The invention relates to the technical field of rock and soil mechanics, and discloses a lateral pressure test device which comprises a lateral pressure device, pressurization equipment and signal detection equipment used for detecting lateral pressure data signals generated when soil around the lateral pressure device deforms, the lateral pressure device comprises an expansion sleeve and a protection sleeve, and the pressurization equipment is communicated with the expansion sleeve; the expansion sleeve can expand under the action of the pressurization equipment, the protection sleeve is arranged outside the expansion sleeve in a sleeving mode, and the diameter of the protection sleeve can be increased along with expansion of the expansion sleeve. When the lateral pressure device is installed in a drill hole, the protective sleeve can protect the expansion sleeve, so that the situation that broken stones or other hard objects located on the hole wall of the drill hole possibly damage the lateral pressure device is avoided, and the service life of the lateral pressure device is prolonged; meanwhile, during use, the expansion sleeve abuts against the hole wall of the drill hole through the protective sleeve, so that the situation that the expansion sleeve is prone to damage is further avoided, and the service life of the lateral pressure device is further prolonged.
本申请涉及岩土力学的技术领域，公开了一种旁压试验装置，其包括旁压器、加压设备以及用于检测旁压器周边土体变形时产生的旁压数据信号的信号检测设备，旁压器包括膨胀套以及保护套，加压设备与膨胀套连通，以使膨胀套在加压设备的作用下能够膨胀，保护套套设于膨胀套的外部，且保护套的直径能够跟随膨胀套的膨胀而增大。本申请将旁压器安装至钻孔中时，保护套能够对膨胀套进行保护，以避免位于钻孔孔壁的碎石或者其他较为坚硬的物体可能对旁压器造成损坏的情况，从而增加了旁压器的使用寿命；同时在使用时膨胀套通过保护套抵紧于钻孔孔壁，以进一步避免膨胀套容易损坏的情况，进而进一步增加了旁压器的使用寿命。
