Description

Technical Field

[0001] The present application relates to the technical field of bridge pier construction, and in particular to a super-high pier concrete pump pipe installation structure. Background Art

[0002] As my country's bridge construction level continues to improve, super-high pier and large-section structural bridges continue to emerge, and super-high pumped concrete has been widely used. As the construction height continues to increase, the height of concrete pumping has also continued to increase, and the pumping height can even reach 200 meters.

[0003] In the prior art, during the construction of such super-high piers, a pump pipe is used to pump concrete, and the pump pipe is installed through a mounting bracket arranged on one side of the super-high pier. Such mounting bracket rises with the increase of the height of the super-high pier. When the height is too large, the load-bearing capacity of the steel pipe at the bottom of the bracket is close to the limit, and bending deformation is likely to occur, thereby causing the risk of collapse of the entire bracket. In addition, the construction of the bracket is time-consuming and labor-intensive. After the construction is completed, the pump pipe must be installed on the bracket again. The operation is complicated and inefficient, which greatly prolongs the construction period.

[0004] Therefore, the inventor needs to design a new super-high pier concrete pump pipe installation structure to overcome the above problems. Summary of the invention

[0005] The main purpose of the present application is to provide a super-high pier concrete pump pipe installation structure to solve the problems of easy collapse and low installation efficiency of the pump pipe support in the related art.

[0006] In order to achieve the above-mentioned purpose, the present application provides an ultra-high pier concrete pump pipe installation structure, including a connecting plate fixedly connected to two embedded bolts at the same height, one end of a plurality of pressure plates being rotatably arranged on the connecting plate, and a connecting structure being fixedly arranged between the other end of the pressure plate and the connecting plate; and also including a plurality of pump pipe assemblies, the pump pipe assemblies including a plurality of steel pipes connected end to end, the steel pipes being fixedly arranged between the pressure plate and the connecting plate, and a load-bearing structure being also arranged between the steel pipes and the connecting plate.

[0007] Preferably, a rotation groove is opened on the front side of the connecting plate, a rotation pin is fixedly arranged in the rotation groove, connecting arms are fixedly arranged at both ends of the pressure plate, both connecting arms are located in the rotation groove, and one of the connecting arms is rotationally connected to the rotation pin.

[0008] Preferably, the connection structure comprises a screw rod, which passes through the connection plate and the other connection arm and is fixedly connected via a first nut.

[0009] Preferably, the connecting plate is sleeved on the outside of the embedded bolts, and a second nut is threadedly connected to the embedded bolts, and the second nut presses the connecting plate against the outer wall of the super-high pier.

[0010] Preferably, the connecting plate is provided with an arc-shaped groove matched with the outer wall of the steel pipe, and the pressing plate is an arc-shaped plate matched with the steel pipe.

[0011] Preferably, two adjacent steel pipes are fixedly connected by threads.

[0012] Preferably, the load-bearing structure is a load-bearing ring, which is fixedly arranged on the outer wall of the steel pipe, and the bottom of the load-bearing ring is in contact with the top of the connecting plate.

[0013] Preferably, the spacing between the load-bearing rings on two adjacent steel pipes is equal to the spacing between several layers of embedded bolts.

[0014] Preferably, the top of the pressing plate and the top of the connecting plate are in the same horizontal plane, and the bottom of the load-bearing ring is in contact with the top of the pressing plate.

[0015] The utility model provides a super-high pier concrete pump pipe installation structure, which has the following beneficial effects compared with the prior art:

[0016] The installation of the pump pipe is achieved by setting a connecting plate on the embedded bolts of the super-high pier and then pressing each section of the steel pipe of the pump pipe onto the limiting connecting plate through a pressure plate. The gravity of each section of the steel pipe is then transferred to the connecting plate through the load-bearing structure, and then to the embedded bolts, so that the force on the bottom steel pipe is smaller and the pump pipe is not easy to collapse. At the same time, the installation structure of the connecting plate is simple and not prone to collapse. The connecting plate of each layer of steel pipe is installed separately, and the installation speed is fast and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 3 As shown, a super-high pier concrete pump pipe installation structure includes a connecting plate 2 fixedly connected to two embedded bolts 1 at the same height, one end of a plurality of pressing plates 3 is rotatably arranged on the connecting plate 2, and a connecting structure is fixedly arranged between the other end of the pressing plate 3 and the connecting plate 2; it also includes a plurality of pump pipe assemblies, and the pump pipe assemblies include a plurality of steel pipes 4 connected end to end, the steel pipes 4 are fixedly arranged between the pressing plates 3 and the connecting plates 2, and a load-bearing structure is also arranged between the steel pipes 4 and the connecting plates 2; during operation, in the process of raising the super-high pier layer by layer, embedded bolts 1 are evenly arranged on the outside of the super-high pier, and these embedded bolts 1 can provide a safe fixing point , used to fix equipment or accessories on the bridge, or for maintenance and repair of the bridge. In the process of raising the pump pipe layer by layer, each layer of the raised pump pipe is fixedly connected to the embedded bolt 1 through the connecting plate 2. During installation, first fix the connecting plate 2 on the embedded bolt 1 and put the pressing plate 3 in an open state, and then install the newly added steel pipe 4 so that it is docked with the steel pipe 4 of the next layer. Then rotate the pressing plate 3 so that the steel pipe 4 is clamped and then use the connecting structure to fix the pressing plate 3, thereby realizing the installation of the steel pipe 4. After the steel pipe 4 is installed, the gravity of the steel pipe 4 is transmitted to the connecting plate 2 through the load-bearing structure, and then transmitted to the embedded bolt 1, so as to avoid excessive force on the steel pipe 4 of the lower layer and cause danger.

[0029] A rotation groove 5 is provided on the front side of the connecting plate 2, and a rotation pin 7 is fixedly arranged in the rotation groove 5. Connecting arms 8 are fixedly arranged at both ends of the pressing plate 3, and the two connecting arms 8 are both located in the rotation groove 5, and one of the connecting arms 8 is rotatably connected to the rotating pin 7; the connecting structure includes a screw rod 9, and the screw rod 9 passes through the connecting plate 2 and the other connecting arm 8 and is fixedly connected by a first nut 10; when working, after the pressing plate 3 is rotated to clamp the steel pipe 4 between the pressing plate 3 and the connecting plate 2, the screw rod 9 is inserted between the connecting plate 2 and the connecting arm 8 of the pressing plate 3, so that the pressing plate 3 cannot be rotated open, thereby realizing the clamping of the steel pipe 4.

[0030] The connecting plate 2 is sleeved on the outside of the embedded bolt 1, and the embedded bolt 1 is threadedly connected with a second nut 11, and the second nut 11 presses the connecting plate 2 against the outer wall of the super-high pier; during operation, when the connecting plate 2 is inserted into the two embedded bolts 1, the two second nuts 11 are used to fix it.

[0031] The connecting plate 2 is provided with an arc groove 12 which is adapted to the outer wall of the steel pipe 4, and the pressing plate 3 is an arc plate which is adapted to the steel pipe 4; when working, the arc groove 12 and the inner wall of the arc plate are in contact with the outer wall of the steel pipe 4 to limit the steel pipe 4, and the contact surface is large, which has a better effect in preventing the steel pipe 4 from vibrating.

[0032] The two adjacent steel pipes 4 are fixedly connected by threads; during operation, when a new steel pipe 4 is added, the new steel pipe 4 can be butted and installed by screwing.

[0033] The load-bearing structure is a load-bearing ring 13, which is fixedly arranged on the outer wall of the steel pipe 4, and the bottom of the load-bearing ring 13 is in contact with the top of the connecting plate 2; the top of the pressure plate 3 is in the same horizontal plane as the top of the connecting plate 2, and the bottom of the load-bearing ring 13 is in contact with the top of the pressure plate 3; the spacing between the load-bearing rings 13 on two adjacent steel pipes 4 is equal to the spacing between several layers of the embedded bolts 1; during operation, for each newly added section of steel pipe 4, the position of its load-bearing ring 13 just corresponds to the position of the new connecting plate 2. When the new steel pipe 4 is screwed to connect with the steel pipe 4 below, the bottom of the load-bearing ring 13 should be in contact with the connecting plate 2 and the pressure plate 3, so that the gravity of the steel pipe 4 can be transmitted to the embedded bolts 1 through the connecting plate 2, avoiding the risk of the steel pipe 4 breaking due to the pressure on the lower layer of the steel pipe 4.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
