Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a gravity retaining wall. Background Art

[0002] Since highways are generally far from urban areas and the environment beside highways is complex, especially in mountainous areas, retaining walls are needed to intercept mountain soil beside highways. Retaining walls refer to structures that support roadbed fill or hillside soil and prevent fill or soil from deforming and becoming unstable. In the cross section of the retaining wall, the part that is in direct contact with the supported soil is called the wall back; the part facing the air opposite to the wall back is called the wall surface; the part that is in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the wall top; the front end of the base is called the wall toe; and the rear end of the base is called the wall heel. There are many types of retaining walls, mainly including gravity retaining walls, anchored retaining walls, thin-walled retaining walls, reinforced soil retaining walls, etc. Among them, gravity retaining walls use mortar-laid stone or rough stone retaining walls as retaining projects and are widely used in engineering construction. Because of its simple construction, local materials can be used, and low cost, it is still an important engineering measure in engineering construction, especially for some low-grade roads and highways with special requirements. Due to factors such as changes in the site environment around the retaining wall, it is inevitable that it will have a certain degree of defects: the sliding force in the front or rear rock and soil body increases due to external forces, causing landslides, making the retaining wall foundation unstable and causing displacement and sliding. The stability of the retaining wall is poor, increasing adverse defects. Utility Model Content

[0078] Example 1

[0079] like Figure 1-4 As shown, a gravity retaining wall provided in this embodiment includes a wall 1, a tie rod 5, a reinforcement plate 6, and a connection structure; the tie rod 5 is used to apply tension to the wall 1; the reinforcement plate 6 is used to reinforce the structure of the wall 1; the connection structure is used to strengthen the structure between the tie rod 5 and the wall 1; the tie rod 5 applies tension along the length direction of the wall 1 away from the back of the wall, thereby fixing the wall 1 on the rock and soil 3.

[0080] In this embodiment, the pull rod 5 provides an inward force along the length direction of the wall 1. The friction force generated by the wall 1 and the slope on the side of the rock and soil body 3 due to its own gravity serves as a reaction force. The pull rod 5 forms a reaction force structure, so that the action force and the reaction force are balanced to stably set the wall 1 on the slope of the rock and soil body 3, reduce the occurrence of position displacement of the wall 1 due to increased sliding force under the rock and soil body 3, and solve the pathological disasters caused by insufficient anti-slip ability of the retaining wall.

[0081] In this embodiment, the part of the cross section of the wall 1 that is in direct contact with the rock mass 3 is called the wall back (i.e. Figure 1 As shown, the right side wall of the wall 1), the part opposite to the back of the wall and facing the air becomes the wall surface (i.e. Figure 1 As shown, the left side wall of the wall 1) directly contacts the foundation 4 and becomes the base 2 (i.e. Figure 1 As shown, the bottom of the wall 1), the top surface of the wall 1 opposite to the base 2 becomes the wall top (i.e. Figure 1 As shown, the top of the wall 1). And, the highest point of the application is flush with the ground.

[0082] In this embodiment, there are at least two walls 1, which are symmetrically fixed on the rock mass 3. The tie rod 5 is set to one or more, and the multiple tie rods 5 are arranged in sequence and equidistantly along the height direction of the wall 1. One end of the tie rod 5 is set in the rock mass 3, and the other end of the tie rod 5 passes through the wall 1 and is set on the reinforcement plate 6. The tie rod 5 can be preferably set to be inclined downward, and the gap between the tie rod 5 and the wall 1 and the rock mass 3 is poured with concrete to form a concrete connecting layer 11, which is more convenient for grouting. And the cross-section of the wall 1 is square, rectangular or trapezoidal. In this embodiment, the cross-section of the wall 1 is preferably trapezoidal (such as Figure 1 as shown).

[0083] In this embodiment, the connection structure includes a connection rod 7, a connection rib 8, and a connection piece 9; the connection rod 7 is vertically arranged on the tie rod 5; one or more connection ribs 8 are vertically arranged on the connection rod 7 along the axial direction of the tie rod 5; the connection rib 8 is inserted into the wall 1; concrete is poured into the gap between the connection rod 7 and the connection rib 8 and the reinforcement plate 6 and the wall 1 to form a concrete connection layer 11; the connection piece 9 is connected to the connection between the connection rod 7 and the tie rod 5 and the connection rib 8. To ensure the connection strength, the number of the connection rods 7 is preferably several, at least two, and the multiple connection rods 7 are arranged vertically on the tie rod 5 and tied by the connection piece 9. The connection piece 9 is preferably iron wire, and the multiple connection ribs 8 are tied and fixed to the connection rod 7 by iron wire.

[0084] In this embodiment, the connection structure is provided in multiple places, mainly including between the wall 1 and the reinforcement plate 6 and between the wall 1 and the rock and soil body 3. The connection rod 7 and / or the connection rib 8 may preferably be a steel bar.

[0085] In this embodiment, after the wall 1 is butt-jointed with the reinforcement plate 6 / rock mass 3, the connection between the two is completed through a connecting structure. After the connection, the connecting rods 7 and the connecting ribs 8 are embedded by pouring concrete, and the poured concrete forms a concrete connecting layer 11. Since the two are connected by the connecting rods 7 and the connecting ribs 8, the integrity of the wall 1 and the reinforcement plate 6 / rock mass 3 is enhanced, and the structure of the connection is strengthened.

[0086] In this embodiment, the reinforcement plate 6 can be a reinforced concrete panel or a frame structure. Since the load-bearing methods of the reinforced concrete panel and the frame structure are different, the reinforced concrete structure is jointly loaded by its beams, plates, columns, and walls, and the frame structure is loaded by the frame weight composed of its beams and columns, and the wall is a filling material and does not bear the load. For this field, in order to maximize the high-strength state of this application, the reinforcement plate 6 is preferably a reinforced concrete structure.

[0087] The reinforcing plate 6 is arranged on the inclined surface of the wall 1, which effectively protects the outer inclined surface of the wall 1, strengthens the inclined surface strength, and can also prevent stones from falling directly along the inclined surface of the wall 1, thereby improving the retaining effect and safety of the wall 1.

[0088] In this embodiment, the pull rod 5 can be a steel bar, a steel pipe or an anchor rod structure.

[0089] This embodiment further includes a base 2 disposed at the bottom of the wall 1 for supporting the retaining wall as a whole.

[0090] This embodiment also includes a positioning groove 10 provided in the rock mass 3, which is used to position the bottom end of the tie rod 5. In order to further increase the connection strength and connection stability between the tie rod 5 and the rock mass 3, a positioning groove 10 is provided at the bottom of the tie rod 5. The positioning groove 10 is an annular structure. The positioning groove 10 cooperates with the lower end of the tie rod 5 to increase the radial stability of the tie rod 5. Under the action of the connecting rod 7, the connecting rib 8 and the concrete connecting layer 11, the axial stability and connection strength of the wall 1 and the reinforcement plate 6 / rock mass 3 are increased.

[0091] In this embodiment, the installation position of the middle tie rod 5 among the plurality of tie rods 5 is set at a position above the center of gravity of the wall 1 (while also ensuring that adjacent tie rods 5 are arranged equidistantly) to ensure that the anti-overturning moment is greater than the overturning moment, thereby preventing the wall 1 from collapsing due to overturning instability.

[0092] In summary, the gravity retaining wall provided by the utility model can ensure its stability and safety.

[0093] Example 2

[0094] This embodiment is basically the same as the first embodiment, except that the connection structure of the first embodiment is improved.

[0095] like Figure 5-6 As shown, the connecting rod 7 in the connecting structure is composed of a positioning rod 12 and a limiting ring 13. The positioning rod 12 is vertically penetrated and arranged on the pull rod 5; the limiting ring 13 is arranged on the pull rod 5; there are at least two limiting rings 13, which are arranged on the side wall of the pull rod 5 to limit the positioning rod 12.

[0096] In this embodiment, the positioning rod 12 passes through the pull rod 5 and is fixed by cooperating with the limiting ring 13. At least two limiting rings 13 are used in conjunction with one positioning rod 12, and the limiting ring 13 clamps the pull rod 5. The connecting rib 8 can still be tied with the connecting piece 9 (iron wire) described in Example 1, and can also be connected by nuts, threads, welding or other connection methods.

[0097] In summary, the connection structure not only connects multiple adjacent walls 1 into one, but also casts the concrete embedded connection structure to strengthen the overall structure of the present application, so that the present application can be stably set on the rock and soil body 3 with strong firmness.

[0098] Example 3

[0099] This embodiment is basically the same as Embodiment 1, except that:

[0100] like Figure 7-10 As shown, this embodiment also includes a bottom pile 14, which is used to improve the resistance of the wall 1. In this embodiment, the bottom pile 14 is arranged along the height direction of the wall 1 (vertically arranged); the upper part of the bottom pile 14 penetrates into the interior of the wall 1, and is pre-embedded with concrete to form a concrete connection layer 11. The bottom pile 14 is arranged along the height direction of the wall 1, and the upper part of the bottom pile 14 penetrates into the interior of the wall 1, and is pre-embedded with concrete to form a concrete connection layer 11. Specifically, the bottom pile 14 limits the length direction of the wall 1, and even if the rock and soil body 3 slides down / collapses, the wall 1 will not be displaced, slid, or overturned. Moreover, the bottom pile 14 is a steel pipe pile with a strong supporting force, which can ensure the stable installation of the wall 1.

[0101] This embodiment also includes a support assembly arranged in the middle of the bottom pile 14, which is used to support and balance the wall 1. The support assembly includes an outer support ring 15 and an inner support block 16; the outer support ring 15 is embedded in the base 2, which is used to limit the bottom pile 14 in the vertical direction; the inner support block 16 includes a plurality of inner support blocks 16, which are arranged along the circumferential direction of the bottom pile 14, and are used to support the wall 1 in the vertical direction to prevent sinking. In addition, it also includes a fixed column 17 arranged at the upper and lower parts of the bottom pile 14, which is used to stabilize the soil and strengthen the grouting connection, so that the stability of the vertical state of the bottom pile 14 can be guaranteed to the greatest extent; the two ends of the fixed column 17 include a connecting part and a stabilizing part, the connecting part is arranged on the bottom pile 14, and the stabilizing part is arranged in the soil. The diameter from the connecting part to the stabilizing part gradually decreases, and the stabilizing part is pointed and finally fixed in the soil through the concrete connecting layer 11. Specifically, the bottom pile 14 takes the stable support of the wall 1 as a premise through the fixed column 17, and the inner support block 16 supports the bottom of the wall 1, plays an effective supporting role to prevent it from sliding down due to soil collapse; even after long-term use, the bottom pile 14 has a downward sinking force, and the inner support block 16 is arranged on the inner side of the support ring. Even if the bottom pile 14 has a downward trend, the inner support block 16 is limited by the support ring, so that the bottom pile 14 cannot continue to sink, thereby ensuring stability.

[0102] In this embodiment, the side of the inner support block 16 that contacts the bottom pile 14 forms an arc groove to facilitate the fit with the bottom pile 14 .

[0103] In summary, this embodiment adopts bottom piles 14 to improve the resistance effect, so that the wall 1 is stably set on the rock and soil body 3, and the stability can be guaranteed by setting the bottom piles 14 alone; for long-term considerations, the stability can be greatly improved by adding bottom piles 14 and combining with embodiment 1, which is more practical.

[0104] Example 4

[0105] This embodiment is basically the same as Embodiment 1, except that:

[0106] When the cross-sectional design of the retaining wall is too small or the construction quality is poor, the shear strength of the retaining wall structure will be reduced and disease will occur. In this embodiment, based on the reinforcement of Example 1, a grouting process is also used to enhance the shear resistance of the retaining wall, and the structure of the diseased retaining wall can be remedied, which is a convenient and fast construction measure.

[0107] Specifically: Fig.11As shown, in this embodiment, with the help of drilling equipment, a conduit hole is punched inward from the wall surface of the vertical wall 1, and a grouting conduit is inserted into the conduit hole using a pipe inserting device, and concrete is injected into the grouting conduit. After a certain solidification time, a reinforcement column 18 is formed. Since there are tiny structural voids in the soil layer of the wall 1, and the construction inevitably causes a certain disturbance to the soil layer, larger voids and cracks are caused, which seriously affects the shear resistance of the wall 1. If the wall 1 is grouting, the concrete slurry can fill the voids and cracks in the soil layer. When the grouting pressure gradually increases, the soil layer around the voids and cracks is further compacted, thereby improving the shear resistance of the wall 1 in the foundation project.

[0108] 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.
