Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation engineering, in particular to a steel pipe mortar or cement slurry mixing composite pile. Background Art

[0002] At present, in steel tube concrete mixing composite piles, the material poured into the steel tube is mainly concrete; however, when the diameter of the steel tube is small, it may be difficult to pour concrete into the steel tube. Summary of the Invention

[0003] The purpose of this utility model is to provide a steel pipe mortar or cement slurry mixed composite pile based on the above-mentioned deficiencies in the existing technology. The mortar or cement slurry is poured to ensure that the internal filling material is effectively poured into the steel pipe when the diameter is small. At the same time, the bearing capacity of the mixed composite pile is also effectively controlled, which is suitable for the reinforcement of structures with smaller loads.

[0004] The purpose of this utility model is achieved by the following technical solutions:

[0005] A steel pipe mortar or cement slurry mixing composite pile, characterized in that it comprises a steel pipe and cement soil, the steel pipe is inserted into the cement soil and the two are combined to form a mixing composite pile, and the interior of the steel pipe is poured with mortar or cement slurry.

[0006] The outer wall of the steel pipe is provided with ribs, and the ribs are evenly spaced along the length direction of the steel pipe.

[0007] The ribs are symmetrically arranged along the circumference of the steel pipe.

[0008] A stirring head is provided at the bottom of the steel pipe.

[0009] The advantages of the utility model are:

[0010] 1) When the diameter of the steel pipe is small, it can ensure high-quality filling inside;

[0011] 2) It can be widely used in various support and isolation projects with relatively low bearing capacity requirements, small steel pipes, narrow construction sites, low clearance, proximity to existing structures, and sensitive surrounding environments;

[0012] 3) The structure is simple and reasonable, the construction is convenient, and it is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0014] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0015] like Figure 1 As shown in the figure, marks 1-4 respectively represent: cement soil 1, steel pipe 2, mortar or cement slurry 3, and rib plate 4.

[0016] Example: Figure 1 As shown, the small-diameter mixed composite pile in this embodiment comprises a cement-soil 1, which is constructed using a mixing pile construction method. A steel pipe 2 is inserted within the cement-soil 1, serving as a reinforcement within the cement-soil 1 and forming the mixed composite pile together with the cement-soil 1. In this embodiment, a small-diameter mixed composite pile primarily refers to a situation where the diameter of the steel pipe 2 is relatively small, particularly when the interior is insufficient for concrete pouring.

[0017] In this embodiment, mortar or cement slurry 3 is poured into the interior of the steel tube 2, filling and sealing the interior of the steel tube 2, thereby enriching the interior. Because the mortar or cement slurry 3 generally has greater fluidity than concrete, it satisfies the requirements for filling the interior of a steel tube 2 with a smaller diameter. Furthermore, and more importantly, by selecting mortar or cement slurry 3 as the filler within the steel tube 2, the overall bearing capacity of the mixed composite pile can be effectively improved, particularly when reinforcing structures with relatively low loads and relatively low bearing capacity requirements.

[0018] like Figure 1 As shown, a number of ribs 4 are provided on the outer wall of the steel pipe 2. On the one hand, the ribs 4 are used to increase the connection performance between the steel pipe 2 and the cement soil 1, that is, to ensure the integrity between the steel pipe 2 and the cement soil 1, thereby ensuring the structural performance of the mixing composite pile; on the other hand, the ribs 4 can also play a role in stirring the cement soil 1 during the rotation and insertion process of the steel pipe 2, thereby ensuring the construction quality of the cement soil 1 for a second time.

[0019] In this embodiment, the ribs 4 are evenly arranged along the height direction of the steel pipe 2 to evenly improve the connection performance between the steel pipe 2 and the cement soil 1; at the same time, the ribs 4 can also be evenly arranged around the circumference of the steel pipe 2.

[0020] During the specific implementation of this embodiment: a mixing head is provided at the bottom of the steel pipe 2 , and the mixing head is used for mixing the cement soil 1 .

[0021] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described here one by one.
