Description
Technical Field
The application relates to the technical field of construction and installation, in particular to a laser plumb line measuring device and a laser plumb line measuring system.
Background
In the construction field, the reverse construction method is the most advanced construction technology method of high-rise buildings, and has the advantages of material saving and environmental protection, so that the reverse construction method is increasingly widely applied to deep and large foundation pit engineering with higher environmental protection requirements. In the construction of the underground structure by the reverse construction method, a temporary supporting upright post and a permanent structure upright post are often combined into a whole, namely, a steel pipe column or a steel lattice column is adopted as the temporary supporting upright post in the construction stage of the foundation pit engineering, and reinforced concrete is wrapped outside the temporary supporting upright post after the foundation pit engineering is finished to form the permanent structure upright post; the construction quality of the temporary supporting upright post is required to be high, the axis deviation of the structural upright post is regulated to be within +/-5 mm by the specification, and the verticality is controlled to be within 1/500-1/600; the control of the verticality of the axis of the structural upright is a key technology of the structural reverse construction method.
In the process of installing the electric power tower pole, the same problem exists, in order to control the verticality of the tower body, the verticality detection is required to be carried out every 1 to 2 sections, and the installation can be continued after the verticality detection is adjusted; after the whole tower body is installed, the verticality of the tower body is well adjusted, and the platform can be hoisted only after the fixing bolt is screwed down; after the whole tower structure is completed, the verticality also needs to be adjusted to the optimal state (specification requirement is 1/2000).
The verticality of a tower mast component in wireless communication is not greater than 1/1500 of the measured height during installation and use, so the market also expects an efficient verticality detection technology.
In the traditional installation process, in order to ensure the verticality of a single upright post (component) and a steel pipe, the theodolite is usually used for manual measurement and monitoring for many times before and after hoisting operation, so that the time is consumed, and the efficiency is low; and particularly, the cost for monitoring the verticality of the large-scale supporting upright column of the reverse construction method is very high. How to guarantee the straightness that hangs down of stand when installing to carry out quick safe construction, be present technological problem. Except for using equipment such as an external theodolite to carry out external detection, the traditional steel stand column verticality detection method mainly comprises the following steps of: inclinometer tube methods and inclinometer methods. These methods are also used for the installation of power towers and tower mast components in wireless communications.
An inclinometer tube method: binding a inclinometer pipe on the outer side parallel to the axis of the steel upright, and measuring a plurality of points in the inclinometer pipe by using an inclinometer to calculate the perpendicularity of the steel upright after the steel upright is placed in a prepared mounting hole; guiding to adjust the verticality of the steel upright according to the measurement result, then retesting, and if the verticality of the steel upright does not meet the requirement, repeating the previous operation steps until the verticality requirement of the steel upright is met; according to the test method, the verticality of the steel upright column with a longer length is adjusted to be more than 1/500 meeting the design requirement, the process of measuring → adjusting → retesting → … … is time-consuming and labor-consuming, and the efficiency is very low; meanwhile, the measuring method is influenced by various factors and cannot achieve high precision, because: the manufacturing method comprises the step of measuring the production error of the inclined tube. Wall thickness of the inclinometer pipe and depth error of the guide groove; errors of the inclinometer caused by temperature changes at the bottom and the top of the inclinometer; and errors caused by the way that a measurer pulls and releases the rope.
Inclinometer method: when the verticality of the steel upright is measured by the inclinometer, firstly, the steel upright is hoisted by a crane, then the verticality of the steel upright is measured and adjusted by the laser theodolite, and when the steel upright is completely vertical, the inclinometer is fixed and set as a zero position; then, in the orthogonal direction, positioning the inclinometer by the same method and returning to zero, so that the installation of the inclinometer on the steel upright can be determined; the main defects of the inclinometer method are that the installation and positioning of the inclinometer on the steel upright post are extremely difficult, the work efficiency is too low, the material cost is too high, and the inclinometer method is difficult to popularize and apply in engineering.
In the prior stage, the verticality real-time monitoring during the installation of a large component is completed by adopting a mode of combining a laser generator and a two-axis inclinometer; the method is that a device combining a laser generator and a two-axis inclinometer is arranged on the ground and at one end of a large member, laser is emitted along the axis direction of an upright post, the position condition of the light spot on the target paper is observed, and the positions of the light spot on the target paper at different upright post positions are basically consistent by adjusting the installation plane of the inclinometer, so that the installation plane of the inclinometer is determined to be vertical to the axis of the upright post; after hoisting, the verticality of the upright post is indirectly measured by installing an inclinometer and detecting the levelness; this method has advantages over inclinometer and single inclinometer methods.
The existing laser generator and two-axis inclinometer integrated equipment has some disadvantages, including:
(1) only horizontal direction detection in X and Y directions is used, and three-axis attitude detection of the upright X, Y, Z is not realized;
(2) the wireless communication is not integrated, the equipment volume is large, the automation degree is low, and the use is complicated;
(3) the Z-axis measurement value is lacked, and when the integrated equipment mounting plane is vertically adjusted with the axis of the upright column on the ground, the batch coarse adjustment cannot be carried out, the adjusting speed is low, and the efficiency is low;
(4) when the mounting plane is vertically adjusted with the axis of the upright column, the distance between the laser beam and the upright column is detected by manual measurement and recording, the analysis and processing efficiency is low, and the adjustment speed is influenced;
(5) after the adjustment of the installation plane is finished, if unauthorized adjustment of the installation plane is carried out, the unauthorized adjustment of the installation plane is difficult to find;
(6) the operation and application threshold is high, the difficulty is high, and the professional is required to process the operation and application threshold.
The prior art integration level is low, degree of automation is low, and the function is single, lacks stand X, Y, Z triaxial gesture and detects, influences the efficiency of construction greatly.
