Abstract I. The plan is the inter-annual plan for 2018-2019 years, and the second year (2019) plan, according to the Government Procurement Act Article 22 NO.7, the subsequent expansion of the original Procurement, in the following year (2019) No need open tendering, but the contractor who undertakes the first year of the project, the report of the final year (2018) result work report needs to be evaluated excellent by the review meeting and included in the conclusion of the meeting, and can continue to apply for the second year jobs. II. Field Survey work, based on river existing ross section position (involve Upstream and downstream of the bridge Cross sectioning), hydraulic routing and fluvial eomorphology Related conditions the appropriate position and quantity shall be selected, and the relevant work results shall meet the requirements of the “Measurement Work Specification” of the contract. III. Major work in the year 2018: control survey, hydraulic structures survey, orthophotoquad and Output Digital Elevation Model, profile, cross section sectional drawing fabrication for main stream streamway (Zhuoshui River main stream 321 cross section). IV. The first stage, the project control survey result was part qualified from September 25 to October 1, 2018; the second phase of acceptance (the project includes the river Cross sectioning and river Cross section and Profile picture produce) part qualified on November 28、29 and December 3、5,2018. V. This project investigation and laying of foundation piles, according to the contract, the placement of the stakes 20 positions and the navigation aids mark 50 positions, and the satellite static control survey coordinates are applied to the satellite control point. VI. This project horizontal control surveys use the Ministry of the Interior TWD-97 [2010] coordinate system second, third, etc. satellite control point 18 points for detection, after GPS satellite positioning measurement, after virtual baseline calculation, network adjustment, coordinate conversion calculation of coordinate results, control The angular error of each point of the point is within 20 seconds of the specification, and the deviation between the long side distance and the original data back calculation distance meets the requirements of the specification 1/10,000. VII. The Vertical Control in this report implemented “2015 Taiwan First Order Levelling Network Levelling Result” released by Ministry of Interior in 2016. Total of 16 measured points were qualified with the standard of 7mm√K, and these points were then drawn to cross sectional stake at site as the reference for the vertical control. VIII. The project investigated the existing flood control and river crossing structures of the Zhuo Shui River, including 152.957 km of flood control structures and dikes (Table 8); and 26 cross-river structures (Table 9). IX. The Output Digital Elevation Model results, Zhuoshui River mainstream area of about 20,015 hectares, according to the current 1 / 2,000 map, 1/2,400 (with river map), 1 / 5,000 (with the interior of the map) Digital Elevation After the Model framing, the number of mainstream 1/2,000 frames of Zhuoshui River was completed: 918; 1/2,400 frames: 574; 1/5,000 frames: 103. X. In the light of Output Digital Elevation Model results, and with the river section planning report of each river section to report the large section position and the newly-built section pile, to carry out and complete the terrain elevation of the large section of the river channel outside the current water area Point extraction and drawing work, in which the number of large sections of rivers produced according to the contract is 321 . After the integration of the 100-year and 104-year Curvature results of this Council, a total of 341 sections of the mainstream of the Zhuoshui River were completed this year. XI. This time, the river profile map is drawn according to the Section River heart distance of the original Review on the Regulation Planning of and the actual measurement of the deepest elevation of each Section.
