Description

Technical Field

[0001] The present application relates to the technical field of bridge pile foundation construction, and in particular to a bored cast-in-place pile slurry processing system and method. Background Art

[0002] The bored cast-in-place pile technology has a mature construction process and strong applicability, and is widely used in the foundation construction of railway bridges.

[0003] Under relevant technology, mud wall protection method is often used in the construction process of bored piles. The mud used has the following functions: 1. Protect the hole wall and prevent the hole wall from collapsing; 2. Carry the drill cuttings out of the hole; 3. Used as a lubricant and coolant for drilling tools.

[0004] Regarding the above-mentioned related technologies, the mud loses its use value after drilling is completed, and the waste mud contains a large amount of viscous materials such as clay, sand, gravel, weathered rock, minerals and rock debris, which can neither be discharged directly nor settle. The use area of ​​the construction site is limited. If it is not handled in time, it will not only affect the construction, but also pollute the environment, and it is a public hazard of water pollution and sewer blockage. The direct discharge of waste mud without treatment will have many adverse effects on the ecological environment, causing the soil in the surrounding areas to become compacted and the land to become salinized, and lose its use value. In addition, the waste mud contains some soluble substances, such as high molecular polymers, which can increase the viscosity of the mud and can be recycled repeatedly. It is difficult to extract and recycle the soluble substances in the mud in the existing mud treatment system, resulting in a waste of available resources. Summary of the invention

When the mud cake is not cleaned, the handle 612 is pulled to slide the collecting plate 61 to the outside of the mud treatment box 2, and the dehydrated liquid is discharged from the drain pipe 26. When the mud cake is cleaned after the first dehydration is completed, the collecting plate 61 is slid along the second direction into the mud treatment box 2, and the cleaned liquid further falls into the collecting groove 611 of the collecting plate 61.

[0044] The implementation principle of the bored pile mud treatment system and method of the present application embodiment is as follows: the mud after drilling is passed into the mud mixing box 1 for uniform stirring, and then passed into the mud treatment box 2 through the first pipe 13 for fixed liquid separation, and the separated mud cake is passed into the solid treatment box 3 through the second pipe 23 for treatment; After the mud enters the mud treatment box 2, when the mud passes through the first filter plate 24, the first filter hole 241 filters the macromolecular solid particles in the mud, and the motor 43 drives the first rotating shaft 41 to rotate and drives the cam 42 to rotate. When the raised part of the cam 42 contacts the bottom wall of the first filter plate 24, the first filter plate 24 is driven to slide along the first direction, so as to facilitate the shaking off of the mud; The first rotating shaft 41 rotates to drive the cam 42 to rotate, and drives the first pusher 253 to slide along the second direction, and the second pusher 254 pushes the mud to the first feed trough 2511, and further enters the filter area 2521, and the cam 42 rotates, and the raised part of the cam 42 contacts and squeezes the filter cloth 252, and the first pusher 253 and the cam 42 squeeze the mud in the filter area 2521, and the squeezed liquid gathers on the bottom wall of the mud treatment box 2 and is discharged from the drain pipe 26; When the mud cake in the filter area 2521 needs to be cleaned again, the water pump 2543 is turned on, and the washing liquid is passed into the second pusher 254 through the liquid inlet pipe 2542, and then sprayed out from the spray hole 2541 to wash the mud cake with water, and further extract the soluble substances in the mud cake. The soluble substances after washing are further collected by the collecting tank 611. After dehydration, the mud cake enters the solid treatment box 3 through the second pipe 23 for the next step of treatment.

[0045] The present application also discloses a bored pile slurry treatment method, comprising the following steps: S1: Mud stirring: The mud is passed into the mud mixing box 1 for uniform mixing; S2: Mud solid-liquid separation: S21: Primary filtration of mud: The stirred mud is passed into the mud treatment box 2, and the first filter plate 24 is used to filter the macromolecular solid particles in the mud; S22: Mud squeeze: The filtered mud falls onto the filter cloth 252 and penetrates into the filter area 2521. The first rotating shaft 41 rotates to drive the cam 42 to rotate, and the first pusher 253 slides along the second direction. The convex part of the cam 42 and the first pusher 253 squeeze the mud in the filter area 2521. S33: Mud cleaning: The cleaning liquid is sprayed from the liquid spray port to clean the mud cake again, and the soluble substances after cleaning are collected by the collecting tank 611; S33: Separation of mud cake: The screw 51 rotates to drive the second pusher 254 to slide in the filtering area 2521 along the second direction, and transports the dehydrated mud cake from the discharge trough 2512 to the solid processing box 3 via the second pipeline 23.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
