[0002] The pre-embedded bolts on the foundation of large-scale factory equipment are numerous, widely distributed, and have corresponding specification requirements for the center point, verticality and spacing between the hole wall, etc., and need to be pre-embedded after the positioning position of the pre-embedded bolt on the equipment foundation is measured according to the drawings.

[0003] At present, the traditional method for setting the pre-embedded bolts of the foundation of large-scale factory equipment is as follows: the equipment foundation is constructed according to the drawings, a wooden formwork is erected, a settlement observation point or other permanent reference point is selected as a coordinate starting point, a total station or a theodolite combined level is used to measure the position of the anchor bolt after the wooden formwork is erected, a fixed wooden cross is erected, the anchor bolt is fixed on the fixed wooden cross by using an anchor frame and a tightening screw, and then the foundation is grouted for the second time, the anchor frame and the tightening screw are removed after the curing period of the concrete ends. This method for setting the pre-embedded bolts has a high degree of dependence on manpower, low positioning accuracy, and often causes the position of the pre-embedded anchor bolt to deviate, which often requires a large number of deviated pre-embedded anchor bolts to be removed and repositioned during the installation of the equipment, resulting in engineering rework, design changes and waste of construction materials, and adversely affecting the engineering progress and construction cost. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a device foundation bolt pre-embedding method based on BIM and GIS technologies, which can improve the positioning accuracy, shorten the construction period and reduce the construction cost.

[0005] To achieve this technical purpose, the present application adopts the following solutions:

[0006] A device foundation bolt pre-embedding method based on BIM and GIS technologies is performed according to the following steps:

[0007] S1, download the actual data information of the topography of the construction site generated by the GIS technology, and use the BIM technology to establish a model of the construction content;

[0008] S2, fit and correct the site model exported from the GIS system and the BIM model by means of the Navisworks software, and then import the coordinate information converted from the GIS system into the positioning robot to form a GIS positioning robot positioning system;

[0009] S3, fix the pre-embedded bolt by using a fixed anchor frame, and install it by using the GIS positioning robot;

[0010] S4, after the GIS positioning robot is positioned and installed, grouting is carried out by using a grouting system, after grouting is completed, the fixed anchor frame is removed, and the setting of the embedded anchor bolt is completed.

[0011] Compared with the prior art, the present application has the beneficial effects that:

[0012] The present application uses BIM and GIS technology to construct a three-dimensional information composite model of the construction site topography, converts the coordinate information of the GIS system into the GIS positioning robot to form a GIS positioning robot positioning system, determines the motion trajectory of the positioning robot, realizes the installation and positioning of the embedded bolt, transmits the BIM model from the design end to the construction end, realizes data integration on the GIS platform based on the BIM model, realizes the integration of BIM model design and construction, thereby improving the construction quality and efficiency, greatly increasing the installation accuracy of the embedded bolt, avoiding positioning deviation caused by human factors, improving the installation accuracy of the embedded bolt, reducing the construction cost and rework rate, and shortening the construction period.

[0013] Further, the preferred scheme of the present application is:

[0014] In step 1, according to the design drawing, a 1:1 three-dimensional information model of the equipment foundation and the embedded bolt is established by using BIM technology.

[0015] In step 3, the magnetic chuck of the GIS positioning robot is powered on, and the initial coordinates are positioned on the intersection of the longitudinal and transverse center lines of the fixed anchor frame. After the fixed anchor frame is sucked, the GIS positioning robot reads the embedded bolt site coordinate positioning data information imported into its device, uses the infrared position scanner of the GIS positioning robot to walk for positioning, places the bolt at the positioning point, waits for grouting, and uses the total station to recheck and test. After the embedded bolt is fixed on the fixed anchor frame, it is transported to the installation position by the positioning robot, and the positioning accuracy is higher.

[0016] In step 4, the grouting system is composed of a grouting car and a wooden formwork, and after the embedded bolt is placed at the embedded bolt positioning point by the GIS positioning robot, grouting is carried out, and after the concrete performance is stable, the wooden formwork and the fixed anchor frame are removed.
