[0003] However, currently, when driving steel piles, after measuring the inclination angle of the first section with a protractor, subsequent construction is often judged based on the construction workers' experience to determine whether the inclination angle meets the requirements. This results in an inability to effectively and consistently control the inclination angle of the steel piles, increasing the possibility of construction errors and affecting project quality and safety. Furthermore, in complex geological conditions or special engineering environments, it can be difficult to accurately judge the inclination angle of the steel piles based solely on experience.

Under the premise of ensuring that the angle between the support member and the connecting member does not change, the inclination angle of the steel pipe pile can be continuously adjusted and controlled by observing the tightness of the fit between the buffer and the steel pipe and the change in its thickness, so that the inclination angle of the steel pipe pile meets the design requirements, which can more effectively support the side wall of the pit foundation, thereby improving the stability of the foundation pit retaining structure and preventing lateral movement and collapse of the soil. In addition, the fixing member is set within the installation surface, and the extension direction of the fixing member is parallel to the installation surface, which increases the contact area between the bracket device and the installation surface, thereby facilitating the overall stability of the bracket device, so that the support member can better fit the steel pipe pile, and facilitates the steel pipe pile to tilt along the preset angle during piling.

[0045] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0046] like Figures 1 to 4As shown, this embodiment provides a bracket device 100, which is used to control the inclination angle of the steel pipe pile 1000 for front-support grouting. The bracket device 100 includes a fixing member 1, a connecting member 2, a buffer member 4 and a support member 3. The fixing member 1 is arranged in the installation surface, and the extension direction of the fixing member 1 is parallel to the installation surface. The two ends of the connecting member 2 are respectively connected to the fixing member 1 and the support member 3. The connecting member 2 extends in the vertical direction, one side of the buffer member 4 is connected to the support member 3, and the other side of the buffer member 4 abuts against the steel pipe pile 1000; the angle between the support member 3 and the connecting member 2 is complementary to the preset angle between the steel pipe pile 1000 and the installation surface. With the above-mentioned structural form, by fitting the buffer member 4 to the steel pipe pile 1000, under the premise of ensuring that the angle between the support member 3 and the connector 2 does not change, the inclination angle of the steel pipe pile 1000 can be continuously adjusted and controlled by observing the tightness of the fit between the buffer member 4 and the steel pipe pile 1000 and the change in its thickness, so that the inclination angle of the steel pipe pile 1000 meets the design requirements, thereby allowing the steel pipe pile 1000 to more effectively support the side wall of the pit foundation, thereby improving the stability of the foundation pit retaining structure and preventing lateral movement and collapse of the soil. In addition, the fixing member 1 is set within the installation surface, and the extension direction of the fixing member 1 is parallel to the installation surface 2000, which increases the contact area between the bracket device 100 and the installation surface 2000, thereby facilitating the overall stability of the bracket device 100, so that the buffer member 4 can better fit the steel pipe pile 1000, and is conducive to observing and controlling the inclination of the steel pipe pile 1000 along the preset angle during pile driving.

[0047] It should be noted that the aforementioned complementary angle between support member 3 and connector 2 and the preset angle between steel pipe pile 1000 and the mounting surface refers to the fact that connector 2 is positioned away from the connection between steel pipe pile 1000 and the mounting surface, and support member 3 extends from connector 2 toward the connection between steel pipe pile 1000 and the mounting surface. Furthermore, the preset angle is set based on the preset inclination angle of steel pipe pile 1000 and is not limited to a specific value.

[0048] In actual use, the fixing member 1, the connecting member 2, and the supporting member 3 are all steel bars. The steel bars should not be too thick or too thin. Depending on the actual situation, φ10-14 mm threaded steel bars can be selected. In addition, the end of the fixing member 1 away from the connecting member 2 can be determined according to the conditions of the mounting surface 2000. If the mounting surface 2000 is soil, a hook 15 can be provided at the end for anchoring, further improving the stability of the fixing member 1.

[0049] like Figure 3 As shown, the bracket device 100 also includes a limit member 5, which is arranged on the side of the support member 3 away from the buffer member 4. In the projection perpendicular to the extension direction of the support member 3, at least one end of the limit member 5 extends beyond the support member 3 and is used to abut against the buffer member 4, thereby preventing the buffer member 4 from rotating around the support member 3.

[0050] In actual use, there are multiple limiters 5, and the multiple limiters 5 are spaced apart along the extension direction of the buffer member 4, thereby improving the limiting strength of the limiters 5. In addition, to further improve the limiting strength of the limiters 5, it is preferred that both ends of the limiters 5 extend beyond the support member 3 in the projection perpendicular to the extension direction of the support member 3.

[0051] In this embodiment, the buffer member 4 is a sponge, and the thickness of the sponge is 5 cm, so that the construction inclination angle can be continuously controlled and adjusted during construction according to the fit between the sponge and the steel pipe pile 1000 and the change in the thickness of the sponge. It should be specifically noted that in this embodiment, the thickness of the sponge is required not to change too much. In other embodiments, the type and thickness of the buffer member 4 can be adjusted according to actual needs and are not limited here. In addition, in this embodiment, the limiter 5 is a short steel bar. In other embodiments, the type of the limiter 5 can be adjusted according to actual needs and are not limited here.

[0052] The bracket device 100 also includes a fastener, which is spirally wound around the buffer 4 and the limiter 5 along the extension direction of the buffer 4 to connect the buffer 4 and the limiter 5, ensuring that the thickness of the buffer does not change or deform when fixing the buffer.

[0053] The above structural form can provide a stronger connection force and ensure the stability and reliability of the connection.

[0054] In this embodiment, the fastener is a wire. In other embodiments, the fastener may be of other types and is not limited here. In addition, in this embodiment, when the fixing member secures the buffer 4, it is necessary to ensure that the buffer 4 does not deform and that the thickness of the buffer 4 does not change. This facilitates observation of the thickness change during construction to determine whether the inclination angle of the steel pipe pile is within the design range.

[0055] like Figure 1 As shown, the fixing member 1 includes a first fixing portion 11 and a second fixing portion 12, both of which are connected to the connecting member 2, and the first fixing portion 11 and the second fixing portion 12 extend in different directions. This structural form increases the contact area between the bracket device 100 and the mounting surface 2000, improving the overall stability of the bracket device 100, allowing the support member 3 to better fit the steel pipe pile 1000, and facilitating the tilting of the steel pipe pile 1000 at a predetermined angle during driving.

[0056] like Figure 1As shown, the fixing member 1 further includes a third fixing portion 13, which is connected to the first fixing portion 11 and the second fixing portion 12. With the above structure, the third fixing portion 13 improves the structural strength and stability of the first fixing portion 11 and the second fixing portion 12, thereby facilitating the improvement of the structural strength and stability of the fixing member 1.

[0057] like Figure 1 As shown, the fixing member 1 further includes a fourth fixing portion 14, one end of which is connected to the first fixing portion 11 and the second fixing portion 12, and the other end of the fourth fixing portion 14 is connected to the third fixing portion 13. With this structure, the fourth fixing portion 14 further improves the structural strength and stability of the first fixing portion 11 and the second fixing portion 12, thereby further improving the structural strength and stability of the fixing member 1.

[0058] Specifically, an oblique steel bar is welded between the connecting member 2 and the supporting member 3 and between the connecting member 2 and the fourth fixing portion 14 to connect them, thereby improving the overall structural strength of the bracket device 100.

[0059] The connector 2 and support member 3 are integrally formed. Specifically, the support member 3, connector 2, and fourth fixing portion 14 can be formed by bending steel bars, and the connector 2 can be connected to the first fixing portion 11 and the second fixing portion 12 by welding. In other embodiments, other connection methods are also possible and are not limited here.

[0060] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
