Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile foundation engineering, in particular to a double-row anti-slip structure of steel tube concrete mixing composite piles. Background Art
[0002] At present, the anti-slip piles used in slope landslides are mainly bored piles or manually excavated piles. Bored piles are prone to collapse in the landslide soil, and the retaining mud can easily seep into the landslide line, which may have an adverse effect on the landslide stress. Manually excavated pile holes in the landslide body are risky. At the same time, the construction period of both types of anti-slip piles is relatively long, which makes it difficult to cope with rapidly developing landslides. Summary of the Invention
[0003] The purpose of this utility model is to provide a double-row anti-slip structure of steel tube concrete mixing composite piles based on the above-mentioned deficiencies in the existing technology. It does not require excavation of pile holes, and there is no influence of hole collapse and mud. After adopting the combined structure of double-row piles and crown beams, a gate-type anti-slip pile structure is formed, which effectively improves the anti-slip ability and realizes slope reinforcement.
[0004] The purpose of this utility model is achieved by the following technical solutions:
[0005] A double-row anti-slip structure of steel tube concrete mixing composite piles is characterized by comprising two rows of parallel arranged steel tube concrete mixing composite piles, wherein the two rows of steel tube concrete mixing composite piles are connected and fixed by a reinforced concrete crown beam arranged on the top to form a gate-type anti-slip pile row structure arranged at a slope landslide location; the steel tube concrete mixing composite piles comprise cement soil and a steel pipe arranged in the cement soil, and the interior of the steel pipe is poured with concrete.
[0006] The gate-type anti-slip pile structure is arranged at the foot of the slope, that is, outside the landslide position of the slope.
[0007] The gate-type anti-slip pile structure is arranged in the middle of the slope.
[0008] A connecting steel cage is provided on the top of the steel pipe, and the connecting steel cage is connected to the steel cage in the reinforced concrete crown beam.
[0009] The advantages of the utility model are:
[0010] 1) In steel tube concrete mixing composite piles, there is no need to excavate pile holes, there is no impact of hole collapse and mud, and the impact on landslides is small;
[0011] 2) Steel tube concrete mixing composite pile construction machinery is short, and construction is fast and convenient;
[0012] 3) The reinforced concrete cap beam cast on the double-row piles is rigidly connected to the composite piles to form a portal-type anti-slip pile structure with strong ability to resist landslide thrust. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is the plan layout diagram of the present utility model;
[0015] Figure 3 This is a structural diagram of embodiment 2 of the present utility model. DETAILED DESCRIPTION
[0016] 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:
[0017] like Figure 1-3 As shown, marks 1-3 in the figure respectively represent: steel tube concrete mixing composite pile 1, reinforced concrete crown beam 2, and slope landslide 3.
[0018] Example 1: Figure 1 and Figure 2 As shown, the double-row anti-slip structure of steel tube concrete mixing composite piles in this embodiment includes two rows of steel tube concrete mixing composite piles 1, front and rear, extending outward along the slope. Each row of steel tube concrete mixing composite piles 1 includes a plurality of steel tube concrete mixing composite piles 1 arranged longitudinally along the slope. Each steel tube concrete mixing composite pile 1 comprises cement soil and a steel pipe disposed within the cement soil, the steel pipe being poured with concrete.
[0019] like Figure 1 As shown, the front and rear rows of steel tube concrete mixing composite piles 1 are connected and fixed by setting a reinforced concrete crown beam 2 on the top to form a gate-type anti-slip pile structure set at the bottom of the slope landslide 3 to resist the landslide thrust.
[0020] In this embodiment, a connecting steel cage is provided at the top of the steel tube, which is connected to the steel cage in the reinforced concrete crown beam 2, thereby improving the connection performance and integrity between the steel tube concrete mixing composite pile 1 and the reinforced concrete crown beam 2, and further improving its anti-slip effect.
[0021] Example 2: Figure 3 As shown, this embodiment differs from the first embodiment in that the steel tube concrete mixing composite piles 1 and reinforced concrete cap beams 2 are located in the middle of the landslide 3. If a landslide occurs on the excavated slope, a construction platform can be set up in the middle of the landslide to quickly construct two rows of steel tube concrete mixing composite piles. Reinforced concrete cap beams are cast on the two rows of piles and rigidly connected to the composite piles, forming a portal-type anti-slip pile structure to resist the thrust of the landslide.
[0022] The above embodiment includes the following construction methods during construction:
[0023] 1) The rotary power head holds the steel pipe and rotates, driving the bottom mixing head to rotate. The mixing head cuts the soil. At the same time, the cement slurry pump sprays cement slurry to the mixing head through the grouting hose and grouting steel pipe. The pile head soil is fully mixed with the cement slurry under the stirring of the mixing head to form a large cement-soil pile. At the same time, the frame drives the steel pipe and the mixing head to sink while stirring in the soil. If re-mixing is required, the frame can also drive the steel pipe and the mixing head to stir up and down to complete the re-mixing.
[0024] 2) Construct two rows of steel pipe piles according to the first step, pour concrete into the two rows of steel pipe piles, and set connecting steel cages on the top of the piles.
[0025] 3) Connect the connecting steel cage at the top of the steel pipe to the steel cage in the reinforced concrete crown beam 2. Cast the reinforced concrete crown beam structure on the top of the pile to form a portal anti-slip pile structure.
[0026] This embodiment can quickly and effectively form an anti-slip structure and can be widely used in rapid remediation projects for various types of soil landslides.
[0027] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, it is recognized by those skilled in the art that various improvements and modifications may be made to the present invention without departing from the scope of the claims, and therefore they will not be described in detail here.
