Real-time monitoring method for offshore gravel pile construction
The invention discloses a real-time monitoring method for offshore gravel pile construction, which is based on a PLC (Programmable Logic Controller) monitoring system, and the PLC monitoring system comprises a GPS (Global Positioning System), a radar range finder, a weighing sensor, an encoder and a main controller. The invention discloses a real-time monitoring method for offshore gravel pile construction. The real-time monitoring method comprises the following steps that firstly, various parameters of gravel piles are input into a display screen of a main controller; secondly, when the pile pipe is vibrated into a soil layer by a certain depth, gravel materials of the two measuring hoppers are added into the pile pipe; thirdly, the pile pipe continues to be vibrated to the designed bottom elevation in the pressure holding state; step 4, carrying out end part treatment; fifthly, the pile pipe is lifted, when the height of the gravel materials in the pile pipe is smaller than 3-5 m, lifting of the pile pipe is stopped immediately, the remaining gravel materials are added into the pile pipe, and then the pile pipe is lifted again; and sixthly, the pile pipe bottom elevation is compared with the designed pile top elevation of the gravel pile, and whether the pile pipe needs to be driven back or not is judged. The pile forming quality of the gravel pile can be effectively controlled.
本发明公开了一种用于海上碎石桩施工的实时监控方法，基于PLC监控系统，该PLC监控系统包括GPS定位系统、雷达测距仪、称重传感器、编码器和主控制器。本发明用于海上碎石桩施工的实时监控方法，包括以下步骤一，先在主控制器的显示屏中输入碎石桩的各项参数；步骤二，将桩管振设入土层一定深度时，向桩管内投加两计量斗的碎石料；步骤三，在持压状态下继续振设桩管至设计底标高；步骤四，进行端部处理；步骤五，提升桩管，当桩管内碎石料的高度小于3～5m，立即停止提升桩管并向桩管内加完剩余的碎石料，然后再提升桩管；步骤六，将桩管底标高与碎石桩的设计桩顶标高进行对比，判断是否要回打桩管。本发明能有效控制碎石桩的成桩质量。
