After a year of restoration from the water damage, the Juma River, which suffered the "23.7" heavy rainstorm disaster, has ushered in the improvement of the river. On August 11, the reporter learned from the construction party Beijing Urban Construction Group that the 62.5-kilometer Juma River improvement project has started and is expected to be completed by the end of next year. By then, the anti-scouring capacity of the Juma River bank will be significantly enhanced, and it can meet the flood discharge capacity of once in 20 years.

The banks of the Juma River in Fangshan District used to be a tourist destination for citizens to escape the summer heat and relax and vacation. However, after the "23.7" torrential rain, the river bank was washed away and the lives and property of residents in the surrounding towns and villages were also threatened.

Wang Wenlong, the on-site commander of the Fangshan District Water Damage Restoration Command of Beijing Urban Construction Group, introduced that the first batch of post-disaster restoration and reconstruction tasks of the Juma River have been completed, and a total of 4 batches of water-damaged water supply facilities and 3 batches of water-damaged sewage pipe networks have been repaired, involving 156 villages in 19 towns in Fangshan District; 215 roads and 540.7 kilometers of water-damaged rural roads have been repaired. In accordance with the requirements of "basic restoration in one year, comprehensive improvement in three years, and long-term high-quality development", the Juma River has now entered the stage of comprehensive improvement, which will further improve the landscape along the Juma River and build a safety line for surrounding towns.

It is reported that the 62.5-kilometer Juma River improvement project involves 29 kilometers of concrete front pier construction, wire mesh gabion slope reinforcement, and 6 bridge area protection masonry. Wang Wenlong further explained that "front pier construction" refers to digging deep down on the river bank and building a retaining wall to block the slope protection, which can prevent the river from eroding the slope protection and the collapse of both banks caused by the loss of sand and gravel; wire mesh gabions are metal meshes woven with lead wires with stones placed in them, which can maintain the stability of the embankment structure while the water flows through. In addition, the bridge area protection masonry is a protective device set on the bridge piers, which can effectively prevent the bridge piers from being damaged.

At the same time, the project also involves ecological restoration of an area of ​​65,000 square meters, which can improve the ecological performance of the river and river banks and reshape the river environment while meeting the flood control safety of the river.

In addition to the Juma River, Beijing Urban Construction Group will also implement the Dashi River improvement project with a total length of about 118 kilometers, the Hedgehog River improvement project with a total length of about 3.5 kilometers, and the main channel improvement project in Fangshan District with a total length of about 146.7 kilometers. In addition, geological disaster management projects involving damage management, damage repair, and damage maintenance at 16 towns and 374 points in Fangshan District are also being carried out simultaneously.
