Deepwater bedrock non-explosion excavation construction method
The invention relates to the field of underwater excavation, in particular to a deepwater bedrock non-explosion excavation construction method which comprises the following steps: S1, positioning a construction position, S2, driving a drilling ship to the construction position, drilling plum blossom holes at the interval of 3.0 m * 3.0 m with the drilling depth of 1.0 m/layer, and drilling from upstream to downstream during drilling; s3, a grab bucket of the grab dredger is replaced with a rock drilling rod, after the rock drilling rod is lifted to a certain height through a loaded crane, the rock drilling rod is loosened, and rock is smashed downwards; s4, a rock drilling rod on the grab dredger is replaced with a grab bucket to excavate and grab broken stones, and the grab bucket filled with the broken stones is lifted to a mud conveying ship through a crane; s5, the excavation elevation is measured according to the excavation layer number and the excavation amount; s5a, if the designed elevation is not reached, the step S3 is carried out; and S5b, the designed elevation is achieved, and foundation pit construction is completed. The non-blasting excavation function is achieved, and the problems that a traditional deep water foundation blasting excavation method is large in construction difficulty, and safety and excavation quality are difficult to control are solved.
本发明涉及水下挖方领域，具体是涉及深水基岩非爆开挖施工工法，包括以下步骤：S1：定位施工位置，S2：将钻孔船行驶至施工位置，以3.0m×3.0m间距钻梅花孔，钻孔深度1.0m/每层，钻孔时从上游向下游钻进；S3：将抓斗式挖泥船的抓斗更换为凿岩棒，利用装载的吊机提升凿岩棒至一定高度后，松开凿岩棒，下砸破碎岩石；S4：将抓斗式挖泥船上的凿岩棒更换为抓斗，来挖掘和抓取碎石，并通过吊机将装满碎石的抓斗提升至运泥船上；S5：根据开挖层数和开挖放量测量开挖标高；S5a：未达到设计标高，进行S3；S5b：达到设计标高，完成基坑施工。本发明实现了非爆开挖的功能，解决了传统深水基础爆破开挖方法施工难度大、安全性及开挖质量难以控制的问题。
