However, since the surface of the rock surface is not covered by soil layer, it is directly exposed under the water surface, and it is steep. If it is directly hit by a piling boat forcibly, the steel casing will be deformed and damaged before enterin

Embodiment 1

[0057] Step 1, such as figure 1 As shown, a drilling platform is built at the pier position, an impact drilling rig is placed at the drilling pile position of the drilling platform, and the drill bit 2 of the impact drilling rig impacts the exposed rock surface 1 below the water surface 3 without a steel casing .

[0058] Step 2, such as figure 2 As shown, the drill bit 2 impacts the exposed rock face 1 to form a partially flattened rock face 4 .

[0059] Step 3, if image 3 As shown, lower the steel casing 5, and after the steel casing 5 contacts the rock surface 4, lower the drill bit 2 in the steel casing 5.

[0060] Step 4, such as Figure 4 As shown, the drill bit 2 impacts the rock formation inside the steel casing, so that the rock surface 4 gradually forms a hole 6 with a certain depth and a diameter approximately the same as the outer diameter of the steel casing.

[0061] Step 5, such as Figure 5 As shown, mention the drill bit 2, place an alternative beating...

Abstract

The invention discloses a steel protection tube following method under a deep water inclined rock surface condition. The method comprises the following steps: step one, building a drilling platform in a pier position, placing an impact drilling machine in a drilling pile position of the drilling platform, and flatly impacting and tamping a river bed surface of the drilling pile position of the drilling platform through the impact drilling machine; step two, putting the steel protection tube down, enabling the steel protection tube to be in contact with the flat rock surface, drilling a hole with depth of 30-50cm in the rock surface on the inner side of the steel protection tube by using a drilling head, lifting up the drilling head and mounting a driving device at the top of the steel protection tube, striking and driving in short distance by using the drilling head and enabling the steel protection tube to gradually enter the hole; and step three, repeatedly carrying out the step two and enabling the steel protection tube to gradually follow into the preset depth. The steel protection tube following method has the advantages of simple operation, low cost and easily controllable perpendicularity and plane position of the steel protection tube.

Description

technical field [0001] The invention relates to the field of underwater construction of bridge foundations. More specifically, the present invention relates to a steel casing follow-up method in deep water inclined rock face conditions. Background technique [0002] Pile foundation, referred to as pile foundation, is a foundation composed of foundation piles and caps, and is mainly used in situations with poor geological conditions or high building requirements. The bridge foundation pile is a columnar component that penetrates into the soil layer, and is mainly used to bear the load of the bridge pier, the bridge superstructure, and the bridge during use; the cap is a reinforced concrete platform set on the top of the foundation pile and connected to the top of the pile It is mainly used to bear and distribute the load of bridge piers, bridge superstructure and bridge use. [0003] The steel casing is a temporary steel wall that stabilizes the hole wall, prevents the hole...
