[0002] During the road construction phase, temporary retaining walls are set up near the excavated pits or slopes as temporary support structures. These temporary retaining walls prevent soil collapse during construction, protect the construction section from external vehicles, and safeguard the safety of construction personnel and equipment. At the construction site, the temporary retaining walls are generally supported by steel pipes as diagonal bracing structures, with the top and bottom ends of the steel pipes fixed to the retaining wall and the ground respectively by bolts.

[0003] In the above-mentioned single steel pipe bracing structure, the contact area between the top and bottom of the steel pipe bracing and the wall and the ground is small, and the foundation bearing capacity is insufficient. In the scenario of frequent driving of large vehicles on the construction site, vibration may occur, and the steel pipe bracing may be displaced. The stability of the single steel pipe bracing wall is insufficient and needs to be improved.

[0004] Existing single steel pipe diagonal bracing supports for road construction retaining walls have the problem of not increasing the contact area between the diagonal bracing and the wall and ground. Therefore, this application proposes a road construction support structure. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 7 This utility model provides a technical solution: a road construction support structure, including a support base 1, and a fixed beam 11 and a support beam 12 welded together. Figure 1F in the diagram represents a temporary retaining wall structure built at a road construction site. When supporting retaining wall F, under manual operation by construction personnel, fixed beam 11 and support beam 12 are bolted to the ground. The contact area between fixed beam 11 and support beam 12 and the ground is a frame-type contact, resulting in a large contact area, increasing the foundation bearing capacity, and preventing displacement of fixed beam 11 and support beam 12, which could lead to displacement of the diagonal brace 3. The diagonal brace 3 includes a rotating cylinder 31 welded to one end and a limiting component fixedly connected to the other end. The bottom end of the diagonal brace 3 is connected to the support base 1, and the top end of the diagonal brace 3 supports the support wall panel 42, achieving the purpose of diagonally supporting retaining wall F. The limiting component includes a welded mounting seat 2 and a plug 24, a fixing block 21 perpendicular to the surface of the mounting seat 2, a fixing shaft 22 welded between opposing fixing blocks 21, and an adjusting rotating cylinder 23 rotatably sleeved on the outside of the fixing shaft 22. When installing the diagonal brace 3, the mounting seat 2 is installed on the support beam 12, and the plug... Block 24 is embedded inside the support beam 12 to limit the bottom of the mounting base 2 and the diagonal brace 3. The position of the mounting base 2 on the support beam 12 can be manually changed, thereby changing the diagonal brace inclination angle of the diagonal brace 3, which facilitates changing the support position on the retaining wall F. The support components fixedly connected to the wall include a crossbar 5 with one end bolted to the mounting base 2, a reinforcing plate 6 with the other end bolted to the crossbar 5, a fixed circular plate 41 and a support wall plate 42 welded together, and a through fixed circular plate. The bolt rod 43 of 41 and the reinforcing strip 7, which is fixed to the supporting wall plate 42 and the reinforcing plate 6 by bolts at both ends, are fixed to the retaining wall F. When fixed to the retaining wall F, the supporting wall plate 42 is fixedly connected to the retaining wall F, the top end of the reinforcing strip 7 is fixedly connected to the supporting wall plate 42, the two ends of the crossbar 5 are fixedly connected to the reinforcing plate 6 and the mounting base 2, the supporting wall plate 42 and the reinforcing strip 7 are fixedly connected to the supporting wall plate 42, and the reinforcing strip 7, the crossbar 5 and the diagonal brace 3 form a triangular diagonal brace support structure to increase the stability of the diagonal brace 3.

[0029] In this embodiment, the support beam 12 has fixed beams 11 that are vertically and symmetrically distributed. The surface of the support beam 12 is provided with a recessed groove a that cooperates with the insert block 24. The insert block 24 is embedded in the groove a of the support beam 12 to limit the bottom of the mounting seat 2 and the diagonal brace 3. The mounting seat 2 and the support beam 12 are separate structures, and the position of the mounting seat 2 on the support beam 12 can be changed.

[0030] In this embodiment, both the fixed circular plate 41 and the rotating cylinder 31 are provided with circular holes for the bolt rod 43 to pass through. The bolt rod 43 is screwed to a nut at one end through the fixed circular plate 41 and the rotating cylinder 31. Construction personnel can manually adjust the angle and position of the fixed circular plate 41 so that the supporting wall plate 42 fits closely with the retaining wall F. Then, the bolt rod 43 and the nut are used to lock and fix the wall, so that the top of the diagonal brace 3 supports the retaining wall F.

[0031] In this embodiment, the end of the crossbar 5 furthest from the mounting base 2 is a right-angle structure, which facilitates the fixed connection between the crossbar 5 and the reinforcing plate 6. The two ends of the reinforcing strip 7 are respectively inserted into the interior of the opposing surfaces of the reinforcing plate 6 and the supporting wall plate 42. The reinforcing strip 7 is connected to the supporting wall plate 42 and the reinforcing plate 6 to form an integral structure, increasing the contact area with the retaining wall F. The supporting wall plate 42 and the reinforcing plate 6 have the same thickness. The surfaces of the reinforcing plate 6, the supporting wall plate 42 and the reinforcing strip 7 on the same side are flush. The reinforcing strip 7, the reinforcing plate 6 and the supporting wall plate 42 are in close contact with the retaining wall F. The crossbar 5, the reinforcing strip 7 and the diagonal brace 3 form a right-angled triangular diagonal brace support structure, which increases the stability of the diagonal brace structure compared with the traditional single diagonal brace support.

[0032] In this embodiment, the crossbars 5 installed between the mounting base 2 and the reinforcing plate 6 are denoted as C1 and C2, and the reinforcing strips 7 installed between the reinforcing plate 6 and the supporting wall panel 42 are denoted as D1 and D2. C1 corresponds one-to-one with the opposite D1 on the same side. The lengths of the crossbars 5 of C1 and C2 are different, and the lengths of the reinforcing strips 7 of D1 and D2 are different. The appropriate lengths of the reinforcing strips 7 and crossbars 5 can be selected according to the actual situation.

[0033] Working principle and usage process of this utility model:

[0034] When supporting the retaining wall F, the fixed beam 11 and the supporting beam 12 are fixed to the ground by bolts. The contact area between the fixed beam 11 and the supporting beam 12 and the ground is a frame-type contact, which has a large contact area, increases the bearing capacity of the foundation, and avoids the displacement of the fixed beam 11 and the supporting beam 12, which would cause the diagonal bracing rod 3 of the diagonal brace to be displaced.

[0035] The mounting base 2 at the bottom of the diagonal brace 3 is installed, and the insert 24 is embedded in the groove a of the support beam 12 to limit the mounting base 2 and the bottom of the diagonal brace 3. The mounting base 2 and the support beam 12 are separate structures, and the position of the mounting base 2 on the support beam 12 can be changed.

[0036] The reinforcing strip 7 is connected to the supporting wall panel 42 and the reinforcing plate 6 to form an integral structure, and the integral structure is fixedly connected to the retaining wall F.

[0037] Meanwhile, the fixed circular plate 41 is fixedly connected to the rotating cylinder 31 by bolt rod 43 and nut, and the crossbar 5 is fixedly connected to the mounting base 2;

[0038] The reinforcing strip 7, the reinforcing plate 6, and the supporting wall panel 42 are attached to the retaining wall F. The horizontal bar 5, the reinforcing strip 7, and the diagonal brace 3 form a right-angled triangular diagonal bracing support structure, which increases the stability of the diagonal bracing structure compared to the traditional single diagonal bracing support.

[0039] In summary, this application provides a support design that increases the contact area between the diagonal brace 3 and the wall and ground. The fixed beam 11 and the support beam 12 have a large contact area with the ground, which increases the bearing capacity of the foundation and avoids displacement of the fixed beam 11 and the support beam 12. The crossbar 5, the reinforcing strip 7, and the diagonal brace 3 form a right-angled triangular diagonal bracing support structure, which increases the stability of the diagonal bracing structure compared with the traditional single diagonal bracing support.

[0040] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
