Therefore, the construction wastewater needs to be discharged in time using drainage devices to ensure safe production of the project.

[0003] Authorization announcement number CN216689646U discloses a construction engineering drainage device. After the construction wastewater is discharged, the construction engineering drainage device opens the impurity discharge port to remove impurities, and filters and removes impurities through a filter screen. This can not only prevent construction impurities and garbage from clogging subsequent pipes, but also ensure that the construction wastewater discharge meets the standards and does not pollute the environment. However, when the construction engineering drainage device is in use, due to the large impact force when the water flow is discharged, the filter screen is impacted by the water flow for a long time, which can easily cause damage to the filter screen. At the same time, construction impurities mixed in the water flow will also have a certain impact force on the filter screen, further increasing the possibility of damage to the filter screen, resulting in a reduction in the service life of the filter screen, affecting the drainage efficiency of the impurity removal box.

[0004] Therefore, it is necessary to provide a new construction engineering drainage device to solve the above-mentioned technical problems. Utility Model Content

Through the cooperation of the two reinforcing rods 104 and the first threaded rod 108, adjacent protective plates 101 can be connected together for use, making the protective plates 101 more firm and reliable when used. Similarly, the remaining protective plates 101 can be connected.
