Corrosion-resistant and fatigue-resistant chilled casting anchorage device for ultra-high-strength ultra-long stay cable
The invention relates to an ultra-high-strength ultra-long stay cable corrosion-resistant fatigue cold casting anchorage device which comprises an anchor cup and a connecting cylinder, the connectingcylinder is arranged at the front end of the anchor cup and coaxially communicated with the anchor cup, a stay cable penetrates through the connecting cylinder and is anchored in the anchor cup, and the anchor cup is provided with an anchoring cavity. The steel wire bundle of the stay cable is dispersed in a conical shape from front to back and anchored in the anchoring cavity through the anchoring filler, and the anchoring cavity comprises more than two conical anchoring cavities which are continuously arranged. And the taper of the inner cavities of the conical anchoring cavities is the same. The plurality of conical anchoring cavities at least comprise a main conical anchoring cavity with the length of L1 and the inner cavity taper of beta, the plurality of conical anchoring cavities atleast comprise a main conical anchoring cavity with the length of L1 and the inner cavity taper of beta, and the main conical anchoring cavity independently meets the anchoring strength of the stay cable.
本发明涉及一种超高强度超长斜拉索耐腐蚀疲劳冷铸锚具，包括锚杯和连接筒，连接筒设置在锚杯前端、二者同轴贯通，斜拉索穿过连接筒并锚固在锚杯内，锚杯具有锚固腔，斜拉索的钢丝束从前向后呈锥形散开通过锚固填料锚固在锚固腔内，锚固腔包括两个以上连续设置的锥形锚固腔。多个锥形锚固腔的内腔锥度相同。多个锥形锚固腔中至少包括一个长度为L1、内腔锥度为β的主锥形锚固腔，多个所述锥形锚固腔中至少包括一个长度为L1、内腔锥度为β的主锥形锚固腔，该主锥形锚固腔单独满足对斜拉索的锚固强度。
