A Measuring Nail Shooting Fixed Point Mechanism Aiming at Switching Softness and Hardness of Foundation Pit

Abstract

The invention discloses a nail-shooting fixed-point mechanism aimed at switching the softness and hardness of a foundation pit. Inside, the prism connecting frame is fixed above the support rod, the air bubble aligner is connected to the center of the support rod, and the nailing point switching mechanism is equipped with a nailing switching mechanism, a colored rope surrounding connection mechanism, and a pulling colored rope cutting mechanism, with beneficial effects: A special nailing fixed point switching mechanism is set up for the fixed point of the foundation pit. Different nails can be selected through different sites. When the site is relatively soft and subsidence, it is necessary to use the big head nails to fix the point to reduce the flooding of the nails. Phenomenon, after the fixed point is completed, the positioned points can be connected, and when one side is covered, the corresponding relative point can be found through the other three points.

Description

technical field [0001] The invention relates to a nail-shooting and fixed-point mechanism for measuring the softness and hardness of foundation pits, which belongs to the field of measurement. Background technique [0002] Measuring equipment is a kind of equipment for detection and data processing, which involves various aspects, including a kind of measuring equipment for construction engineering. Theodolite is the most important equipment for site measurement. It is composed of theodolite, tripod and prism. Through professional measurement The personnel go to stake out to realize the stake out and position the column. The shortcomings of the current technology are as follows: [0003] When setting out the platform, the staff needs to set up the theodolite at a high place for measurement, and another person will hold the prism to the foundation pit at the lower position to carry out the stakeout, and locate the point according to the measurement of theodolite and the commu...

Problems solved by technology

[0003] When setting out the platform, the staff needs to set up the theodolite at a high place for measurement, and another person will hold the prism to the foundation pit at the lower place to carry out the stakeout, and locate the point according to the measurement of theodolite and the communication between the two For the follow-up staff to carry out construction, the fixed point is usually to position the nail on the ground in the existing technical equipment, but the hardness of the ground is uncertain and the nail does not have certain compression resistance, which will cause the surrounding soft soil to break out. The subsidence will cover the nails and knock the nails away when the workers are unloading the bricks, making it necessary to re-measure and fix the points
