Description

Technical Field

[0001] The utility model relates to the technical field of engineering composite piles, and more specifically, to a civil engineering composite pile. Background Art

[0002] Composite piles in civil engineering are an important part of the operation of housing construction sites. According to the relative ratio of the side friction resistance and end resistance provided by the soil, engineering piles can be divided into four categories: friction piles, end-bearing piles, end-bearing friction piles and friction end-bearing piles. According to the size of the pile diameter, the piles can be divided into three categories: large-diameter piles, medium-diameter piles and small-diameter piles. According to the pile body material, the piles can be divided into concrete piles, wooden piles, steel piles and composite piles. According to the different pile-forming methods, they can be divided into three types: soil-squeezing piles (such as driven precast piles), partially soil-squeezing piles (such as pre-drilled and driven precast piles) and non-squeezing piles (such as bored and cast-in-place piles). According to the construction method, the piles can be divided into two categories: precast piles and cast-in-place piles.

[0003] Currently, most composite piles are designed in multiple sections in order to be transported and driven into the ground. However, after the pile pipes are inserted into the ground, the connection between the pile pipes is poor. At the same time, no reinforcement measures are designed between the pile pipes and the soil, resulting in poor stability. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a civil engineering composite pile, which has the characteristics of improving the pile-pipe connection effect and better stability.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides a civil engineering composite pile, including a first pile pipe, a ring groove is provided on the top of the first pile pipe, a ring block is clamped in the ring groove, a second pile pipe is fixedly connected to the top of the ring block, four slots are provided in the ring groove, four fixing rods are inserted in the four slots, and the tops of the four fixing rods are fixedly connected to the bottom of the ring block, an annular through groove is provided in the first pile pipe, one end of the four slots is communicated with the top of the annular through groove, two groups of through holes are provided on the outside of the first pile pipe, fixing nails are inserted in the two groups of through holes, one end of the two groups of fixing nails are fixedly connected with arc plates, springs are sleeved on the outside of the two groups of fixing nails, one end of the two groups of springs are fixedly connected to the inner wall of the first pile pipe, and the other ends of the two groups of springs are respectively fixedly connected to one side of the two groups of arc plates, and a conical pipe is fixedly connected to the inside of the second pile pipe through a plurality of support rods.

[0008] When a civil engineering composite pile of the present technical solution is used, by setting the slot, the fixing rod and the annular groove, concrete can be injected into it after the connection is completed, so that it enters the annular groove and solidifies, thereby improving the connection effect between the first pile pipe and the second pile pipe.

[0012] Furthermore, the outer side of the conical tube overlaps with the other side of the two groups of arc plates.

[0013] (3) Beneficial effects

[0014] In summary, the utility model has the following beneficial effects:
