Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile foundation construction, in particular to pile foundation hole construction equipment. Background Art
[0002] During the pile foundation construction process, it is necessary to first use a rotating drill to create holes in the rock and soil layer to facilitate pile foundation construction. Before drilling construction, a geological survey must be conducted first to understand the composition and properties of the stratum in order to reasonably select the drilling method and process. Based on the results of the geological survey, a drilling design can be carried out. The drilling design includes determining parameters such as the pile diameter, hole depth, and drilling straightness, which will facilitate the subsequent selection of appropriate drilling machinery and debugging.
[0003] After the drilling of the pile foundation hole is completed, the pipe needs to be inserted into the hole, and then a steel cage is placed in the pipe and concrete is poured to form a pile foundation. During the process of inserting the pipe, a lifting device is needed to lift the pipe and insert it vertically into the hole. However, when the lifting device lifts the upper end of the pipe, it is connected with a wire rope. The pipe will shake during the process of being placed in the hole, which will cause the pipe to be placed in an inaccurate position or get stuck during the placement process. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] like Figure 1 , Figure 2 and Figure 3As shown, a pile foundation hole construction equipment includes an annular bottom plate 8 and at least one and evenly arranged guide structure 1, the lower end of the annular bottom plate 8 is adhered with a spacer, the spacer can prevent the bottom surface of the annular bottom plate 8 from being worn during use, the annular bottom plate 8 is fixedly connected to the ground around the hole mouth, both sides of the annular bottom plate 8 are fixedly connected with mounting plates 9, the mounting plates 9 are provided with mounting holes 10, the mounting holes 10 are connected to the ground with expansion bolts, and the upper end of the annular bottom plate 8 is fixedly connected with oppositely arranged vertical poles 11.
[0022] Through the above structure, the annular bottom plate 8 is installed around the orifice to guide the pipeline. The specific structure is as follows:
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the guide structure 1 includes an annular outer plate 2, and side blocks 6 are fixedly connected on both sides of the annular outer plate 2. Through holes 7 cooperating with the vertical poles 11 are provided on the side blocks 6 on both sides. At least one and evenly arranged connecting plates 3 are provided in the annular outer plate 2, and an annular inner plate 4 is fixedly connected in the connecting plate 3. The annular inner plate 4 cooperates with the pipeline, and reinforcing round steel bars 5 are fixedly connected to the connecting plate 3. The reinforcing round steel bars 5 penetrate through the connecting plates 3 arranged in an annular manner, which can improve the stability of the guide structure 1.
[0024] Through the above structure, the pipe is placed into the hole along the inner cavity of the annular inner plate 4, which can avoid the pipe being placed in an inaccurate position or getting stuck due to tilting.
[0025] Embodiment 2
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the upper ends of the vertical rods 11 are threadedly connected with top plugs 12 that cooperate with the side blocks 6.
[0027] Through the above structure, the top plug 12 can block the upper end of the vertical rod 11.
[0028] When the utility model is implemented, after the drilling is completed, a pipe needs to be placed therein. The length of the pipe is determined by the depth of the drilling. After selecting the pipe of appropriate length, the height of the stacking guide structure is selected according to the length of the pipe. Specifically, the annular bottom plate is first placed around the hole, and after adjusting the position, the installation hole is fixedly connected to the ground with expansion bolts, and the installation plate can be fixed on the ground.
[0029] Then the guiding structure can be inserted into the vertical poles on both sides. Specifically, the through holes on the side blocks on both sides of the annular outer plate are respectively aligned with the vertical poles on both sides, and then the side blocks are moved down along the vertical poles, and finally a suitable number of annular outer plates are inserted. At this time, the annular inner plate can form a channel for guiding the pipeline. Use a lifting device to lift one end of the pipeline and insert it into the area surrounded by the annular inner plate. The annular inner plate can be used to guide the pipeline to ensure that the pipeline is in a vertical state above the orifice, thereby avoiding the situation where the pipeline is placed in an inaccurate position or gets stuck due to tilting.
