What is the process of drilling holes with rhinestones?

Rhinestone Drilling and Cutting Construction Plan 1 Project Overview According to the design change requirements, the upper opening of the original elevator door is now raised upward to meet the elevator installation requirements. The machine room is opened according to the installation requirements, so protective static removal with rhinestones is used. 2. Basis for compilation 1. "Technical Regulations for Reinforcement of Concrete Structures" (CECS25: 90) 2. "Code for Design of Concrete Structures" (GB50010-2002) ； 3. "Technical Regulations for Temporary Electricity Safety at Construction Sites" (JGJ46-88) ； 4. "Technical Regulations for Safety in the Use of Construction Machinery" (JGJ33-86). 3. Specific construction process and construction methods 1. Construction process flow: Set up a construction cordon around the construction site and protect the finished product ------------- Mark the door opening cutting position line ------ Rhinestone removal ----------- Cut off block processing ------------- Clean the working surface 2. Specific construction technology and methods 1. Set up a construction cordon around the construction site. Since the aluminum alloy door frame on the inside of the elevator has been installed, a slope must be set up under the rhinestone construction surface with bamboo plywood before construction to prevent falling objects from damaging the aluminum alloy door frame. 2. Mark the location to be cut on the working surface according to the installation requirements. 3. Rhinestone construction: (1) The specific process of rhinestone cutting: Use an electric drill to drill the fixing bolt hole ↓ Put in the expansion bolt ↓ Install the fixing screw ↓ Fix the rhinestone ↓ Start cutting during the construction process. According to the damage to the original structure caused by drilling holes in the concrete, use a drill bit with a diameter of 102 mm. It is the safest and most economical. 4. Removal block processing Since the working surface is two meters above the ground and 300-400mm behind the wall, the resection block must not be larger than 50 kg during the resection process, so the resection block must not be larger than 40cm long. After resection, it is removed manually and turned to the ground. 4. Construction deployment 1. Project objectives: Party A requires a tight construction schedule. And strictly follow the ISO9002 standard procedures, grasp the entire construction process, and create first-class standards in the entire construction management, process quality, construction period and other economic and technical indicators. 2. Quality objectives: Reinforcement construction ensures that the construction drawing requirements are met, "Concrete Structure Reinforcement Technology (CECS25:90)" 3. Construction period objectives: Reasonable overall arrangements to ensure that Party A's construction needs the construction period 4. On-site management objectives: Strengthen the scientific management of construction sites, create first-class construction sites, resolutely eliminate all major safety accidents, implement relevant regulations on construction site safety and civilized construction, and strive to create a safe and civilized construction site. 5. Task division: Our company is responsible for the reinforcement and sub-project construction work of this project. 6. Construction arrangements: ： This project plans to divide the working surface according to the actual space conditions and different construction techniques, and organize the construction in sections based on the process requirements.: 5. Construction safety and precautions 1. When working at heights, you must wear safety belts and non-slip shoes. 2. During the operation, you must obey the safety supervision of the safety officer and prohibit illegal operations. You must provide horizontal protection on the working surface. 3. Operators should wear work clothes, protective masks and gloves. 4. The workplace should be equipped with necessary fire extinguishers for rescue purposes. 5. Quality pre-control: (1) Establish a strict quality pre-control and inspection and acceptance system. (2) Establish a system of self-inspection, mutual inspection, and handover inspection, and the information forms must be complete. (3) Establish a strict material inspection system. Unqualified materials are strictly prohibited from entry. (4) Make technical briefings, and the construction team and technicians shall be briefed by the project technical leader ； Operators of each process shall be briefed by each team leader, and the content of technical briefings must include quality standards and operating methods and be targeted. Technical disclosure requires written signature procedures. (5) Establish a detailed construction quality reward and penalty system and implement it by designated personnel from the project department.
