Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mud treatment, in particular to an assembled mud box device and an integrated environmentally friendly purification circulating mud system comprising the device. Background Art
[0002] In the process of pile foundation drilling construction, mud plays a very important role. Mud has a certain viscosity and density, which can fit closely to the hole wall and effectively prevent the hole wall from collapsing. At the same time, mud can also cool the drill bit, reduce drill bit wear, and improve drilling efficiency. The mud in pile foundation drilling construction can be recycled, but the mud discharged from the construction pile foundation contains a lot of sand and stones, which cannot be directly used for mud circulation. It needs to be pumped to the mud pool first, and the mud is separated from the sand and stones before being transported to the construction pile foundation. Therefore, a mud pool needs to be set up at the pile foundation construction site for mud circulation to meet the requirements of engineering construction.
[0003] During pile foundation construction, most mud pools are excavated from the ground. For example, the invention patent CN 113738275 A discloses a method for anti-pollution construction of bored piles in pile foundation engineering. If the length of the bridge in the project is long, the number of excavated mud pools needs to be matched more, including: setting a mud pool on one side of the pile hole of the bored pile, and the mud pool includes a secondary sedimentation pool, which is divided into a primary sedimentation area and a secondary sedimentation area by an overflow plate. The mud pools are all excavated at the construction site, with a long construction period and high labor costs. After the subsequent construction is completed, additional mud pool backfilling is required. Summary of the invention
