TL;DR: In this article, the utility model discloses a stone material of preventing accumulation of salt in surface soil layer structure of mating formation, it includes: the stone material layer, the blind hole of two row at least parallels is seted up at its back, cement basic unit, it is pasted at the stone layer back, the landfill has the reinforcing bar at the perpendicular to stone material back in the ground basic unit.
Abstract: The utility model discloses a stone material of preventing accumulation of salt in surface soil layer structure of mating formation, it includes: the stone material layer, the blind hole of two row at least parallels is seted up at its back, cement basic unit, it is pasted at the stone material layer back, the landfill has the reinforcing bar at the perpendicular to stone material back in the cement basic unit, the reinforcing bar tail end extends to in the blind hole, the screed -coat, it sets up cement basic unit bottom spaced apartly in the screed -coat establish a plurality of cylinder holes, it has the chad to fill in the cylinder hole, cylinder hole top is uncovered setting, and a round hole is seted up to the bottom, ground basic unit, it lies in the bottom of screed -coat, it is inside be provided with connect in the pipeline of round hole, wherein, the stone material layer with still be equipped with at least one deck glass fiber cloth layer between the cement basic unit. It is simple, with low costs that layer structural design is mated formation to the stone material, had both shown the intensity that has improved the stone material layer and the requirement of permeating water, has effectively guaranteed the replenishment of groundwater resources again, and adaptability is wide, and spreading value is high.

TL;DR: In this paper, the authors proposed a method to enhance the quality of a dam main body by lowering a screed main body on a placing surface, temporarily storing it by uniformly filling mortar of a mortar hopper by reciprocatively moving a nozzle in a laterally long screed principal body by a nozzle moving means, and delivering a preset fixed quantity of mortar from a mortar delivery port together with the start of a movement of a vehicle.
Abstract: PROBLEM TO BE SOLVED: To enhance a quality of a dam main body by lowering a screed main body on a placing surface, temporarily storing it by uniformly filling mortar of a mortar hopper by reciprocatively moving a nozzle in a laterally long screed main body by a nozzle moving means, and delivering a preset fixed quantity of mortar from a mortar delivery port together with a start of a movement of a vehicle. SOLUTION: When a force feed pump 4 is driven, mortar is temporarily stored by being forcibly fed in a screed main body 8 through a flexible hose 5 and a nozzle 6. When mortar is forcibly fed, the nozzle 6 is reciprocatively moved over the total wide length in the screed main body 8 by a nozzle moving means 7, and the mortar delivered from the nozzle 6 is filled by a uniform quantity over its total length in the screed main body 8. Next, a door body 30 is opened by a prescribed quantity, and when a vehicle 1 is advanced, a necessary quantity of mortar is delivered from a mortar delivery port 9. COPYRIGHT: (C)1997,JPO

TL;DR: In this article, a floating screed is coupled together by a mechanism that moves the first section relative to the second section in a direction perpendicular to the planar bottom of the second.
Abstract: A floating screed device has a first section for cutting through plastic concrete and a second section for floating on the plastic concrete. The first and second sections are coupled together by a mechanism that moves the first section relative to the second section in a direction perpendicular to the planar bottom of the second section as the floating screed device is moved through a volume of unfinished plastic concrete.

TL;DR: In this paper, a vibrating screed for constructing a road and a gardening structure including a boundary stone pedestal and a side ditch, and a construction method of a structure using the same are provided.
Abstract: PURPOSE: A vibrating screed for constructing a road and a gardening structure including a boundary stone pedestal and a side ditch, and a construction method of a structure using the same are provided to form a side ditch and a boundary stone pedestal integrated structure, a boundary stone pedestal, a side ditch connected to one side of a boundary stone, etc. with one process, and to form a structure in the same shape in all sections. CONSTITUTION: A vibrating screed(100) for constructing a road and a gardening structure including a boundary stone pedestal and a side ditch contains: a molding plate(10) forming concrete, which is placed between a pair of forms(1) or a boundary stone and a form, in the shape of a side ditch and a boundary stone pedestal; a handle(20) connected to the molding plate to let a worker move the molding plate; and an aligner(30) supporting the molding plate to the form and aligning to move the molding plate regularly along the form.

TL;DR: In this article, the utility model has the advantages of simple and reasonable structure, the fertile groove of cancellation to avoid a series of drawbacks in fertile groove, waterproof performance strengthens, and it is whole that a revetment and underground structure wall even are an atress, gains in strength process simplification, constructionconvenience, reduction of erection time.
Abstract: The utility model discloses an underground structure outer wall HCMW worker method coincide wall, include: the cement mixing method wall, the cement mixing method wall includes a plurality of cement mixing method of interlock each other in succession, interval or insert in succession and be equipped with the reinforced concrete precast pile in a plurality of cement mixing method, the screed -coatsets up on the inner wall of cement mixing method wall, the underground structure outer wall, the underground structure outer wall sets up on the inner wall of screed -coat, the underground structureouter wall includes the reinforcing bar and mixes the concrete that has waterproof compacting agent, it is a holistic atress component to constitute through connection structure between cement mixingmethod wall and the underground structure outer wall. In this way, the utility model has the advantages of simple and reasonable structure, the fertile groove of cancellation to avoid a series of drawbacks in fertile groove, waterproof performance strengthens, and it is whole that a revetment and underground structure wall even are an atress, gains in strength process simplification, constructionconvenience, reduction of erection time.
