01基土釬探工程.doc

一、 施工準備
（一） 材料要求
砂：一般為中砂。
（二） 主要機具
1、 工打釬：一般鋼釬，用直徑φ22～25mm的鋼筋制成，釬頭是60°尖錐形狀，釬長1.8～2.1m；穿心錘(重10kg)。
2、 機械打釬：輕便觸探器。
3、 其他：麻繩或鉛絲、梯子(凳子)、手推車、撬棍(拔鋼釬用)和鋼卷尺等。
（三） 作業條件
1、 基土已挖至基坑(槽)底設計標高，表面應平整，軸線及坑(槽)長、寬均符合設計圖紙要求。
2、 根據設計圖紙繪制釬探點平面布置圖，確定釬探點位置及順序編號，按照釬探圖及有關規定進行釬探并記錄。釬探點的布置依據設計要求，當設計無要求時，應按規范規定執行，也可參照表l-l執行。
First, construction preparation
(A) material requirements
Sand: generally in the sand.
(B) Major equipment
1, drill work dozen: General drill rod, with a diameter of φ22 ~ 25mm steel bars made of drill bits is a 60 ° cone shape, drill length 1.8 ~ 2.1m; mandrel hammer (weight 10kg).
2, mechanical play filler: Portable sounding device.
3, Others: hemp rope or wire, ladder (stool), trolleys, lever (pull drill rod used) and the steel tape and so on.
(C) Operating conditions
1, the base soil has been dug to the pit (tank), the end of the design elevation, the surface should be flat, axis and the pit (slot) length, width are consistent with design drawings.
2, according to the design drawings floor plan of Probe soldering, brazing determine the location and serial numbers of Probe, drill for exploration in accordance with the provisions of solder and related exploration and recorded. Solder the basis of Probe layout design, when design has no requirements, provisions should be standardized, but also the implementation of the light table ll.
