On February 20, 2022, China Railway 14th Bureau held a 120-day labor competition mobilization meeting to participate in the construction of the Xiaoqinghe resumption project, and launched a tough attack on the construction goal of completing the main project by the end of 2022.

Xiaoqinghe Resumption Project

The whole line of Xiaoqing River resumption is 169.2 kilometers long. There are many bridges, river channels, various water conservancy facilities, cross-river pipelines, and power lines along the line that need to be reconstructed. Among them, the China Railway 14th Bureau is mainly responsible for the construction of the second bid of the Xiaoqinghe River Resumption Project. The project spans two cities, two counties, and seven towns. The total length of the channel is 26.7km. One ship lock, four bridges, and irrigation There are 21 stations, 3 inverted siphons, 50 culverts and gates, 33 river crossing pipelines and 36 power cables.

Since the start of construction, the second bid section undertaken by China Railway 14th Bureau has completed the dry excavation of the waterway of 4.5 million cubic meters and the dredging of the waterway of 1.28 million cubic meters, completing 72% of the overall construction tasks. Faced with the tight construction period, the project department has completed the first large-diameter pipeline project DN1220 water supply pipeline directional drilling crossing, waterway earthwork and first-class bank protection project construction, and the closing of the left side of Pozhuang Bridge and other important construction nodes.

According to the requirements of the target task, the waterway project and water conservancy project will be completed on June 30, 2022, and other bridges, ship locks, water conservancy projects will be completed before the end of December, and the main project will be completed by the end of 2022.

In order to complete the labor competition goal on time, the builders of the China Railway 14th Bureau set up a special work team to strictly implement the construction period inversion and wall chart operations, and break down the construction tasks into days. Section guarantee, 24-hour shift work, go all out to ensure the progress of construction and production. They fully analyzed the characteristics of construction site operations, strengthened safety and quality control, established a QC research team, continuously optimized the construction plan, introduced 119 sets of advanced equipment such as unmanned surveying ships, and more than 300 workers in 28 labor teams started work at the same time to ensure construction tasks. Efficient promotion.

At the same time of construction and production, they insisted on green construction, compiled the "Special Implementation Plan for Green Energy Saving and Environmental Protection Construction", intensified the control of dust, and set up a three-stage sedimentation tank in advance to carry out secondary sedimentation and sedimentation of the generated mud and excavated sludge. The subsequent construction water will be recycled to ensure that the mud generated by the construction does not flow into the river.

It is reported that Xiaoqing River is the only river in Shandong Province that has multiple functions such as water-land combined transportation, river-sea combined transportation, farmland irrigation, aquaculture, etc., with a total length of 237 kilometers, a navigable section of 170 kilometers, and a drainage area of 10,336 square kilometers. The Xiaoqing River has a history of nearly 900 years since its excavation. It used to be a prosperous shipping waterway in history. It was suspended in 1997 due to multiple reasons such as insufficient water sources. After the resumption of the Xiaoqing River, the Haihe River intermodal transport can divert more than 40 million tons of bulk cargo each year, which is equivalent to rebuilding a Jiaoji Railway, which can raise the flood control standard from once in 20 years to once in 50 years.

According to the requirements of promoting ecological protection and high-quality development in the Yellow River Basin in the 14th Five-Year Plan, as the first river-sea combined transportation channel in the Yellow River Basin, the Xiaoqing River is a rare water transportation resource in my country, which has both the guarantee of people's livelihood and the development of society and economy. important function. With the accelerated implementation of the Xiaoqing River resumption project, the scene of numerous docks and prosperous commercial ports along the Xiaoqing River will reappear. At that time, the scene of people traveling from the Bohai Bay to the Quancheng 500-mile river basin in a boat and connecting the river to the Bohai Sea will be frequently staged on the Xiaoqing River.
