Cast-in-situ bored pile device for bridge engineering
The invention belongs to the technical field of cast-in-situ bored pile construction equipment, and particularly discloses a cast-in-situ bored pile device for bridge engineering, which is used for hole cleaning treatment of cast-in-situ bored pile construction, and comprises a gravel pump set for sucking slag-containing slurry in a drill hole, a grouting pump set for injecting replacement slurry into the drill hole, and an auxiliary mechanism, the device is used for impacting, guiding and crushing large-particle drilling slag deposited at the bottom of a drill hole. The pipe assembly provided by the invention injects the replacement slurry into the bottom of the drill hole and impacts the large-particle drilling slag deposited at the bottom of the drill hole, so that the large-particle drilling slag floats along with the impact flow, the crushing treatment of the large-particle drilling slag is further realized through the crushing assembly, and the crushed drilling slag is sucked and discharged out of the drill hole. The problem that in the prior art, when hole cleaning is conducted, large-particle drilling slag is not prone to floating along with mud and then is deposited at the bottom of a drill hole, and treatment is difficult is effectively solved.
本发明属于钻孔灌注桩施工设备技术领域，具体公开了一种桥梁工程用钻孔灌注桩装置，用于钻孔灌注桩施工的清孔处理，包括用于吸取钻孔内含渣泥浆的砂石泵组，以及用于对钻孔内注入替换泥浆的注浆泵组，还包括辅助机构，用于对沉积在钻孔底部的大颗粒钻渣进行冲击、导流、破碎处理。本发明提出的管组件将替换泥浆注入钻孔底部，并对沉积在钻孔底部的大颗粒钻渣进行冲击，使得大颗粒钻渣随着冲击流漂浮起来，进一步通过破碎组件实现了对大颗粒钻渣的破碎处理，从而在对破碎后的钻渣进行抽吸，使其排出钻孔外。有效的解决了现有技术中进行清孔时，由于大颗粒钻渣不易随泥浆漂浮，进而沉积在钻孔底部，导致难以处理的问题。
