Steel casing pile stabilizing construction device under conditions of shallow covering layer and bare rock
The invention relates to the field of steel casing construction, in particular to a steel casing pile stabilizing construction device under shallow covering layer and bare rock conditions, which comprises a steel casing body. According to the steel casing pile stabilizing construction device under the conditions of the shallow covering layer and the bare rock, when the bottom of the steel casing body abuts against the surface of a rock layer, the first air bag is expanded and swelled, so that the sealing performance of the first air bag on the scraggly rock surface is better, slurry leakage between the bottom of the steel casing body and the surface of the rock layer is avoided, and meanwhile, when slurry is filled, the steel casing pile stabilizing construction device is convenient to use. The pressure intensity of slurry is used as power, the first air bag is further expanded, the sealing effect of the first air bag is better, the second air bag is expanded outwards and abuts against the inner wall of a hole, the steel casing body can be prevented from inclining in the construction process, the friction force between the steel casing body and the inner wall of the hole can be improved, and the construction effect and quality are guaranteed; impact force generated when slurry flows is used as power, the inner wall of the steel casing body is knocked and vibrated in a reciprocating mode, and therefore it is guaranteed that the filling effect of the slurry is better.
本发明涉及钢护筒施工领域，具体的说是一种浅覆盖层及裸岩条件下钢护筒稳桩施工装置，包括钢护筒本体。该种浅覆盖层及裸岩条件下钢护筒稳桩施工装置，能够在钢护筒本体底部与岩石层表面相抵时，第一气囊进行膨胀鼓起，使其对凸凹不平的岩石表面密封性更好，避免钢护筒本体的底部与岩石层的表面之间漏泥浆，同时，能够在填充泥浆时，利用泥浆的压强为动力，使得第一气囊进一步膨胀，使其密封效果更好，使得第二气囊向外膨胀并与孔的内壁相抵，能够避免钢护筒本体在施工过程中发生倾斜，还能提高其与孔内壁的摩擦力，保证施工的效果和质量，并且，利用泥浆流动时的冲击力为动力，对钢护筒本体内壁的往复敲击震动，从而保证泥浆的填充效果更好。
