路缘石滑模施工工法
路缘石滑模施工工法
Slipform construction method of road edge stone
1 前言
1 Preface
随着我国高等级公路的飞速发展，全面推行机械化施工，是大势所趋，这对于提高施工质量，加快施工进度有着重要作用。预制法路缘石施工主要是把预制好的路缘石砌在路肩预挖的沟槽中。施工进度慢、工序多、占用场地大，路缘石的整体强度差、线条不顺畅。滑模施工法是采用路缘石滑模机在施工现场将新拌路缘石材料连续现浇．并密实成型．每天可铺筑1500m左右。滑模法铺筑路缘石速度快、所需人工少、不需要预制场地，铺筑的路缘石整体结构强度高、线型顺畅美观，倍受施工单位和业主的青睐。
With the rapid development of high grade highway in our country, it is the general trend to carry out mechanized construction in an all-round way, which plays an important role in improving the quality of www.bdwjmc.com www.yimilange.com www.aoerjiamenchuang.com www.bdfscl.cn www.zkzscl.com www.keshun0312.comconstruction and speeding up the construction progress. Prefabricated road curb construction is mainly made of precast curb stone in the trench excavated on the shoulder. The construction progress is slow, the process is much, the occupying site is large, the overall strength of the curb is poor, and the lines are not smooth. The slipform construction method is to use the slippery stone slipform machine to continuously pour the new curb stone material at the construction site, and to form it densely. It can lay 1500m every day. The sliding mode method has the advantages of fast speed, less manpower and no need for precast sites. The overall structure of the paved road stone is of high strength and smooth and beautiful line type. It is favored by the construction units and the owners.
2 工法特点
2 characteristics of industrial law
与先预制后安装方法相比，本工法能够提高路缘石内在的施工质量：路缘石强度高、平整度好、线形顺直、美观大方、整体稳定性好。同时加快施工进度缩短了工期，节省人力物力，能节约20-30%的成本。 节约能源消耗，经济效益也不错。
Compared with the prefabricated installation method, this method can improve the internal construction quality of the road edge stone: high strength, good smoothness, straight line, beautiful appearance and good overall stability. At the same time, speeding up the construction process shortens the construction period, saves manpower and material resources, and saves the cost of 20-30%. Energy consumption is saved and economic benefits are good.

This construction method is suitable for the construction of various grades of highway curb stone.
4 工作原理
4 working principle
根据工作原理的不同，路缘石滑模机主要分为挤压式、振捣式、锤捣式和振动式。
According to the different working principles, the sliver slipform machine is mainly divided into extruding, vibrating, hammering and vibrating.
挤压式路缘石自动成型机的工作原理是：混合料被螺旋推进器或往复缸不断地推入成型模具，并充分地挤满，混合料内部产生一定的挤压力。形成具有一定密实度、强度及一定形状的路缘石。在路缘石形成的过程中，混合料对螺旋输送器的水平反力传给机架、行走轮，使整机沿路面前进。
The working principle of the extruded edge stone automatic molding machine is that the mixture is continuously pushed into the molding mold by the spiral thruster or reciprocating cylinder, and it is fully packed, and a certain extrusion pressure is produced inside the mixture. The formation of a certain degree of compaction, strength and certain shape of the curb. In the process of forming the curb, the horizontal reaction force of the mixture to the screw conveyor is transmitted to the frame and the walking wheel to make the whole machine move along the road surface.
锤捣式路缘石滑模机的工作原理是：在滑模机成型模具的前面安装有锤捣装置，该系统将混凝土锤捣挤压进入与主机相连的成型模具里；机器的行走是靠自撞锤运动的反作用力。
The working principle of the hammer sliding pattern machine is that a hammer device is installed in front of the molding die of the sliding mode machine. The system makes the concrete hammer pressed into the molding die connected with the main engine; the machine is walking by the counterforce of the movement of the crash hammer.
振捣式路缘石滑模机的工作原理是：在滑模机成型模具的前面加有振捣棒，通过振捣棒的作用使水泥混凝土达到一定的密实度。
The working principle of the vibrating roller sliding mode machine is that the vibrating rod is added to the front of the molding die of the sliding mode machine, and the cement concrete is compacted to a certain degree by the action of the vibrator.
振动式路缘石滑模机的工作原理是：在模具上安装一个高频低幅的振动器，通过振动器使水泥混凝土达到一定的密实度；机器的行走是靠本身的动力，而不依赖混合料对机器的反作用力，因而行走较稳定。
The working principle of the vibrating roller sliver is that a high frequency and low amplitude vibrator is installed on the mold to make the cement concrete to a certain degree of compaction through the vibrator; the machine walking depends on its own power without relying on the reaction force of the mixture to the machine, so it is more stable.
各种路缘石滑模机的工作原理虽然有所不同，但其结构一般都由科斗、喂料器、成型模具、密实机构、升降系统及控制系统等组成。
Although the working principle of all kinds of slippery sliver is different, its structure is generally composed of the pipe, feeder, molding mold, dense mechanism, lifting system and control system.
