(1) 聚氨酯塑胶材料的施工过程中最怕水、胶浆在初步固化前碰到一滴水珠就会产生一个大的气泡,因此施工人员在高温条件下作业要准备毛巾擦汗。铺胶面时一定掌握天气情况并要做好防止突降阵雨的应急措施。铺胶时间要避开早晨大气中和地面湿度较大的时候,即使在天气晴朗的正常工作日,一般最好在上午九点以后正式铺设塑胶跑道铺设。
(1) the construction process of polyurethane plastic materials in most afraid of water, glue in the initial curing met a drop of water before it will generate a large bubble, so the construction personnel working to prepare a towel Cahan under high temperature conditions. Spread glue surface must grasp the weather and to do a good job of emergency measures to prevent sudden showers. PU adhesive time to avoid the morning air time and ground humidity, even in the normal working day, weather is sunny, generally the best at nine in the morning after the formal laying plastic track laying.
(2) 胶面的实铺厚度是指从胶底至表层胶粒的中心,一般从两方面控制。首先通过立模进行厚度尺寸的预检,对基层局部高出的地方进行修砍或锤击进行夯低。如果高出不多,可采用平刮尺上加卡具离模刮浆来保证厚度,第11届亚运会北郊比赛场塑胶跑道主赛区为保证厚度,误差控制为正差,故平均厚度在14MM以上。
(2) the glue surface shop thickness is from the bottom to the surface of colloidal particle center, usually from two aspects of control. First through the mould thickness size Yujian, on the base of local high place for repairing cut or hammer for ramming low. If not, can adopt flat wiper ruler Guajiang from mould add fixture to ensure the thickness, the Eleventh Asian Games in Beijiao stadium plastic runway main division to ensure the thickness, error control is poor, so average thickness in 14MM above.
(3)塑胶跑道雨后不积水的施工经验:A、为保证平整度,铺设跨度尽量大,主跑道上跨度为3.66米(三条道同时摊铺),非赛区跨度大于4米。B、一般在南北半圆雨后肯定有局部积水现象,特别是跳高区半圆更为严重。为保证坡度,最好采用“龟背式”施工法,以利于排水。
(3) the construction experience of plastic runway after the rain is not water: A, to ensure the smoothness, the laying of large span, main runway for the span of 3.66 meters (three road and paving), non division span more than 4 meters. B, generally in the North-South semicircle after the rain must have local water phenomenon, especially the high jump area semicircle is more serious. To ensure the slope, the best use of "turtle" construction method, in order to facilitate drainage.
(4) 防止胶面铺筑后局部发生起泡脱壳,对于基层密实度要严格控制,防止沥青基础层自身嵌挤不实,脱壳脱层,致使粘结力差,表面气化,胶面被拉断。基层密实度不够的地方,可以采用钻头打孔,灌胶(橡胶钉)的方法进行加固。
(4) to prevent the rubber surface blister shelling occurred after local done.the, for grassroots shall strictly control the density, prevent the asphalt base layer itself squeezed untrue, shed layer, resulting in poor adhesion, surface gasification, the rubber surface is broken. Grassroots Construetion insufficient place, can be used to drill, glue (rubber nail) method for reinforcement.
(5) 为保证平整度、坡度,模条钉好后,用水平仪进行模拟校正,基层个别高的地方,先加以整平,个别低的地方,用胶填平。
(5) to ensure the smoothness, slope, die after the nail, level of analog correction, grassroots individual high place, first to leveling, individual low places, fill with glue.
(6) 被柴油污染和腐蚀的基础部位坚决挖掉,用胶填平。
(6) by diesel pollution and corrosion of basic parts resolutely out, fill with glue.
