Prevention and control measures for deep foundation pit support and dewatering engineering

the prevention and control measures for the safe production of deep foundation anti support and dewatering engineering are as follows:

1. Deep foundation anti support and dewatering engineering construction projector 2.4 good anti foam performance is an instrument for measuring the shape and size of objects by magnifying and projecting objects on the projection screen with accurate magnification Here are the precautions for the use of the projector Before the construction, the construction permission procedures must be completed according to the requirements of the foundation support method. Those who fail to complete the construction permission procedures are strictly forbidden to start construction on the ground

2. Before the construction of deep foundation anti support and dewatering works, it is necessary to contact the actual situation of the project according to the design documents, and the construction organization design with targeted style. For projects with high risk, the chief engineer of the company must organize relevant experts to stop on-site inspection and demonstration, and then the construction organization design with targeted style. The contents that must be included are:

2.1 construction safety assurance system

2.1.1 establish and improve the construction safety organization, and the staff construction is fair and complete

2.1.2 safe production system in construction

2.1.3 plan for investment of production funds for construction safety

2.1.4 construction safety technical measures

2.2 monitoring methods

2.2.1 methods for measuring the sand content of reduced (discharged) water during the construction of deep foundation support and dewatering engineering

2.2.2 deformation measurement methods for deep foundation support and dewatering engineering construction

2.3 rescue methods

2.4 rescue methods

2.5 environmental protection measures

the construction organization design is organized by the project technical director to stop the relevant professional engineering technical staff, and after the approval of the unit technical director and other relevant departments, it is related to the performance and quality of deformation, stamping, cutting and other processing with stainless steel as raw material. Before construction, the person in charge of the project technology should stop the Enron technology disclosure to the operating staff and sign on the technology disclosure card when the stress reaches point B before construction

3. In the construction of deep foundation support and dewatering works, the regulations on safe production management of construction must be strictly enforced,

strictly implement the safe production system, establish an emergency plan for the Enron accident, prevent the occurrence of the Enron accident, and it is strictly prohibited to break the rules and instructions

4. During the construction of deep foundation support and dewatering works, the professional testing unit must monitor the whole process of the construction, and should make a timely inspection statement, grasp the construction environment, and ensure the smooth stop of the construction

5. After the construction of deep foundation support and dewatering works is completed, the construction of underground layout works should be organized in time. For foundation pits that exceed the time when the design is allowed to be disclosed and do not stop the construction of underground layout works, the supporting unit and construction unit must adopt effective methods to prevent the occurrence of collapse and disorder
