Description

Technical Field

[0001] This utility model relates to the field of steel casing construction, and in particular to a positioning and stabilization system for steel casings on steep coastal rock surfaces. Background Technology

[0002] Steel casing placement is a crucial step in pile foundation construction. In the challenging conditions of steep coastal rock surfaces, steel casings often need to extend a certain depth into the rock. The large length of the casing makes it difficult to guarantee placement accuracy; furthermore, the considerable length affects overall stability. These are factors that urgently need to be considered during the construction of steel casings on steep coastal rock surfaces.

[0003] In summary, given the availability of existing construction platforms, there is an urgent need to propose an effective solution for improving the accuracy of steel casing placement on steep coastal rock surfaces and enhancing the overall stability between steel casings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a positioning and stabilization system for steel casings on steep coastal rock surfaces.

[0005] This coastal steep rock face steel casing positioning and stabilization system includes a steel casing, a cantilevered guide frame, steel pipe piles, and a temporary fixing frame. Several steel pipe piles are installed on the coastal land. The cantilevered guide frame is welded to the side wall of the steel pipe piles and extends outward into the water. The steel casing passes through the cantilevered guide frame and the temporary fixing frame, and the bottom of the steel casing is inserted into the steep rock face. The temporary fixing frame and the cantilevered guide frame are vertically fixedly connected.

[0006] Preferably, anchoring concrete is poured between the bottom of the steel casing and the contact surface of the steep rock face; the cantilever guide frame is provided with multiple steel casing positioning frames, and the steel casing passes through the steel casing positioning frames in the cantilever guide frame.

[0007] Preferably, a temporary fixing frame is used for reinforcing connections between several steel casings, wherein the sidewalls of the steel casings are connected to bracket supports; the bottom of the temporary fixing frame is supported on the bracket supports of the sidewalls of the steel casings.

[0008] Preferably, the temporary fixing frame is located below the cantilever guide frame, and several vertical connecting rods connect the temporary fixing frame and the cantilever guide frame.

[0009] Preferably, the steel pipe piles are connected by a horizontal bracing; I-beams and Bailey beams are arranged sequentially on the upper part of the several steel pipe piles, and a platform plate is supported on the Bailey beams.

[0010] The beneficial effects of this utility model are:

[0011] 1) This utility model connects the temporary fixing frame at the top of the steel casing to the cantilever guide frame by using a vertical connecting rod. The temporary fixing frame improves the connection strength between several steel casings and enhances the stability of the steel casing on steep rock surfaces.

[0012] 2) This utility model improves the construction efficiency of steel casings by positioning several steel casings at one time using a cantilevered guide frame welded to the side wall of the steel pipe pile.

[0013] 3) In this utility model, the bottom of the steel casing is inserted into the steep rock face, and anchoring concrete is poured at the bottom of the steel casing, which further improves the stability of the steel casing on the steep rock face. Attached Figure Description
