【文章內(nèi)容簡介】 y should the pit ( groove ) bottom soil prehensive observation. ① soil and the color is the same。 ② soil hardness is uniform, there is no local soft or strong。 ③ soil moisture content is abnormal or not, there is no too dry or wet。 ④ pit ( groove ) in bottom walking or tamping shooting without tremor or hole sound phenomenon. Through the above observation to analyze and judge the pit ( groove ) bottom dig to old soil ( bearing layer of Foundation ), whether to continue to dig or processing. Trough inspection should focus on to a load bearing walls, wall, or other larger force parts of the mainly. II, brazing trough inspection Brazing is a hammer into the pit ( groove ) steel under the soil in certain depth, according to the number of hammering and has difficulty to judge the soil soft and has no hole, hole, curtain cave and soft bottom layer. Brazing procedure is as follows: ① according to the pit ( groove ) plans for the drilling sites, and drill detecting points are sequentially numbered drawing drill detecting point layout。 ② preparation of hammer and drill rod, a drill diameter engineering should be consistent, the heavy hammer is consistent。 ③ press drilling sequence number for drilling construction。 ④ drilling, requirements to consistent, hammer drop distance consistent. Each peration30CM ( called step ), recording a hammering number, fill in the drill rod detection record。 ⑤ After the end of the drill rod detection, to from go up by step analysis of brazing records, and horizontal analysis of drill hole between the number of hammering, can determine soil structure and soil hardness, and should be the number of hammering to
