TST橋梁伸縮縫

TST bridge expansion joint

TST橋梁伸縮縫又叫瀝青填充式橋梁伸縮縫它是無縫伸縮縫粘接料的一種，此工藝的基本作法是將接縫上面一窄條范圍的橋面鋪裝層替換為一種高彈性的特殊瀝青混合料。高彈性特種瀝青與石料的混合物可以吸收由于溫度和交通負荷作用產(chǎn)生的橋面板位移，而保證表層不會開裂損壞。無縫伸縮粘接料能夠同時兼顧高溫和低溫、滲透和粘性這些對立的性能要求，不僅適用于溫度單一地區(qū)，而且適用于溫差較大的地區(qū)。

TST bridge expansion joint is also called asphalt filled bridge expansion joint. It is a kind of seamless expansion joint adhesive material. The basic method of this technology is to replace a narrow strip of bridge deck pavement on the upper part of the joint to a high elastic special asphalt mixture. The mixture of high elastic special asphalt and stone can absorb the displacement of bridge deck caused by temperature and traffic load， and ensure that the surface will not crack. Seamless stretch adhesive material can take into account both the high temperature and low temperature， osmosis and sticky performance requirements， not only for single temperature area， but also for large areas with large temperature difference.

TST無縫伸縮縫產(chǎn)品特點

Product features of TST seamless expansion joint

TST無縫伸縮的彈性恢復力非常高：能適應不斷重復的溫度和荷載位移。

低溫柔性和高溫穩(wěn)定性都非常好：在-40時不會變脆，在80時不會流動。因此，能適用于中國所有氣候區(qū)。

高溫粘附性好：施工時可與現(xiàn)有路面牢固粘結，常溫一點兒也不粘，冷卻后又不會被粘帶走。

施工方便、靈活：熟練的施工隊伍（8-10人）每天可30延米GTF、TST伸縮縫，而且可在不阻斷交通的情況下半幅施工。

開放交通迅速： 無縫伸縮縫粘接料安裝后兩個小時即可開放交通，若噴水加速冷卻，一小時后即可開放交通。

使用壽命長：嚴格按照工藝要求安裝的無縫伸縮縫粘接料，其壽命是一般改性瀝青路面的兩倍左右。

舒適性非常好：無縫伸縮縫粘接料能充分吸收車輛振動沖擊，車輛駛過舒適平穩(wěn)。

經(jīng)濟效益好：成本低廉。

TST seamless resilient resilience is very high able to adapt to constant temperature and load displacement. Low temperature flexibility and high temperature stability are very good it will not become brittle at -40 C， and will not flow at 80. Therefore， it can be applied to all climate zones in China. High temperature adhesion good construction can be firmly bonded with the existing pavement， the room temperature is not sticky at all， and will not be taken away after cooling. Convenient and flexible construction， skilled construction team （8-10）， 30 meter GTF TST expansion joint every day， and can not block the traffic under the condition of half construction. The open traffic is rapid the seamless expansion joint will open two hours after the installation of the joint. If the water is accelerated and cooling， the traffic can be opened in one hour. Long service life the seamless joint adhesive bonded by the seamless expansion joint according to the technical requirements is about two times as long as the general modified asphalt pavement. The comfortableness is very good the seamless joint joint can fully absorb the vibration and shock of the vehicle， and the vehicle is comfortable and smooth. The economic benefit is good the cost is low.

TST無縫伸縮縫安裝注意事項

TST seamless expansion joint installation attention

1.伸縮縫在安裝前一旦碰撞變形，很難修復為合格產(chǎn)品，所以在安裝的全過程中，一定要采取措施保護，嚴禁任何車輛通過。

1.， once the expansion joint is collided and deformed before installation， it is difficult to repair the qualified product. Therefore， in the whole process of installation， we must take measures to protect and strictly prohibit any vehicle passing.

2.安裝伸縮縫要求嚴格，一定要精心操作。由于現(xiàn)場不易調整，所以成品檢查一定要認真、仔細。不合格不可運至現(xiàn)場。

2. installation expansion joint requires strict， and must be carefully operated. Because the site is not easy to adjust， so the finished product inspection must be careful and careful. Unqualified can not be shipped to the scene.

3.伸縮縫安裝前，要與設計圖和現(xiàn)場核對位置、尺寸無誤后，再穩(wěn)放入預留槽。

3. before the installation of the expansion joint， to check the location and size of the design and site， and then put it in the reserved slot.

4.橋上各接縫處縫隙一定要用聚苯乙烯泡沫板塞嚴，防止?jié)沧⒈Ｗo帶混凝土時灌入，使縫失效。同時，也不可將裝置內灌進混凝土，以免更換V形象膠帶時受阻。

The gap between the joints on the 4. bridge must be slug with polystyrene foam plate to prevent pouring into the protective belt concrete and failure of the seam. At the same time， the device can not be poured into the concrete in order to avoid the replacement of the V image tape.

5.伸縮縫保護帶混凝土澆筑后，前七日一定要及時灑水養(yǎng)護，以利強度增長和防止裂縫出現(xiàn)

After 5. expansion joint protection belt concrete pouring， the first seven days must be timely sprinkler maintenance， in order to increase the strength and prevent cracks
