Description
Technical Field
[0001] The utility model relates to the field of foundation reinforcement, in particular to a foundation reinforcement device. Background Art
[0002] Grouting reinforcement is mostly used for foundation reinforcement. A hole matching the grouting pipe is opened in the foundation that needs to be reinforced, and the grouting pipe is inserted. The prepared chemical slurry or cement slurry is injected into the holes in the ground through the grouting pipe, so that the slurry combines with the soil, thereby achieving the effect of reinforcing the foundation.
[0003] Since the grouting pipe needs to be inserted into the installation hole opened on the foundation backfill soil, the grouting holes on the grouting pipe are easy to scrape off the soil on the inner wall of the hole when the grouting pipe moves in the installation hole, causing part of the grouting holes to be blocked by the soil, affecting the subsequent grouting uniformity. Utility Model Content
[0004] The purpose of the utility model is to solve the following problems existing in the prior art: since the grouting pipe needs to be inserted into the installation hole opened on the foundation backfill soil, and the grouting holes on the grouting pipe are easy to scrape off the soil on the inner wall of the opening hole when the grouting pipe moves in the installation hole, causing part of the grouting holes to be blocked by the soil, affecting the uniformity of subsequent grouting.
[0005] In order to solve the problems existing in the prior art, the utility model provides a foundation reinforcement device, including a grouting pipe, wherein an upper cover is provided at the top of the grouting pipe, a plug-in tube plugged into the inner side of the grouting pipe is provided in the middle of the bottom end of the upper cover, a plurality of fixing pins in contact with the grouting pipe are plugged at the edge of the upper cover, and a connecting pipe is plugged in the middle of the upper cover.
[0006] Preferably, the outer side of the grouting pipe is provided with a plurality of rows of through holes arranged at equal angles around the center of the grouting pipe.
[0007] Preferably, the upper and lower parts of the plug-in tube are provided with a plurality of rows of discharge holes arranged at equal angles around the center of the plug-in tube, and the discharge holes in the upper and lower parts of the plug-in tube are staggered.
[0008] Preferably, the angle between the discharge holes at the upper and lower parts of the plug-in tube is smaller than the angle between the through holes of the grouting pipe.
[0009] Preferably, a hexagonal block is provided on the top of the upper cover.
[0010] Preferably, a sleeve is vertically expanded downward on the edge of the upper cover, and the fixing pin is inserted into the top end of the sleeve of the upper cover and contacts the grouting pipe.
[0011] Preferably, the outer side of the plug-in tube is in close contact with the inner side of the grouting pipe.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The utility model twists the upper cover to make the plug-in tube rotate inside the grouting pipe, so that the plug-in tube blocks the through hole of the grouting pipe to prevent backfill soil from entering the grouting pipe. At the same time, the upper cover is rotated to connect the discharge holes at the upper and lower parts of the plug-in tube to the lower and upper through holes of the grouting pipe respectively, so that the grouting of the grouting pipe is segmented, which prevents the slurry from surging upwards during the overall grouting, resulting in the need for multiple grouting to complete the reinforcement of the backfill foundation.

[0018] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0019] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0020] Example 1
[0021] like Figure 1-3 As shown, a foundation reinforcement device includes a grouting pipe 1, a top cover 3 is provided at the top of the grouting pipe 1, a plug-in tube 2 plugged into the inner side of the grouting pipe 1 is provided at the middle of the bottom end of the upper cover 3, a plurality of fixing pins 4 in contact with the grouting pipe 1 are plugged at the edge of the upper cover 3, and a connecting pipe 5 is plugged in the middle of the upper cover 3.
[0022] The outer side of the grouting pipe 1 is provided with multiple rows of through holes arranged at equal angles around the center of the grouting pipe 1, and the upper and lower parts of the plug-in pipe 2 are provided with multiple rows of discharge holes arranged at equal angles around the center of the plug-in pipe 2, and the discharge holes in the upper and lower parts of the plug-in pipe 2 are staggered, wherein the number of the multiple rows of through holes in the grouting pipe 1 and the number and height positions of the multiple rows of discharge holes in the plug-in pipe 2 are the same.
[0023] The angle between the discharge holes at the upper and lower parts of the plug-in tube 2 is smaller than the angle between the through holes of the grouting tube 1. The discharge hole of the plug-in tube 2 can be located between the two through holes of the grouting tube 1, so that the through hole of the grouting tube 1 is blocked when not in use.
[0024] A hexagonal block is provided at the top of the upper cover 3, and a sleeve is vertically expanded downward at the edge of the upper cover 3. The fixing pin 4 is inserted into the top of the sleeve of the upper cover 3 and contacts the grouting pipe 1. The hexagonal block makes it easier to rotate the plug-in pipe 2. At the same time, the fixing pin 4 is inserted into the inner side of the sleeve of the upper cover 3 and contacts the grouting pipe 1, but the plug-in pipe 2 is fixed on the grouting pipe 1 to prevent the plug-in pipe 2 from being separated from the grouting pipe 1 when the pressure device is grouting.
[0025] The outer side of the plug-in tube 2 is in close contact with the inner side of the grouting tube 1 to prevent the slurry from surging upward.
[0026] Working principle:
[0027] When in use, the upper cover 3 is twisted to rotate the plug-in tube 2 inside the grouting tube 1, so that the plug-in tube 2 blocks the through hole of the grouting tube 1 to prevent backfill soil from entering the grouting tube 1. At the same time, the upper cover 3 is rotated to make the discharge hole at the lower part of the plug-in tube 2 coaxial with the through hole of the grouting tube 1, so that the grouting work is carried out on the bottom of the grouting tube 1 first, and the upper cover 3 is continued to be rotated to connect the upper discharge hole of the plug-in tube 2 with the upper through hole of the grouting tube 1, and at the same time, the lower discharge hole of the grouting tube 1 is blocked, so that the grouting of the grouting tube 1 is segmented, which prevents the slurry from surging upward during the overall grouting, resulting in multiple groutings required to complete the reinforcement of the backfill foundation.
[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
