Problems solved by technology
The grouting method is to use the conduit poured with underwater concrete as a pipeline, and use a mud pump to press standard mud into the hole to suspend the sediment at the bottom of the hole and discharge it in positive circulation; when using this method to clean the hole, because the mud concentration is relatively thin , large particles will not be able to be suspended by the mud and discharged out of the hole, and the effect of cleaning the hole is poor
The pumping method is to use a mud pump to directly pump out the sediment and mud from the bottom of the hole. The hole is cleaned thoroughly. Since the mud is in reverse circulation in the hole, the original water level in the hole should always be maintained to prevent the hole from collapsing. When pumping deep holes Need to use high-power mud pump, the equipment is heavy and takes up space

The invention relates to the technical field of pile foundation cleaning, in particular to a pile foundation hole cleaning device. The pile foundation hole cleaning device is provided with a slurry separating device which includes a slag storing device, a main sand pump and an auxiliary slurry pump, wherein the slag storing device is provided with hand rings and a slag unloading switch, the main sand pump includes a base, a sand sucking opening and a sand discharging opening, and the auxiliary slurry pump is provided with a slurry sucking opening and a slurry spraying opening. The pile foundation hole cleaning device has the characteristics that the hole cleaning device is simple in package, light and convenient, hole-bottom self-circulation separation of slurry and sediment is achieved, the hole-bottom sediment can be completely removed, influence on the hole wall can be reduced, and pile quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of hole cleaning for pile foundations, in particular to a hole cleaning device for pile foundations. Background technique [0002] In the foundation construction of bored piles, the construction technology of punched piles is mostly used. Generally, the construction of bored piles needs to be cleaned twice. The first hole cleaning is carried out after the pile hole construction reaches the design depth, mainly to replace the mud, supplemented by the removal of sediment, and the performance of the mud basically meets the requirements as the standard. When cleaning the hole for the second time, the thickness of the sediment is calculated, and the relative density of the mud is adjusted at the same time to facilitate the hole inspection and meet the requirements of pouring concrete. [0003] Before the bored pile is filled with underwater concrete after the hole is formed, two processes of lowering the steel c...
