Description

Technical Field

[0001] The utility model relates to the field of retaining wall buildings, in particular to a buttress type retaining wall structure. Background Art

[0002] A buttress retaining wall refers to a retaining wall with a supporting reinforcement structure on the side, which consists of two parts: the retaining wall and the buttress. Traditional buttress retaining walls are mainly composed of brick walls, while modern buttress retaining walls are mostly built using two methods: prefabrication and cast-in-place. The retaining wall is mainly prefabricated, and the buttress is cast-in-place on the construction site. This type of construction method cannot fully utilize the advantages of short construction period and simple operation of prefabricated construction. It still requires on-site formwork, pouring, drying, and demolding. Therefore, in order to further optimize the construction method of buttress retaining walls, we proposed a buttress retaining wall structure that is fully prefabricated and has steel structure ground piles. Utility Model Content

[0003] The utility model provides a buttress type retaining wall structure, which solves the problem of inconvenient construction of the buttress retaining wall of the existing prefabricated retaining wall plus cast-in-place buttresses.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A buttress-type retaining wall structure, comprising buttresses and a first retaining wall without connecting buttresses and a second retaining wall with connecting buttresses, the first retaining wall and the second retaining wall are connected by straight-row steel structure piles, and two adjacent groups of the first retaining walls arranged perpendicular to each other are connected by angle steel structure piles, and the second retaining wall is fixedly connected to the buttresses;

[0006] A first steel mesh is arranged in the first retaining wall, a second steel mesh is arranged in the second retaining wall, and a third steel mesh is arranged in the buttress. The second steel mesh penetrates the second retaining wall and extends out retaining wall connecting steel bars. The third steel mesh penetrates the buttress and extends out buttress connecting steel bars. The retaining wall connecting steel bars and the buttress connecting steel bars are in contact with each other and inserted into the buttress and the second retaining wall, and are fixed with anchor glue.

[0007] As a preferred technical solution of the utility model, the straight-row steel structure ground piles are composed of two groups of H-shaped steel profiles connected together, and the two sides of the straight-row steel structure ground piles are socketed with the first retaining wall or the second retaining wall, and bolts are penetrated and locked between the first retaining wall or the second retaining wall and the straight-row steel structure ground piles.

[0008] As a preferred technical solution of the utility model, the corner steel structure ground piles are composed of two groups of H-shaped steel profiles arranged perpendicular to each other on both sides, the two groups of steel profiles are connected by right-angle steel and 90-degree arc steel plates, and the outer grooves of the two groups of steel profiles are socketed with the first retaining wall or the second retaining wall, and bolts are penetrated and locked between the first retaining wall or the second retaining wall and the corner steel structure ground piles.

[0009] As a preferred technical solution of the utility model, the bolts are distributed in multiple groups at equal intervals along the height direction of the steel structure piles.

[0010] As a preferred technical solution of the utility model, the cross-section of the connection structure between the buttress and the second retaining wall is arranged in a right-angle trapezoidal shape.

[0011] As a preferred technical solution of the utility model, the bottom ends of the straight steel structure ground piles and the corner steel structure ground piles are buried underground.

[0012] The beneficial effects of the utility model are:

[0013] 1. The difference between the buttress retaining wall and the existing prefabricated retaining wall plus cast-in-place buttress structure is that the buttress retaining wall building structure first implants the ground steel structure piles, then assembles the retaining wall, and finally assembles the buttresses. It uses a fully prefabricated and fully assembled building form, and the construction process is simple and convenient, and it is firm and stable;

[0014] 2. The buttress retaining wall is no longer equipped with buttresses at the corners where the structural strength is significantly higher than that of the straight structure. While meeting the structural strength of the buttress retaining wall, it simplifies the building structure, saves construction costs, and shortens the construction period.

[0015] In summary, the device effectively solves the problem of inconvenience in the construction of the existing prefabricated retaining wall plus cast-in-place buttresses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 A buttress type retaining wall structure comprises buttresses 5 and a first retaining wall 1 without connecting buttresses 5 and a second retaining wall 2 with connecting buttresses 5, wherein the cross section of the connecting structure between the buttresses 5 and the second retaining wall 2 is arranged in a right-angle trapezoidal shape.

[0024] refer to Figure 4 and Figure 5 The straight steel structure ground piles 3 are formed by connecting two groups of H-shaped steel profiles, and the two sides of the straight steel structure ground piles 3 are sleeved with the first retaining wall 1 or the second retaining wall 2, and bolts 6 are penetrated and locked between the first retaining wall 1 or the second retaining wall 2 and the straight steel structure ground piles 3. The corner steel structure ground piles 4 are composed of two groups of H-shaped steel profiles arranged perpendicular to each other on both sides, and the two groups of steel profiles are connected by right-angle angle steels and 90-degree arc steel plates, and the outer grooves of the two groups of steel profiles are sleeved with the first retaining wall 1 or the second retaining wall 2, and bolts 6 are penetrated and locked between the first retaining wall 1 or the second retaining wall 2 and the corner steel structure ground piles 4. There are multiple groups of bolts 6 distributed at equal intervals along the height direction of the steel structure ground piles, and the bottom ends of the straight steel structure ground piles 3 and the corner steel structure ground piles 4 are buried underground.

[0025] The working principle of the device for solving the inconvenience in the construction of the buttress retaining wall of the existing prefabricated retaining wall plus cast-in-place buttress is that the buttress retaining wall is different from the existing prefabricated retaining wall plus cast-in-place buttress structure in that the buttress retaining wall first drives a section of the straight steel structure ground piles 3 and the angle steel structure ground piles 4 into the ground, and then connects the first retaining wall 1 with the angle steel structure ground piles 3 by through bolts 6, and connects the second retaining wall 2 with the straight steel structure ground piles 4 by through bolts 6. The first retaining wall 1 and the second retaining wall 2 are connected by right-angle steel structure ground piles 3. Since the structural strength at the corner is significantly higher than that of the straight structure, the first retaining wall 1 does not need to be equipped with buttresses 5, and is fixed on the side wall of the straight second retaining wall 2 by fixing the exposed steel bars to the embedded steel bars with glue. Connecting buttresses 5; the specific structure is that the first retaining wall 1 and the second retaining wall 2 are connected by a straight row of steel structure piles 3, and the two adjacent groups of first retaining walls 1 arranged perpendicular to each other are connected by corner steel structure piles 4, the second retaining wall 2 is fixedly connected to the buttress 5, a first steel mesh 101 is arranged in the first retaining wall 1, a second steel mesh 201 is arranged in the second retaining wall 2, and a third steel mesh 501 is arranged in the buttress 5, the second steel mesh 201 penetrates the second retaining wall 2 and extends out of the retaining wall connecting steel bars 202, the third steel mesh 501 penetrates the buttress 5 and extends out of the buttress connecting steel bars 502, and the retaining wall connecting steel bars 202 and the buttress connecting steel bars 502 are in contact with each other and inserted into the buttress 5 and the second retaining wall 2, and fixed with anchor glue;

[0026] In summary, the buttress retaining wall building structure adopts a fully prefabricated and fully assembled building form, firstly implanting the ground steel structure piles, then assembling the retaining wall, and finally assembling the buttress 5. The construction process is simple and convenient, and it is firm and stable.
