Commissioned by Zhangjiakou Xuanhua District Urban Construction and Investment Co., Ltd, our company undertook the underground pipeline survey and mapping project in the main urban area of Xuanhua District. The underground pipeline detection scope of Xuanhua main urban area is north to the North Outer Ring Road, west to Liuchuan River, south to Yanghe River, and east to Changsheng Road (not including Xuanhua Iron and Steel Group Co., Ltd). Covering the entire Xuanhua main urban area of about 46 km2, the total length of the road is about 180 km, including water supply, drainage, gas, heat, power, communication, radio and television, industry, energy and other pipelines, ancillary facilities, station facilities and dangerous site sites buried on both sides of the main and secondary roads in the main urban area of the city.
The project was started on May 30, 2018, and completed all physical prospecting field surveys and pipeline point field measurements until April 20, 2019. The total number of pipeline points surveyed is 103,507, including 48,774 obvious pipeline points and 54,733 hidden pipeline points. The total length of pipeline surveyed is 1,870.553 km, with 434 comprehensive pipeline maps.
The drainage pipeline management system uses physical prospecting technology, mapping technology, computer technology, GIS technology, network technology, and database technology to obtain, store, edit, query, count, analyze, and output all pipeline information in digital form to provide accurate basic information of drainage pipelines for the construction and development of the city.
On August 5, 2020, it successfully passed the inspection and acceptance of Hebei Provincial Surveying and Mapping Product Quality Supervision and Inspection Station, and was highly recognized and praised by the owner.
