Circuit tower-foundation flow-style mechanical construction method

Abstract

Provided is a circuit tower-foundation flow-style mechanical construction method. The method includes the follow stepsthat 1, temporary roads are constructed; 2, early-stage preparation of construction is made; 3, arotary drilling rig conducts pore forming; 4, a steel reinforcement cage conducts industrialized processing and installation; 5, commercial concrete is used for pouring; 6, mechanical equipment is maintained; according to the circuit tower-foundation flow-style mechanical construction method, an operation mode whereparallel operation is combined with modularizedconnection is adopted, and the purposes of mechanical construction and flow-style operation in the overall process of the circuit tower foundation are achieved; fully mechanical constructionis adopted, and the temporary power input and the workload of manual operation are reduced;machines replace manpower to complete the lifting and lowering of the rotary drilling rig and other high-risk construction processes, dynamic risk values are reduced, and security risks are reduced; besides, construction sites are clean and tidy, and environmental pollution is less; meanwhile, the vibration of the rotary drilling rig is slight, the noise is low, so that the rotary drilling rig does not cause noise pollution to environment.

Description

technical field [0001] The invention relates to the field of foundation construction of overhead power transmission lines, in particular to a flow-type mechanical construction method for line tower foundations. Background technique [0002] At present, during the foundation construction of transmission lines, the common operation method is to use rotary drilling rigs or submersible drilling rigs to drill holes, weld steel bars on site, manually hang and place reinforcement cages, and use self-mixing concrete for manual pouring. This operation method has the advantages of The following disadvantages: 1. The drilling efficiency of the rotary drilling rig is low, the self-mixing concrete requires a large amount of labor, the pouring efficiency is low, and the serial operation method is adopted. The previous process is not completed, and the next process cannot be carried out. Without the frame, the drilling rig cannot be transferred to the construction site, resulting in low ef...

[0002] At present, during the foundation construction of transmission lines, the common operation method is to use rotary drilling rigs or submersible drilling rigs to drill holes, weld steel bars on site, manually hang and place reinforcement cages, and use self-mixing concrete for manual pouring. This operation method has the advantages of The following disadvantages: 1. The drilling efficiency of the rotary drilling rig is low, the self-mixing concrete requires a large amount of labor, the pouring efficiency is low, and the serial operation method is adopted. The previous process is not completed, and the next process cannot be carried out. frame, the drilling rig cannot be transferred to the construction site, resulting in low efficiency of the overall foundation construction and a large amount of labor

2. On-site welding needs to invest in temporary electrical devices, and the safety risk of manual lifting of the steel cage is relatively high

3. The quality of the hole formed by the rotary drilling rig is poor, and it is prone to eccentricity and hole collapse, and the verticality of the pile cannot be guaranteed. It is difficult to ensure the quality of the concrete pouring by mixing and pouring on site, resulting in poor quality of the overall foundation pile

4. The traditional line foundation construction method requires a lot of labor input. With the increasing labor cost, the economic benefit is poor
