Technical Problem
[0004]针对现有技术中利用挖除和挤压方式形成孔洞缺陷都会干扰土体,破坏孔洞周围土体初始的密实度,进而影响土体的力学性能无法得到准确的试验结果的问题
Benefits of technology
本实用新型通过外壳与内壳的转动配合,结合由活动弧板和刀组构成的活动件,能精准对土体进行环形切割,有效避免传统挖除、挤压方式对孔洞周围土体初始密实度的干扰,保障土体原有性质,为后续土体力学性能试验提供准确样本基础,其次内壳顶部的插入刀片可降低装置插入土体的阻力,提升操作效率,且刀组通过螺丝快拆设置,便于更换维护,适应不同密实度土体切割需求,再者推泥板配合连接杆、推板及拉力弹簧,能在切割取土后平稳推出内壳内土体,完成取样后还可自动复位,进一步提高了装置的实用性。

Abstract
The utility model belongs to experimental apparatus technical field, concretely is a kind of soil non-penetrating type hole defect production device, including shell and inner shell.The utility model can be accurate to soil annular cutting by the rotation cooperation of shell and inner shell, combined with the movable piece formed by movable arc plate and knife group, effectively avoid the interference of traditional dig out, extrusion mode to the initial density of soil around hole, guarantee the original property of soil, provide accurate sample basis for subsequent soil mechanics performance test, secondly, the insertion blade of inner shell top can reduce the resistance of device insertion soil, improve operation efficiency, and knife group is set by screw quick release, it is convenient to replace maintenance, adapt to different density soil cutting demand, furthermore, push mud board cooperation connecting rod, push plate and tension spring, can smoothly push out inner soil in inner shell after cutting and taking soil, after sampling, it can also be automatically reset, further improve the practicability of device.
