MPP电力管地基施工注意事项

MPP电力管地基施工要注意两点：
Two points should be paid attention to in the foundation construction of MPP power pipe:
1.地基要稳
1. The foundation should be stable
MPP电力管地基施工考虑管材要承受土压,车轮载荷等大负载。如果地基不稳,容易使管材产生弯曲,局部负载过大，因此要注意把地基打好。
For MPP power pipe foundation construction, it is considered that the pipe shall bear large loads such as earth pressure and wheel load. If the foundation is unstable, it is easy to bend the pipe, and the local load is too large, so pay attention to the foundation.
2. 要保证地基不要沉降
2. Ensure that the foundation does not settle
地基沉降会导致MPP电力管破裂。
The foundation settlement will cause the MPP power pipe to break.
MPP电力管地基施工注意事项：
Precautions for MPP power pipe foundation construction:
一般来说，MPP电力管地基施工先要将沟底挖平,使放在其上的管枕平坦不倾斜。
Generally speaking, the foundation construction of MPP power pipe should first level the trench bottom so that the pipe sleeper placed on it is flat and does not incline.
1. 如遇土质比较松软的地方,管材有可能不均衡下沉,建议在管枕下铺100MM的细石沙,并加在夯实。
1. If the soil is relatively soft, the pipe may sink unevenly. It is recommended to lay 100mm fine stone sand under the pipe sleeper and add it to the compaction.
2. 如果土质较差,遇到暗沟或小河时,应先进行如下处理:
2. If the soil quality is poor, the following treatment shall be carried out in case of underground ditch or small river:
（1）挖除河沟内淤泥
(1) Remove the mud in the ditch
（2）用大石块压实
(2) Compact with large stones
（3）分层夯实回填土
(3) Layered and compacted backfill
