Tunnel advanced horizontal reinforced jet grouting pile supporting structure and construction method
The invention relates to the technical field of tunnel supporting, in particular to a tunnel advanced horizontal reinforcement jet grouting pile supporting structure and a construction method. The tunnel advanced horizontal reinforcement jet grouting pile supporting structure is a combination of reinforcement cages and jet grouting piles, each reinforcement cage comprises a plurality of longitudinal main reinforcements and a plurality of fixing rings, the four longitudinal main reinforcements are evenly welded to the ring face of each fixing ring at equal intervals, the fixing rings are sequentially welded, and the main reinforcements on the fixing rings are correspondingly welded one by one; and the reinforcement cages are sequentially inserted into the jet grouting piles to form the tunnel advanced horizontal reinforcement jet grouting pile supporting structure. The support adopts a reinforcement cage structure, and the fixing rings and the main reinforcements are used for equidistant constraint to form a reinforcement bundle with higher bending resistance, so that the pre-reinforcement area is increased, the tension fracture damage of a stress surface to a side pile body is reduced, the bending resistance of the pile body is further enhanced, and a more effective and safer advanced support system is formed.
本发明涉及隧道支护技术领域，具体为一种隧道超前水平加筋旋喷桩支护结构及施工方法；所述隧道超前水平加筋旋喷桩支护结构为钢筋笼和旋喷桩的组合，每个钢筋笼包括若干纵向主筋和若干固定环，每一个固定环环面上均匀等距焊接有四个纵向主筋，若干固定环依次焊接，且若干固定环上的主筋均逐一对应焊接；所述钢筋笼依次插入旋喷桩中，形成隧道超前水平加筋旋喷桩支护结构。本支护采用钢筋笼结构，利用固定环和主筋进行等距约束，以形成抗弯性能较大的钢筋束，在增大预加固面积的同时，减小受力面对侧桩体的拉裂破坏，进一步增强桩体抗弯性能，以此形成更加有效、更加安全的超前支护体系。
