Description

Technical Field

[0001] The utility model relates to the technical field of mud treatment, in particular to an integrated environmental protection and purification mud circulation system. Background Technique

[0002] During the pile foundation construction process, the mud discharged from the construction pile foundation contains a large amount of sand and stones and cannot be directly used for mud circulation. That is, it is necessary to first separate the mud from the sand and stones through a mud pond. Therefore, construction workers often need to set up a mud pond, make mud, and ensure the stability of the hole wall by circulating the mud. The mud has a certain viscosity and density, can closely adhere to the hole wall, effectively prevent the hole wall from collapsing. At the same time, the mud can also play a role in cooling the drill bit, reducing drill bit wear and improving drilling efficiency.

[0003] During pile foundation construction, most mud ponds are excavated from the ground. For example, the invention patent of CN 113738275 A discloses a pollution prevention construction method for bored cast-in-place piles in pile foundation engineering. If the bridge length in the project is relatively long, more excavated mud ponds are required, including: a mud pond is arranged on one side of the pile hole of the bored cast-in-place pile. The mud pond includes a secondary sedimentation tank, and the secondary sedimentation tank is divided into a primary sedimentation area and a secondary sedimentation area by an overflow plate. Its mud ponds are all excavated at the construction site, with a long construction period and high labor costs. After the subsequent construction is completed, additional mud pond backfilling treatment is required. Content of the Utility Model

The initial mud pool 17 is communicated with the top of the construction pile foundation 16, and the mud with drill cuttings overflowing from the drilled hole in the construction pile foundation 16 flows into the initial mud pool 17 under the action of gravity; The sediment separator 19 is used to process the mud pumped out by the first mud pump 18, and preliminarily separates the thick mud and sand and gravel. The first mud pump 18 is connected to the inlet end of the sediment separator 19 through a pipeline; The mud tank mechanism, combined Figure 2 with Figure 3 shown (for convenient viewing, Figure 2 and Figure 3 are both rotated 90°), includes at least two mud tanks 2. The bottom of the mud tank 2 at the frontmost position is provided with a slurry inlet pipe, and the thick mud separated by the sediment separator 19 is introduced through the slurry inlet pipe, that is, the inlet end of the slurry inlet pipe is connected to the mud outlet end of the sediment separator 19. The bottom of the mud tank 2 at the rearmost position is provided with a second mud pump 15. The mud tanks 2 are communicated with each other through a water passing pipe 3 arranged on their upper parts. The mud is gradually precipitated in the mud tanks 2 of the mud tank mechanism. The sand and gravel precipitate at the bottom of the mud tank 2, and the upper-layer mud flows into the subsequent mud tank through the water passing pipe until it reaches the mud tank 2 at the rearmost position. The multi-stage precipitation separates the mud and sand and gravel better. Herein, the mud tank 2 at the frontmost position and the mud tank 2 at the rearmost position refer to the front and back order of processing the mud; The slag collection tank 20 is arranged on one side of the sediment separator 19 and is used to store the sand and gravel separated by the sediment separator 19. When drilling a cast-in-place pile, the mud in the construction pile foundation 16 circulates and overflows to the initial mud pool 17, and is pumped to the sediment separator 19 by the first mud pump 18; The sediment separator 19 separates the pumped mud, sand and gravel. The mud flows into the mud tank 2 at the frontmost position, and the sand and gravel are separated into the slag collection tank 20 and are promptly transported away by a muck truck; The mud flows into multiple mud tanks 2 in the mud tank mechanism in sequence, so that the smaller particles of sand and gravel that are not separated in the mud are fully precipitated.
