSE:To mix a fixed quantity of cement and a fixed quantity of aggregate reliably with each other, by a method wherein the aggregate dissociated within a dissociation case is loaded onto the cement to be loaded within a mixing case from a sending-out port. CONSTITUTION:A mixing case A1 is arranged on a belt conveyor 50 through a base rest A2, a meter 1 for aggregate is arranged on the upper part of the mixing case A1, a cement quantitative holding vessel 20 is adjoined to the side of the mixing case A1 and an aggregate dissociation mechanism 10 is arranged between the mixing case A1 and the meter for the aggregate. Then cement within the cement quantitative holding vessel 20 is loaded into the mixing case A1 from a sending-out port 23 of the tip of a communication path 22 through a conveying device appropriately. Then the aggregate of the meter 1 for the aggregate is loaded into a case 11 for aggregate dissociation of the aggregate dissociation mechanism 10 from an opening part 2, dissociated so as to dissociate the aggregate by a rotating rotator 15 for dissociation, loaded onto the cement which is loaded continuously within the mixing case 1 and mixed up evenly with each other.

摘要： PURPOSE:To carry out a smooth spray work, by forcing to feed a material sprayed for ground stability to spraying nozzle and feeding filamentous materials for mixing by compressed air toward the front end side within a guide hose and mixing the filamentous materials with the sprayed materials. CONSTITUTION:This device is composed of a connected feeding mechanism 11 holding synthetic resin filamentous material, a nozzle 10 to feed the filamentous materials, a compressor 12 and a guide hose 13. A material sprayed for ground stability is blown from a spray nozzle 4 by use of the compressed air from a compressor 2 by a sprayer 1 and the filamentous material is fed from the mechanism 11 to the nozzle 10 is projected into the hose 13 by the compressed air from the compressor 12 to feed the filamentous materials into the nozzle 4 from the front end of the hose 13 for mixing the materials to be sprayed. Therefore, the filamentous materials can be fed securely and smoothly.

摘要： PURPOSE:To make the spray work easy and efficient and increase the fixing property of a sprayed object by continuously feeding a mixing thread-shaped object from a mixing guide body fitted to the fitting hole of a mixing case inserted into a sprayed object feed path. CONSTITUTION:A mixing case 1 is provided on a hose 22 connecting a spray machine and a spray nozzle via fitting section s 10 and 11, and a mixing guide body 2 with a through hole 2a is reciprocatably fitted to a fitting hole 12 bored on the peripheral wall of the case 1. A sprayed object is fed to a sprayed object feed path in the case 1 from the spray machine via the hose 22, and high- pressure air and a high-pressure liquid are fed to the feed path of th case 1 from a gap between a guide body 2 and a guide tube 4 through a feed port 14 via a hose 23. A mixing thread-shaped object T inserted into the through hole 2a of the guide body 2 is fed to the feed path and mixed with the sprayed object, and the mixture is sprayed to the desired position from the spray nozzle via the hose 22.
