Hole channel punching construction process for optimizing and reinforcing cross-sea bridge
The invention discloses a hole channel punching construction technology for optimizing and reinforcing a cross-sea bridge. The method comprises the steps that the prestress condition of a longitudinal beam with a first preset number of standby holes is detected; formulating a construction scheme suitable for the prestress condition; and according to the construction scheme, drilling construction is conducted on the longitudinal beam, and a prestressed duct is obtained. The prestress condition of the longitudinal beam of the bridge tower is determined in combination with the actual condition of the construction site, the corresponding construction scheme is formulated according to the prestress condition, drilling construction is conducted on the longitudinal beam according to the construction scheme, the prestress hole channel is obtained, and the situation that in the drilling construction process of the longitudinal beam, the construction cost is reduced is avoided. And whether the drilled hole channel affects the prestress condition of the longitudinal beam or not is continuously detected, so that the construction efficiency of the hole channel punching construction process is improved.
本申请公开了一种跨海大桥优化补强用孔道打孔施工工艺，该方法包括步骤：检测存在第一预设数量的备用孔的纵梁的预应力情况；制定适用于所述预应力情况的施工方案；根据所述施工方案，对所述纵梁进行钻孔施工，得到预应力孔道。本申请实现了结合施工现场的实际情况，确定桥塔的纵梁的预应力情况，并根据预应力情况制定相应的施工方案，从而根据施工方案对纵梁进行钻孔施工，得到预应力孔道，避免在对纵梁进行钻孔施工过程中，不断检测钻取的孔道是否对纵梁的预应力情况是否存在影响，从而提高孔道打孔施工工艺的施工效率。
