[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering projects, concrete and other materials are poured into a mold to form a predetermined shape. At present, for soil layers with geological conditions such as general fill layers, silt layers, thin sandy soil layers and general non-self-weight subsidence loess layers, the spiral drilling pumping concrete pouring pile method is generally preferred in pile foundation design and construction. That is, the mixed concrete slurry is poured in the pile hole, and a steel cage is inserted. After routine maintenance, the pile foundation construction is completed. At this stage, the pouring external call device often has water seepage, which can easily reduce the quality of the poured piles.

[0028] The working principle of the concrete pouring enclosure structure provided by the utility model is as follows:
[0029] When in use, first drill a hole vertically downward on the foundation, then drive the outer protective tube 1 into the inner wall of the pile hole, so that the outer protective tube 1 is supported on the inner wall of the pile pit to prevent the entry of external groundwater and soil debris generated by the collapse of the pit wall, which can improve the quality of the poured piles, make the top of the outer protective tube 1 level with the ground, and then cover the inlet shield 21 from the top of the outer protective tube 1, make one end surface of the bracket 23 contact the bottom surface of the side rib 22 fixed on the top side wall of the inlet shield 21, adjust its position so that the through hole set at one end of the bracket 23 corresponds to the through hole set on the side rib 22, and then pass the The positioning pin penetrates them in series, that is, the bottom end of the bracket 23 is flush with the bottom surface of the limit stop ring 25, so that the bottom end of the inlet shield 21 goes deep into the foundation along the side wall of the outer protective tube 1, so that the top of the outer protective tube 1 touches the bottom surface of the limit stop ring 25, and the other end of the bracket 23 touches the bottom surface, so as to firmly support the inlet shield 21, and then the end of the positioning tube 31 with a small opening is placed downward from the top of the inlet shield 21, so that the threaded telescopic rod 33 is placed on the top surface of the inlet shield 21, and then the position of the baffle 34 is adjusted to make it flush with the side wall of the edge 22. The positioning tube 31 is then adjusted to be at the center of the top end of the inlet shield 21, and the thicker end of the threaded telescopic rod 33 is rotated to fix the position of the other end, so that the threaded telescopic rod 33 can be driven to retract until the baffle 34 abuts against the side wall of the edge rib 22, so that the baffle 34 limits the position of the positioning tube 31 under the pulling of the threaded telescopic rod 33. When the threaded telescopic rod 33 is rotated, the position of the positioning tube 31 is kept unchanged, and then the guide tube 51 is inserted from the top end of the positioning tube 31, so that the guide tube 51 is located between the limiting edge block 52 and The oblique stopper 32 is engaged with the inside of the positioning tube 31 under the interference, so that the guide tube 51 is located at the center position inside the outer protective tube 1, and then the bottom end of the feed hopper 41 is inserted into the inside of the top end of the positioning tube 31, so that the support foot 42 fixed along the side wall is supported on the surface of the bottom end of the bracket 23, so that the position of the feed hopper 41 is limited, and at the same time, the feed hopper 41 and the inlet shield 21 can be connected together, so that the position of the bracket 23 is further limited and supported. This structure has the advantage of being able to effectively protect the outer ring from water seepage and soil debris entering the casting circle when pouring concrete for the pile foundation.

The bracket 23 supports and positions the inlet enclosure structure 2. Then, place the positioning structure 3 inside the top end of the inlet enclosure structure 2 and adjust its position to make it at the center of the opening at the top end of the inlet enclosure structure 2. Then, rotate the threaded telescopic rod 33 to cooperate with the baffle 34 to clamp it at the center of the opening inside the top end of the inlet enclosure structure 2. Then, insert the guiding structure 5 from the top end of the positioning structure 3 and make its top end snap into the positioning structure 3.
