Description

Technical Field

[0001] The present application relates to the technical field of main catch ditches at the top of cut slopes, and specifically to a catch ditch structure for the top of a cut slope. Background Art

[0002] In road engineering, drainage at the top of a cut slope is a key link. A catch ditch, also known as a gutter, refers to a location outside the top of the cut slope of an embankment or appropriately above a hillside embankment. Its purpose is to intercept and drain the surface water flowing towards the roadbed above the roadbed, reduce the water flow burden on the side ditch, protect the cut slope and the toe of the fill slope from being scoured by water, and reduce the drainage pressure of the side ditch. Currently, the commonly used catch ditch structure is mainly made of masonry or concrete and is set on the outer side of the top of the cut slope to intercept and drain the surface water flowing towards the cut slope and protect the cut slope and the toe of the fill slope from being scoured by water.

[0003] According to a catch ditch structure for the top of a cut slope disclosed in Chinese Patent Publication No. CN208884304U, it includes a slope top, a catch ditch, and a water retaining ridge; the slope top is the slope top structure of the cut slope of the road cutting, the top surface of this slope top is provided with a downward slope towards the facing slope direction, and a catch ditch is built at a certain distance from the edge towards the back slope direction of the slope top; the catch ditch is a mortar rubble concave structure, the bottom surface of this catch ditch is a horizontal plane, and the top surface coincides with the top surface of the slope top; a sand and gravel cushion layer is laid on the bottom surface of the catch ditch; a water retaining ridge is built on the slope top towards the facing slope direction beside the catch ditch, this water retaining ridge is a concrete trapezoidal structure, and the bottom surface of the water retaining ridge is built in a stepped shape and is connected to the slope top through embedded planting bars; this structure can intercept surface runoff, prevent water flow from scouring and eroding the cut slope or the toe of the embankment slope, and cause little damage to the slope top.

[0004] However, there are still certain deficiencies in the actual use of this patent. When draining water, the rainwater on the road will flow into the interior of the catch ditch through drainage pipes or other drainage structures and then be discharged through the catch ditch. When the rain is heavy, the excess overflowing rainwater can be blocked by the water retaining ridge, but there is a lack of a structure for assisting in positioning the catch ditch. When there is a lot of rain, the catch ditch cannot quickly and effectively drain the rainwater, resulting in continuous immersion in water and being scoured by rainwater, affecting the structural stability and being not conducive to long-term stable use, thus there is a certain room for improvement in the practicality of the existing catch ditch structure for the top of a cut slope. Summary of the Utility Model

[0013] Further, the filling layer is a sand and gravel layer, the inner side of the flowing water groove is trapezoidal, and a plurality of discharge pipes are fixed at the bottom of the precast concrete ditch.

[0014] By adopting the above technical solution, it can serve as a filling structure between the inside of the catch water groove and the outside of the precast concrete ditch.

[0015] Furthermore, the number of the discharge pipes is greater than the number of the flume, and the interior of the flume is communicated with the interior of the corresponding discharge pipe.

[0016] By adopting the above technical solution, the rainwater inside the precast concrete ditch can be discharged normally.

[0017] Furthermore, the positioning rod is inserted obliquely between the interior of the precast concrete ditch, the compacted layer and the top slope body.

[0018] By adopting the above technical solution, the positioning rod can play a role in stably supporting the precast concrete ditch.

[0019] Furthermore, several of the fixing blocks are symmetrically distributed in pairs on the left and right inner side walls of the precast concrete ditch.

[0020] By adopting the above technical solution, it is convenient to fix the support rod.

[0021] Furthermore, two inclined rods are fixed at the bottom of each support rod, and the corresponding two inclined rods are symmetrically distributed left and right.

[0022] By adopting the above technical solution, the support structure composed of the corresponding two fixing blocks, one support rod and two inclined rods can play a role in positioning and supporting the left and right inner side walls and the bottom of the precast concrete ditch.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For the catch ditch structure at the top of the cutting road embankment, through the coordinated use of the water retaining block, drainage pipe, water intercepting groove and support drainage component at the top of the top slope body, the stability and actual drainage efficiency of the catch ditch can be improved, so that it can effectively drain water while improving the stability of the overall structure.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figures 1 to 3 , the present application provides a technical solution: A water intercepting ditch structure for the slope top of an excavation cutting, including the main body 1 of the slope top. A water-blocking block 2 is fixedly installed on the top of the main body 1 of the slope top. A plurality of drainage pipes 3 are fixedly installed on the top of the main body 1 of the slope top. A water-intercepting groove 4 is opened on the top of the main body 1 of the slope top. A supporting drainage assembly 500 for supporting it is installed inside the water-intercepting groove 4; through the combined use of the water-blocking block 2, the drainage pipe 3, the water-intercepting groove 4 and the supporting drainage assembly 500 on the top of the main body 1 of the slope top, the stability and actual drainage efficiency of the water intercepting ditch can be improved, so that it can effectively drain water while also enhancing the stability of the overall structure, so that its stability will not be overly reduced during continuous heavy rain washing, facilitating long-term stable use, thereby effectively improving the practicability of the water intercepting ditch structure for the slope top of an excavation cutting.

[0031] It should be noted that the main body 1 of the slope top is inclined to the left. The water-blocking block 2 is located on the left side of the water-intercepting groove 4. The drainage pipe 3 is located on the right side of the water-intercepting groove 4 and its end extends to the top of the water-intercepting groove 4, so that the water on the road can move into the water-intercepting groove 4 through the drainage pipe 3, enabling the water-intercepting groove 4 to play a normal drainage role, while the water-blocking block 2 can block the overflowing rainwater. Among them, the drainage work carried out through the drainage pipe 3 is a publicly known technology, so it will not be elaborated too much.

[0032] In this embodiment, the supporting drainage assembly 500 is a structure for playing an auxiliary supporting role and an auxiliary drainage role.

[0033] Such as Figure 1 , Figure 2 and Figure 3As shown in the figure, the support and drainage assembly 500 includes a filling layer 501 filled inside the water cutoff groove 4, a precast concrete trench 502 fixedly installed inside the filling layer 501, a water flow plate 503 fixed to the inner bottom wall of the precast concrete trench 502, a plurality of water flow grooves 504 opened at the top of the water flow plate 503 and having openings on both the front and back, a plurality of positioning rods 505 penetrating through the inside of the precast concrete trench 502, a plurality of fixing blocks 506 fixedly installed inside the precast concrete trench 502, a support rod 507 fixed between the opposite sides of two corresponding fixing blocks 506, and a plurality of inclined rods 508 fixed between the bottom of the support rod 507 and the top of the water flow plate 503.

[0034] It should be noted that the filling layer 501 is a sand and gravel layer, which can serve as a filling structure between the inside of the water cutoff groove 4 and the outside of the precast concrete trench 502, facilitating the layout and installation of the precast concrete trench 502. And during installation, it needs to be tamped to improve the stability of the installation of the precast concrete trench 502. The inner side of the water flow groove 504 is trapezoidal. Specifically, the cross-section of the water flow groove 504 is trapezoidal. A plurality of discharge pipes are fixed to the bottom of the precast concrete trench 502. The number of discharge pipes is greater than the number of water flow grooves 504. The inside of the water flow groove 504 is connected to the inside of the corresponding discharge pipe. The discharge pipe can be connected to areas such as sewers and rivers, so that the rainwater inside the precast concrete trench 502 can be discharged normally.

[0035] In addition, the positioning rod 505 is obliquely inserted between the inside of the precast concrete trench 502, the filling layer 501 and the slope top main body 1, and the positioning rods 505 are distributed on the left and right sides of the precast concrete trench 502. Among them, the positioning rod 505 is a steel bar ground pile, which can be embedded in the ground to increase the stability and load-bearing capacity of the building. Specifically, holes can be first drilled through the positioning rod 505 and then grouting material is injected into its inside, and then the positioning rod 505 is knocked in to complete the positioning installation, so that the positioning rod 505 can play a role in stably supporting the precast concrete trench 502. Thus, the precast concrete trench 502 can be connected to the slope top main body 1 through the positioning rod 505 to form an integral body. The grouting material is made of high-strength materials as aggregates, cement as a binder, supplemented by substances such as high fluidity, micro-expansion, and anti-segregation. It is added with a certain amount of water at the construction site, and can be used after being stirred evenly. It can be used for the reinforcement of road and bridge projects, machine bases, steel structures and foundation cup mouths, secondary grouting of equipment foundations, embedding steel bars, concrete structure reinforcement and transformation, sealing piles for static pressure pile projects, building reinforcement, etc.

[0036] Meanwhile, several fixing blocks 506 are symmetrically distributed in pairs on the left and right inner side walls of the precast concrete trench 502. Two inclined rods 508 are fixed to the bottom of each support rod 507, and the two corresponding inclined rods 508 are symmetrically distributed left and right, so that the support structure composed of two corresponding fixing blocks 506, one support rod 507 and two inclined rods 508 can play a role in positioning and supporting the left and right inner side walls and the bottom of the precast concrete trench 502, so as to improve the stability of the precast concrete trench 502 and prevent it from being unstable due to long-term rain erosion.

[0037] The working principle of the above embodiment is as follows:

[0038] During drainage, the rainwater on the road can be diverted through the drainage pipe 3 and flow into the precast concrete trench 502. Under the action of the water chute 504, the flow rate of the water can be increased to a certain extent, so that the rainwater can be drained more quickly, reducing the accumulation and residual time. Under the combined action of two corresponding fixing blocks 506, one support rod 507 and two corresponding inclined rods 508, the inside of the precast concrete trench 502 can be effectively supported, so that it can maintain a stable state for a long time. And under the insertion and positioning action of the positioning rod 505, it can also be connected to the inside of the slope top main body 1, so as to further position and fix the position of the precast concrete trench 502, improve the stability of the precast concrete trench 502, and enable it to drain water stably for a long time. Under the action of the water blocking block 2, when the rainwater volume is large, it can block the rainwater overflowing from the inside of the precast concrete trench 502 to a certain extent, so that even if it overflows from the inside of the precast concrete trench 502, it is not easy to continue flowing downward to the slope top main body 1. Therefore, the intercepting ditch structure can drain and intercept water stably and effectively.

[0039] Compared with the prior art, the intercepting ditch structure for the top of the cutting road embankment can improve the stability and actual drainage efficiency of the intercepting ditch through the cooperation of the water blocking block 2, the drainage pipe 3, the water intercepting groove 4 and the support and drainage assembly 500 on the top of the slope top main body 1. While effectively draining water, it can also improve the stability of the overall structure, so that its stability will not be reduced too much during continuous heavy rain erosion, facilitating long-term stable use, thus effectively improving the practicability of the intercepting ditch structure for the top of the cutting road embankment, and solving the problem that the existing intercepting ditch structure for the top of the cutting road embankment is prone to stability reduction due to heavy rain erosion during actual use and is not conducive to long-term use.
