[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0031] The first aspect of the present invention provides a novel trail retaining wall. Figure 2 As shown, it includes a retaining wall body 1, a support body 2 and a guardrail 3;

[0032] The retaining wall body 1 comprises a first retaining wall body 11 and a second retaining wall body 12. At least one of the upper and lower ends of the first retaining wall body 11 is connected to the second retaining wall body 12. The hardness of the first retaining wall body 11 is greater than that of the second retaining wall body 12.

[0033] The support body 2 is connected to one side of the first retaining wall body 11 , the top surface of the support body 2 is used for people to walk on, and the end of the support body 2 away from the first retaining wall body 11 is connected to the guardrail 3 .

[0034] like Figure 1 As shown, the existing retaining wall is made of flaked concrete as a whole. The left side of the retaining wall blocks the river channel, and the right side is a residential area. The retaining wall cannot allow residents to pass along its extension direction. Due to the difficulty in relocating the river channel, the existing retaining wall has gradually become an obstacle to residents' daily travel.

[0035] The new type of walking trail retaining wall provided in the above embodiment includes, on the one hand, a support body 2 and a guardrail 3. The support body 2 can provide walking space for people, and the guardrail 3 can ensure people's walking safety, solving the problem of daily travel difficulties for residents caused by the difficulty of river channel relocation.

[0036] Secondly, the retaining wall body 1 includes a first retaining wall body 11 and a second retaining wall body 12 with different hardness. The support body 2 is connected to the first retaining wall body 11 with greater hardness. Compared with the second retaining wall body 12, the first retaining wall body 11 can support the support body 2 more stably to ensure the stability of the trail retaining wall.

[0037] In some embodiments, Figure 2 As shown, the first retaining wall body 11 has a first side surface 111 close to the river and a second side surface 112 facing away from the river and facing the residential area, and the support body 2 is connected to the first side surface 111 .

[0038] The above arrangement can make full use of the space above the river, and the walking trail retaining wall will not occupy the space on the side of the first retaining wall body 11 facing the residential area, and the layout is more reasonable.

[0039] The structure of the support 2 is described in detail below:

[0040] In some embodiments, Figure 3As shown, the support body 2 includes supporting steel bars and a cast body 21. The supporting steel bars include a connecting portion 22 and a cantilever portion 23 connected to the connecting portion 22. The connecting portion 22 is embedded in the first retaining wall body 11. The cantilever portion 23 is located outside the first retaining wall body 11 and embedded in the cast body 21.

[0041] During construction, the connection part 22 is prefabricated in the steel frame of the first retaining wall 11, and is embedded in the first retaining wall 11 as the first retaining wall 11 is cast and formed, and then the cast body 21 can be cast and formed. Of course, the cast body 21 can also be cast and formed integrally with the first retaining wall 11.

[0042] The connecting portion 22 and the cantilever portion 23 both include a first steel bar 221 arranged along the retaining wall body 1 and a second steel bar 222 perpendicular to the first steel bar 221 , and the first steel bar 221 and the second steel bar 222 are fixedly connected.

[0043] by Figure 3 For example, the extension direction of the first steel bar 221 is parallel to the direction of the retaining wall body 1, that is, parallel to the extension direction of the retaining wall body 1, and the second steel bar 222 is perpendicular to the first steel bar 221. Each second steel bar 222 can be parallel to the horizontal plane or have an angle with the horizontal plane. The first steel bar 221 and the second steel bar 222 can be welded, and the two form the skeleton structure of the support body 2 to ensure the support stability of the support body 2.

[0044] In some embodiments, Figure 3 As shown, the support body 2 includes a top surface and a bottom surface. The top surface is horizontally arranged for people to walk on, and the bottom surface gradually decreases in height from the guardrail 3 to the direction of the first retaining wall body 11.

[0045] The force on one end of the support body 2 connected to the first retaining wall body 11 is relatively concentrated. The above arrangement can increase the connection area between the support body 2 and the first retaining wall body 11, thereby ensuring the connection firmness of the support body 2, effectively ensuring the long-term and effective use of the trail retaining wall, and extending the maintenance cycle.

[0046] On the basis of the above embodiment, both the connecting portion 22 and the cantilever portion 23 are provided with a horizontal second steel bar parallel to the top surface of the support body 2, and the above-mentioned horizontal second steel bar is arranged close to the top end of the support body 2; both the connecting portion 22 and the cantilever portion 23 are provided with an inclined second steel bar parallel to the bottom surface of the support body 2, and the inclined second steel bar is arranged close to the bottom end of the support body 2, and the angle between the horizontal second steel bar and the inclined second steel bar can be 10-30°.

[0047] Specifically, the angle between the horizontal second steel bar and the inclined second steel bar may be 10°, 15°, 20° or 30°.

[0048] In some embodiments, a steel bar arranged parallel to the first side surface 111 may be fixedly connected to the connection portion 22 . The steel bar may increase the downward pressure that the support body 2 can withstand, thereby improving the support capacity of the support body 2 .

[0049] The width of the support body 2 protruding from the first retaining wall body 11 in the horizontal direction may be 2m, providing sufficient space for people to walk.

[0050] In addition, the support body 2 may extend into the first retaining wall body 11 to a depth of 0.9 m in the horizontal direction.

[0051] In some embodiments, Figure 2 As shown, a cement mortar layer 4 and a sidewalk brick layer 5 are provided on the top surface of the support body 2 , and the cement mortar layer 4 is sandwiched between the support body 2 and the sidewalk brick layer 5 .

[0052] The cement mortar layer 4 and the sidewalk brick layer 5 can protect the support body 2 .

[0053] The structure of the guardrail 3 is described in detail below:

[0054] In some embodiments, Figure 4 and Figure 5 As shown, the guardrail 3 includes a plurality of columns 31 and a plurality of baffles 32 . The plurality of columns 31 are spaced apart along the extension direction of the support body 2 , and a baffle 32 is connected between two adjacent columns 31 .

[0055] The upright column 31 serves to connect and support the baffle plate 32 , and the baffle plate 32 can protect people from the side and ensure the safety of people walking.

[0056] Specifically, Figure 5 As shown, a limiting groove 311 is provided on the side of the column 31 facing the baffle 32. When installing, the end of the column 31 can be inserted into the limiting groove 311. The thickness of the limiting groove 311 can be substantially equal to the thickness of the baffle 32, thereby limiting the baffle 32 along a plane perpendicular to the baffle 32. The distance between the bottoms of the limiting grooves 311 oppositely arranged on two adjacent columns 31 can be substantially equal to the length of the baffle 32, thereby limiting the baffle 32 along the length direction of the baffle 32.

[0057] Specifically, the end of the baffle 32 extending into the limiting groove 311 is chamfered to make the end thickness of the baffle 32 smaller, so that the baffle 32 can be easily inserted into the limiting groove 311. The cross-sectional shape of the limiting groove 311 is the same as the cross-sectional shape of the end of the baffle 32, so as to better match the end of the baffle 32.

[0058] The material of the baffle 32 may be bluestone.

[0059] In some embodiments, Figure 4As shown, the baffle 32 has a hollow structure, which makes the baffle 32 more beautiful.

[0060] The structure of the retaining wall body 1 is described in detail below:

[0061] The first retaining wall body 11 may be connected to the second retaining wall body 12 only at the top end, may be connected to the second retaining wall body 12 only at the bottom end, or may be connected to the second retaining wall body 12 at both the top end and the bottom end.

[0062] In some embodiments, Figure 2 As shown, the top and bottom ends of the first retaining wall body 11 are both connected to the second retaining wall body 12 , and the first retaining wall body 11 and the second retaining wall bodies 12 at both ends can be cast.

[0063] Specifically, the end of the first retaining wall body 11 facing the second retaining wall body 12 is roughened to have a concave structure, so that the construction surfaces of the first retaining wall body 11 and the second retaining wall body 12 are more firmly bonded.

[0064] In at least one embodiment, the material of the first retaining wall 11 is C30 concrete, and the material of the second retaining wall 12 is rubble concrete, and the above materials can be directly obtained.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
