Safety type stress release hole construction method capable of eliminating soil squeezing effect
The invention provides a safety type stress release hole construction method capable of eliminating the soil squeezing effect, and belongs to the technical field of stress release holes. Comprising the following steps: S1, evaluating geological conditions; s2, performing pre-pressing treatment on the isolation trench; s3, drilling a stress release hole; s4, reinforcing treatment of the stress release holes; according to the construction method of the stress release holes, engineering characteristics of soil are fully known by evaluating geological conditions, a scientific basis is provided for laying of the stress release holes, and before the stress release holes are selected, isolation ditches are dug on the periphery of a laying area, and meanwhile, the stress release holes are formed. The combination of vacuum pumping and freezing treatment is adopted to treat the isolation ditch, the stress release holes are drilled in different areas, and the sand pile ring is arranged around each stress release hole, so that transmission of surface vibration waves caused during drilling can be effectively reduced and blocked, surface upheaval can be reduced, and the soil squeezing effect generated during construction of the stress release holes can be fully eliminated.
本发明提供了一种具有消除挤土效应的安全型应力释放孔施工方法，属于应力释放孔技术领域。包括以下步骤：S1、评估地质条件；S2、隔离沟预压处理；S3、钻取应力释放孔；S4、应力释放孔的加固处理；本发明的应力释放孔施工方法通过评价地质条件，充分了解土壤的工程特性，为应力释放孔的布设提供科学依据，且在选取应力释放孔前，在布设区域外围开挖隔离沟，同时，采用真空抽气+冻结处理的组合对隔离沟进行处理、分区域钻取应力释放孔，且在每个应力释放孔周围设置砂桩圈，能够有效减少、阻断钻孔时引发的地表振动波的传递，减少地表隆起，充分消除应力释放孔施工时产生的挤土效应。
