Description

Technical Field

[0001] The utility model relates to the technical field of Yellow River diversion gates, and more specifically, to an open Yellow River diversion gate. Background Art

[0002] Open-type Yellow River Diversion Gates are used for water conservancy operations on the Yellow River. Some older gate piers will cause foundation liquefaction problems due to long-term use. In order to ensure the safe operation of the sluice, a new Yellow River Diversion Gate will be built on the basis of some old gates that have been in use for a long time. However, this will still cause problems such as underwater pile foundations being eroded and corroded by water, which will still cause foundation liquefaction problems. Therefore, anti-seepage walls will be used to block water, but during long-term use, anti-seepage walls may penetrate, making it impossible to completely prevent foundation liquefaction problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an open Yellow River diversion sluice, which has the advantage of preventing foundation liquefaction.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an open-type Yellow River diversion gate, comprising a gate bottom plate, a bored pile is arranged at the bottom end of the gate bottom plate, a connecting pipe is placed on the top of the bored pile, a mounting groove is opened in the inner cavity of the gate bottom plate, a conical pipe is fixedly connected to the inner cavity of the mounting groove, a grouting steel pipe is fixedly connected to the top end of the conical pipe, a concrete top cover is arranged at the top end of the gate bottom plate, a stainless steel pipe cap is placed on the top end of the grouting steel pipe, the bottom end of the gate bottom plate is fixedly connected to a mounting seat, and the bottom end of the mounting seat is fixedly connected to an anti-seepage wall.

[0005] As a preferred technical solution of the utility model, the top of the stainless steel pipe cap is movably connected with a threaded ring, the inner cavity of the threaded ring is threadedly connected with a threaded rod, the bottom end of the threaded rod is movably connected with a conical plugging head, and the top of the conical plugging head is fixedly connected with a guide rod.

[0006] As a preferred technical solution of the utility model, a placement groove is opened at the center of the concrete top cover, the stainless steel pipe cap is located in the inner cavity of the placement groove, and the inner cavity of the placement groove is coated with asphalt.

[0007] As a preferred technical solution of the utility model, the gate bottom plate is the bottom of the entire gate pier, and the side of the gate bottom plate close to the anti-seepage wall is the water inlet.

[0008] As a preferred technical solution of the utility model, the bottom end of the tapered tube is located above the cast-in-place pile, and the concrete top cover is a trapezoidal body.

[0009] As a preferred technical solution of the utility model, a round hole is opened at the top of the stainless steel pipe cap, the guide rod is movably sleeved in the round hole, and the conical plugging head is fitted with the inner wall of the conical pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model embeds a conical tube in the inner cavity of the installation groove during construction, then places a stainless steel pipe cap on the top of the conical tube, and builds a concrete top cover on the top of the gate bottom plate to protect the stainless steel pipe cap. When the bored pile liquefies, the concrete top cover is broken and opened, and then the stainless steel pipe cap is picked up, and then the external grouting equipment is used to input the material into the bored pile along the grouting steel pipe, so as to construct the bored pile, thereby realizing that by pre-embedding the grouting steel pipe, grouting can be carried out when the bored pile liquefies in the later stage, thereby avoiding the bored pile liquefaction and the gate pier being unusable.

[0012] 2. The utility model blocks the bored pile by inserting the conical plugging head into the inner cavity of the conical tube when placing the stainless steel tube cap, thereby preventing the bored pile from becoming loose and moving toward the inner cavity of the grouting steel tube under external pressure when the bored pile is liquefied, causing the entire grouting steel tube to be blocked. After grouting with the grouting steel tube is completed, the threaded ring is rotated to drive the conical plugging head to move along the axial direction of the threaded rod and the guide rod to scrape off the slurry damaged on the inner wall of the grouting steel tube, thereby preventing the slurry damaged on the inner wall of the grouting steel tube from being unusable.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides an open-type Yellow River diversion gate, including a gate bottom plate 1, a cast-in-place pile 2 is arranged at the bottom end of the gate bottom plate 1, a connecting pipe 3 is placed on the top of the cast-in-place pile 2, a mounting groove 4 is opened in the inner cavity of the gate bottom plate 1, a tapered pipe 5 is fixedly connected to the inner cavity of the mounting groove 4, a grouting steel pipe 6 is fixedly connected to the top of the tapered pipe 5, a concrete top cover 7 is arranged at the top of the gate bottom plate 1, a stainless steel pipe cap 8 is placed on the top of the grouting steel pipe 6, a mounting seat 9 is fixedly connected to the bottom end of the gate bottom plate 1, and an anti-seepage wall 10 is fixedly connected to the bottom end of the mounting seat 9;

[0021] During construction, the conical tube 5 is pre-buried in the inner cavity of the installation groove 4, and then the stainless steel pipe cap 8 is placed on the top of the conical tube 5, and a concrete top cover 7 is built on the top of the gate bottom plate 1 to protect the stainless steel pipe cap 8. When the bored pile 2 liquefies, the concrete top cover 7 is broken and opened, and then the stainless steel pipe cap 8 is picked up, and then the external grouting equipment is used to input the material into the bored pile 2 along the grouting steel pipe 6, so as to construct the bored pile 2, thereby realizing that by pre-buried grouting steel pipe 6, grouting can be carried out when the bored pile 2 liquefies in the later stage, thereby avoiding the bored pile 2 liquefaction and the gate pier being unusable.

[0022] The top of the stainless steel pipe cap 8 is movably connected to a threaded ring 11, the inner cavity of the threaded ring 11 is threadedly connected to a threaded rod 12, the bottom end of the threaded rod 12 is movably connected to a conical plug 13, and the top end of the conical plug 13 is fixedly connected to a guide rod 14;

[0023] By inserting the conical plugging head 13 into the inner cavity of the conical tube 5 when placing the stainless steel pipe cap 8, the bored pile 2 is blocked, thereby preventing the bored pile 2 from becoming loose and moving toward the inner cavity of the grouting steel pipe 6 under external pressure when the bored pile 2 is liquefied, causing the grouting steel pipe 6 to be blocked as a whole. After grouting is completed using the grouting steel pipe 6, the threaded ring 11 is rotated to drive the conical plugging head 13 to move along the axial direction of the threaded rod 12 and the guide rod 14 to scrape off the slurry damaged on the inner wall of the grouting steel pipe 6, thereby preventing the slurry damaged on the inner wall of the grouting steel pipe 6 from being unusable.

[0024] A placement groove is provided at the center of the concrete top cover 7, a stainless steel pipe cap 8 is located in the inner cavity of the placement groove, and the inner cavity of the placement groove is coated with asphalt;

[0025] By setting the placement groove, the stainless steel pipe cap 8 can be located in the inner cavity of the placement groove, thereby avoiding direct contact between the concrete top cover 7 and the stainless steel pipe cap 8, which would cause adhesion between the stainless steel pipe cap 8 and the concrete top cover 7.

[0026] The gate bottom plate 1 is the bottom of the entire gate pier, and the side of the gate bottom plate 1 close to the anti-seepage wall 10 is the water inlet;

[0027] The gate bottom plate 1 is the bottom of the entire gate pier, so that the gate bottom plate 1 supports the entire gate pier, and the side of the gate bottom plate 1 close to the anti-seepage wall 10 is the water inlet, so that the anti-seepage wall 10 can block the water under the ground and prevent water from penetrating and scouring the cast-in-place piles 2.

[0028] The bottom end of the tapered tube 5 is located above the cast-in-place pile 2, and the concrete top cover 7 is a trapezoidal body;

[0029] The bottom end of the tapered tube 5 is located above the bored pile 2, so that the slurry can be injected into the bored pile 2 through the tapered tube 5. The concrete top cover 7 is a trapezoidal body, so that when the top of the gate bottom plate 1 passes through the water flow, the water flow can flow along the top of the concrete top cover 7, thereby reducing the impact force of the water on the concrete top cover 7.

[0030] The top of the stainless steel pipe cap 8 is provided with a round hole, the guide rod 14 is movably sleeved in the round hole, and the conical plug 13 is fitted with the inner wall of the conical pipe 5;

[0031] The guide rod 14 is limited by the circular hole at the top of the stainless steel pipe cap 8, so that when the threaded ring 11 rotates to drive the threaded rod 12 to move, the conical plugging head 13 will not rotate due to the limitation of the guide rod 14, so that the conical plugging head 13 can move along the axial direction of the guide rod 14, thereby improving the stability during movement, and then the conical plugging head 13 fits with the inner wall of the conical tube 5, thereby preventing the liquefied cast-in-place pile 2 from entering the inner cavity of the conical tube 5, resulting in blockage of the top of the grouting steel pipe 6.

[0032] The working principle and use process of the utility model are as follows: the gate bottom plate 1 and the bored pile 2 are located underground, and the grouting steel pipe 6 is pre-buried in the inner cavity of the installation groove 4, so that the bottom end of the tapered pipe 5 is located above the bored pile 2, and then the side of the gate bottom plate 1 close to the anti-seepage wall 10 is the water inlet, and then the water is blocked by the anti-seepage wall 10. When the anti-seepage wall 10 is used for a long time and seepage occurs, the water washes the bored pile 2, or the bored pile 2 is corroded when it is located underground;

[0033] When the bored pile 2 is liquefied, the concrete top cover 7 is smashed and opened, and then the staff rotates the threaded ring 11 to rotate, and the threaded rod 12 meshing with it is driven to move by the rotation of the threaded ring 11, thereby driving the conical plug 13 to move along the axis direction of the threaded rod 12 and the guide rod 14, so that the conical plug 13 rises, and when the conical plug 13 rises to the top, the stainless steel pipe cap 8 and the conical plug 13 are taken away from the top of the grouting steel pipe 6, and then the external grouting equipment is used to grout the bored pile 2 through the grouting steel pipe 6, and the material can enter the interior of each bored pile 2 along the connecting pipe 3 through the connecting pipe 3, and the liquefied bored pile 2 is repaired by grouting;

[0034] When grouting is completed, the stainless steel pipe cap 8 is placed on the top of the grouting steel pipe 6 again, and the threaded ring 11 is rotated to drive the threaded rod 12 to move, thereby driving the conical plugging head 13 to move along the axial direction of the threaded rod 12 and the guide rod 14 to the inner cavity of the conical tube 5 to block and scrape the material.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
