施工质量检验①施工记录 施工过程中应由专人负责记录，详细记录每根桩的下

Construction Quality Inspection <br><br>① construction records <br>during construction shall be the person responsible for recording, detailed records of each pile sinking time, rise time, sinking speed, lifting speed, mortar production, the depth of the recording error no larger than 100 mm, the error shall not record time Greater than 5 seconds. Construction records must be checked at all times during construction. And the quality evaluation of each pile is carried out according to the specified construction process. <br>②The quality of the pile body <br>shall be tested for soil sampling of the borehole of the clay seal wall at intervals of 100 m after the mixing construction. The borehole shall be placed in the middle of the clay seal wall (after the borehole is completed, it shall be backfilled with clay balls). The sampling interval is 1 m, mainly Carry out particle analysis (including clay particles) and penetration test.

Construction quality inspection<br><br>(1) Construction records <br>During the construction process should be responsible for the record, detailed record of each pile sinking time, lifting time, sinking speed, lifting speed, mortar production, depth recording error must not be greater than 100 mm, time record error should not be greater than 5 seconds. Construction records must be checked at all times during the construction process. And against the prescribed construction process for each pile quality assessment.<br>(2) Pile quality<br>After mixing and construction, the clay sealwall was separated by 100 m drilling soil sample test, drilling arrangement clay sealwall in the middle position (after the drilling must be backfilled with clay ball), sampling spacing of 1 m, mainly for grain analysis (including sticky particles) and penetration test.

Construction quality inspection<br>① Construction records<br>During the construction process, special personnel shall be responsible for recording the sinking time, lifting time, sinking speed, lifting speed and mortar production of each pile. The depth recording error shall not be greater than 100 mm, and the time recording error shall not be greater than 5 seconds. Construction records must be checked at any time during construction. The quality of each pile shall be evaluated according to the specified construction process.<br>② Pile body quality<br>After the mixing construction, the clay sealing wall shall be drilled at an interval of 100 m for soil sample test, and the middle position of the clay sealing wall shall be arranged for drilling (the clay ball shall be used for backfilling after the completion of drilling). The sampling interval is 1 m, mainly for particle analysis (including clay particles) and penetration test.
