    • PURPOSE: A prefabricated portable pile driver is provided to enable a worker to easily and rapidly confirm the density of the ground through the driving number and height of a pile. CONSTITUTION: A prefabricated portable pile driver(100) comprises a knob part(110), a pile driver body part(120), a pile driver plumb part(130), and a pile driver cap part(140). The pile driver body part is detachably coupled to the knob part. The pile driver plumb part is inserted into the pile driver body part to be vertically movable. The pile driver cap part is coupled to the pile driver body part, and a part of a pile is inserted into the pile driver cap part.
    • 目的:提供一种预制便携式打桩机,使工作人员能够通过桩的驾驶次数和高度轻松快速地确认地面的密度。 构成:预制便携式打桩机(100)包括旋钮部分(110),打桩机主体部分(120),打桩机铅垂部分(130)和打桩机帽部分(140)。 打桩机主体部分可拆卸地联接到旋钮部分。 打桩机铅垂部分被插入打桩机主体部分,以便可垂直移动。 打桩机帽部分与打桩车身部分相连,一部分桩被插入打桩机帽部分。

    • A load test apparatus for a piled structure is provided to design piled structure which is optimized based on database by establishing the exact database through independently obtaining main surface load database and front end load database. A load test apparatus for a piled structure comprises: a soil tank(4) in which a ground(2) is created; a piled structure(6) whose part is laid under the ground of the soil tank; a loading equipment(8) applying the load on the piled structure; a displacement measuring unit(10) measuring main surface displacement of the piled structure; and one or more front end load gages(20) installed below the piled structure. One or more displacement measuring units are installed at the main surface of the piled structure. The front end load of the piled structure is obtained from the front end load gage. The cross-sectional size of the piled structure is fixed.
    • 提供了一种堆叠式结构的负载试验装置,通过独立获得主表面载荷数据库和前端装载数据库,建立了基于数据库优化的桩结构。 一种用于堆叠结构的负载测试装置,包括:土壤罐(4),其中产生地面(2); 堆放的结构(6),其部分放置在土壤罐的地面下; 装载设备(8)将负载施加在堆叠结构上; 位移测量单元,测量堆叠结构的主表面位移; 以及安装在堆叠结构下方的一个或多个前端负载计(20)。 一个或多个位移测量单元安装在堆叠结构的主表面。 堆垛结构的前端负荷是从前端负荷计获得的。 堆叠结构的横截面尺寸是固定的。
