Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering and manufacturing, in particular to a vertical slide pipe structure for preventing concrete segregation. Background Art

[0002] In today's rapid urban construction, many construction projects require concrete pouring. At present, concrete pouring is generally carried out by ground pumps, truck pumps or a combination of the two. Truck pumps have the advantages of flexible construction and fast pouring speed, but they require sufficient construction space and have certain limitations in the pouring range. For some projects with deep foundation pits, large areas, and limited sites, truck pumps cannot be installed. The use of ground pumps is inefficient and cannot be completed in a short time. Large volumes of concrete are transported to the bottom of the foundation pit during pouring in a deep foundation pit with a high drop, and a chute or chute pouring device is required. In the conventional chute method, a full-height scaffolding is generally required for the chute, and a large area of ​​the frame is not attached, which poses a safety hazard and is also costly. The chute method is efficient, occupies a small area, and can meet the needs of on-site concrete pouring. However, the existing chute method generally has an inclined main chute, which is supported by hanging towers at different heights, and then vertical chute pipes are installed on the hanging towers to connect with the main chute, so that concrete at different positions of the main chute can be vertically introduced into the position to be poured. In the existing chute method, the height of the vertical chute often exceeds 2m. During the concrete pouring process, if the height exceeds 2m, segregation will occur when the concrete falls freely. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the utility model provides a vertical chute structure for preventing concrete segregation. The chute structure is installed in the hanging tower area when pouring concrete by the chute method to prevent segregation of concrete due to free fall caused by too large a height difference.

[0004] In order to achieve the above-mentioned technical purpose, the utility model provides a vertical chute structure for preventing concrete segregation, including an inclined main chute and a hanging tower for supporting the inclined main chute, the chute structure including a collecting hopper, multiple vertical pipe sections and multiple inclined chute sections, the collecting hopper is located at the top of the hanging tower and is connected with the inclined main chute, the multiple vertical pipe sections and the multiple inclined chute sections are vertically alternately arranged in the hanging tower, and are interconnected as a whole, the uppermost section and the lowermost section are both vertical pipe sections, the length of each vertical pipe section is not more than 2m, the uppermost vertical pipe section is connected with the discharge port of the collecting hopper, the discharge end of the lowermost vertical pipe section is provided with a discharge elbow, and an inspection port with a baffle is provided near the lower end of each vertical pipe section.

[0005] The preferred technical solution of the utility model is as follows: the angle between each inclined pipe section and the vertical pipe section is 130-140°.

[0006] A better technical solution of the utility model: the vertical chute structure also includes a chute arranged at the bottom of the hanging tower, the chute is erected in an inclined state through a bracket, and its high end is butted against the discharge end of the discharge elbow.

[0007] A more optimal technical solution of the utility model is that the inspection opening adopts a portable baffle structure that can be inserted and removed.

[0008] The preferred technical solution of the utility model is as follows: the uppermost vertical pipe section is welded to the collecting hopper as a whole.

[0009] A better technical solution of the utility model: each vertical pipe section is fixed to the hanging tower by at least one limiting component, and the limiting component includes a limiting ring matching the outer diameter of the vertical pipe section and connecting ribs connecting the limiting ring and the hanging tower, and the vertical pipe section passes through the limiting ring.

[0010] Compared with the existing technology, the utility model has a simple structure, a reasonable design, and is simple and quick to operate. The structure can be installed in the tower suspension area to replace the vertical chute of the existing chute system, thereby slowing down the height difference of the free fall of concrete and effectively preventing concrete segregation; and a maintenance port is reserved in the vertical pipe area to prevent concrete blockage and ensure the quality and efficiency of concrete pouring.
