Anti-smashing guide box method for wall pile drilling and its anti-smashing guide box structure

This case belongs to the field of construction technology of field cast-wall piles, especially a kind of field-casting wall that uses the anti-smashing guide box to assist the guiding drilling tool and the anti-smashing construction technology for the easy-to-draw floor layer in the construction to prevent the hole wall from falling. Pile-drilling anti-smashing positioning method and device thereof.

According to the field, the cast-in-wall pile or the wall-type pile (Barrette) refers to the construction of a rectangular wall-drilling machine, and the shape is a single rectangular or a plurality of rectangular units combined into a pile. According to the domestic building infrastructure design code, it refers to the "collective continuous wall as a pile pile user, called a wall pile". In recent years, due to the construction technology of deep excavation and reverse construction in Taiwan's metropolitan area, and the demand for huge vertical column loads of super high-rise buildings, the general wall piles are more likely to be used under the same unearthed volume and materials. Large-caliber field cast round piles provide greater pile area and friction, and can be used as a good foundation or a mid-wall in deep excavation to reduce wall deformation in proper excavation. .

Generally, when the wall pile is applied, the installation hole is drilled down from the ground, and the installation hole is filled with a stabilizer liquid in advance to prevent the wall of the hole from falling, but the surface of the ground is tens of centimeters to 1 to 2 meters below the ground. The layer is a highly degradable stratum structure. Generally speaking, as long as the heavy machinery is close, it cannot be self-supporting and degraded. Therefore, before the actual construction, the lighter tools (such as excavators) will be placed on the wall pile before the actual construction. The location and its surroundings are used for shallow excavation and applied as reinforced concrete guide walls to prevent construction accidents caused by heavy machinery applied to the wall piles and to cause the earth to fall. The loose sand or weak is often located below the surface of the surface. An easy-to-floor layer composed of clay, etc., which is characterized by being allowed to stand for a period of time during excavation or drilling, or being easily disturbed by the disturbance of the drilling machine construction, and the depth of the distribution of the easy-to-floor layer Generally there are several meters, even more than ten meters. In order to solve this problem, there are generally two methods, and please refer to Figure 1 and Figure 2, which are schematic diagrams of the state of the conventional flood prevention method (1) and two). As shown in the figure, after the large-scale slope excavation, the first method is to construct the deep guide wall 1 and the backfill earthwork 2, and the first method is to construct the bottom guide wall 11 and the backfill bottom layer. Earthwork 21, then construct the second layer of guide wall 12 and backfill the second layer of earthwork 22, and finally construct the upper guide wall 13 and backfill the upper layer of earthwork 23, after the construction of the guide walls 11, 12, 13 is completed, When constructing a pavement 14 and not using the slope excavation, it shall be applied as a tamper-proof measure such as the steel sheet pile 3 and perform vertical excavation. After the excavation is completed, the aforementioned guide walls 11, 12, 13 may be constructed and The earthwork 2 is backfilled in stages, and the pavement 14 is finally removed after the steel sheet pile 3 is removed. The above-mentioned anti-tanning method is applicable to a depth of up to 5 to 6 meters. However, another method is to apply the ground curing method such as high-pressure jet cement pile 4, and then shallow excavation, and then the shallow guide wall 5 is applied. This method is suitable for up to 5~15 meters. depth.
