Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a foundation reinforcement device for construction engineering. Background Art

[0002] The foundation reinforcement device for construction projects is generally a device used to reinforce the foundation during construction projects and is used in various construction projects.

[0003] However, the existing construction engineering foundation reinforcement devices have certain shortcomings when used and need to be improved. First, the contact area between the device and the soil is small, and it is impossible to fully reinforce the foundation, so that the foundation cannot be reinforced more firmly, which reduces the reinforcement effect. Secondly, the device cannot be firmly connected to the soil, which reduces the strength of the device reinforcement connection, so it cannot be used for a long time.

[0004] After searching, a Chinese patent with application number 202122534854.6 discloses a foundation reinforcement device for construction projects, including a reinforcement sleeve rod, a plurality of expansion reinforcement mechanisms are installed on the outside of the reinforcement sleeve rod, a down-pressing rod is installed inside the reinforcement sleeve rod, a rotating connecting rod is installed on the upper end of the down-pressing rod, a locking external thread is installed on the outer bottom of the down-pressing rod, a soil locking mechanism is installed on the lower end of the down-pressing rod, and the expansion reinforcement mechanism includes an expansion groove, a connecting shaft and expansion reinforcement blades, the expansion groove is opened on the inner side of the reinforcement sleeve rod, the connecting shaft is installed inside the expansion groove, and the expansion reinforcement blades are installed on the outside of the connecting shaft. The foundation reinforcement device for construction projects described in the utility model can increase the contact area between the reinforcement sleeve rod and the soil for reinforcement, thereby more firmly reinforcing the foundation, improving the reinforcement effect, and more firmly connecting the device to the soil.

[0005] However, in the above structure, the expansion reinforcement blades are rotatably installed inside the expansion grooves. Although they are pushed out from the expansion grooves under the push of the lower pressure rod, when the reinforcement sleeve is inserted downward into the hole, the lower side of the expansion reinforcement blades is an arc-shaped structure. When it contacts the soil on the side wall of the hole, the expansion reinforcement blades are easily turned out of the expansion grooves and rotated upward on the outside of the reinforcement sleeve. At this time, when the lower pressure rod is inserted into the inside of the reinforcement sleeve, the effect described in the technical solution cannot be achieved. Moreover, this structure is only suitable for holes of suitable sizes that have been pre-drilled, and cannot be used for holes of different sizes. Its use is limited.

[0006] In view of the deficiencies in the above-mentioned structure, the present application proposes a solution to improve the foundation reinforcement device for construction projects. Utility Model Content

[0007] 1. Technical Problems Solved

[0012] As an improvement, the outer wall of the lower end of the sleeve is a conical structure.

[0013] As an improvement, a rotating wheel is sleeved on the outer side of the top of the support shaft.

[0014] As an improvement, the upper side of a side wall of the sliding block located inside the sleeve is located inside the through hole, and the lower side is located outside the through hole.

[0015] As an improvement, the lower end of the rotating rod is a cone head.

[0016] 3. Beneficial Effects

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1 - Attachment Figure 4 As shown, the foundation reinforcement device for construction engineering includes a rotating rod 1 and a sleeve 5, a spiral blade 2 is installed on the outer side of the lower part of the rotating rod 1, a support shaft 4 is installed on the upper end of the rotating rod 1, and the support shaft 4 passes into the sleeve 5, and the outer side of the upper end of the rotating rod 1 and the lower end of the sleeve 5 are respectively provided with matching threads 6, a plurality of groups of through holes 8 are provided on the side wall of the sleeve 5, a slider 9 is slidably provided inside the through hole 8, and the slider 9 is a parallelogram structure, two groups of limit rods 10 are provided between the opposite side walls of the through hole 8, and the slider 9 is provided with two groups of limit slides 11 that cooperate with the limit rods 10 to slide through.

[0025] Through the above structure, the support shaft 4 is rotated, and the rotating rod 1 is driven to rotate through the support shaft 4, and the spiral blade 2 outside the rotating rod 1 is drilled into the soil to fix the casing 5. As the rotating rod 1 moves into the soil, the support shaft 4 passes into the inside of the casing 5, and the rotating rod 1 is connected to the lower end of the casing 5 through the thread 6. The support shaft 4 is supported on the upper side of the lower end of the casing 5. The casing 5 can be driven into the soil through the support shaft 4. After the support shaft 4 passes into the inside of the casing 5, the slider 9 is squeezed to make the slider 9 pass through the through hole 8 and inserted into the soil, so as to reinforce the contact area between the casing and the soil. The specific structure is as follows:

[0026] Combined with Figure 2 and attached Figure 3 As shown, the diameter of the support shaft 4 is larger than the inner wall diameter of the lower end of the sleeve 5 , and the slider 9 is located on one side wall inside the sleeve 5 , with the upper side located inside the through hole 8 , and the lower side located outside the through hole 8 .

[0027] Through the above structure, the support shaft 4 can drive the sleeve 5 to move downward. When the support shaft 4 moves downward inside the sleeve 5, the support shaft 4 presses on the inclined surface of the slider 9 located inside the sleeve 5, and the slider 9 can be squeezed out of the sleeve 5.

[0028] Combined with Figure 2 and attached Figure 3 As shown, the outer wall of the lower end of the sleeve 5 is a conical structure, a rotating wheel 7 is sleeved on the outer side of the top of the support shaft 4, and the lower end of the rotating rod 1 is a cone head 3.

[0029] Through the above structure, the support shaft 4 can be rotated by sleeved the rotating wheel 7 on the top of the support shaft 4. After the reinforcement device is installed, the rotating wheel 7 can be removed and used multiple times. The cone head 3 at the lower end of the rotating rod 1 facilitates drilling the rotating rod 1 into the soil.

[0030] The specific method of use is as follows: the foundation reinforcement device is sent as a whole to the inside of a pre-drilled hole, so that the lower end of the sleeve 5 is supported at the bottom of the hole. When the slider 9 contacts the soil on the side wall of the hole, the inclined structure of the slider 9 will push the slider 9 to move into the through hole 8, and the rotating rod 1 and the spiral blade 2 will drill into the soil at the bottom of the hole. The support shaft 4 passes into the inside of the sleeve 5, and multiple groups of sliders 9 are pushed out of the through hole 8 and inserted into the soil on the side wall of the hole.
