5、elding磨平顶面成活 polishing主要工序 main process不锈钢板样品 不锈钢板提前委托金属加工单位进行切割、钻孔、刨边、打磨加工，确保不锈钢板平整、光滑，无变形、毛刺、裂边、翘边等不良缺陷，并确保孔位正确。钻孔要打成坡口，以利送入焊条，坡面向上 an metal processing unit is entrusted to cut, drill,bevel and polish the stainless steel plates in advanceto ensure that they are glossy and smooth and freefrom such

6、defects as deformation, burr, edge crackand raised edge, and that the holes are in the rightplaces. the drill hole shall be drilled into beveled edgesto feed welding rods with its groove face upwards.不锈钢板加工锚脚加工processing of anchor legs设计锚脚为10光圆钢筋，长200mm，其最小净距40mm，共计319颗。为了保证顺利贯入不锈钢板，必须确保各锚脚竖直、间距精准。锚

7、脚间采用钢架固定，形成一个整体固定骨架，防止浇筑砼过程中使锚脚产生位移，同时将锚脚加长，以利于不锈钢板贯入时准确对位。加工好的骨架要进行预贯穿，确保各锚脚之间相对位置准确the designed anchor legs are made of 10 plain round bars with the length of 200mmand the minimum clearance of 40mm, 319 in total. the anchor legs shall be vertical andthe distance shall be accurate so as to insert t

8、he stainless steel plate successfully. steelframes are used to fix the anchor legs to form a whole fixed frame to prevent them fromdisplacing while pouring concrete. meanwhile, the anchor legs are extended to enablethe accurate alignment of the stainless steel plate. the processed frame shall be ins

9、ertedbeforehand to ensure the accuracy of relative locations of each anchor legs.设计锚脚为 10光圆钢筋，长200mm，其最小净距40mm，共计319颗。为了保证顺利将加工好的锚脚钢架运至施工现场就位处，在预先设置好的控制桩上拉十字线，用钢尺调整其平面位置，用水平仪调测其高程，准确后采用少量砼事先将骨架临时固定，再复测其平面位置和高程，无误后待砼固结。当砼具有一定强度后再进行一次预贯入，预贯入可以加工一块孔径和孔位与不锈钢板一致的模板进行。transport the processed anchor leg st

10、eel frame to specified location of the site; arrange across wire on the control piles set in advance; use a steel rule to adjust its plane position and alevel gauge to adjust and measure its elevation. use a small amount of concrete to fix the frametemporarily in advance after a cross wire is accura

11、tely set and then re-measure the plane positionand elevation. when the concrete is thickened to a certain strength, insert the frame into theconcrete again with a die with the same hole diameter and location of that of the stainless steelplate.固定不锈钢面板锚脚fixing of anchor legs for stainless steel plate

12、s主要是控制好砼高程，保证砼路面平整度，一切准确后，即贯入不锈钢板。贯入不锈钢板应在砼终凝前完成，这样可以利用不锈钢面板自重使不锈钢面板与砼结合紧密，确保了砼路面不会出现正误差。the most important thing is to control the elevation of the concrete to ensure theevenness of the concrete road. after all things are accurately done, insert the stainlesssteel plate. the stainless steel plate s

13、hall be inserted before the concrete coagulation,through which the stainless steel plate can closely integrate with the concrete relyingon its self-weight, preventing the occurrence of positive error.砼路面浇筑pouring of concrete pavement焊接工作在砼强度增长7天后进行。焊接时，先轻微点焊定位及打底，再行主焊缝施焊，最后封面焊缝施焊。为防止焊接产生的高温应力使不锈钢板变形

14、，焊接点位均采取梅花形间隔进行，不得顺序焊接。定位工作全部完成后，再行打底，打底工作全部完成后再进行主焊。主焊缝施焊不必一次填满焊缝，焊完一层，即进入下一焊点，待焊点基本冷确后再焊上一层。封面焊缝应适当高出板面。封面焊缝完成后，打磨表面成活。the welding shall be carried out after the strength of the concrete is increased for 7 days. duringthe welding, spot welding for fixing positions and backing welding shall be carr

15、ied out slightly beforewelding the main weld seam and the cover weld seam. the welding point positions shall be of quincunxtype, rather than in sequence, to prevent the stainless steel plate from deformation caused by the hightemperature stress during the welding. the backing welding shall be carrie

16、d out after the positioning,and then the main weld seam. there is no need to weld the whole weld seam once while welding it.another welding spot can be welded after one layer is finished. an extra layer can be welded afterthe welding spot is cooled. the cover weld seam shall be higher than the plate

17、 surface appropriately.after welding the cover weld seam, the surface shall be polished.焊接 welding鹅卵石路长10m，宽3米。如图cobble road is 10 m long, width of 3 meters.as shown in figure（二）鹅卵石路面 cobble road鹅卵石样品sample of cobble施工工艺 procedure首先浇筑下层混凝土再铺设m10水泥砂浆，安装固定卵石，凸出高度符合设计要求30-50mm。卵石人工栽植。pour concrete befo

19、 withthe steps composed of 8 bevels.施工流程 procedure台阶路面分两个阶段施工：第一阶段施工c30底层路面，可以上人即进入第二阶段作台阶面层。第二阶段分两次成型：第一次1、3、5、7，第二次2、4、6、8。混凝土表面采用铝合金枋刮平，表面收光。垂直面光面覆膜板立模。for the step road, there are two construction stages: the first stage is to lay c30 basepavement. the second stage can be started if people can w

20、alk on the base pavement.the second stage can be divided into two times to shape: the first time 1, 3, 5, 7 and thesecond time 2, 4, 6, 8. the concrete surface shall be smoothed by an aluminum alloysquare-column and the surface shall be polished. the film face plywood on the verticalsurface serves a

21、s a die.覆膜模板样品(四)扭曲路面施工 crooked road 扭曲路面全长13米，宽3米，为c30砼结构，由9个高出路面15cm的扭曲块组成，扭曲块呈错位两排布置。the 13m long and 3m wide crooked road is of c30 concrete structure composedof 9 crooked blocks 15 cm higher than the pavement and laid in two rows in a mismatchmanner.施工难点 construction difficulties 每一个扭曲块顶面有6个斜面，

22、形状复杂。扭曲块斜面多，斜度大，一次现浇方案无法保证这种质量要求。所以本路段的施工难点也在于如何保证扭曲块的成型质量。there are 6 bevels with complex shapes on the top of each crookedblock. the crooked block has so many bevels and high inclination;therefore, the cast-in-place program cant meet this qualityrequirement. the construction difficulty in this sec

23、tion is how to ensurethe forming quality of crooked blocks.施工流程 procedure施工分两步，第一步施工扭曲块的突出台体部分，按照设计轮廓加工出台体的模板，台体部分留出预埋的连接筋。第二步施工扭曲之间的平路面，按照常规工艺施工。there are two construction stages: firstly, for the protruded part of the crookedblock, a die shall be processed as per the designed frame and an embedded
