为了保证工程施工符合设计文件的要求，在施工之前就一定要把设计单位提交的

In order to ensure that the project construction meets the requirements of the design documents, all control pile points (such as plane control points, leveling points, etc.) submitted by the design unit must be reviewed and checked before construction. The work content of construction review and inspection specifically includes conductor, midline, leveling point and cross section. The main purpose of the construction review inspection is to check the accuracy of the original pile number, not to re-test. Therefore, after reviewing and checking, if the difference between the original point and the original result is within the allowable range, the original result shall prevail and no change shall be made. And after repeated review and determination, it is proved that the original results are wrong or there is a relatively large change in the point, and it should be reported to the relevant unit, and can only be changed after approval. Before construction, in addition to reverting to the middle pile, it can only be changed after being approved for the construction unit. Before the construction, in addition to the restoration of the middle pile, for the convenience of construction, a temporary leveling point needs to be added.

In order to ensure that the construction meets the requirements of the design documents, before the construction must be the design unit submitted all the control pile points (e.g. flat control points, level points, etc.) for review and testing. The work of construction review testing includes conductors, mid-line, level points and cross-sections. The main purpose of the construction review test is to verify the accuracy of the original station, not to re-test. Therefore, after reviewing the test, all the difference with the original results over-point points in the permitted range, all to the original results, no changes. And after a number of review and testing to determine, to prove that the original results of the error or location has a relatively large change, reported to the relevant units, after approval, can be changed. Before construction, in addition to replying to the middle pile, in order to the construction party related units, after approval and approval, can be changed. Before construction, in addition to the restoration of the middle pile, in order to facilitate the construction, it is also necessary to set up temporary level points.

In order to ensure that the project construction meets the requirements of the design documents, all the control pile points (such as plane control points, benchmark points, etc.) submitted by the design unit must be rechecked and tested before construction. The work content of construction recheck and inspection specifically includes conductor, central line, benchmark and cross section, etc. The main purpose of construction recheck detection and survey is to check the accuracy of the original pile number, rather than re survey. Therefore, after rechecking and testing, when the difference between the original results and the original results is within the allowable range, the original results shall prevail and remain unchanged. If it is confirmed through multiple rechecks and tests that the original results are wrong or there is a relatively large change in points, it shall be reported to the relevant units and can only be changed after approval. Before construction, in addition to reply to the middle stake, it can only be changed for the sake of relevant units of the construction party after approval. Before the construction, in addition to the restoration of the middle pile, in order to facilitate the construction, it is also necessary to add temporary benchmarks.<br>
