Description

Technical Field

[0001] The present invention relates to the field of assembled landscape architecture, and in particular to a composite ecological landscape assembled retaining wall component prefabrication device and a construction method. Background Art

[0002] At present, the most commonly used retaining walls in my country's infrastructure projects are gravity retaining walls. The disadvantage of gravity retaining walls is that the masonry volume is huge and they rely entirely on their own weight to support the lateral pressure of the roadbed. Calculated based on the common first-level slope of 8.0m, the masonry volume of the gravity retaining wall is 8 times that of the ecological retaining wall. During the construction process, secondary steel bar tying and concrete pouring are required, and the concrete prefabrication rate is only 80%; the drainage windows of the existing retaining walls are located behind the vegetation board and are connected to the roadbed filler. When there is abundant rainfall during the rainy season, the drainage windows may cause damage or hollowing of the roadbed. Excessive rainfall may also cause the destruction of green plants, and the above problems have also multiplied the burden on the environment.

[0003] As we all know, the current retaining wall is constructed by cast-in-place mode. The cast-in-place mode requires a lot of preparations and is also subject to various practical factors, resulting in slow construction progress. Therefore, there is a lack of a prefabricated retaining wall that can be decomposed into multiple components and assembled on site. Summary of the invention

[0004] The invention provides a composite ecological landscape assembled retaining wall component prefabrication device, which solves the problems of large masonry workload, high capital investment, environmental damage and long construction period.

[0005] In order to achieve the above object, the technical solution of the present invention is:

[0006] A composite ecological landscape assembled retaining wall component prefabrication device, characterized in that it includes: columns, greening pools, bottom plates, spiral corrugated holes, water receiving platforms, permeable retaining plates, cover plates and mortise and tenon structures;

[0007] The greening pool is arranged above the base plate, the columns are arranged on the left and right sides of the base plate, the mortise and tenon structures and the spiral corrugated holes are arranged on the columns, a permeable retaining plate is arranged on the rear side of the base plate, the water receiving platform is arranged on the rear side of the permeable retaining plate, and the cover plate is located above the columns.

[0015] Furthermore, a watering pipe is vertically provided on the right column.

[0016] Furthermore, a cover plate mortise is provided at the upper end of the cover plate, and a cover plate tenon is provided at the lower end.

[0017] Further, the following steps are included:

[0018] Step 1: Excavation of foundation pit

[0019] Before the retaining wall is constructed, the lines are measured and laid out according to the retaining wall design drawings, and then the foundation pit is excavated;

[0020] Step 2: Install the template

[0021] The template is installed according to the measurement and layout. The template uses a large steel template. The template crosses the tie rod to prevent the template from expanding.

[0022] Step 3: Pour the Concrete

[0023] The concrete is C30 concrete, which is transported by tank trucks and can be poured by pump trucks. Each layer is vibrated once until the concrete stops bubbling. The concrete is poured to the top surface of the formwork to ensure the flatness of the top surface. At least two finishing steps are used to ensure that there are no cracks on the surface.

[0024] Step 4: Install the first layer of components

[0025] Transport the required number of components for a retaining wall, clean the dirt or residue on the surface of the concrete foundation, lay out the lines to check whether the embedded position and height of the anchor meet the design requirements. If there is a small deviation, fine-tune it according to the majority obeying the minority, and then check the quality of the sleeve nut. The components are installed with the assistance of a crane, and the vertical tensioning holes are used as temporary lifting holes. Before construction, a lifting tool (8) is processed according to the characteristics of the vertical tensioning holes to lift the components. The first assembly part I type component is installed at the left end of the first layer, multiple first assembly part II type components are installed in the middle, and the first assembly part III type is installed at the right end;

[0026] Step 5: Install the second layer of components

[0027] The second layer components are second assembly part type I, second assembly part type II and second assembly part type III components. The second layer components are located on the upper part of the first layer. Before installing the second layer, the flatness of the first layer installation is carefully checked to ensure that the surface of the first layer is flat and correct when installing the second layer. The second assembly part type I component is installed at the left end, multiple second assembly part type II components are installed in the middle, and the second assembly part type III component is installed at the right end. The two layers of components are connected by vertical mortises and vertical tenons.

[0028] Step 6: Install the third layer of prefabricated components

[0029] The installation method of the third layer components is the same as that of the second layer components. To ensure safe and environmentally friendly construction, vertical tensioning is performed once every three layers of components are installed until the cover plate is installed on the top of the retaining wall and tensioning and grouting are performed again;

[0030] Step 7: Tension grouting

[0031] Grouting can be carried out only after tensioning is completed, and the grade of the grouting material should be the same as the strength of the component;

[0032] Step 8: Install the upper components

[0033] After the three-layer tensioning and grouting is completed, the upper tensioning component is installed. The third assembly part type I component is installed on the left end, and multiple third assembly part type II components are installed in the middle. The third assembly part type III component is located at the right end. The installation process and method are the same as the first assembly part.

[0034] Step 9: Cover Installation

[0035] After the installation of each component is completed, the cover plate is installed on the top of the retaining wall in sequence, and the cover plate is tensioned together with the components after installation;

[0036] Step 10: Longitudinal tensioning and grouting

[0037] After the overall structure of the retaining wall is assembled, longitudinal tensioning and longitudinal grouting are finally carried out.

[0038] Beneficial effects: The present invention provides a composite ecological landscape prefabricated retaining wall component prefabrication device, which adopts a prestressed tensioning system to reduce the amount of masonry and investment funds. The greening pool and permeable retaining board structure in the component can protect the roadbed and the green plants in the component, and also protect the ecological environment; the prefabricated retaining wall can be decomposed into a variety of components and can be assembled and constructed on site, thereby improving the construction efficiency.

DETAILED DESCRIPTION

[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] This embodiment provides a composite ecological landscape assembled retaining wall component prefabrication device, the specific contents are as follows:

[0059] like Figure 1-3 As shown, a composite ecological landscape assembled retaining wall component prefabrication device includes a column 1, a greening pool 2, a base plate 3, a tensioning system, a water receiving platform 5, a permeable retaining plate 6, a cover plate 9, a mortise and tenon structure, a concrete foundation and a ground anchor; before the construction of the retaining wall, the type of the retaining wall can be designed according to the drawings, whether it is a vertical retaining wall or an inclined retaining wall, and the foundation pit is constructed according to the type of the retaining wall. In this embodiment, a vertical retaining wall is preferably used, and columns 1 are arranged on the left and right sides of the component base plate 3. The column 1 is a solid structure and is the main force-bearing structure of the retaining wall. The existing column 1 is composed of prefabricated components combined into a template, steel bars are tied on site, and then poured into the mold again. During the installation process, secondary steel bar tying and concrete pouring are required, which is not in line with the current policy orientation, and the concrete prefabrication rate is only 80%. The column 1 in this component is prefabricated simultaneously with the overall component, the stress state is good, and the concrete prefabrication rate reaches 99%, which is in line with the current development trend.

[0060] The column 1 is provided with a spiral corrugated hole, which includes a vertical corrugated hole 4 and a longitudinal corrugated hole 11. The number of vertical corrugated holes 4 on each side column 1 is two, and each vertical corrugated hole 4 is provided with a vertical mortise 12 at the upper end and a vertical tenon 13 at the lower end. The vertical tenon 13 is provided with a through hole connected to the vertical corrugated hole. The diameter of each vertical corrugated hole 4 is 4 cm. When multiple components are stacked up and down, 1-3 anchor bars can be set in the interconnected vertical corrugated holes 4; the number of longitudinal corrugated holes 11 on each side column 1 is up to There is usually one. After the construction of the retaining wall is completed, the longitudinal prestressing is constructed according to the design. The rock mass or filling material is used as the anchoring section to form a whole with the retaining wall through anchor bars. The spiral corrugated hole is used as the prestressing tensioning hole of this component. The whole is spiral. During the grouting process, the slurry will rise or fall along the spiral shape, which will reduce the voids or slurry emptiness. The prestressing can effectively increase the anchoring degree between the components. The anchor bars of this retaining wall can be steel bars or steel strands. It is a system that connects the components together to bear the force as a whole.

[0061] The present component is reinforced as a whole by using a mortise and tenon structure. The mortise and tenon structure has different structural shapes according to the different positions of the retaining wall components. Specifically, it includes a vertical mortise and tenon, a transverse mortise and tenon, a longitudinal mortise eye 16 and an anchor block 20. Among them, both vertical and transverse are real and virtual cones, the vertical one is a cone, and the transverse one is a rectangular cone; the vertical mortise and tenon includes a vertical mortise eye 12 and a vertical tenon head 13. The width of the vertical tenon head 13 is smaller than the width of the inner diameter of the vertical mortise eye 12. The vertical mortise eye 12 is located at the upper end of the vertical corrugated hole 4, and the vertical tenon head 13 is located at the upper end of the vertical corrugated hole 4. At the lower end of the vertical corrugated hole 4, the vertical tenon 13 is provided with a through hole in the vertical direction, and the through hole is connected to the vertical corrugated hole for passing the vertically tensioned anchor bar. During the installation process, the vertical mortise 12 is at the bottom, and the vertical tenon 13 of the other component is at the top, and the vertical tenon 13 can be smoothly installed in place by only partially inserting the vertical mortise 12, which effectively solves the misalignment between the upper, lower, left and right components. The gap between the vertical mortise and tenon is connected to the vertical corrugated pipe. During the grouting process, the slurry fills the gap between the vertical mortise and tenon, making the upper and lower components stronger.

[0062] The transverse mortise and tenon include a mortise groove 14 and a transverse tenon 15. The mortise groove 14 is located at the right end of the right column 1, and the transverse tenon 15 is located at the left end of the left column 1. During the installation process, the components can be installed from top to bottom or from right to left. The end of the transverse tenon is 1 cm smaller than the end of the mortise groove. The transverse mortise and tenon can effectively increase the anchoring degree of the left and right components. After the two components are installed in place, mortar is injected into the space of the mortise and tenon in time to ensure the stability and strength of the two components.

[0063] The longitudinal mortise 16 is located at the front and rear ends of the longitudinal corrugated hole on the column. The front longitudinal mortise 16 is the installation position of the gasket and the nut after the tensioning is completed. After the tensioning is completed, it can be sealed with cement mortar of the same grade. The rear longitudinal mortise 16 is connected to the tenon of the anchor block buried in the embankment filler.

[0064] During the assembly process of components, lifting tools are needed to lift the components, such as Figure 4 As shown, a lifting hole is provided on the component. The lifting hole can utilize the vertical corrugated hole to process a lifting tool similar to the spiral corrugated pipe, and the diameter can be screwed into the vertical spiral corrugated pipe. The lifting tool can be installed diagonally before lifting, so as to achieve a balanced state during the component lifting process.

[0065] A greening pool is arranged on the bottom plate 3. The greening pool is surrounded by columns on both sides and a permeable retaining plate at the rear side. It is located in the front middle of the component and is shaped like a dustpan. The greening pool is a place where green plants grow. The greening pool is a growth space that is convex in front and sunken in the back. The sunken position is located inside the retaining wall prefabricated component. The convex part is a seesaw 10, which is a part of the ecological retaining wall. Seepage holes are arranged on the bottom plate in the greening pool to prevent the plant roots from being soaked by sufficient water and causing rot, which seriously affects the effective growth of the plants.

[0066] The permeable retaining plate is located at the rear of the component greening pool. A seepage structure 17 is provided on the permeable retaining plate. The seepage structure 17 contains countless gaps that can effectively filter the seepage water and ensure the water supply and growth of plants. The capillary root system can also take root in the road base through the permeable retaining plate, but it will not form a large root system to corrode the roadbed. The existing components only have a drainage window structure, which is connected with the roadbed filler. However, the rainy season has abundant rain, and the drainage window may cause damage to the roadbed or hollowing out. Excessive rain may cause damage to green plants. The permeable retaining plate 6 in this component can effectively ensure the stability of the roadbed filler. Even if the water volume is sufficient in the rainy season, a large runoff will not be formed at the position of the permeable retaining plate, and the road base body will not be damaged by vacuum. In the design process of the retaining wall, filtering materials are generally set to prevent the damage of the drainage hole to the road base body. The permeable retaining plate can achieve energy conservation, emission reduction and reduce project investment. In the rainy season, the permeable retaining plate can be used to drain the excess water inside the road base body and use it as a drainage hole. The road base body will not be damaged during the drainage process.

[0067] The water receiving platform is the protruding part on the rear side of this component. There is a permeable retaining board between the water receiving platform and the middle of the greening pool. In the dry season, the moisture content of the rock mass or filling materials becomes increasingly depleted, and the water or steam water leaking from the rock mass or filling materials falls onto the water receiving platform, and is filtered through the permeable retaining board to supply the green plants with what they need for growth. The water receiving platform can form a mortise and tenon structure with the filler to effectively enhance the overall stress stability of the retaining wall and the roadbed.

[0068] A watering pipe is installed vertically on the right column, which is discharged into the greening pool through a tee at the bottom plate. The pipe is pre-buried with PVC pipes, and the components are connected with quick connectors to prevent water leakage during watering.

[0069] The retaining wall component structure is divided into three categories: the first assembly, the second assembly and the third assembly. The top views of the first assembly, the second assembly and the third assembly are the same, such as Figure 5-7 As shown, the first assembly parts have the following uniform features: the first assembly part is the first layer of the retaining wall, which is located on the foundation, with the lower part remaining flat and without tenons, and vertical mortises are arranged on the upper part to facilitate the mortise and tenon connection with the upper layer components. The first assembly part I-type component is located at the left end of the first layer of the retaining wall, with a single independent column on the left side of the component and an anchor groove on the right column, which is convenient for the mortise and tenon connection with the adjacent components horizontally to increase the overall lateral force; the first assembly part II-type prefabricated component is located in the middle of the first layer of the retaining wall, with a tenon on the left column and a mortise groove on the right column, which is convenient for the mortise and tenon connection with the adjacent components horizontally to increase the overall lateral force, as shown in FIG. Figure 8 As shown, it is a schematic diagram of the horizontal connection of components. The first assembly type III prefabricated component is located at the right end of the first layer of the retaining wall. The left column is provided with a tenon to facilitate the mortise and tenon connection with the adjacent components, and there is a single independent column on the right.

[0070] Uniform features of the second assembly: The second assembly is located on the second or nth floor of the retaining wall and needs to be connected with the upper and lower adjacent components by mortise and tenon joints, such as Fig. 9 As shown, all of the components are provided with vertical mortise eyes and vertical tenons at the bottom. The second assembly type I prefabricated component is located at the left end of the second or nth layer of the retaining wall, with a single independent column on the left side of the component and a mortise groove on the right column, which is convenient for mortise and tenon connection with adjacent components in the horizontal direction to increase the overall lateral force; the second assembly type II prefabricated component is located in the middle of the second or nth layer of the retaining wall, with a horizontal tenon on the left column and a mortise groove on the right column, which is convenient for mortise and tenon connection with adjacent components in the horizontal direction to increase the overall lateral force; the first assembly type III prefabricated component is located at the right end of the second or nth layer of the retaining wall, with a horizontal tenon on the left column to facilitate mortise and tenon connection with adjacent components, and a single independent column on the right side.

[0071] like Fig.10As shown, the third assembly has the following unified features: the third assembly is located at the upper tensioning layer, and the tensioning layer is affected by the gasket and the anchor bolt. Compared with the second assembly, only the tenon of the third assembly is reduced, and the mortise and tenon will not be affected after the mortise and tenon are inserted; the third assembly type I prefabricated component is located at the left end of the upper layer of the tensioning layer, with a single independent column on the left side of the component and an anchor groove on the right column, which is convenient for mortise and tenon connection with adjacent components in the transverse direction to increase the overall transverse force; the third assembly type II prefabricated component is located in the middle of the upper part of the tensioning layer, with a tenon on the left column and a mortise groove on the right column, which is convenient for mortise and tenon connection with adjacent components in the transverse direction to increase the overall transverse force; the third assembly type III prefabricated component is located at the right end of the upper tensioning layer, with a tenon on the left column to facilitate mortise and tenon connection with adjacent components, and a single independent column on the right side, as shown Fig.11 The figure shows the schematic diagram of the vertical installation of retaining wall components.

[0072] The ecological retaining wall is assembled as a whole and consists of components and cover plates. The cover plates are divided into three different styles and are equipped with vertical and longitudinal tensioning systems. Each side column is equipped with two vertical tensioning holes. It is an integral component with a rectangular shape and a mortise and tenon structure on one or both sides of the component. Figure 12-14 As shown, the cover plate is rectangular, and the cover plate is divided into three types: left, middle and right. The thickness is the same, and only the length is different. The specification size is equal to the length and width of the prefabricated components A, B, and C. The upper part is provided with a cover plate mortise 18, the lower part is provided with a cover plate tenon 19, and the lower middle part is concave to increase the space for vegetation growth, such as Fig.15 As shown, this is a schematic diagram of cover plate placement, with the left cover plate located at the left end, the middle cover plate located in the middle, and the right cover plate located at the right end.

[0073] like Fig.16 As shown, it is the overall structure of the retaining wall. In this embodiment, the proportion of the ecological retaining wall is calculated according to the retaining wall of 10.0m long and 8.0m high. According to the above information, the prefabricated components of the assembled retaining wall are divided into two types, prefabricated components and cover plates. The customized steel formwork requires at least two types of formworks. Regardless of the progress, only two sets of steel formworks can be used for construction. Because the difference between similar components is not large, the prefabricated components only differ in the presence or absence of tenons or the size of the tenons, and the cover plates differ in size. The above solution can adopt modular design of steel formwork, modular design of tenons and mortises, bolt fixation, and the module can be moved according to different types of components. The cover plate also has the same operation method. The details of component prefabrication are shown in Table 1:

[0074] Table 1 Component prefabrication list

[0075]

[0076] The construction method is:

[0077] Step 1: Excavation of foundation pit

[0078] Before the retaining wall is constructed, the lines are measured and laid out according to the retaining wall design drawings, and then the foundation pit is excavated;

[0079] Step 2: Install the template

[0080] The template is installed according to the measurement and layout. The template uses a large steel template. The template crosses the tie rod to prevent the template from expanding.

[0081] Step 3: Pour the Concrete

[0082] The concrete is C30 concrete, which is transported by tank trucks and can be poured by pump trucks. Each layer is vibrated once until the concrete stops bubbling. Pour it to the top surface of the formwork to ensure the flatness of the top surface. At least two finishing steps are used to ensure that there are no cracks on the surface.

[0083] Step 4: Install the first layer of components

[0084] Transport the number of components required for a retaining wall, clean the dirt or residue on the surface of the concrete foundation, lay out the lines to check whether the embedded position and height of the anchor meet the design requirements. If there is a small deviation, it can be fine-tuned according to the majority obeying the minority. The components are installed with the assistance of a crane, and the vertical tensioning holes are used as temporary lifting holes. Before construction, a lifting tool is processed according to the characteristics of the vertical tensioning holes to lift the components. The first assembly type I component is installed at the left end of the first layer, multiple first assembly type II components are installed in the middle, and the first assembly type III is installed at the right end;

[0085] Step 5: Install the second layer of components

[0086] The second layer components are second assembly part type I, second assembly part type II and second assembly part type III components. The second layer components are located on the upper part of the first layer. Before installing the second layer, the flatness of the first layer installation is carefully checked to ensure that the surface of the first layer is flat and correct when installing the second layer. The second assembly part type I component is installed at the left end, multiple second assembly part type II components are installed in the middle, and the second assembly part type III component is installed at the right end. The two layers of components are connected by vertical mortises and vertical tenons.

[0087] Step 6: Install the third layer of prefabricated components

[0088] The installation method of the third layer components is the same as that of the second layer components. To ensure safe and environmentally friendly construction, vertical tensioning is performed once every three layers of components are installed until the cover plate is installed on the top of the retaining wall and tensioning and grouting are performed again;

[0089] Step 7: Tension grouting

[0090] Grouting can be carried out only after tensioning is completed, and the grade of the grouting material should be the same as the strength of the component;

[0091] Step 8: Install the upper components

[0092] After the three-layer tensioning and grouting is completed, the upper tensioning component is installed. The third assembly part type I component is installed on the left end, and multiple third assembly part type II components are installed in the middle. The third assembly part type III component is located at the right end. The installation process and method are the same as the first assembly part.

[0093] Step 9: Cover Installation

[0094] After the installation of each component is completed, the cover plate is installed on the top of the retaining wall in sequence, and the cover plate is tensioned together with the components after installation;

[0095] Step 10: Longitudinal tensioning and grouting

[0096] After the overall structure of the retaining wall is assembled, longitudinal tensioning and longitudinal grouting are finally carried out.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
