[0003] However, when it is not possible to cut grooves and slope for construction, how to improve the construction strength of the river retaining wall, how to improve the construction efficiency, and at the same time, to meet the growing aesthetic needs of the river retaining wall and the needs of ecological civilization construction, these are all necessary issues that need to be solved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an integrated structure of cast-in-place pile support and stone-built ecological retaining wall, which meets the strength requirements of the river retaining wall, completes the construction content quickly and efficiently, and takes into account the ecological treatment and beautification effect of the river retaining wall.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cast-in-place pile support and stone ecological retaining wall integrated structure, comprising a stone wall, a plurality of cast-in-place piles arranged in a row are arranged on one side of the back of the stone wall, a concrete interlayer is arranged between the cast-in-place piles and the stone wall, a concrete bottom plate is arranged below the stone wall, and a concrete cap is arranged above the stone wall;

[0007] The stone wall includes blocks, isolation rings, masonry layers and ecological layers. The isolation rings are sleeved on the outside of the blocks and close to the front side of the stone wall. Between the blocks of two adjacent layers, only one of the blocks is provided with an isolation ring. The isolation rings isolate the interlayer between the two adjacent layers of blocks. The interlayer close to the front side of the stone wall is the ecological layer, and the interlayer close to the back side of the stone wall is the masonry layer.

[0008] Furthermore, the stone masonry wall comprises two layers of transverse block stone flat layers and longitudinal block stone flat layers arranged adjacent to each other, wherein the blocks in the transverse block stone flat layers or the longitudinal block stone flat layers are provided with isolation rings.

[0009] Furthermore, the blocks and the isolation rings are in a one-to-one correspondence.

[0010] Furthermore, the block stone is provided with an annular mounting groove at the sleeve isolation ring.

[0011] Furthermore, the isolation ring is made of rubber; and there is an interference fit between the isolation ring and the stone block.

[0012] Furthermore, the ecological layer is paved with a soil layer, which also includes planting soil, organic matter, granular agents, grass seeds and water, which are mixed into a paste-like spraying material by a mixer.

[0013] Furthermore, the paste-like spraying material is sprayed onto the outside of the ecological layer through a spraying machine.

[0014] Furthermore, the concrete base plate is a cast reinforced concrete plate, and the cast-in-place piles are connected to the steel bars in the concrete base plate by drilling and planting steel bars; the concrete top plate is a cast reinforced concrete plate.

[0015] Furthermore, the masonry layer includes cement and mortar in a ratio of 1:2 to 1:4.

[0016] Furthermore, the isolation ring is arranged 8 to 12 cm away from the front side of the stone wall.

[0017] The present invention can be constructed by the following method:

[0018] (1) Construction of supporting piles: After surveying and laying out, holes are drilled one by one, and then steel cages are hoisted in and concrete is poured to form cast-in-place pile supporting walls;

[0019] (2) Digging trenches: Make sure the inside of the piles are completely exposed, clean up the bonding soil at the exposed part of the piles, clean up the loose soil between the piles, and chisel off the outer protective layer at the top of the inner arc of the pile foundation to make the concrete bond with it more firmly in the later stage.

[0020] (3) Casting of concrete base slab: At the designed height of the concrete base slab, holes are drilled and steel bars are planted in the cast-in-place piles, which are then tied and connected to the steel bars in the concrete base slab, and then the concrete base slab is cast;

[0021] (4) Construction of stone masonry walls: ① Reserve a concrete interlayer, ② Customize isolation rings and match the isolation rings to the corresponding stones one by one, ③ Lay a masonry layer on the concrete base plate, and then lay the first layer of stones with isolation rings, ④ Lay masonry materials made of cement and mortar on the first layer of stones, lay the soil layer on the ecological layer, and then start to lay the second layer of stones without isolation rings, and the third layer of stones with isolation rings, and repeat the operation. In addition, the height is increased by 1~1 When the distance is .5m, timely cover and maintain, and when the mortar strength in the masonry material reaches 4-6 MPa, concrete is poured into the concrete interlayer; wherein, the two adjacent layers of blocks are respectively a horizontal block flat layer and a vertical block flat layer, that is, "one horizontal and one vertical"; in this way, in order to form a jagged connection structure between the concrete interlayer and the blocks, the connection strength can be effectively improved, thereby improving the tensile strength of the stone masonry wall; at the same time, the staggered joints between the two adjacent layers of blocks can also effectively improve the tensile strength of the stone masonry wall;

[0022] (5) Casting concrete capping: After the stone wall reaches the specified height, cast reinforced concrete capping, which serves as the base of the railing;

[0023] (6) Improve the ecological layer: add water to planting soil, organic matter (rice husks, fertilizers, etc.), granular agents, grass seeds, etc., use a mixer to mix them into a paste-like spraying material, and spray them on the outside of the ecological layer through a sprayer; use non-woven fabric to cover the stone wall, and use a sprayer to spray water to keep it moist and maintain it. After the grass seeds germinate, remove the non-woven fabric covering layer and continue to spray water for maintenance as needed.

[0024] Furthermore, in step (4) ④, when pouring the concrete interlayer, the concrete construction joint is treated, that is, the upper layer of concrete is poured after roughening; in order to make the bond between the concrete and the pile foundation more firmly, reinforcement can be planted in the cast-in-place pile.

[0025] Furthermore, in step (4) ④, in order to prevent the stone wall from deforming during the pouring of the concrete interlayer, a temporary wall support is made and removed after the concrete has finally set.

[0026] Furthermore, in step (6), the inner diameter of the nozzle of the shotcrete machine is 0.5-1 cm.

[0027] Beneficial effects: The integrated structure of the cast-in-place pile support and the stone ecological retaining wall of the present invention combines the support structure with the main body of the project, and completes the construction content quickly and efficiently; ecological beautification is also integrated, while taking into account the ecological treatment and beautification effect of the river retaining wall.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below with reference to specific embodiments.

[0036] Embodiment 1

[0037] Figure 1 A structure of a cast-in-place pile 7 support and a stone masonry ecological retaining wall is shown, comprising a stone masonry wall 4, a plurality of cast-in-place piles 7 arranged in a row are arranged on the back side of the stone masonry wall 4, a concrete interlayer 2 is arranged between the cast-in-place piles 7 and the stone masonry wall 4, a concrete bottom plate 5 is arranged below the stone masonry wall 4, and a concrete cap 3 is arranged above the stone masonry wall 4;

[0038] The stone wall 4 includes blocks, an isolation ring 41, a masonry layer 411 and an ecological layer 412. The isolation ring 41 is sleeved on the outside of the blocks and close to the front side of the stone wall 4. Between the blocks of the upper and lower adjacent layers, only one of the blocks is provided with an isolation ring 41. The isolation ring 41 isolates the interlayer between the upper and lower adjacent layers of blocks. The interlayer close to the front side of the stone wall 4 is the ecological layer 412, and the interlayer close to the back side of the stone wall 4 is the masonry layer 411.

[0039] The stone masonry wall 4 includes a horizontal block stone paving layer 42 and a vertical block stone paving layer 43 which are arranged adjacent to each other, wherein isolation rings 41 are arranged on the blocks in the horizontal block stone paving layer 42 (i.e., the block straight paving layer) or the vertical block stone paving layer 43 (the block diagonal paving layer).

[0040] The blocks of stone correspond to the isolation rings 41 one to one; that is, in a layer of blocks of stone with isolation rings 41, each block of stone is covered with an isolation ring 41. If the blocks of stone laid in a straight line are covered with isolation rings 41, a larger isolation ring 41 is selected; if the blocks of stone laid in a straight line are covered with isolation rings 41, a smaller isolation ring 41 is selected.

[0041] The block is provided with an annular installation groove 413 at the sleeve isolation ring 41, so that the customized rubber isolation ring 41 can be smoothly installed in the installation groove 413 to prevent the rubber isolation ring 41 from moving. The block is provided with an annular installation groove 413 in the longitudinal direction, and the block is cut with an annular installation groove 413 in the transverse direction, and the corresponding rubber isolation ring 41 is installed in the installation groove 413.

[0042] The isolation ring 41 can be made of many materials, for example, rubber, metal, composite materials, etc., among which a material with a certain elasticity is preferably used, and rubber material is the best. The rubber material has a certain elasticity, wear resistance and corrosion resistance. On the one hand, it is easy to put on the stone block. On the other hand, when laying the upper stone block, the stone block can dissipate part of the impact force at the moment of contacting the rubber isolation ring 41, which has a certain buffering effect, reduces the impact on the mortar, and increases the stability of the stone block falling. Moreover, when fine-tuning the position of the stone block, it acts as an elastic fulcrum, which greatly improves the fine-tuning efficiency, thereby improving the masonry efficiency.

[0043] The isolation ring 41 and the stone block are in interference fit. Considering the elasticity of rubber, the customized size of the isolation ring 41 is slightly smaller than the calculated length, and the size is customized according to the actual size of the stone block.

[0044] The ecological layer 412 is paved with a soil layer, which also includes planting soil, organic matter, granular agent, grass seeds and water, which are mixed into a paste-like spraying material by a mixer. The paste-like spraying material is sprayed on the outside of the ecological layer 412 by a spraying machine.

[0045] The concrete bottom plate 5 is a cast reinforced concrete plate, flush with the riverbed 6, and the cast-in-place piles 7 are connected to the steel bars in the concrete bottom plate 5 by drilling and planting steel bars; the concrete top plate 3 is a cast reinforced concrete plate, and the concrete top plate 3 is flush with the riverbank ground 1. The integrated structure is conducive to improving the overall strength.

[0046] The masonry layer 411 includes masonry materials prepared with cement and mortar in a ratio of 1:2 to 1:4.

[0047] The isolation ring 41 is arranged 8-12 cm away from the front side of the stone wall 4 , that is, the depth of the ecological layer 412 is at least 8-12 cm, which can meet the initial growth needs of the vegetation in the ecological layer 412 .

[0048] Beneficial effects: The integrated structure of the cast-in-place pile 7 support and the stone-built ecological retaining wall of the present invention combines the support structure with the main body of the project, and the integrated structure greatly improves the overall strength; the rubber isolation ring 41 reduces the impact of masonry on the mortar, increases the stability of the falling stone blocks, and when fine-tuning the position of the stone blocks, it acts as an elastic fulcrum, greatly improving the fine-tuning efficiency, thereby improving the masonry efficiency, reducing the waste of mortar and masonry materials, and thus completing the construction content quickly and efficiently; ecological beautification is also integrated, while taking into account the ecological treatment and beautification effect of the river retaining wall.

[0049] Embodiment 2

[0050] This embodiment specifically illustrates the specific construction method of the present invention, and the parts not mentioned in the structure are as described in the above embodiment.

[0051] (1) Construction of supporting pile rows: After surveying and setting out, the pile foundation holes 8 are drilled one by one, and then the steel cage is hoisted in and concrete is poured to form a supporting wall of cast-in-place piles 7;

[0052] (2) Digging trenches: Make the inner side of the cast-in-place pile 7 completely exposed, clean up the bonding soil at the exposed part of the cast-in-place pile 7; clean up the loose soil between the piles; chisel off the outer protective layer at the top of the inner arc of the pile foundation to make the later concrete bonded to it more firmly;

[0053] (3) Casting the concrete base 5: At the designed height of the concrete base 5, the cast-in-place piles 7 are drilled and reinforced, and tied to the steel bars in the concrete base 5, and then the concrete base 5 is cast;

[0054] (4) Construction of stone masonry wall 4: ① reserve concrete interlayer 2, ② customize isolation ring 41, and match isolation ring 41 with corresponding stone blocks one by one, ③ lay masonry layer 411 on concrete base plate 5, and then lay the first layer of stone blocks with isolation ring 41, ④ lay masonry materials prepared by cement and mortar on the first layer of stone blocks, lay soil layer on ecological layer 412, and then start to lay the second layer of stone blocks without isolation ring 41, and lay the third layer of stone blocks with isolation ring 41, and repeat the operation in this way, and the height is increased every liter. When the height is 1-1.5m, timely cover and maintain, and after the mortar strength in the masonry material reaches 4-6mpa, concrete is poured into the concrete interlayer 2; wherein, the two adjacent layers of blocks are respectively a horizontal block paving layer 42 and a longitudinal block paving layer 43, that is, "one horizontal and one vertical"; in this way, in order to form a jagged connection structure between the concrete interlayer 2 and the blocks, the connection strength can be effectively improved, thereby improving the tensile strength of the stone masonry wall 4; at the same time, the staggered joints between the two adjacent layers of blocks can also effectively improve the tensile strength of the stone masonry wall 4;

[0055] (5) Casting concrete capping 3: After the stone masonry wall 4 reaches the specified height, reinforcement is planted in the pile foundation, the two are tied together, and then the reinforced concrete capping 3 is cast, which serves as the base of the railing;

[0057] (7) When the strength of the stone wall 4 reaches the standard requirements, backfill the earth and stone behind the wall in time.

[0058] In step (4) ④, when pouring the concrete interlayer 2, the concrete construction joint is treated, that is, the upper layer of concrete is poured after roughening; in order to make the bond between the concrete and the pile foundation more firmly, reinforcement can be planted in the cast-in-place pile 7.

[0059] In step (4) ④, in order to prevent the 4 surfaces of the stone wall from deforming during the pouring of the concrete interlayer 2, a temporary wall support is made and removed after the concrete has finally set.

[0060] In step (6), the inner diameter of the nozzle of the shotcrete machine is 0.5~1 cm.

[0061] The beneficial effects of the present invention are as follows: the bored piles 7 and the concrete base plate 5 are connected as a whole by drilling and embedding reinforcement, the blocks of the stone wall 4 are "one straight and one straight" at the connection with the concrete interlayer 2, so that the stone wall 4 and the concrete interlayer 2 are staggered, thereby increasing the connection area between the two and increasing the connection strength, and the concrete interlayer 2 is embedded with reinforcement in the bored piles 7, so that the bond between the concrete interlayer 2 and the pile foundation is more firmly bonded, thereby making the connection between the stone wall 4 and the pile foundation more stable; the concrete capping 3 is cast as a whole with the pile foundation and the stone wall 4, so that the pile foundation, the concrete base plate 5, the stone wall 4, the concrete interlayer 2, and the concrete capping 3 are interconnected as a whole, and the overall strength is greatly improved, meeting the strength requirements of the river retaining wall.

[0062] In summary, the present invention meets the strength requirements of river retaining walls, the growing aesthetic requirements, and the requirements for ecological civilization construction. At the same time, the present invention can also be used in other construction projects.
