Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a civil engineering hollow pile which is convenient for drainage. Background Art

[0002] Hollow piles are hollow cylindrical, slender concrete precast components manufactured in civil engineering using a prestressing process and centrifugal forming method. However, existing hollow piles still have shortcomings. Specifically, when existing hollow piles are in use, pore water seeping from the soil around the pile body forms a water film at the pile-soil critical interface, making it impossible for the pile body and the surrounding soil to form sufficiently effective pile side friction resistance, affecting the stability of the hollow pile.

[0003] Therefore, a civil engineering hollow pile that is convenient for drainage is needed to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a civil engineering hollow pile that is convenient for drainage, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A hollow pile for civil engineering with convenient drainage comprises a hollow pile body, an outer wall of the hollow pile body is provided with a drainage mechanism, and the interior of the hollow pile body is fixedly connected to a support frame;

[0007] The drainage mechanism includes a protective cover fixed to the outer wall of the hollow pile body, an annular groove is provided on the inner wall of the protective cover, a diversion hole is provided on the inner wall of the annular groove and on the side away from the hollow pile body, an absorption pad is slidably connected to the inside of the annular groove and near the diversion hole, a connecting rubber strip is fixedly connected to the inside of the annular groove and near the absorption pad, a baffle is slidably connected to the inside of the protective cover and near the diversion hole, a pull ring is fixedly connected to the top of the baffle and above the protective cover, and a friction pad is fixedly connected to the outer wall of the protective cover.

[0008] As a preferred solution of the present invention, the hollow pile body is made of cast concrete, and the support frames are provided in multiple groups, and the support frames are made of stainless steel.

[0009] As a preferred solution of the present invention, the protective cover and the baffle are both made of ABS plastic, the diversion holes are provided in multiple groups, and the baffle passes through and extends outside the protective cover.

[0010] As a preferred solution of the present invention, the absorption pad is made of water-absorbing resin, the guide hole is arranged obliquely outside the annular groove, and the baffle is connected to the absorption pad by sliding connection.

[0011] As a preferred solution of the present invention, the friction pad is made of anti-slip rubber, and the shapes of the friction pad and the baffle are both annular structures.

[0012] As a preferred solution of the present invention, four groups of pull rings are provided, and the shape of the protective cover is adapted to the shape of the hollow pile body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The invention relates to a hollow pile for civil engineering which is convenient for drainage. The drainage mechanism in the device is used to remove the pore water which seeps around the hollow pile body. When the pull ring is pulled, the pull ring will drive the baffle to move upward. The baffle which moves upward will exit the protective cover. The baffle no longer seals the absorption pad, and the hollow pile body is inserted into the soil. The friction pad on the outer wall of the hollow pile body can increase the friction between the soil and the hollow pile body. At the same time, the pore water in the soil flows into the annular groove in the protective cover through the diversion hole. The absorption pad made of absorbent resin can absorb the inflowing pore water, thereby reducing the amount of pore water around the hollow pile body and further improving the friction between the soil and the hollow pile body. The invention solves the problem that when the existing hollow pile is in use, the pore water seeping from the soil around the pile body will form a water film at the pile-soil critical surface, so that the pile body and the surrounding soil cannot form a sufficiently effective pile side friction resistance, thereby affecting the stability of the hollow pile.
