TST填充式伸缩缝

TST桥梁伸缩缝又叫沥青填充式桥梁伸缩缝它是无缝伸缩缝粘接料的一种，是七十年代由英国发展起来的一种桥梁伸缩缝技术。此工艺的基本作法是将接缝上面一窄条范围的桥面铺装层替换为一种高弹性的特殊沥青混合料。高弹性特种沥青与石料的混合物可以吸收由于温度和交通负荷作用产生的桥面板位移，而保证表层不会开裂损坏。无缝伸缩粘接料能够同时兼顾高温和低温、渗透和粘性这些对立的性能要求，不仅适用于温度单一地区，而且适用于温差较大的地区。
TST bridge expansion joint, also known as asphalt filLED bridge expansion joint, is a kind of seamless expansion joint bonding material and a bridge expansion joint technology developed from Britain in the 1970s. The basic method of this technology is to replace a narrow bridge deck pavement above the joint with a special asphalt mixture with high elasticity. The mixture of high elastic asphalt and stone can absorb the displacement of bridge deck caused by temperature and traffic load, and ensure that the surface will not crack and damage. Seamless expansion bonding material can take into account the opposing performance requirements of high and low temperature, permeability and viscosity at the same time. It is not only suitable for single temperature area, but also suitable for areas with large temperature difference.
TST无缝伸缩缝产品特点：
TST seamless expansion joint product characteristics:
TST无缝伸缩的弹性恢复力非常高：能适应不断重复的温度和荷载位移。
The elastic resilience of TST seamless expansion is very high: it can adapt to repeated temperature and load displacement.
低温柔性和高温稳定性都非常好：在-40℃时不会变脆，在80℃时不会流动。因此，能适用于中国所有气候区。
Both low temperature flexibility and high temperature stability are very good: it will not become brittle at - 40 ~C and will not flow at 80 ~C. Therefore, it can be applied to all climatic regions in China.
高温粘附性好：施工时可与现有路面牢固粘结，常温一点儿也不粘，冷却后又不会被粘带走。
Good adhesion at high temperature: construction can be firmly bonded with the existing road surface, normal temperature is not at all sticky, after cooling will not be sticky away.
施工方便、灵活：熟练的施工队伍（8-10人）每天可30延米GTF、TST伸缩缝，而且可在不阻断交通的情况下半幅施工。
Convenient and flexible construction: skilLED construction team (8-10 people) can reach 30 meters GTF, TST expansion joints per day, and can be constructed in half without blocking traffic.
开放交通迅速： 无缝伸缩缝粘接料安装后两个小时即可开放交通，若喷水加速冷却，一小时后即可开放交通。
Open traffic is fast: two hours after installation of seamless expansion joint adhesives, open traffic, if spraying water to accelerate cooling, open traffic in one hour.
使用寿命长：严格按照工艺要求安装的无缝伸缩缝粘接料，其寿命是一般改性沥青路面的两倍左右。
Long service life: Seamless expansion joint adhesives instalLED in strict accordance with process requirements, its service life is about twice that of general modified asphalt pavement.
舒适性非常好：无缝伸缩缝粘接料能充分吸收车辆振动冲击，车辆驶过舒适平稳。
Comfort is very good: seamless expansion joint adhesive can fully absorb the impact of vehicle vibration, vehicle ride comfortably and smoothly.
经济效益好：成本低廉。
Good economic benefit: low cost.
TST无缝伸缩缝安装注意事项：
Notes for installation of TST seamless expansion joint:
1.伸缩缝在安装前一旦碰撞变形，很难修复为合格产品，所以在安装的全过程中，一定要采取措施保护，严禁任何车辆通过。
1. once the expansion joint collides and deforms before installation, it is difficult to repair it as a qualified product. Therefore, in the whole process of installation, measures must be taken to protect it, and no vehicle is allowed to pass through.
2.安装伸缩缝要求严格，一定要精心操作。由于现场不易调整，所以成品检查一定要认真、仔细。不合格不可运至现场。
2. Installation of expansion joints is strictly required and must be carefully operated. Because the site is not easy to adjust, so the finished product inspection must be serious and careful. Unqualified can not be shipped to the scene.
3.伸缩缝安装前，要与设计图和现场核对位置、尺寸无误后，再稳放入预留槽。
3. Before installation of expansion joints, check the position and size with design drawings and site before placing them in the reserved slot steadily.
4.桥上各接缝处缝隙一定要用聚苯乙烯泡沫板塞严，防止浇注保护带混凝土时灌入，使缝失效。同时，也不可将装置内灌进混凝土，以免更换V形象胶带时受阻。
The joints on the 4. bridges must be tightly seaLED with polystyrene foam boards to prevent pouring into the concrete when the concrete is protected. At the same time, concrete can not be poured into the device, so as not to be blocked when replacing V image tape.
5.伸缩缝保护带混凝土浇筑后，前七日一定要及时洒水养护，以利强度增长和防止裂缝出现。
5. After concrete pouring of expansion joint protective belt, water must be sprinkLED and maintained in time for the first seven days in order to increase strength and prevent cracks from appearing.
