Construction method of deep foundation pit support based on rock stratum with soft upper part and hard lower part
The invention discloses a construction method of a deep foundation pit support based on a rock stratum with a soft upper part and a hard lower part, and relates to the technical field of building construction.The construction method comprises the following steps that firstly, a construction position is planned; secondly, two auxiliary holes are formed in the ground in a rotating mode through a hole-forming rotating machine, two wing pipes are placed in the auxiliary holes, concrete is poured into the auxiliary holes, the two wing pipes are pulled out, the main holes are formed in a rotating mode through the hole-forming rotating machine, a reinforcement cage is vertically placed in the main holes, concrete is poured, and a fender pile is formed; 3, manufacturing a plurality of groups of guard piles, wherein the plurality of groups of guard piles on the same straight line form a guard wall; 4, manufacturing a plurality of groups of parapet walls, and connecting the parapet walls end to end to form a support fence; fifthly, anchor rods are manufactured, and the outer ends of the anchor rods are fixed to the top beams; sixthly, a second layer of the soil layer in the supporting fence is excavated, the anchor rods are manufactured again, and the outer ends of the anchor rods are fixed to the fender piles; seventhly, the sixth step is repeated until the depth of the soil layer in the supporting fence reaches the needed depth, and the purposes of being safer and more economical are achieved.
本发明公开了一种基于上软下硬岩石地层的深基坑支护的施工方法，涉及建筑施工技术领域，本发明包括如下步骤：一、规划好施工位置；二、利用成孔转机在地面转出两个副孔，在副孔内放置两个翼管，往副孔内浇筑混凝土，抽出两个翼管，利用成孔转机转出主孔，往主孔内垂直安放钢筋笼，并浇筑混凝土，形成护桩；三、制作若干组护桩，同一直线上的若干组护桩形成护墙；四、制作若干组护墙，首位相连形成支护围栏；五、制作锚杆，将锚杆的外端固定在顶冠梁上；六、将支护围栏内的土层挖去第二层，再次制作锚杆，将锚杆的外端固定在护桩上；七、重复步骤六，直至支护围栏内的土层深度达到所需的深度，本发明实现了更加安全，而且经济的目的。
