Reusable deep load test device for open caisson construction period
The invention provides a reusable deep load test device for an open caisson construction period. The reusable deep load test device comprises a counter-force device, a loading device, a displacement limiting device and a displacement measuring device, wherein the counter-force device is used for fixing the loading device and providing counter force for the loading device during testing; the first end of the counter-force device is connected with an open caisson main body structure at an open caisson test hole, and the second end of the counter-force device extends into the open caisson test hole; the loading device is used for testing a test soil body in the open caisson test hole; the loading device is arranged in the open caisson test hole and is connected with the second end of the counter-force device; the displacement limiting device is used for limiting the horizontal displacement of the counter-force device in the open caisson test hole; the displacement limiting device is arranged on the outer side wall of the counter-force device and abuts against the inner side wall of the open caisson test hole; the displacement measuring device is used for measuring the displacement of the loading device in the vertical direction; and the displacement measuring device is connected with the loading device. According to the reusable deep load test device, a load test can be carried out on the soil body near a blade foot at the sinking depth of an open caisson at any depth in the open caisson construction period.
一种可复用的沉井施工期深层载荷试验设备，包括：反力装置，用于固定加载装置并在试验时为其提供反力；所述反力装置的第一端与沉井试验孔处的沉井主体结构连接，且第二端伸入所述沉井试验孔中；加载装置，用于对所述沉井试验孔中的试验土体进行试验；所述加载装置设置于所述沉井试验孔中，且与所述反力装置的第二端连接；位移限定装置，用于限制所述反力装置在所述沉井试验孔中的水平方向位移；所述位移限定装置设置于所述反力装置外侧壁上，且与所述沉井试验孔内侧壁抵紧；位移测量装置，用于测量所述加载装置的竖直方向位移量；所述位移测量装置与所述加载装置连接。本申请可在沉井施工期任意深度对沉井下沉深度处的刃脚附近土体开展载荷试验。
