Abstract
Description
Technical Field
[0001] The utility model relates to a steel cage protection structure for a concrete pile, in particular to a steel cage protection structure for over-pouring of a concrete pile. Background Art
[0002] When making concrete piles, in order to ensure the concrete strength of the top of the concrete piles and the quality of the project, in the actual construction process of concrete piles, over-pouring is required to achieve the floating of floating objects mixed in the concrete, debris that has not been cleaned up in the foundation pit, silt at the bottom of the hole that is difficult to completely remove in the foundation pit, and bubbles mixed in the concrete. The over-pouring part is the part mixed with these impurities; after the concrete piles solidify, the over-pouring part of the concrete needs to be removed. The common method is to use a hammer to make this part of the concrete fall off, and then clean the remaining concrete on the steel cage while ensuring that the steel cage is not excessively deformed. This approach not only requires a lot of manpower and material resources, but also seriously affects the progress of the project. Utility Model Content

DETAILED DESCRIPTION
[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so as to more clearly understand the invention objectives, features and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to explain that the technical solution of the present invention is not limited to one implementation method.
[0018] Combined with Figures 1 to 4The steel cage protection structure for over-pouring of concrete piles comprises a protection tube and an anti-overflow tube 9, the anti-overflow tube 9 is sleeved on the outside of the protection tube, two handles 8 are arranged opposite to each other on the upper part of the outer wall of the anti-overflow tube 9, an annular cavity 15 is formed between the anti-overflow tube 9 and the protection tube, the protection tube comprises an outer tube 7, an outer tube cavity 19 is arranged in the outer tube 7, an inner tube 6 is arranged in the outer tube cavity 19, an inner tube cavity 10 is arranged in the inner tube 6, an annular plate 4 is arranged between the top of the outer tube 7 and the top of the inner tube 6, two hanging rings 1 and two through holes 18 are arranged on the annular plate 4 at intervals, a cover 3 is arranged at the top of the two through holes 18, a handle 2 is arranged at the top of the cover 3, a rubber plug 5 is arranged at the bottom of the cover 3, the rubber plug 5 is inserted in the through hole 18, a foaming material 11 is arranged between the bottom of the outer tube 7 and the bottom of the inner tube 6, and the foaming material 11 is a thermal insulation foaming agent.
[0019] The steel cage protection structure for overfilling concrete piles is implemented in combination with the attached Figures 1 to 5 The specific construction of the present disclosure is further explained; after the steel cage 13 is placed in the excavated foundation pit, the steel cage 13 is positioned so that the steel cage 13 is centered in the foundation pit 17, and the protective tube and the outer anti-overflow tube 9 are soaked or sprayed in all directions with a cement release agent, and then the protective tube is covered on the top of the steel cage 13 using the outer tube cavity 19 between the outer tube 7 and the inner tube 6, so that the top of the steel cage 13 is in contact with the bottom of the ring plate 4, and the inner tube 6 is placed in the cage cavity 14 provided in the steel cage 13, and the foaming material 11 is sprayed at the lower opening between the inner tube 6 and the outer tube 7 for sealing, and the sealing of the foaming material 11 plays a role in fixing the protective tube on the top of the steel cage 13. The anti-overflow tube 9 is placed on the pit mouth of the foundation pit 17 of the base surface 12, so that the lower part of the outer wall of the anti-overflow tube 9 is in contact with the soil layer 16, and the inner tube cavity 10 is used to form a pouring channel to pour concrete into the steel cage 13. After the concrete solidifies, the cover 3 is removed. At this time, the outer tube cavity 19 between the outer tube 7 and the inner tube 6 is connected to the external environment. The protective tube loses negative pressure and can be removed by lifting the lifting ring 1 through the lifting device (although the foaming material 11 has a certain strength, it is insignificant compared with the weight of the steel cage 13 after the concrete is poured, and the cement release agent also has a lubricating effect). Then the anti-overflow tube 9 is removed to form a combined attachment Figure 5 The structure is as follows: the steel cage 13 in the foundation pit 17 forms a concrete pile 23, the concrete located inside the inner cylinder cavity 10 forms a concrete super-filling column 21, the annular cavity 15 between the anti-overflow cylinder 9 and the protection cylinder forms a concrete shell 22, and the space between the concrete super-filling column 21 and the concrete shell 22 forms a gap 20. Use tools to smash the concrete shell 22 and the concrete super-filling column 21 on the upper part of the concrete pile 23, and remove the foaming material 11 at the lower part of the gap 20.
