Description

Technical Field

[0001] The present invention relates to the technical field of concrete pouring auxiliary devices, and in particular to a device for preventing turbulent flow during the pouring of diaphragm walls, and also relates to a method for using a device for preventing turbulent flow during the pouring of diaphragm walls. Background Art

[0002] The diaphragm wall is a commonly used construction technique in foundation engineering, mainly used for the excavation support of deep foundation pits, the basement exterior walls of buildings, anti-seepage walls, etc. The diaphragm wall uses a grooving machine to excavate a long and narrow deep groove along the peripheral axis of the deep excavation project under the condition of slurry wall protection. After cleaning the groove, a steel reinforcement cage is hoisted into the groove, and then underwater concrete is poured by the conduit method to form a unit groove section. In this way, it is carried out section by section to build a continuous reinforced concrete wall underground. The diaphragm wall can effectively reduce the amount of earthwork excavation, thereby reducing the project cost. At the same time, the vibration and noise generated during the construction process are small, which is suitable for construction in urban dense building groups. And the wall has large stiffness, good integrity, anti-seepage and durability, reliable quality. At the same time, it can make full use of the limited ground and space within the building red line to give play to the investment benefit, and is applicable to various foundation conditions such as soft alluvial strata, medium-hard strata, and dense gravel strata. Therefore, it plays an increasingly important role in modern engineering construction. However, when pouring concrete for the diaphragm wall, turbulent flow will occur, which will affect the pouring effect. Therefore, it is necessary to use an anti-turbulent flow device to reduce the generation of turbulent flow.

[0003] For example, the patent with the publication number CN222161215U discloses a device for preventing turbulent flow during the pouring of diaphragm walls, including an H-shaped steel body and a steel bar group. The H-shaped steel body includes a web and a flange. The cross-sectional dimensions of the opposite surface of the H-shaped steel body and the embedded H-shaped steel are the same; multiple groups of the steel bar groups are located on one side of the H-shaped steel body close to the embedded H-shaped steel and extend out of the H-shaped steel body. The steel bar group includes two steel bars with the same size specifications. The two steel bars of each group of steel bar groups are symmetrically fixed on the inner and outer sides of the web or the flange respectively. One end of the steel bar extending out of the H-shaped steel body is provided with an elbow. This technical solution is convenient for docking and fixing with the embedded H-shaped steel, effectively preventing turbulent flow during the pouring of the diaphragm wall; at the same time, it has a simple structure, is easy to manufacture, and can be reused.

[0004] However, the above technical solution reduces the generation of turbulent flow by adjusting the structure of the steel reinforcement cage. Although this method can reduce the generation of turbulent flow, the uniformity of the concrete during concrete pouring is also a cause of turbulent flow generation. At the same time, impurities adhering to the side wall of the deep groove during pouring will also generate turbulent flow. The above technical solution cannot reduce the turbulent flow caused by the above two reasons. Summary of the Invention

[0005] Based on the deficiencies of the above-mentioned existing technologies, the technical problem to be solved by the present invention is to provide a device for preventing turbulent flow during the casting of diaphragm walls, which has the advantages of being able to evenly distribute concrete and improve the smoothness of the side walls of deep trenches, thereby reducing the generation of turbulent flow.

[0006] To achieve the above object, the present invention adopts the following technical measures:

The extension rod is threadedly sleeved on the extension threaded rod, and a cleaning brush is fixedly installed at one end of the extension rod.

[0014] Thus, the side wall of the deep groove can be cleaned by the cleaning component with a specific structure.

[0015] Furthermore, lock catches are fixedly installed on four sides of the bucket cover. The bucket cover is connected to the mixing bucket through the lock catches. A feed pipe is fixedly installed on one side of the bucket cover, and a sealing cover is arranged at the upper end of the feed pipe.
