Description

Technical Field

[0001] The utility model belongs to the technical field of roadbed construction, in particular to a retaining wall facing structure. Background Art

[0002] A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. It has the characteristics of fast construction speed, simple process, relatively low requirements for the foundation, and small footprint. It is mainly composed of a wall back, wall surface, base, wall top, and wall heel.

[0003] The wall surface usually adopts a veneer structure, which is an important component of the reinforced earth retaining wall. Its function is to support the decorative wall back. The existing common veneer structure usually uses stone for simple masonry, which is unstable.

[0004] Furthermore, the concepts of "shun" and "ding" are introduced in the masonry method of the veneer structure. Bricks placed in the direction of the building's width are called "shun" bricks, and bricks placed in the direction of the building's depth are called "ding" bricks, including full-shun, one-shun and one-ding, plum blossom-ding, three-shun and one-ding, and full-ding. Compared with the above simple splicing structure, the advantages are: the staggered joints between the layers of bricks are firm, the wall has good integrity, the operation changes little, it is easy to master, and the wall surface is also easy to control to be straight during masonry.

[0005] For example, the Chinese utility model patent with patent announcement number CN202559376U and announcement date 2012.11.28 discloses a municipal road structure along the river under an elevated bridge, with prefabricated T-shaped piles, concrete foundation, retaining wall, drainage holes, facing, concrete top plate, filter bag, backfill gravel, bubble mixed lightweight soil casting section, earth excavation line, bank protection, and foot protection.

[0006] The general structural principle of the municipal road structure along the river under the viaduct in this utility model patent is as follows: a concrete foundation is provided at the bottom of the retaining wall, prefabricated T-shaped piles are driven under the foundation, a facing is provided on the side of the retaining wall facing the bank, one or more drainage holes inclined toward the inner side of the river channel are provided in the retaining wall, a concrete top plate is provided on the top of the retaining wall, backfill gravel is provided on the back of the retaining wall, an anti-filter bag is provided on the end of the drainage hole facing the backfill gravel, and a bubble mixed lightweight soil casting section is provided on the back of the backfill gravel and above the foundation casting excavation line. Combined with the characteristics of light construction equipment and good protective performance of prefabricated T-shaped piles, and light soil of bubble concrete and convenient construction, the soil pressure on the inner side of the retaining wall can be effectively reduced, and the construction process, the cyclic changes in the river water level and the deformation of the bridge piers toward the inner side of the river channel after the road operation can be effectively controlled.

[0007] However, in actual use, the riverside municipal road structure under the viaduct still has at least the following two shortcomings, in other words, which are the technical problems to be solved by the present utility model.

[0008] 1. The veneer structure adopts M10 mortar-laid coarse aggregate stone, the joints adopt flat joints, and the laying adopts three straight and one straight. Therefore, there is a lack of necessary connection between the straight stone and the straight stone, and the stability of the veneer structure is relatively poor;

[0009] 2. The facing structure itself does not have drainage function, and the drainage method of the retaining wall is only a separately set drainage hole, and the drainage and water discharge capacity is far from enough.

[0010] Therefore, in summary, there is an urgent need for a new retaining wall facing structure with stable facing stacking and drainage function. Utility Model Content

[0011] The utility model provides a retaining wall facing structure, which can achieve the following by arranging the following stone units, the following stone units and the following stone units interlock with each other and are used to support the retaining wall after being stacked, so that the integrity is stronger, the interlocking between the following stone units and the following stone units is tighter, the stability is better, and the following stone units can be assembled according to the on-site environment, and the installation is flexible and convenient; 2. The following stone units and the following stone units are provided with drainage holes, so that the water in the drainage pipe and the retaining wall can be discharged in time, the drainage capacity is better, and the structural stability and the use safety of the retaining wall are increased.

[0033] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] As attached Figure 1-7As shown, a retaining wall facing structure includes a longitudinal stone unit 1 and a longitudinal stone unit 2 that are engaged with each other, and drainage holes 3 arranged on the longitudinal stone unit 1 and / or the longitudinal stone unit 2.

[0035] In this embodiment, if Figure 7 As shown, first of all, before construction, the retaining wall foundation is excavated and the foundation bearing capacity test is carried out. The next step of construction can be carried out only after the bearing capacity and specifications meet the design requirements. Otherwise, the over-excavation and filling method can be used for processing. After the excavation is completed, the cushion layer is poured, and the thickness and grade are required to meet the design requirements. After that, the Shunshi unit 1 and the Dingshi unit 2 are laid one layer of mortar at a time. The mortar adopts M20. The Shunshi unit 1 and the Dingshi unit 2 are arranged by a one-Ding-one-Shun masonry method to ensure the integrity with the retaining wall. The installation height should not be greater than 1.5 meters at a time. The retaining wall a is erected with a steel formwork, and then concrete is poured. The pouring height should not be greater than 1.5m. Repeat the above process to circulate each layer of concrete until the design elevation.

[0036] In addition, the drainage pipe b needs to be arranged in advance in the retaining wall a to facilitate the drainage of the accumulated water in the three-dimensional composite drainage network c near the soil layer d to the outside of the retaining wall, thereby playing a basic drainage role.

[0037] In addition, the straight stone unit 1 and the Ding stone unit 2 are interlocked and stacked to form a structurally stable veneer structure. The Ding stone unit 2 penetrates into the retaining wall a. During construction, after the straight stone unit 1 and the Ding stone unit 2 are installed, concrete is poured to form the retaining wall a. The straight stone unit 1 and the Ding stone unit 2 can play a shaping and supporting role for the retaining wall a, reduce the difficulty of construction, and at the same time strengthen the connection strength between the veneer and the retaining wall a.

[0038] Finally, the drainage holes 3 are arranged on the Shunshi unit 1 and / or Dingshi unit 2, and the water to be discharged by the drainage pipe b can be discharged through the drainage holes 3. At the same time, in addition to the drainage holes 3 arranged corresponding to the drainage pipe b, part of the accumulated water in the retaining wall a can also be discharged, so that the facing structure has better drainage and water discharge capabilities, which is not limited to the setting of the drainage pipe b, increases the structural stability of the retaining wall, and ensures the safety of the retaining wall.

[0039] The stone unit 1 includes a stone block 101 and slots 102 arranged on both side ends of the stone block 101 .

[0040] In this embodiment, the stone block 101 is placed in the width direction of the retaining wall, and a slot 102 for inserting the stone unit 2 is provided on the stone block 101, so that the connection between the stone unit 1 and the stone unit 2 is stable and the integrity is better.

[0041] The stone unit 2 includes a stone block 201 and protruding strips 202 arranged on both sides of the stone block 201 and used to be embedded in the card slot 102.

[0042] In this embodiment, the stone block 201 is placed in the depth direction of the retaining wall, and the protruding strip 202 is used to embed the slot 102. The stone block 101 and the stone block 201 can be prefabricated in advance or made on site, with strong flexibility. They are usually made of concrete, and other materials such as stone can also be used according to needs. Taking concrete as an example, the strength of the stone block 101 and the stone block 201 is not less than C25. There are mainly two specifications: 50×30×30 stone and 60×30×20 stone, some of which have drainage holes 3 reserved. For the convenience of transportation and installation, hoisting steel bars can be reserved inside the stone block 101 and the stone block 201.

[0043] The stone unit 1 further includes slots 103 and transverse strips 104 arranged on the upper and lower end surfaces of the stone block 101 .

[0044] In this embodiment, the grooves 103 and the transverse strips 104 are respectively arranged on the upper and lower end surfaces of the shale block 101. Since the shale unit 1 is laid with a layer of mortar, the grooves 103 and the transverse strips 104 can be well combined with the mortar, thereby increasing the connection strength between the upper and lower shale units 1 and the ore units 2, thereby increasing the integrity.

[0045] The stone unit 2 includes a groove 203 and a protruding column 204 arranged on the upper and lower end surfaces of the stone block 201.

[0046] In this embodiment, similarly, the grooves 203 and the protruding columns 204 have the same function as the slots 103 and the transverse strips 104, which are used to increase the integrity and strength of the veneer structure.

[0047] The retaining wall facing structure further comprises a dust cover unit 4 which is arranged on the straight stone unit 1 and / or the Ding stone unit 2 and is used to cover the drainage hole 3 .

[0048] In this embodiment, the function of the dust cover unit 4 is to prevent the mud and sand on the outside of the retaining wall facing structure from flowing into the drainage hole 3, thereby blocking the drainage hole 3 and affecting the aesthetics of the retaining wall facing structure.

[0049] The dust cover unit 4 includes a dust cover 401 and a hinge column 402 disposed on the dust cover 401 and used to connect the straight stone block 101 and the straight stone block 201 .

[0050] In this embodiment, the dust cover 401 is movably connected to the down stone block 101 and the down stone block 201 through a hinge column 402, and is used to cover the drainage hole 3. When there is water accumulated in the drainage hole 3, it can be directly discharged. When there is no water accumulation, it can prevent external dust from entering the drainage hole 3 and causing blockage. At the same time, when cleaning is needed, only the dust cover 401 needs to be lifted.

[0051] The retaining wall facing structure further comprises a pressing block 5 arranged on the top of the longitudinal stone block 101 and the lateral stone block 201 .

[0052] In this embodiment, the pressing block 5 is arranged on the top of the straight stone block 101 and the T-stone block 201 to press the veneer so that the bearing capacity of the veneer is higher.

[0053] The retaining wall facing structure also includes an inverted L-shaped block 6 which is arranged on the pressing block 5 and is used to engage with the retaining wall a.

[0054] In this embodiment, the inverted L-shaped block 6 is integrated with the pressing block 5, which increases the connection strength between the pressing block 5 and the retaining wall a, and prevents the longitudinal stone block 101 and the diagonal stone block 201 from tilting outward, thereby ensuring the stability of the veneer.

[0055] The retaining wall facing structure also includes a vertical support plate 7 arranged on the exposed surfaces of the Shunshi unit 1 and Dingshi unit 2.

[0056] In this embodiment, the vertical support plate 7 is arranged on the outside of the veneer to further reinforce the Shunshi unit 1 and the Dingshi unit 2. The vertical support plate 7 is arranged starting from the ground e and can be strengthened by being arranged at intervals.

[0057] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
