Reversible load box for self-balancing static load test pile of foundation pile
The invention relates to a load box for a self-balancing static load test pile of a foundation pile, and particularly relates to a reversible load box capable of repeatedly loading a test. The reversible load box for the self-balancing static load test pile of the foundation pile comprises a plurality of jacks, liquid inlet pipes, communicating pipes and a liquid outlet pipe, wherein the jacks areuniformly distributed between an upper plate and a lower plate of the load box; the liquid inlet pipes communicate with the jack I; the communicating pipes communicate with the adjacent jacks; the liquid outlet pipe communicates with the jack N and serves as an outlet of high-pressure liquid; two liquid inlet pipes and two communicating pipes between the adjacent jacks are arranged up and down; aloading cavity is formed between the top of a piston and a cylinder body; and a retrograde cavity is formed between a piston body and a cylinder body. The load box has the advantages that: 1, two different cavities in the load box are connected in series; 2, a high-pressure pipe with a one-way valve is used, so that the cost is reduced; 3, a movable middle plate is newly arranged, so that the stressed area of the piston for force transmission is increased; and 4, the requirement of the load box for the self-balancing static load test pile of an engineering pile is met.
本发明涉及一种用于基桩自平衡静载试桩的荷载箱，尤其是一种可以重复加载试验的可逆式荷载箱。一种用于基桩自平衡静载试桩的可逆式荷载箱，包括多个千斤顶、进液管、连通管和出液管，千斤顶均布在荷载箱的上板、下板之间；进液管与千斤顶Ⅰ连通；连通管连通相邻千斤顶；出液管与千斤顶N连通，作为高压液体的出口；进液管及相邻千斤顶间的连通管均为两个，上下设置；活塞的顶部与缸体之间形成加载腔，活塞本体与缸体本体之间形成逆行腔。本发明具有如下优点：1、设计双串联连接荷载箱内两个不同空腔；2、使用带单向阀的高压管，降低成本；3、新设一块活动中板，增加活塞传力的受力面积；4、符合工程桩自平衡静载试桩荷载箱要求。
