Problems solved by technology

[0004] However, in the above-mentioned construction area, it is difficult to bury ground control points: 1. Excavation of equipment foundation pits will damage the control points; 2. Rolling of construction vehicles; 3. Construction disturbance, etc.
Therefore, it is difficult to realize the conventional buried point method

Embodiment Construction

[0028] As shown in the figure: a method for measuring and setting up a control network in a densely populated area includes the following steps:

[0029] Part 1: Selection of the position and number of control points:

[0030] Firstly, survey and select reasonable reflector control points ② and ground temporary observation points ⑤ in the construction area. Main considerations: 1. Whether the control point ② of the reflector can be seen through, which is convenient for setting up stations in the future. 2. Control network coverage. 3. It is beneficial to the protection of the control point and prolongs the service life of the point. 4. Build the network graphics conditions to improve the strength of the graphics structure. 5. The location of the patch is conducive to the sticking of the reflective sheet to ensure firmness.

[0031] The number of points, in order to ensure the observation accuracy and the reflection signal strength of the reflector, the distance between two...

Abstract

The invention relates to a method for measuring and arranging a control network in an area with dense buildings. A target cooperation manner of a total station is used, reflector plates are pasted tothe side surfaces of the building and forms a triangular lock network with a temporary observation point in the ground, the lengths of triangle sides and diagonals are observed in the field, and the construction control network suitable for the construction area with dense building distribution is established via rigorous adjustment calculation. The method is higher in practically, improves the working efficiency, ensures the location precision, effectively solves the problem that control points in the construction area with dense buildings is difficulty in intervisibility and not easy to buryor protect, and is expansible and easy to use.

Description

technical field [0001] The invention belongs to the field of surveying and mapping engineering, in particular to a method for surveying and setting up a control network in a densely populated area of ​​buildings. Background technique [0002] In building construction, we often encounter situations where there are dense structures in the construction area, such as steelmaking, steel rolling workshops, electrolytic aluminum workshops and their purification systems for industrial buildings. In many cases, we only start after the main frame of the factory building is completed. Carry out the construction of the equipment foundation and the structure and equipment installation works. In order to ensure the positioning accuracy of subsequent construction, an encrypted control network must be established in this construction area. [0003] The survey and design process of the conventional control network mainly includes: selection and burial of ground control points-field observat...
