[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: Figure 1 to Figure 2 As shown, the utility model provides a grouting sleeve for grouting fullness detection, including a horizontally arranged through pipe 2, a plurality of grouting sleeve assemblies 3 are arranged in parallel and at intervals on the through pipe 2, two adjacent grouting sleeve assemblies 3 are connected by a connecting pipe 4, the grouting sleeve assembly 3 includes a lower sleeve 31 vertically connected to the through pipe 2, an end of the lower sleeve 31 away from the through pipe 2 is movably connected to an upper sleeve 32, a slurry outlet hole 33 is arranged on the side wall of the upper sleeve 32, the upper sleeves 32 are connected by a connecting pipe 4 horizontally penetrating the slurry outlet hole 33, and a covering pipe assembly 5 is also connected to the through pipe 2; the ends of both ends of the connecting pipe 4 are also movably provided with matching plugs.

[0023] Before grouting, a corresponding number of upper sleeves 32 can be selected to be connected to each lower sleeve 31 according to the needs of use; during grouting construction, grouting is carried out from one end of the through pipe 2 close to the covering pipe assembly 5, and the slurry enters the through pipe 2 through the covering pipe assembly 5, and then enters each lower sleeve 31 and the upper sleeve 32. Since the slurry outlet holes 33 on each upper sleeve 32 are connected through the connecting pipe 4, when the slurry fills the connecting pipe 4, it can be discharged from both ends of the connecting pipe 4, and then the two ends of the connecting pipe 4 are blocked by a plug, and the through pipe 2 is blocked by the covering pipe assembly 5 (the covering pipe assembly 5 can control the connectivity of the through pipe 2 during grouting or the blocking after the grouting is completed), thereby ensuring the fullness of the slurry, avoiding blocking each lower sleeve 31 one by one, and improving the construction efficiency and speed; that is, it can finally be achieved that at least two grouting sleeve assemblies 3 complete grouting at the same time, thereby improving the grouting efficiency.

[0024] Embodiment 2: Based on Embodiment 1, Figure 1 to Figure 2 As shown, the lower sleeve 31 is provided with an internal thread on the inner circumferential wall away from the end of the through pipe 2, and the upper sleeve 32 is provided with an external thread matched with the internal thread on the outer circumferential wall close to the end of the lower sleeve 31, and the upper sleeve 32 and the lower sleeve 31 are threadedly connected; before grouting, according to the needs of use, a corresponding number of upper sleeves 32 can be selected to be connected to each lower sleeve 31 respectively, that is, the upper sleeve 32 and the lower sleeve 31 are threadedly connected through the internal thread and the external thread; the disadvantages of grouting the grouting sleeve assembly 3 one by one and a large number of grouting times are avoided, and the grouting efficiency is improved at the same time.

[0025] Embodiment 3: Based on Embodiment 1, Figure 1 , Figures 3 to 5 As shown, the covering tube assembly 5 includes a covering tube 51, which is connected to the through tube 2, and a grouting tube 1 is provided at one end of the covering tube 51 away from the through tube 2. The through tube 2 is coaxial with the grouting tube 1, and a circular baffle 52 is horizontally arranged inside the covering tube 51. The circular baffle 52 divides the interior of the covering tube 51 into an upper cavity 53 and a lower cavity 54 which are connected up and down. The upper cavity 53 and the lower cavity 54 are respectively connected to the grouting tube 1 and the through tube 2, and an adjusting threaded rod 55 is movably penetrated at the top of the upper cavity 53. A sealing disk 56 is provided at one end of the adjusting threaded rod 55 located in the upper cavity 53, and the sealing disk 56 is in conflict with the circular baffle 52.

[0026] Before grouting construction, the adjusting threaded rod 55 can be rotated to drive the sealing disk 56 to move away from the annular partition 52. At this time, the upper cavity 53 and the lower cavity 54 are connected through the annular partition 52, and grouting is carried out from the end of the through pipe 2 close to the sealing tube assembly 5. The slurry enters the through pipe 2 through the sealing tube assembly 5 and then enters each grouting sleeve assembly 3; when the grouting construction is completed, the adjusting threaded rod 55 can be rotated to drive the sealing disk 56 to move toward the annular partition 52. At this time, the upper cavity 53 and the lower cavity 54 are not connected. At this time, the leakage of slurry in each grouting sleeve assembly 3 can be avoided, thereby ensuring the fullness of the grouting material.

[0027] The outer diameter of the sealing disk 56 is larger than the inner diameter of the annular partition 52 , so that when the sealing disk 56 and the annular partition 52 collide with each other, the inner diameter of the annular partition 52 can be blocked, thereby achieving disconnection between the upper cavity 53 and the lower cavity 54 .

[0028] The adjusting threaded rod 55 , the annular partition plate 52 and the sealing disk 56 are coaxial, which is conducive to driving the sealing disk 56 to move smoothly when the adjusting threaded rod 55 is rotated, and can accurately interfere with the annular partition plate 52 to achieve disconnection between the upper cavity 53 and the lower cavity 54 .

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
