Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a combined slope drainage system. Background Art

[0002] The top slope of the buttress retaining wall is an artificial backfill slope, and its strength must meet the requirements of slope stability, so that the slope can maintain better stability under the action of rainfall and other forms of weathering. As we all know, the main forms of slope damage are scouring and collapse. For example, under the scouring action of a large amount of precipitation, many small gullies are formed along the slope runoff direction. Another example is that repeated expansion forms many irregular cracks that destroy the rock and soil structure, and the shear strength of the slope is attenuated due to the increase of water content and the influence of external factors such as dry-wet cycles, making slope protection difficult.

[0003] Traditional slope excavation or filling and other construction activities have the following problems: the original landform and vegetation are destroyed, the soil's resistance to erosion is reduced, erosion is aggravated, the surface structure of the exposed surface produced by construction is loose, the vegetation coverage rate is low, and the survival rate of grass is low. In particular, the soil of cement soil slopes makes it impossible for vegetation to grow, and the sown grass seeds are easily affected by factors such as wind and rain and lost in large quantities, which can easily cause damage to the exposed slopes and soil erosion; the slope surface is not reinforced to strengthen and stabilize, and the drainage effect is poor. After the rainy season, the slope surface is easily damaged by heavy rain and runoff, so the protection reliability is low.

[0004] For example, the Chinese patent number CN220132889U discloses a slope backfill soil drainage system and a slope backfill structure, which discloses a technical solution for slope backfill and drainage. However, this technical solution still cannot effectively solve the problem of slope construction destroying the original landform and vegetation, and there are no intensive and efficient reinforcement measures, which easily leads to the problem of newly sown grass seeds being easily lost.

[0033] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0034] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a combined slope drainage system provided by the utility model.

[0035] A combined slope drainage system is used for reinforcing and draining a slope, wherein a buttress retaining wall is provided at the foot of the slope, and the combined slope drainage system comprises:

[0036] A longitudinal drainage component 1, the longitudinal drainage component 1 comprising a plurality of longitudinal drainage ditches arranged side by side, the longitudinal drainage ditches being arranged along the longitudinal direction of the slope and used for draining water downwards;

[0037] A transverse interception assembly 2, the transverse interception assembly 2 comprising a plurality of transverse interception ditches arranged side by side, the transverse interception ditches being arranged transversely along the slope and being connected to a plurality of longitudinal drainage ditches respectively, the transverse interception ditches being used to intercept the water flow on the slope and merge it into the longitudinal drainage assembly 1;

[0038] A reinforcement component, the reinforcement component includes a hanging mesh 4 laid on the surface of the slope, a foreign soil spraying base material laid on the surface of the slope and used to cover the hanging mesh 4, and a reinforcement member used to penetrate the foreign soil spraying base material and the hanging mesh 4 and be inserted into the slope, the foreign soil spraying base material is used to mix plant seeds.

[0039] It can be understood that by adopting the longitudinal drainage ditch assembly 1 and the transverse drainage ditch assembly 2 arranged in a crisscross pattern, efficient drainage is achieved, thereby improving the drainage effect of the slope. The arranged transverse intercepting ditches collect the water flow to the longitudinal drainage ditch, and the longitudinal drainage ditch is used to centrally drain the water to the foot of the slope. The longitudinal drainage ditch is arranged at intervals, and the water flow of each part of the slope can be centrally and quickly drained. It should be noted that the longitudinal direction refers to the slope direction from the top of the slope to the bottom of the slope, and the transverse direction refers to the direction extending on the slope surface along the horizontal direction.

[0040] In addition, the slope is reinforced by using reinforcement components, and the foreign soil spraying substrate of the reinforcement component adopts the original soil to avoid damaging the original landform of the construction site; the foreign soil spraying substrate includes plant seeds for spraying, wherein the plant seeds can adopt varieties that meet the local climate to avoid damaging the original vegetation, and the foreign soil spraying substrate is reinforced by the hanging mesh 4 in combination with the reinforcement piece to reduce the loss of newly sown plant seeds; when the vegetation grows, the surface layer of the hanging mesh 4 and the foreign soil spraying substrate under the hanging mesh have been entangled, connected, crossed and entangled by the roots of the vegetation, and at the same time, the slope soil is connected up and down and left and right, realizing a reinforced fixing system that integrates points into a surface and integrates the entire slope, and has better stability.

[0041] Preferably, please refer to Figure 5 and Figure 7 As shown, a plurality of protrusions are arranged in the longitudinal direction of the slope in the longitudinal drainage ditch, and the cross section of the protrusion is triangular. Specifically, the protrusion includes a first water guide surface 9 and a second water guide surface 10, the first end of the first water guide surface 9 is connected to the slope, the second end of the first water guide surface 9 is connected to the second water guide surface 10, the first water guide surface 9 is used to guide the water flow to the second water guide surface 10, and the second water guide surface 10 is used to guide the water flow to the next protrusion, and the inclination angle of the first water guide surface 9 relative to the slope is smaller than the inclination angle of the second water guide surface 10 relative to the slope.

[0042] It can be understood that the protrusions arranged in the longitudinal drainage ditch can reduce the pressure on the longitudinal drainage ditch, can effectively reduce the impact force of waves when the water flow is large, has the effect of improving the stability of the longitudinal drainage ditch and extending the service life of the longitudinal drainage ditch. At the same time, the inclination angle of the first inclined surface 9 of the protrusion is relatively gentle, and it can also distribute impurities in the water flow, reducing the problem of the longitudinal drainage ditch being blocked by a large amount of impurities at the same time.

[0043] Preferably, please refer to Figure 1 and Figure 2 As shown, the plurality of transverse intercepting ditches are respectively arranged at the top of the slope, the top of the buttress retaining wall and various graded steps of the slope.

[0044] It is understandable that in order to reduce the infiltration of surface water into the slope body, the drainage project of high and steep slopes should be handled by means of graded interception and combined vertical and horizontal drainage. The surface water outside the top of the slope of the utility model is discharged from the horizontal interception ditch at the top of the slope; each step of the graded slope is provided with a horizontal interception ditch to drain the water to the vertical drainage ditch and then to the foot of the slope; the top of the buttress retaining wall, that is, the foot of the slope, is also provided with a horizontal interception ditch to discharge the accumulated water on the top of the buttress retaining wall, thereby achieving an all-round and three-dimensional slope efficient drainage effect.

[0045] Preferably, please refer to Figure 3 and Figure 6 As shown, the transverse intercepting ditch includes an intercepting groove 7 and a mounting groove 8 arranged next to the intercepting groove 7. The intercepting groove 7 is opened upward and is used to receive drainage from the slope, and the mounting groove 8 is opened downward and is used to cooperate with a preset boss on the slope.

[0046] It can be understood that the water cut-off groove 7 plays a role in lateral drainage, and the installation groove 8 can strengthen the positioning of the lateral water cut-off assembly 2 as a whole by cooperating with the boss of the slope, thereby improving the installation stability of the lateral water cut-off assembly 2.

[0047] It should be noted that the side wall of the intercepting groove 7 connected to the inclined surface of the slope is a slope structure to more smoothly receive the water flow. In addition, when the installation groove 8 is provided on the side of the intercepting groove 7 close to the slope foot, the outer wall surface of the installation groove 8 close to the slope foot is a slope structure to more smoothly engage with the slope of the slope.

[0048] Preferably, please refer to Figure 2 , 4 As shown, the soil-spraying substrate comprises a base layer and a surface layer covering the base layer, and the surface layer is used for incorporating plant seeds.

[0049] It is understandable that the use of imported soil can effectively reduce the changes to the original soil and landforms of the construction site. At the same time, plant seeds can use the original varieties of the construction site or varieties that are suitable for the local climate to reduce the impact on the original ecology.

[0050] Preferably, please refer to Figure 4 As shown, the base layer is used to cover the hanging mesh 4.

[0051] It can be understood that the hanging mesh 4 plays the role of connecting the skeleton inside the base layer. When the plants grow, the roots of the plants will intertwine the soil spraying substrate with the hanging mesh 4 and the slope soil layer to form a high-strength integrated structure.

[0052] It should be noted that the thickness of the base layer is thicker than that of the surface layer, and the base layer plays the role of a foundation, and can provide better stable support in conjunction with the hanging mesh 4. After the surface layer is sprayed, a non-woven fabric is covered on the surface layer to provide protection.

[0053] Preferably, please refer to Figure 4 As shown, the reinforcement member includes anchors 5, which are arranged on the slope and matched with anchor holes preset in the slope, and the anchors 5 are used to anchor and reinforce the hanging mesh 4 and the soil spraying substrate. Specifically, the angle of the anchors 5 relative to the side of the slope toward the slope foot is 95° to 105°.

[0054] It is understandable that the anchor 5 can simultaneously strengthen and fix the soil spraying substrate and the hanging mesh 4, thereby improving the stability of both. The angle setting of the anchor is not completely perpendicular to the slope surface, but can be understood as being set more toward the top of the slope, which is conducive to improving the impact resistance and anti-dumping ability of the anchor 5.

[0055] It should be noted that an anchor claw or a diagonal brace may be provided on the top of the anchor to strengthen the fixation of the anchor, so that the anchor has a stronger impact resistance.

[0056] Preferably, please refer to Figure 1 and Figure 2 As shown, the combined slope drainage system also includes a drainage pipe 6 arranged in the buttress retaining wall, and the drainage pipe 6 is used to drain the seepage water inside the slope and the buttress retaining wall.

[0057] It can be understood that the drainage pipe 6 in the buttress retaining wall can discharge the seepage water in time, which can reduce the impact and extrusion of the buttress retaining wall, and is conducive to improving the stability of the buttress retaining wall.

[0058] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0059] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
