Description

Technical Field

[0001] This invention patent relates to the technical field of greening planting. Specifically, it relates to the construction method of greening planting in the bypass wetland of the river course. Background Art

[0002] Urban greening construction is an important environmental ecological construction project, which can play an important role in protecting the urban water resources and soil quality. Among them, the greening planting in the bypass wetland of the river course is an important part of urban greening and ecological restoration.

[0003] With the improvement of construction technology, the requirements for wetland greening planting have also increased. Especially in terms of soil and water conservation, construction site stability and construction efficiency, high-quality requirements need to be met.

[0004] In the existing traditional construction methods, inspection wells and trenches are not effectively formed in the soil of the construction site, and there are no properly arranged drain pipes in the trenches, which leads to low construction efficiency of the drainage system and cannot effectively cope with the problem of excessive water during the construction process. Since one end of the drain pipe is not closed and there is no drain outlet, the water body cannot be discharged smoothly, resulting in serious waterlogging in the construction site, affecting the continuity of construction and construction efficiency.

[0005] In addition, the existing drain pipes usually lack the filter cotton layer wrapped around the outer periphery, resulting in the water body accumulated in the soil not being able to penetrate into the drain pipe quickly. As a result, the construction site often faces water disaster problems, the construction efficiency is significantly affected, the construction period is delayed, and resources are wasted seriously. Summary of the Invention

[0006] The purpose of the present invention is to provide a construction method for greening planting in the bypass wetland of the river course, aiming to solve the problem of low overall construction efficiency in the existing technology.

[0007] The present invention is implemented as follows, including the following construction steps:

[0008] 1), Demarcate the construction site in the bypass wetland of the river course, and measure and set out the construction site.

[0009] 2), Construct inspection wells and a plurality of trenches in the soil of the construction site, arrange drain pipes in the trenches, one end of the drain pipe is arranged in a closed manner, the other end of the drain pipe has a drain outlet, and the drain outlet communicates with the inspection well; after arranging the drain pipes, backfill and process the trenches.

[0010] A cotton wool layer for water filtration is wrapped around the outer periphery of the water seepage pipe. The bottom of the water seepage pipe is arranged in a closed manner, and water seepage holes are respectively provided at the top and both sides of the water seepage pipe; (When there is too much water in the soil, such as on rainy days, etc., the water can penetrate through the cotton wool layer and the water seepage holes, seep into the water seepage pipe, and be discharged into the inspection well for standby, or be discharged into the municipal pipeline through the inspection well).

[0011] 3), Lay crushed stone materials on the construction site to form a crushed stone layer;

[0012] 4), Lay a geotextile on the crushed stone layer;

[0013] 5), Spread planting soil on the geotextile to form a planting soil layer;

[0014] 6), Lay a plurality of turf blocks on the planting soil layer. There are inter-block gaps between adjacent turf blocks. In the inter-block gaps, the turf blocks have block side edges facing the inter-block gaps; Fine soil bodies are filled in the inter-block gaps, and by squeezing the fine soil bodies, the adjacent block side edges are arranged flush.

[0015] Further, in the construction step 1), after the construction site is demarcated, the measurement control points marked on the construction drawings are re-measured, and a measurement control network is established to perform point-by-point measurement control during the construction process.

[0016] Further, in the construction step 3), the construction site is divided into multiple block-shaped areas in a block-by-block manner, and the crushed stone materials are sequentially laid in each block-shaped area.

[0017] Further, in the construction step 3), the outer periphery of the block-shaped area has a regional boundary. During the process of laying the crushed stone materials in the block-shaped area, the crushed stone materials in the block-shaped area extend beyond the regional boundary to form an extension part, and the extension parts of the crushed stone materials in adjacent block-shaped areas are arranged in an overlapping manner, so that the crushed stone materials in adjacent block-shaped areas are combined into one body.

[0018] Further, in the construction step 3), during the process of laying the crushed stone materials, a roller is used to perform layered vibration compaction on the crushed stone materials, so that the compactness of the formed crushed stone layer reaches the set requirements.

[0019] Further, in the construction step 3), during the process of laying the crushed stone materials, clay materials are mixed into the crushed stone materials, and during the process of using the roller to perform layered vibration compaction on the crushed stone materials, clay materials are scattered into the crushed stone materials.

[0020] Further, in the construction step 4), after laying the geotextile on the gravel layer, fixing nails are used to penetrate the geotextile to relatively fix the geotextile and the gravel layer; the lower part of the fixing nail penetrates into the gravel layer to form an insertion section, and the upper part of the fixing nail is exposed on the geotextile to form an exposed section;

[0021] An arc-shaped spherical cover is provided on the exposed section. The spherical cover has a spherical cavity with an opening at the bottom. The exposed section extends into the spherical cavity and is fixedly connected to the spherical cover as a whole; an elastic block is filled in the spherical cavity, and the exposed section passes through the elastic block; after the insertion section is inserted into the gravel layer, the elastic block presses against the geotextile and is in a compressed deformation state.

[0022] Further, there is an annular interval between the outer periphery of the elastic block and the inner side wall of the spherical cavity. The annular interval is arranged in a circumferential direction around the spherical cover; the top of the elastic block presses against the top of the spherical cavity, and the bottom of the elastic block extends out of the bottom opening of the spherical cavity;

[0023] In the construction step 4), after the insertion section is inserted into the gravel layer, the bottom of the elastic block presses against the geotextile. After the elastic block is pressed and deformed, the pressing force of the elastic block is compressed into the spherical cavity, the bottom of the spherical cover abuts against the geotextile, and the outer periphery of the elastic block expands outwards and abuts against the inner side wall of the spherical cavity.

[0024] Further, a plurality of sheet-shaped elastic strips extend outwards from the outer periphery of the spherical cover. The plurality of elastic strips are arranged at intervals in the circumferential direction around the spherical cover. The inner ends of the elastic strips are butted against the outer periphery of the spherical cover, and the outer ends of the elastic strips extend away from the spherical cover. The elastic strips protrude downwards in an arc shape;

[0025] In the construction step 4), when the insertion section is inserted into the gravel layer and the elastic block is pressed and compressed, the geotextile forms a downwardly concave disc-shaped groove around the outer periphery of the fixing nail. The plurality of elastic strips abut against the bottom of the groove from top to bottom, and the elastic strips are pressed and deformed upwards so that the elastic strips generate a downward pressing restoring force.

[0026] Further, in the construction step 6), after laying a plurality of turf blocks on the planting soil layer, a roller is used to roll and press the plurality of turf blocks unidirectionally along a set direction.

[0027] Compared with the prior art, the steps of the river bypass wetland greening planting construction method provided by the present invention have the following advantages:

[0028] 1) First, demarcate the construction site in the river bypass wetland and conduct precise survey and layout. This crucial step ensures the accuracy and efficiency of subsequent work, laying a solid foundation for the entire construction process. By reducing rework and delays caused by inaccurate surveying, it significantly improves the construction continuity and overall construction efficiency.

[0029] 2) Construct an efficient drainage system by forming inspection wells and trenches in the soil of the construction site and arranging drain pipes with one end closed and the other end as a drainage outlet in the trenches. The design of the filter cotton layer wrapped around the outer periphery of the drain pipe and the water seepage holes at the top and on both sides enables excessive water to quickly penetrate into the drain pipe and be discharged to the inspection well, effectively avoiding waterlogging problems at the construction site, reducing construction interruptions caused by water accumulation, and improving construction continuity and overall construction efficiency.

[0030] 3) Finally, it also includes the steps of quickly laying crushed stone on the construction site to form a crushed stone layer, and laying geotextile and planting soil layer on the crushed stone layer, which not only speeds up the construction progress but also provides a solid foundation for subsequent greening planting and enhances the stability of the construction site;

[0031] The efficient laying and fixing of turf blocks further accelerates the greening process. By filling the fine soil in the gaps between the blocks, it enhances the connection and stability between the turf blocks, improves the durability of the greening effect. In this way, it greatly shortens the construction time, improves the overall construction efficiency, and avoids the problem of long construction time for hierarchical structure laying.

[0042] Refer to Figure 1-4 As shown, it is a preferred embodiment provided by the present invention.

[0043] The construction method for greening planting in a bypass wetland of a river channel includes the following construction steps:

[0044] 1), demarcate the construction site in the bypass wetland of the river channel and conduct surveying and setting out for the construction site;

[0045] 2), construct an inspection well 102 and a plurality of trenches in the soil body 100 of the construction site, arrange a water seepage pipe 101 in the trenches, one end of the water seepage pipe 101 is arranged in a closed manner, the other end of the water seepage pipe 101 has a drainage port, and the drainage port communicates with the inspection well 102; after arranging the water seepage pipe 101, backfill the trenches.

[0046] The outer periphery of the water seepage pipe 101 is wrapped with a cotton wool layer 103 for water filtration. The bottom of the water seepage pipe 101 is arranged in a closed manner, and water seepage holes 104 are respectively provided at the top and both sides of the water seepage pipe 101; (When there is too much water in the soil mass 100, such as on a rainy day, etc., the water can penetrate through the cotton wool layer 103 and the water seepage holes 104, penetrate into the water seepage pipe 101, and be discharged into the inspection well 102 for standby, or be discharged into the municipal pipeline through the inspection well 102)

[0047] 3), Lay crushed stone materials on the construction site to form a crushed stone layer 200;

[0048] 4), Lay a geotextile 201 on the crushed stone layer 200;

[0049] 5), Spread planting soil on the geotextile 201 to form a planting soil layer 300;

[0050] 6), Lay a plurality of turf blocks 301 on the planting soil layer 300. There are inter-block gaps 303 between adjacent turf blocks 301. In the inter-block gaps 303, the turf blocks 301 have block side edges facing the inter-block gaps 303; Fine soil mass 302100 is filled in the inter-block gaps 303, and by squeezing the fine soil mass 302100, the adjacent block side edges are arranged flush.

[0051] The steps of the above-provided construction method for greening planting in the bypass wetland of the river have the following advantages:

[0052] 1), First, demarcate the construction site in the bypass wetland of the river and conduct precise measurement and setting out. This key step ensures the accuracy and efficiency of subsequent work, lays a solid foundation for the entire construction process, and significantly improves the continuity and overall construction efficiency of the construction by reducing rework and delays caused by inaccurate measurement.

[0053] 2), By forming an inspection well 102 and a trench in the soil mass 100 of the construction site and arranging a water seepage pipe 101 with one end closed and the other end having a drainage outlet in the trench, an efficient drainage system is constructed. The design of the water filtration cotton wool layer 103 wrapped around the outer periphery of the water seepage pipe 101 and the water seepage holes 104 at the top and both sides enables excessive water to quickly penetrate into the water seepage pipe 101 and be discharged into the inspection well 102, effectively avoiding water disasters at the construction site, reducing construction interruptions caused by waterlogging, and improving the continuity and overall construction efficiency of the construction.

[0054] 3), Finally, it also includes the steps of quickly laying crushed stone materials on the construction site to form a crushed stone layer 200, and laying a geotextile 201 and a planting soil layer 300 on the crushed stone layer 200, which not only speeds up the construction progress, but also provides a solid foundation for subsequent greening planting and enhances the stability of the construction site;

[0055] The efficient laying and fixing of grass blocks 301 further accelerates the greening process. By filling the gaps 303 between blocks with fine soil 302100, the connection and stability between the grass blocks 301 are enhanced, and the durability of the greening effect is improved. This greatly shortens the construction time, improves the overall construction efficiency, and avoids the problem of time-consuming laying of hierarchical structures.

[0056] In this embodiment, in construction step 1), after the construction site is delineated, the measurement control points marked on the construction drawings are re-measured, and a measurement control network is established to perform point-by-point measurement control during the construction process. In this way, the accuracy and consistency of the construction are ensured, rework due to measurement errors is avoided, and the overall construction efficiency is improved.

[0057] In this embodiment, in construction step 3), the construction site is divided into multiple block areas, and crushed stone is laid in each block area in sequence. This method allows construction to be carried out in parallel, reduces waiting time, and each area can operate independently, which improves the flexibility and efficiency of construction.

[0058] In this embodiment, in construction step 3), the periphery of the block area has a region boundary. During the process of laying crushed stone in the block area, the crushed stone in the block area extends out of the region boundary to form an extension. The extensions of the crushed stone in adjacent block areas are overlapped to combine the crushed stone in adjacent block areas into one. In this way, the independent block areas are connected into a whole, thereby enhancing the continuity and stability of the entire crushed stone layer 200.

[0059] The overlapping of the extended parts not only improves the flexibility of construction, but also reduces the gaps caused by discontinuity between areas, which may cause soil erosion or uneven settlement, ensuring the long-term performance of the site after construction.

[0060] In this embodiment, in construction step 3), during the process of laying crushed stone, a road roller is used to perform layered vibration rolling on the crushed stone so that the compaction degree of the formed crushed stone layer 200 reaches the set requirements. The layered rolling ensures the uniformity and stability of the crushed stone layer 200, avoids subsequent problems caused by uneven compaction, and improves the construction quality of the crushed stone layer 200.

[0061] In this embodiment, in construction step 3), during the process of laying crushed stone, clay is mixed into the crushed stone, and during the process of layered vibration rolling of the crushed stone by a road roller, clay is spread into the crushed stone. In this way, the mixed compaction method improves the bonding strength and durability of the crushed stone layer 200, reduces the subsequent maintenance cost, and speeds up the construction progress.

[0062] In this embodiment, in construction step 4), after laying the geotextile 201 on the gravel layer 200, the fixing nails 202 are used to pass through the geotextile 201 to relatively fix the geotextile 201 and the gravel layer 200; the lower part of the fixing nail 202 penetrates into the gravel layer 200 to form an insertion section 203, and the upper part of the fixing nail 202 is exposed on the geotextile 201 to form an exposed section 204;

[0063] An arc-shaped spherical cover 205 is provided on the exposed section 204. The spherical cover 205 has a spherical cavity 206 with an open bottom. The exposed section 204 extends into the spherical cavity 206 and is fixedly connected to the spherical cover 205 as a whole; an elastic block 207 is filled in the spherical cavity 206, and the exposed section 204 passes through the elastic block 207; after the insertion section 203 is inserted into the gravel layer 200, the elastic block 207 presses against the geotextile 201 and is in a compressed deformation state.

[0064] Through the above structure, not only the adhesion between the geotextile 201 and the gravel layer 200 is enhanced, but also the influence on the geotextile 201 caused by the uneven settlement of the base layer is reduced through the buffering effect of the elastic block 207, thereby improving the stability and durability of the overall structure.

[0065] In addition, the spherical cover 205 also helps to protect the exposed section 204 of the fixing nail 202, prevent the geotextile 201 from being damaged by external forces, ensure the stability of the upper structure, and improve the reliability and efficiency of construction.

[0066] In this embodiment, there is an annular interval between the outer periphery of the elastic block 207 and the inner side wall of the spherical cavity 206. The annular interval is arranged circumferentially around the spherical cover 205; the top of the elastic block 207 presses against the top of the spherical cavity 206, and the bottom of the elastic block 207 extends out of the bottom opening of the spherical cavity 206. In this way, when the elastic block 207 is compressed, it can uniformly expand towards the inner side wall of the spherical cavity 206;

[0067] In construction step 4), after the insertion section 203 is inserted into the gravel layer 200, the bottom of the elastic block 207 presses against the geotextile 201. After the elastic block 207 is pressed and compressed, the pressing of the elastic block 207 is compressed into the spherical cavity 206, the bottom of the spherical cover 205 abuts against the geotextile 201, and the outer periphery of the elastic block 207 expands outwards and abuts against the inner side wall of the spherical cavity 206.

[0068] In this way, not only the tight connection between the geotextile 201 and the gravel layer 200 is ensured, but also additional stability is provided to prevent the geotextile 201 from shifting during construction or use. This compression and expansion behavior of the elastic block 207 enhances the adaptability of the entire structure to uneven settlement and improves the reliability and long-term performance of construction.

[0069] In this embodiment, a plurality of sheet-like elastic strips 208 extend outward from the outer periphery of the spherical cover 205. The plurality of elastic strips 208 are arranged at intervals around the circumferential direction of the spherical cover 205. The inner ends of the elastic strips 208 are butted against the outer periphery of the spherical cover 205, and the outer ends of the elastic strips 208 extend away from the spherical cover 205. The elastic strips 208 protrude downward in an arc shape.

[0070] In construction step 4), when the insertion section 203 is inserted into the gravel layer 200 and the elastic block 207 is pressed and compressed, the geotextile 201 forms a downwardly concave disc-shaped groove. The groove surrounds the outer periphery of the fixing nail 202. The plurality of elastic strips 208 abut against the bottom of the groove from top to bottom, and the elastic strips 208 are pressed and deformed upward, so that the elastic strips 208 generate a downward pressing restoring force.

[0071] In this way, the mechanical biting effect between the geotextile 201 and the gravel layer 200 is significantly enhanced, providing a more stable connection, effectively preventing the displacement of the geotextile 201, and at the same time absorbing and dispersing the interlayer stress, enhancing the overall stability of the structure.

[0072] In this embodiment, in construction step 6), after laying a plurality of turf blocks 301 on the planting soil layer 300, a roller is used to roll one-way along a set direction on the plurality of turf blocks 301. By the one-way rolling method, the tight combination of the turf blocks 301 and the soil is ensured, the uniformity and stability of the greening planting are improved, the displacement of the turf blocks 301 caused by uneven rolling is reduced, and the construction quality and efficiency are improved.

[0073] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
