AI Technical Summary
During foundation pit construction, it is difficult to remove sand and mud clumps during the replacement of existing mud during the convection and mixing of new and old mud. The old mud pollutes new mud, and the replacement effect is poor and the speed is slow, and a large amount of new mud is required, resulting in low construction efficiency.
A mud replacement device including a base, telescopic support, grouting tube, swing rod, barrier film, central sliding sleeve and driving motor are designed. By driving the motor, the side arm and upper sliding sleeve are driven to rise to block the The membrane unfolds the original mud and quickly injects new mud to achieve mud replacement.
It improves the efficiency and effect of mud replacement, reduces the use of new mud, avoids old mud contamination of new mud, and significantly improves construction speed and quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a mud replacement device used for construction. Background Art
[0002] In engineering construction, foundation pits are very common facilities. In foundation pit construction, mud quality is very important. If its quality control is not good, it is easy to have problems such as pouring difficulties, hole collapse, and floating of steel cages. In severe cases, it will lead to broken piles, mud jams, and quality and safety accidents. The mud in the drilling process and the mud in concrete pouring have different functions and index parameters. Therefore, mud replacement is a necessary process when pouring underground concrete. Since mud must be used as a wall protection in the foundation pit to prevent hole collapse, the existing mud replacement process is to inject new mud with better indicators into the hole, and use a mud pump to extract the original mud from the hole. That is, the injection of new mud and the extraction of old mud in the foundation pit are carried out at the same time to replace the mud.
[0003] When replacing mud in the traditional way, the new and old muds will produce convection and mixing in the hole, and it is often difficult to replace sand and mud lumps. The old mud will contaminate the new mud, resulting in poor replacement effect. Moreover, a large amount of new mud needs to be injected to replace the old mud, and the speed is slow, which needs to be improved. Utility Model Content

[0018] See also Figure 1 to Figure 2 The utility model provides a technical solution: a mud replacement device for construction, including a base 1, the base 1 is used to be installed around the foundation pit, and the base 1 is fixed to the ground on the side of the foundation pit by a number of fixing nails. A number of telescopic pillars 2 are arranged on the base 1, and the top of the telescopic pillars 2 is connected to a top plate 3. When not in use, under the action of gravity, the top plate 3 will compress the telescopic pillars 2 to the shortest state, and a grouting pipe 4 is arranged in the middle of the top plate 3. A number of swing rods 5 are arranged on the bottom side wall of the grouting pipe 4, and a blocking film 6 is arranged at the bottom of the swing rod 5. The swing rod 5 and the grouting pipe 4 are hingedly connected, and the blocking film 6 is a flexible structure and is fixed on the bottom surface of the swing rod 5.
[0019] A center sleeve 7 is arranged above the swing arm 5, and the center sleeve 7 is movably connected to the grouting pipe 4. A connecting rod 8 is connected between the center sleeve 7 and the swing arm 5. The two ends of the connecting rod 8 are movably connected to the swing arm 5 and the center sleeve 7 respectively. A plurality of vertical poles 9 are connected to the top of the center sleeve 7, and an upper sleeve 10 is connected to the top of the vertical pole 9.
