Blasting Design Scheme for the Middle Route Project of South to North Water Transfer
Content introduction The channel is excavated with trapezoidal section stone. The designed channel bottom width is 8~14.5m, the channel bottom elevation is 88.781~88.363m, the first grade slope in the channel is 1:2.5~1:3.5, the first grade berm (embankment top) is 5.0m wide, the outer slope is 1:1.5, and the longitudinal gradient of the channel is 1/28000~1/23000. [Blasting scheme] The channel excavation of this project adopts layered and block bench blasting from top to bottom, and the layer thickness is determined according to the design requirements of the excavation structure. For those with a layer thickness of more than 5m, the down the hole drill is used to drill medium and deep hole bench controlled blasting, and for those with a layer thickness of less than 5m, the hand-held pneumatic drill is used to drill shallow hole bench controlled blasting. [Construction technology] The general sequence of blasting construction is: construction survey → mark the position of the blast hole → drill hole → check the blast hole → prepare the blasting materials → charge → connect the blasting network → lay safety sentries → block the blast hole → blasting coverage → blasting signal → blasting → eliminate misfires and deal with dangerous rocks → disarm → analyze the blasting effect and record the data. [Key points of the scheme] (1) Determine the reasonable q value of unit dosage. (2) Reasonably arrange the blast holes and charges to form a multi-point decentralized charging mode, so as to avoid the excessive concentration of charges in a single hole or single charge; The depth of blasthole shall be determined according to the actual situation on site, and it should be deep rather than shallow. (3) The key is to select the free surface. Through the selection of the free surface, the uniformity of the resistance line distance can be improved, and the direction of the flying stone can be controlled to the greatest extent.

The Middle Route Project of South to North Water Transfer starts from Danjiangkou Reservoir in Hubei, and enters Beijing through Hubei, Henan, Hebei and other provinces and cities. The main canal in Beijing section connects with the open canal section of Hebei Province from the south of the middle branch of the North Juma River, passes through the canal head intake gate, enters the underground canal of the North Juma River, reaches the Huinanzhuang pump station, raises water through the booster pump, and transfers water to the Daning surge tank through the PCCP water transmission pipeline. After Daning surge tank, low pressure concealed pipes are used for gravity water conveyance, passing through Yongding River inverted siphon, Lugouqiao low pressure concealed box, west fourth ring low pressure concealed box, and finally from Tuancheng Lake open channel to Tuancheng Lake, the destination, with a total length of 80km. The PCCP pipeline project is a large-scale water transmission project with the longest main canal line in Beijing section of the middle route of the South to North Water Transfer Project, which is connected to Huinanzhuang pump station on the top and Daning surge tank on the bottom. The starting point of the water transmission pipeline is 2.3km away from the canal head, and the end of the water transmission pipeline is about 21.4km away from the end of the main canal Tuancheng Lake in the Summer Palace. The total length of PCCP water transmission trunk line is 56.359km (including two tunnels, Xiganchi Tunnel and Chongqing Tunnel), which are two rows of PCCP pipes with a diameter of 4m. The PCCP water transmission pipeline project in Huinanzhuang Daning section is a Class I project, and the main buildings are Class 1 buildings. Taking HD41+000 as the boundary, the design seismic intensity of HD0+000 ～ HD41+000 is 7 degrees, and the design seismic intensity of HD41+000 ～ HD56+359.296 is 8 degrees.
