Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and specifically relates to a concrete diverter for bridge high pier construction. Background Technique

[0002] In transportation projects such as highways and railways, the construction quality of bridge piers is an important guarantee for the safety of transportation projects. Among them, when pouring pier concrete, how to safely and quickly pour the concrete into the formwork has an important impact on the safety of the piers. Especially with the increasing demand for building expressways in special terrain such as plateaus, mountains, and river valleys, high piers of extra-large bridges can be seen everywhere. During the construction of high piers of extra-large bridges, how to safely and quickly pour the concrete into the formwork has an even more important impact on the safety of the piers.

[0003] At present, most bridge high pier construction adopts two construction methods. One is to use equipment such as concrete pump trucks and truck-mounted pump machines to convey the concrete from bottom to top through the pumping pipe, and the concrete directly enters the formwork through the pumping pipe, and the pumping pipe is dragged back and forth manually for pouring; the other is to use a concrete pouring funnel. After filling the concrete on the ground, use a truck crane to lift the concrete pouring funnel to the pouring position, and manually open the funnel gate valve for pouring. The above two high pier concrete construction methods have many high-altitude operations, high safety risks, and high site requirements, and it is difficult to meet the requirements of continuous operation and symmetric operation. Moreover, when the concrete directly enters the formwork, the impact force on the pier formwork is relatively large, which will cause quality hazards to the pier construction. At the same time, due to the difficulty in meeting the requirements of continuous operation, the blockage rate of the pumping pipe is greatly increased, the working efficiency of the mechanical equipment is reduced, which in turn leads to material waste, mechanical damage, and large manual consumption and many safety hazards.

[0004] In order to overcome the problems in the background technique, the utility model provides a concrete diverter for bridge high pier construction. By setting a receiving hopper and evenly distributing chutes or troughs circumferentially at the bottom of the receiving hopper, when in use, the concrete is injected into the receiving hopper, and the bridge high pier can be poured evenly and continuously, meeting the symmetry and continuity requirements of concrete pouring, improving work efficiency and the safety of the piers.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "provided with" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] As Figures 1-3 shown, the concrete distributor for bridge high pier construction includes a material receiving hopper 2 and a chute or launder 4 arranged circumferentially along the bottom of the material receiving hopper 2. The cement in the material receiving hopper 2 is introduced into the pier column formwork 1 through the chute or launder 4. Either a chute or a launder can be used in the present utility model, and the chute 4 is preferably used. In this embodiment, the structure protected by the present utility model will be described by taking the use of the chute as an example.

[0024] The chute 4 is connected to the material receiving hopper 2 at an adjustable angle, and the chutes 4 are evenly distributed circumferentially along the bottom of the material receiving hopper 2. The material receiving hopper 2 is arranged at the central position of the pier column formwork 1 and is higher than the pier column formwork 1. The lengths and angles of the chutes 4 are adjustable. The upper port of the chute 4 is communicated with the material receiving hopper 2, and the lower outlet is directly opposite to the pier column formwork 1. The concrete in the material receiving hopper 2 is poured into the pier column formwork 1 through the chute 4.

[0025] The feeding hopper 2 and the chute pipe 4 are connected at an adjustable angle through two socket-type arc-shaped adjusting plates 5 with the same radian. The two socket-type arc-shaped adjusting plates 5 are respectively provided with connection holes 9 with the same spacing. The outer ends of the two socket-type arc-shaped adjusting plates 5 are respectively fixedly connected to the feeding hopper 2 and the chute pipe 4, and the inner ends are opposite to each other and are connected at an adjustable angle by passing high-strength bolts 7 through the connection holes 9.

[0026] The upper port of the chute pipe 4 is provided with a movable arc-shaped plate 8. The movable arc-shaped plate 8 avoids the inlet of the chute pipe and is fixedly connected to the chute pipe 4. The movable arc-shaped plate 8 is arranged inside the feeding hopper 2 and is in contact with the feeding hopper 2. The feeding hopper 2 is provided with an angle adjustment hole for the chute pipe 4 to pass through. The width and length of the angle adjustment hole are both smaller than the movable arc-shaped plate 8. Specifically, no matter what angle is adjusted between the chute pipe 4 and the feeding hopper 2, the movable arc-shaped plate 8 can completely cover the entire angle adjustment hole to prevent the leakage of concrete.

[0027] The inlet end of the chute pipe 4 is provided with a gate valve 6. By controlling the opening and closing of the gate valve 6 and the size of the opening and closing, the flow rate and flow volume of the concrete are controlled.

[0028] As a preferred solution, a frustum-shaped concrete distribution block 3 is provided at the center of the feeding hopper 2. The frustum-shaped concrete distribution block avoids the inlet of the chute pipe 4 to prevent affecting the angle adjustment of the chute 4. By providing the frustum-shaped concrete distribution block 3, the accumulation of concrete at the bottom of the feeding hopper can be avoided.

[0029] The manufacturing / installation process of the present utility model:

[0030] The structure of the present utility model is simple, with strong durability, high flexibility, and convenient and fast operation. Fixing measures can be taken to fixedly connect it to the hydraulic climbing formwork and climb synchronously with the hydraulic climbing formwork, or it can be hoisted and installed by a tower crane after the formwork climbs. The specific installation steps are as follows:

[0031] The feeding hopper 2 is processed with steel plates, and angle adjustment holes are opened at the bottom of the feeding hopper 2 according to the diameter and quantity of the chute pipe 4. The quantity and diameter of the chute pipe 4 need to be determined according to the cross-sectional size of the pier column to meet the concrete pouring volume per unit time. The chute pipe 4 is passed through the angle adjustment hole of the feeding hopper 2 and rigidly welded to the movable arc-shaped plate 8. The movable arc-shaped plate 8 is larger than the angle adjustment hole and is closely attached to the inner wall of the feeding hopper 2 to avoid the leakage of concrete between the feeding hopper 2 and the chute pipe 4 while meeting the angle adjustment of the chute pipe 4. The two socket-type arc-shaped adjusting plates 5 are respectively welded to the bottom of the feeding hopper 2 and the chute pipe 4, and high-strength bolts 7 are passed through the connection holes 9 of the two socket-type arc-shaped adjusting plates 5.

[0032] It is installed on the hydraulic climbing formwork by using a construction tower crane. The chute pipe 4 is extended to the formwork opening. After adjusting the angle of the chute pipe 4, it is fixed with high-strength bolts 7. The chute pipe 4 is made of seamless steel pipe to meet the stiffness, strength, and stability required during the flow process of the concrete.

[0033] The socket type arc-shaped adjusting plate 5 and the high-strength bolts 7 are both made of high-strength materials to have sufficient shear resistance to ensure no deformation and damage during the concrete conveying process.

[0034] Specific usage and operation steps:

[0035] It is installed by hoisting with a tower crane. When entering the concrete pouring stage, use the tower crane to lift the present utility model, adjust the angles of the respective chutes 4 according to the cross-sectional dimensions of the pier column, lap the chute 4 on the formwork opening of the pier column formwork 1, and take measures to temporarily fix the present utility model to the formwork, then the concrete pouring can begin. The concrete is sent into the receiving hopper 2 through a delivery pump, and by controlling the opening and closing and the opening and closing size of the gate valve 6, the concrete can flow to different positions at different flow rates and flow volumes. After the concrete pouring is completed, use the tower crane to lift it and place it on the flat ground, wash the present utility model clean, then pull out the high-strength bolts 7, and fold up the chute 4.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model and not to limit. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present utility model.
