Method for embedding measurement centering mark

Abstract

The invention relates to a method for embedding a measurement centering mark, which comprises the steps of reserving an embedding medium hole (5) in an embedding measurement mark medium (6) or the protecting wall top. The method is characterized by also comprising the following steps of: penetrating through a plummet wire (2) in a hoisting hole (4) where the measurement mark is embedded; hoisting the plummet wire (2) together with a measurement mark (3) into the embedding medium hole (5) and enabling the top surface of the measurement mark (3) to be slightly higher than a hole opening; slowly injecting a grouting material into the embedding medium hole (5) and enabling the top surface of the grouting material to be slightly lower than the hole; slowly lowering the plummet wire (2) and the measurement mark (3) till the top of the mark of the measurement mark (3) is parallel and level to the embedding medium hole (5); when the grouting material is slightly extruded, fixing the plummet wire (2) and enabling the top surface of the measurement mark (3) to be automatically flatly placed under the hoisting action of the plummet wire (2) on the measurement mark (3) in the liquid grouting material. The invention has the characteristics of high embedding precision, simple and convenient operation and low cost.

Description

Technical field: [0001] The invention relates to a method for anchoring and embedding an embedded part. It is suitable for the embedding of precision engineering measurement marks, as well as the installation of anchor bolts and embedded sleeves with high verticality requirements. Background technique: [0002] In the field of precision engineering measurement, it is necessary to bury mandatory alignment marks. The buried mandatory centering marks are vertical and vertical, and the top surface is horizontal. To achieve the above purpose, the known embedding method is: install three height-adjustable outriggers on the mandatory centering mark, first anchor the lower half of the three outriggers on the measured medium, and then adjust the height of the three outriggers. The height of the leg is to reach the level of the top surface of the sign, and finally the upper half of the three legs, together with the sign, is consolidated with the measured medium with concrete. With ...

Problems solved by technology

Adopt known method, need to make complicated, and is the intermediate conversion device of one-time use, and manufacturing cost is high, and installation is very complicated, is difficult to adopt in large quantities

In the construction of high-speed railway, the number of track control points that need to install mandatory alignment marks is huge, and the installation space is limited, so it is not suitable to install according to known methods
