Description

Technical Field

[0001] The utility model relates to the technical field of casing connection, in particular to a fastening and sealing structure of an alluvial layer casing for grouting construction. Background Art

[0002] Grouting is a common engineering technique and method used primarily for strengthening foundations, filling cracks, and preventing leakage. By injecting a specific slurry into the ground or a structure, soil quality can be effectively improved, bearing capacity increased, and soil erosion prevented, thereby ensuring the stability and safety of the building. During the grouting process, the drill pipe of a drilling rig is used to drive the casing during the drilling of the grouting hole. Grouting can then be performed through the casing into the grouting hole. During construction, due to the limited length of the casing, splicing is necessary. Traditionally, the connection between casings typically uses two-sided connectors connected by fixing bolts to secure the casing. However, because the connectors are larger than the casing itself, they generate significant friction with the soil when entering the grouting hole after connection, which can affect the subsequent extension of the casing into the grouting hole. To address this issue, we propose a fastening and sealing structure for alluvial casing during grouting. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1 、 Figure 2 and Figure 3The utility model provides a technical solution: a fastening and sealing structure for alluvial layer casing of grouting construction, comprising a first connecting member 1 and a second connecting member 2, the inner walls of the first connecting member 1 and the second connecting member 2 are both provided with a threaded groove 3, the first connecting member 1 and the second connecting member 2 are respectively connected and fixed to the end of the casing through the threaded groove 3, a fixing component 4 is assembled between the first connecting member 1 and the second connecting member 2, and the connection and fixation of the first connecting member 1 and the second connecting member 2 are completed by the provided fixing component 4.

[0018] like Figure 1 and Figure 2 As shown in the figure, the side walls of the first connecting member 1 and the second connecting member 2 are respectively integrally formed with an inclined portion 5. The provision of the inclined portion 5 reduces the friction between the first connecting member 1 and the second connecting member 2 and the soil when they are connected and inserted into the grouting hole, making it easier for the drilling rig to drive the casing and the connecting member to be inserted into the soil, and reducing the pause of the casing and the connecting member in the grouting hole.

[0019] like Figure 2 As shown in the figure, the fixing assembly 4 includes a fixing block 41 and a fixing groove 42. The fixing block 41 is integrally formed on the side wall of the second connecting member 2. The fixing groove 42 is opened on the side wall of the first connecting member 1. A fixing hole 43 is opened in the fixing groove 42. A fixing bolt 44 is assembled in the fixing block 41. The fixing bolt 44 is screwed into the fixing hole 43 to realize the connection and fixation of the fixing block 41 and the fixing groove 42, thereby fixing the first connecting member 1 and the second connecting member 2. The number of fixing blocks 41 and fixing grooves 42 is at least four respectively, and the fixing blocks 41 and fixing grooves 42 are evenly distributed on the circumference with the axis of the first connecting member 1 and the second connecting member 2 as the center.

[0020] The fixing bolts 44 are concealed in the side wall of the fixing block 41, which can also reduce the friction generated between the casing and the soil during the insertion of the casing into the grouting hole, making it easier for the casing and the connector to be inserted into the grouting hole.

[0021] like Figure 2 and Figure 3 As shown in the figure, an auxiliary connection component 6 is assembled between the first connection member 1 and the second connection member 2. By setting the auxiliary connection component 6, the connection strength between the first connection member 1 and the second connection member 2 is increased, and the connection between the first connection member 1 and the second connection member 2 is prevented from being bent under force in the grouting hole. If the connection between the first connection member 1 and the second connection member 2 is deformed, it will cause concrete to leak from the connection between the first connection member 1 and the second connection member 2 during the subsequent grouting construction, affecting the sealing effect between the first connection member 1 and the second connection member 2.

[0022] The auxiliary connecting assembly 6 includes an auxiliary connecting shaft 61 and an auxiliary connecting groove 62. The auxiliary connecting shaft 61 is welded to the side wall of the second connecting member 2, and the auxiliary connecting groove 62 is opened on the side wall of the first connecting member 1. There are eight auxiliary connecting shafts 61 and auxiliary connecting grooves 62, and they are evenly distributed around the circumference with the axis of the first connecting member 1 and the second connecting member 2 as the center. After the first connecting member 1 and the second connecting member 2 are connected, the auxiliary connecting shaft 61 is inserted into the auxiliary connecting groove 62 at the corresponding position, which can improve the connection strength between the first connecting member 1 and the second connecting member 2 and avoid deformation after being subjected to force.

[0023] like Figure 2 and Figure 3 As shown in the figure, the outer wall of the auxiliary connecting shaft 61 is sleeved with a rubber layer 63. By providing the rubber layer 63, a certain buffer and protection can be provided between the auxiliary connecting shaft 61 and the auxiliary connecting groove 62, thereby preventing the auxiliary connecting shaft 61 from being subjected to excessive pressure during the grouting process, thereby causing the auxiliary connecting shaft 61 to break, affecting the subsequent strengthening effect of the strength between the first connecting member 1 and the second connecting member 2.

[0024] like Figure 2 and Figure 3 As shown in the figure, a sealing groove 7 is provided on the opposite side walls of the first connecting member 1 and the second connecting member 2, and a sealing ring 8 is installed in the sealing groove 7. By providing the sealing ring 8, the sealing performance of the connection between the first connecting member 1 and the second connecting member 2 after being fixedly connected is further improved, thereby avoiding leakage of the grouting solution during the subsequent grouting operation.

[0025] Working principle: This fastening structure is used to connect and fix the casings during the grouting construction process. The casing is sleeved on the outside of the drill rod of the drilling rig. When the drill bit of the drilling rig completes the drilling of the grouting hole, it drives the casing to be erected in the grouting hole. When the casing needs to be extended and connected, the first connecting member 1 and the second connecting member 2 are screwed to the ends of the casing respectively, and then the fixing block 41 is inserted into the fixing groove 42. The first connecting member 1 and the second connecting member 2 are connected and fixed by the fixing bolt 44. The side walls of the first connecting member 1 and the second connecting member 2 are provided with inclined The inclined portion 5 can effectively reduce the friction between the connection between the first connector 1 and the second connector 2 and the soil when the casing moves along the grouting hole, making it easier to lay the casing along the grouting hole. At the same time, an auxiliary connecting component 6 is also provided between the first connector 1 and the second connector 2, which can effectively increase the connection strength between the first connector 1 and the second connector 2, and avoid the first connector 1 and the second connector 2 from being deformed due to the force in the grouting hole, which affects the sealing effect between the first connector 1 and the second connector 2.
