TL;DR: In this article, a concrete surface finishing apparatus equipped with a liquid membrane curing agent spray equipment for preventing a plastic crack is provided to minimize the required man power and to simplify the process by executing the leveling and compacting works about the concrete applied surface and the membrane curing agents spreading work about the leveled concrete surface at the same time.
Abstract: PURPOSE: A concrete surface finishing apparatus equipped with a liquid membrane curing agent spray equipment for preventing a plastic crack is provided to minimize the required man power and to simplify the process by executing the leveling and compacting works about the concrete applied surface and the membrane curing agent spreading work about the leveled concrete surface at the same time. CONSTITUTION: A concrete surface finishing apparatus equipped with a liquid membrane curing agent spray equipment for preventing a plastic crack includes a compaction equipment(1) and a spray equipment(2). The compaction equipment executes leveling and compacting works about the concrete applied surface. The compaction equipment includes a compaction unit(10), a traction frame(16), and a driving engine(18). The compaction unit is composed of a compaction plate(12) and a vibration unit(14). The compaction plate evenly compacts the concrete applied surface. The vibration unit is installed in the compaction plate to apply vibration to the concrete applied surface. The traction frame moves the compaction unit. The driving engine is mounted on the traction frame to supply the power to the vibration. The spray equipment is driven by remaining power of the driving engine of the compaction equipment. The spray equipment spreads the membrane curing agent on the leveled and compacted concrete surface.

TL;DR: A paver screed has a main screed with two outer side walls, at least one of the side walls being provided with insertion orifices for the releasable mounting of a lateral screed extension by means of fastening elements capable of being inserted through the insertionorifices as discussed by the authors.
Abstract: A paver screed has a main screed with two outer side walls, at least one of the side walls being provided with insertion orifices for the releasable mounting of at least one lateral screed extension by means of fastening elements capable of being inserted through the insertion orifices. A screed extension has fastening elements that comprise hydraulic cylinders which each have a piston that is spring-biased into an initial, retracted position. The cylinders are actuated by hydraulic fluid to displace or extend the piston against the biasing action of the spring. Preferably, the hydraulic cylinders are connected a hydraulic circuit of the main screed. The piston of each hydraulic cylinder carries a shank capable of being inserted through a proximal insertion orifice and which are preferably provided with an abutment element configured for attaching the cylinder to the sidewall of the main screed.

TL;DR: In this article, a rotating cylinder cement screeding system with a drive assembly and handle at one end for powering and controlling the system is described. But this system is not suitable for outdoor applications.
Abstract: A rotating cylinder cement screeding system (10) having a drive assembly (20) and handle (26) at one end for powering and controlling the screeding system. The rotating cylinder (12) is made of tubular screed rollers of varying lengths allowing a user to customize the length of the system to match a specific cement pour (18) . Further, each tubular screed roller is supplied with a male and female end for interlocking with each other and for receiving a variety of add on attachments such as an end pull, a slab drop down member, a footing member guide, a center anchor member and a counter rotation member. The rotating cylinder may also be equipped with a constant velocity type U- joint to allow the rotating cylinder to flex and thus, allow for pours with crowns or valleys, as needed by the cement installer.

TL;DR: In this paper, a ground surface parking lawn adopts green and the shortcoming of grass planting brick has effectively been solved to the grass planting check that can recycle, and the coverage rate on the lawn of parkking after it uses reaches 95%, bearing capacity and be 200Tm2.
Abstract: The utility model discloses a ground surface parking lawn, the basic unit, blotter and grass planting check, the basic unit adopts rammed earth, the blotter is for adopting sand cobble or rubble piece to roll the supporting layer of laying thickness and being 150~350mm, it is the coarse sand screed -coat of 50mm's particle?size?range at 10~30mm to lay thickness above the blotter, be equipped with sand / the sand and soil mixed layer of thickness for 150mm on the coarse sand screed -coat, sand / sand and soil mix layer upper berth and are equipped with the two -layer anti - geotechnological cloth of straining, counter straining sets up the grass planting check on the geotechnological cloth, and adopt the warp to plant the hole of the high quality topsoil packing grass planting check of fertilizer treatment. The utility model provides a ground surface parking lawn adopts green and the shortcoming of grass planting brick has effectively been solved to the grass planting check that can recycle, and the coverage rate on the lawn of parkking after it uses reaches 95%, bearing capacity and be 200Tm2, but becomes the parking area of bearing with the grass planting region, realizes lawn and parking area no. 2 and unifies, has improved afforestation environmental quality.
