Blasting silt squeezing construction method for deep soft foundation of fishing port breakwater
The invention discloses a blasting silt squeezing construction method for a deep soft foundation of a fishing port breakwater. The blasting silt squeezing construction method comprises the following stages of a construction preparation stage, an implementation stage and a verification stage. The construction preparation stage comprises the following steps of blasting grade division, stone mining specification control, carrying out construction parameter design, blasting explosive quantity calculation and blasting network design; the implementation stage comprises the following steps of carrying out measurement control, breakwater body throwing and filling, breakwater head blasting and filling, breakwater body circulating throwing and filling, lateral blasting and filling, breakwater side dredging and block stone supplementing and throwing; the verification stage comprises the steps of verifying the plane position and the bottom falling depth, verifying by adopting a drilling exploration method and a volume balance method, and carrying out settlement displacement observation auxiliary verification. According to the method, replacement of mudstone below the mud surface of the breakwater core stone is completed through blasting silt squeeze, the thickest depth of replaced silt reaches 28 m, explosive distribution is conducted on a land through an explosive distributor to completeblasting silt squeeze, complete land operation can be achieved, various technical indexes are easy to control, the quality is controllable, the construction efficiency is high, and influences of general natural factors are small.
本发明公开了一种渔港防波堤深厚软基的爆破挤淤施工方法，包括以下阶段：施工准备阶段、实施阶段和验证阶段。施工准备阶段包括以下步骤：爆破等级划分、石料开采规格控制、施工参数设计、爆破药量的计算、爆破网络设计。实施阶段包括以下步骤：测量控制、堤身抛填、堤头爆填、堤身循环抛填、侧向爆填以及堤侧挖泥与补抛块石。验证阶段包括验证平面位置和落底深度，采用钻孔探摸法和体积平衡法进行验证，加以沉降位移观测辅助验证。本发明采用爆破挤淤完成堤心石泥面以下泥石置换，置换淤泥最厚深度达28米，采用布药机在陆上进行布药完成爆破挤淤，可完全陆上操作，各项技术指标容易控制，质量可控，施工效率高、受一般自然因素影响小。
