Combined temporary cofferdam for crossing river channel and construction method of combined temporary cofferdam
The invention belongs to the technical field of cofferdam construction, and particularly relates to a combined temporary cofferdam for crossing a river channel and a construction method of the combined temporary cofferdam. The combined temporary cofferdam comprises a temporary cofferdam with a square cross section, the two ends of the temporary cofferdam correspond to the two banks of the river channel, and two inclined struts are arranged at the right-angle position of the temporary cofferdam; a square steel enclosing purlin is arranged on the inner side of the temporary cofferdam, a straight support is arranged in the middle of the square steel enclosing purlin and is parallel to the width direction of the square steel enclosing purlin, the temporary cofferdam is double-row cofferdams, each row of cofferdams are the same in structure, the two ends of each row of cofferdams are timber pile type cofferdams, and the middle of each row of cofferdams is a steel sheet pile type cofferdam; corresponding joints of the timber pile type cofferdams and the steel sheet pile type cofferdam are connected by welding seamless steel pipes and Z-shaped steel sheet piles; and a timber pile enclosing purlin is arranged on one side of the upper part of each row of timber pile type cofferdams correspondingly, and more than two opposite-pulling steel bars are bundled between a pair of timber pile enclosing purlins on the two rows of timber pile type cofferdams. Therefore, the temporary cofferdam is easy and convenient to construct, good in waterproof and anti-seepage performance and high in water flow impact resistance.
本发明属于围堰施工的技术领域，特别涉及一种用于跨河道的组合式临时围堰及其施工方法。包括横截面为方形的临时围堰，临时围堰的两端对应河道两岸，临时围堰的直角处均设有两道斜撑；临时围堰的内侧设有方形钢围檩，方形钢围檩的中部设有直撑，直撑平行于方形钢围檩的宽度方向布置，临时围堰为双排围堰，每排围堰结构相同，每排围堰的两端部为木桩式围堰、中部为钢板桩式围堰；木桩式围堰和钢板桩式围堰的对应结合处通过无缝钢管和Z型钢板桩焊接进行连接；对应每排所述木桩式围堰的上部一侧设有木桩围檩，且两排木桩式围堰上的一对木桩围檩之间捆扎两道以上的对拉钢筋。因此本发明的临时围堰施工简便，防水抗渗性能较好，抗水流冲击能力强。
