Description

A laser vertical line measuring device and laser vertical line measuring system

technical field

The present application relates to the technical field of construction and installation, and in particular, to a laser vertical line measurement device and a laser vertical line measurement system.

Background technique

In the field of construction, the reverse method construction technology is the most advanced construction technology method for high-rise buildings. It has the advantages of material saving and environmental protection. Therefore, it is widely used in deep and large foundation pit projects with high environmental protection requirements. In the reverse construction of underground structures, temporary support columns and permanent structure columns are often combined into one, that is, steel pipe columns or steel lattice columns are used as temporary support columns in the construction stage of the foundation pit project, and they are outsourced after the foundation pit project is completed. Reinforced concrete becomes a permanent structural column; this puts forward high requirements for the construction quality of the temporary supporting column. The specification stipulates that the axis deviation of the structural column should be controlled within ±5mm, and the verticality should be controlled within 1/500 to 1/600; control The verticality of the axis of the structural column is the key technology of the structural inversion method.

In the installation process of the power tower pole, there is also the same problem. In order to control the verticality of the tower body, the verticality detection must be carried out every 1 to 2 sections, and the installation can be continued after adjustment; The platform can be hoisted only after the degree of adjustment is adjusted and the fixing bolts are tightened; after the completion of the whole tower structure, the vertical degree needs to be adjusted to the best state (the specification requirement is 1/2000).

The verticality of tower mast components in wireless communication is not greater than 1/1500 of the measured height during installation and use. Therefore, the market also expects efficient verticality detection technology.

In the traditional installation process, in order to ensure the verticality of a single column (component) and steel pipe, the theodolite is usually used for manual measurement and monitoring many times before and after the hoisting operation, which is time-consuming and inefficient. , the cost of verticality monitoring is very high. How to ensure the verticality of the column during installation, and how to carry out fast and safe construction is the current technical problem. In addition to the use of external theodolites for external detection, for the convenience of installation, the traditional verticality detection methods of steel columns mainly include: inclinometer method and inclinometer method. These methods are also used for the installation of tower masts in power towers and wireless communications.

Inclination tube method: that is to bind the inclinometer tube on the outside parallel to the central axis of the steel column, and then use the inclinometer to measure several points in the inclinometer tube after the steel column is lowered into the prepared installation hole to calculate The verticality of the steel column; adjust the verticality of the steel column according to the guidance of the measurement results, and then re-measure, if it does not meet the requirements, repeat the previous steps until it meets the verticality requirements of the steel column; it can be seen from the test method, To adjust the verticality of a long-meter-long steel column to more than 1/500 of the design requirements, it must be measured → adjusted → re-measured → adjusted → re-measured →... This process is time-consuming and labor-intensive, and the efficiency is very low; At the same time, this measurement method cannot achieve high accuracy due to the influence of many factors, because: (1) the production error of the inclinometer tube. The wall thickness of the inclinometer tube and the depth error of the guide groove; (2) the error caused by the temperature change of the inclinometer at the bottom and top of the inclinometer tube; (3) the error caused by the way the measuring personnel pulls and releases the rope.

Inclinometer method: When using the inclinometer to measure the verticality of the steel column, first lift the steel column with a crane, then use the laser theodolite to measure and adjust the verticality of the steel column at the same time, when the steel column is completely vertical, fix the inclinometer, Set the inclinometer to zero position; then in the orthogonal direction, use the same method to position the inclinometer and return to zero, so that it can be determined that the inclinometer is installed on the steel column; the main defect of the inclinometer method is that the inclinometer is in The installation and positioning on the steel column is extremely difficult, the work efficiency is too low and the material cost is too high, so it is difficult to popularize and apply in the project.

At this stage, a combination of a laser generator and a two-axis inclinometer has been used to complete the real-time monitoring of the verticality during the installation of large-scale components; The laser is emitted along the axis of the column, and the position of the spot on the target paper is observed. By adjusting the installation plane of the inclinometer, the positions of the spots on the target paper at different column positions are basically the same, so as to determine that the installation plane of the inclinometer is perpendicular to the axis of the column; After the lifting, the indirect measurement of the verticality of the column is completed by installing the inclinometer level detection; this method is already superior to the inclinometer method and the single inclinometer method.

Existing laser generators integrated with two-axis inclinometers have several disadvantages, including:

(1) Only the horizontal direction detection in the X and Y directions is used, and the three-axis attitude detection of the column X, Y, and Z is not realized;

(2) There is no integrated wireless communication, the equipment is bulky, the degree of automation is low, and the use is complicated;

(3) Lack of Z-axis measurement value, when the integrated equipment installation plane and the vertical axis of the column are adjusted vertically on the ground, it cannot be roughly adjusted in batches, and the adjustment speed is slow and the efficiency is low;

(4) When the installation plane and the axis of the column are vertically adjusted, the distance between the laser beam and the column is measured and recorded manually, and the analysis and processing efficiency is low, which affects the adjustment speed;

(5) After the installation plane adjustment is completed, if there is an unauthorized installation plane adjustment, it is difficult to find;

(6) The operation and application threshold is high and the difficulty is high, and professional personnel are required to deal with it.

The existing technology has low integration, low automation, single function, and lack of three-axis attitude detection of column X, Y, and Z, which greatly affects construction efficiency.
