2.又根据该区域地质勘探孔，孔编号S-28、29数据表明，该区域地面以下43m范围内广泛分布着砂层和20m范围内存在较多的软土层，PC桩施工易造成卸压孔塌孔，从而起不到良好的卸压效果，这也是我方在认真分析厂区内地质勘察报告后，对于灌注桩成孔设备采用10型机回旋钻，而不采用旋挖机的原因，旋挖机成孔速度快，行走转移灵活，然其施工时，钻头在孔内对孔壁扰动很大，且钻杆提升过快，易造成孔内抽空，使孔壁所受压力陡然增大，特别是在砂层和软土较多的地层中，极易造成塌孔，使成桩质量难以得到保证，其次采用10型机成孔灌注桩来进行施工比采用旋挖机成孔，更为环保，后者成孔过程中产生的泥土是导致现场泞泥、湿陷的主要原因，故应选择采用10型机成孔灌注桩来进行施工。
3.采用10型机成孔灌注桩施工时，只要进行合理的施工布置、安排，现场场地及道路就可以控制的干净，整洁，以3#锅炉为例，根据现场施工布置图（见附页：3#锅炉灌注桩施工布置图），清水池提供钻孔所需水源，泥浆池容纳钻孔过程中产生的泥浆，当泥浆超过泥浆池容积的一半时，应通过泥浆泵将泥浆输送到废浆池，废浆池应设置在厂区外，且应及时进行清理，保证足够的空间。而采用PC桩施工，对厂区道路要求很高，运载PC桩的平板车反反复复对路面的碾压将会造成道路使用寿命缩短，造成地面坑陷、一旦遭遇雨天，地面将湿滑，泞泥不堪，可知采用10型机成孔灌注桩施工可以更好地保持场容和维护施工场地及道路。
综上所述，就实际情况而言，采用10型机成孔灌注桩来施工更具有优势也更具有意义。

2. Also in accordance with the regional geological exploration holes, hole No. S-28,29 data show that the region is widely distributed within the range of 43m below the surface sand and 20m range more memory in soft soil, PC easily lead to unload piles pressure bore hole collapse, which would not achieve good relief effect, which is also our earnest after the geological survey report analyzes the plant area, equipment used to pile into the hole 10 drilling machines maneuver without reason with auger , auger into the hole fast, flexible walking metastasis, when then its construction, drill holes in the wall of the hole on the large disturbance, and enhance drill too fast, easily lead holes were evacuated to a sharp increase in pressure on the cell walls large, especially in sand and soft soil formations more easily cause the collapse of the hole, making it difficult to get into the pile quality assurance, followed by 10-type machine into the hole pile for construction pore over with auger, greener earth into the hole which is generated in the process leading to the site muddy mud, collapsible main reason, it should choose a 10-type machine into the hole pile for construction.
3. 10-type machine into the hole when the pile construction, as long as reasonable construction layout, arrangement, live venues and roads can be controlled clean, tidy, with 3 # boiler, for example, according to the construction site layout (see page : 3 # boiler pile construction layout), clear pool of water needed to provide drilling, drilling mud mud pools accommodate generated in the process, when the mud more than half the volume of mud pools, should be transported by mud pump mud into a waste slurry tank, the waste slurry tank should be set up outside the factory, and should promptly clean up, to ensure adequate space. The use of PC pile construction, high requirements on plant roads, flatbed truck carrying piles of PC repeatedly rolling on the road will result in shortened life path, cause land subsidence pits, once encountered rain, the ground will be wet, muddy clay bear, found that 10-type machine into the hole pile construction can better maintain field capacity and maintenance and road construction sites.
In summary, in practical terms, the use of 10-type machine to pile into the hole construction has more advantages but also more meaningful.

Hole type 43M, S-28 2. According to the regional geological exploration hole, hole number 29 data show that the area below ground range widely in the distribution of sand and 20m more soft soil, PC pile construction is easy to cause the pressure relief hole collapse hole, so as not to good relief effect, this is my party in a careful analysis of the plant in the geological survey report, for pouring pile hole equipment using 10 machine swing drill, and the rotary digging machine, rotary digging machine speed, walking flexible transfer. However, the construction, the drill bit in the hole to hole wall is a great disturbance, and drill rod lifts too fast, easy cause hole evacuated the hole wall pressure suddenly increased.Especially in more sand and soft soil strata, extremely easy to cause hole collapse, making it difficult to guarantee the quality of pile, followed by 10 machine hole perfusion pile construction than the rotary digging machine into the hole, more environmentally friendly, the latter produced in the drilling process of the soil is field muddy and collapsibility of the main reasons leading to, so we should choose 10 machine hole filling pile construction. . the 10 machine becomes bored piles construction, as long as reasonable construction layout, arrangement, site and road can control the clean, tidy, to boiler 3 as an example, according to the construction site layout (see Appendix: 3 boiler perfusion pile construction layout diagram).To provide the necessary water source for the cleaning tank, the mud can be contained in the drilling process. When the mud is more than half of the mud pool, the slurry pump should be transported to the waste slurry tank, and the waste water slurry pool should be arranged outside the plant area, and should be cleaned up in time. And the use of PC pile construction, has a very high demand for Factory Road, carrying PC pile flatbed repeatedly on the pavement compaction will cause shorten the service life of the road, caused by pit ground subsidence, once encounter a rainy day, the ground would be wet, muddy unbearable, it can be seen that the 10 machine into hole perfusion pile construction can be better to keep the field capacity and the construction site and road maintenance.
To sum up, in the actual situation, the use of the 10 type machine into hole filling pile to construction has more advantages and more significance.
