[0003] In the construction of expressways, the technical processes of cast-in-place concrete and precast concrete components are often used to achieve roadbed and pavement drainage and rainwater collection. However, due to the large self-weight of the concrete chute itself and the complex construction environment, the construction difficulty of new roads and maintenance roads is increased. Cracks and peeling are prone to occur at the caulked joints. After years of use under natural conditions, problems such as settlement, landslide, delamination, and instability of the chute bottom are also exposed.

[0027] A prefabricated composite material chute device includes a cement mortar groove surface provided on a slope.

The cement mortar groove surface is provided with a plurality of concrete anti-slip platforms along the length direction of the prefabricated composite material chute. The prefabricated composite material chute is connected to the cement mortar groove surface and the connecting concrete anti-slip platform respectively through fixed anchor bolts.

[0028] Through the above settings, the chute can be firmly fixed on the highway slope, avoiding the displacement of the chute caused by reasons such as running water impact, and improving the service life; giving full play to the advantages of the composite material chute such as light weight and corrosion resistance.

[0029] Optionally, the upper surface of the cement mortar groove surface is flush with the upper surface of the concrete anti-slip platform, and the two are jointly used for installing the prefabricated composite material chute;

[0031] Optionally, the prefabricated composite material chute includes a water inlet, a drainage trough, a turning head, a water outlet and a water retaining plate connected in sequence from high to low. Its structure is basically the same as that of a conventional chute. The water inlet is connected to the road surface for guiding the accumulated water on the road surface into the chute.

The water outlet is used to discharge the water flow out of the slope. The water retaining plate is arranged at the end of the water outlet and connected to the position of the side ditch to ensure that the drainage can flow into the bottom of the side ditch along the water retaining plate without eroding the edge of the side ditch; it is used to prevent the flowing water from eroding the connection position between the slope and the edge of the side ditch.

[0032] Optionally, the water inlet, the drainage trough, the turning head, the water outlet and the water retaining plate are connected by the method of overlapping tiles.

The stilling basin protrudes from the upper surface of the water outlet, and a notch is arranged at the central position of the width. The notch flowing out from the central position of the stilling basin serves as a water flow channel. When the rainfall is large, a liquid level can be formed upstream of the stilling basin, and the liquid level can withstand the impact of the rapids, which is used to slow down the water flow speed.

[0042] In the above process, first construct and set the cement mortar groove surface and the concrete anti-slip platform on the slope surface of the slope, and then install the composite material chute by an assembly method, which is convenient for construction and can effectively reduce the damage degree of water to the main project, and improve the structural function and service durability.

[0043] Optionally, in S1, determine the placement angle of the water inlet at the notch position of the curbstone, pull a standard line along the slope surface of the slope, and initially place the drainage trough in combination with the standard line, and determine the position and drainage angle of the drainage trough according to the standard line.

[0044] Optionally, in S1, the size of the bottom surface of the cement mortar groove is larger than the size of the prefabricated polymer composite material chute, providing space for filling cement mortar.

[0045] Optionally, in S2, lay cement mortar according to the bottom surface shape of the prefabricated polymer composite material chute, so that the water inlet is flush with the road surface after installation, ensuring that the rainwater runoff will not erode the soil at the bottom of the trough.

[0046] Optionally, in S2, the construction method of the concrete anti-slip platform includes: excavate a horizontal platform with a set size on the slope surface of the slope, make the platform wider than the drainage trough range, and fill the wedge-shaped space formed between the platform and the slope surface with concrete until it is flush with the slope gradient, ensuring that the groove is smooth.

[0047] Optionally, in S3, install the components of the prefabricated composite material chute in a shingle overlapping manner, and fix adjacent components with bolts; including: install a drainage trough below the water inlet, and cut the length of the drainage trough according to the slope length; the installation method of the components of the turning head and the water outlet is the same as that of the components of the drainage trough, and adjacent components are fixed with bolts.

[0048] Optionally, in S4, after the installation is completed, lay anti-cracking mortar, waterproof tape and epoxy resin anti-cracking mortar in sequence at the joint between the water inlet component and the road surface, effectively reducing the phenomena of fracture and peeling at the joint and improving the service life.

[0049] Optionally, in S4, at the caulking joint between the water inlet component and the curbstone, the caulking with the curbstone is repaired using epoxy resin mortar, and the water inlet component is fixed to the side of the curbstone away from the road surface with expansion bolts to prevent it from coming off.

[0050] Optionally, it further includes step S5: the two sides of the assembled composite material chute device are backfilled and tamped with plain soil to improve the supporting ability of the slope matrix for the chute.

[0051] Embodiment 1

[0052] An assembled composite material chute device as Figure 1 shown, which includes a cement mortar groove surface 1 provided on the slope. The assembled composite material chute is installed above the cement mortar groove surface 1 and is in contact with the cement mortar groove surface 1. The cement mortar groove surface 1 is provided with a plurality of concrete anti-slip platforms 3 along the length direction of the assembled composite material chute. The assembled composite material chute is connected to the cement mortar groove surface 1 and the connecting concrete anti-slip platform 3 respectively through fixing anchor bolts 4.

[0053] The cement mortar groove surface 1 is made of cement mortar with a thickness of 5 cm; its upper surface is flush with the concrete anti-slip platform 3, and both are jointly used for installing the assembled composite material chute; the bottom platform size of the concrete anti-slip platform 3 is 50 cm * 35 cm, and the size in the width direction of the chute is larger than the size in the length direction of the chute.

[0054] As Figure 2 shown, the assembled composite material chute includes a water inlet 21, a drainage trough 22, a turning head 23, a water outlet 24, and a water retaining plate 25 that are connected in sequence from high to low. Its structure is basically the same as that of a conventional chute. As Figure 3 shown, the water inlet 21 is connected to the road surface and is used to introduce the accumulated water on the road surface into the chute. As Figure 4 shown, the drainage trough 22 serves as a drainage channel. As Figure 5 shown, the turning head 23 is used to adjust the angle of the drainage trough according to the slope angle. As Figure 6 shown, the water outlet 24 is used to discharge the water flow out of the slope. As Figure 8 shown, the water retaining plate 25 is arranged at the end of the water outlet, so that the collected rainwater flows along the water retaining plate 25 into the bottom of the side ditch 6 and does not erode the edge of the side ditch 6.

[0055] As Figures 3 to 8As shown, the water inlet 21, drainage trough 22, elbow 23, water outlet 24 and baffle 25 are connected by the method of overlapping tiles. Bolt holes 5 are respectively arranged at the overlapping positions of adjacent two components. Bolts are used to pass through the overlapping bolt holes 5 at the overlapping part for fixation. The installation method of covering the lower component partially by the upper component improves the waterproof ability of the chute, avoiding the infiltration of flowing water below; the method of overlapping tiles is conducive to prefabricated standardized product components, which are light in weight, assemblable, simplify the construction method, improve the construction efficiency, and effectively reduce the labor cost.

[0056] As Figure 7 shown, a stilling basin 241 is arranged at the water outlet 24. The stilling basin 241 protrudes from the upper surface of the water outlet 24. During the period of concentrated rainfall, the drainage flow velocity is too large. The water flow outlet of the stilling basin is located at the middle position of the width of the water outlet, which can reduce the drainage speed of the water outlet, reduce the situation of drainage flushing out the side ditch 6, and reduce the erosion of the side ditch 6.

[0057] The assembled composite material chute is made of SMC polymer composite material, which has the characteristics of corrosion resistance, high compressive strength, aging resistance, light weight, etc., and can effectively improve the durability.

[0058] The fixed anchor bolts 4 are installed on both sides of the assembled composite material chute. Fixed anchor bolts of multiple sizes such as 1m, 80cm, and 50cm can be used. According to the soil condition of the slope surface, as Figures 3 to 7 shown, they are fixedly combined in the bolt holes 41 along the sides of each component and penetrate into the underlying soil or the concrete anti-slip platform 3 to solve the floating phenomenon caused by the light weight.

[0059] The fixed anchor bolts 4 include multiple lengths, such as multiple lengths of 1m, 80cm, 50cm, etc. As Figure 1 shown, the fixed anchor bolt 4 with a length of 1m is designed at the position of the water inlet 21, the fixed anchor bolt 4 with a length of 80cm is arranged at the position of the slope drainage trough 22, and the fixed anchor bolt 4 with a length of 50cm is arranged at the position of the water outlet 24 at the foot of the slope.

[0060] The construction method of the assembled composite material chute device in this embodiment includes the following steps:

[0061] S1. Determine the placement angle of the water inlet 21 at the notch position of the curbstone, pull a standard line along the slope surface of the slope, and preliminarily place the drainage trough 22 in combination with the standard line. Determine the position and drainage angle of the drainage trough 22 according to the standard line; according to the installation position of the assembled composite material chute, excavate a trench on the slope surface of the slope. The size of the trench bottom is larger than the size of the assembled polymer composite material chute, and the loose soil in the trench is tamped to form a trench surface.

[0062] S2. Lay cement mortar at the set position at the bottom of the groove surface to form a cement mortar groove surface 1, and make the water inlet 21 flush with the road surface after installation to ensure that rainwater runoff will not erode the soil at the bottom of the groove. Excavate a 50 cm * 35 cm horizontal platform on the slope surface at the set position at the bottom of the cement mortar groove surface 1, making the platform wider than the drainage trough range. Fill the wedge-shaped space formed between the platform and the slope surface with concrete until it is flush with the slope surface to ensure the smoothness of the groove, and pre-embed fixed anchor bolts 4 in the cement mortar groove surface 1 and the concrete anti-slip platform 3 respectively.

[0063] S3. Install an assembled polymer composite material rapid flow channel on the cement mortar groove surface 1, install the components of the assembled composite material rapid flow channel in the form of overlapping tiles, and fix adjacent components with bolts. It includes: install a drainage trough 22 below the water inlet 21, and cut the length of the drainage trough 22 according to the slope length. The installation method of the components of the turning head 23 and the water outlet 24 is the same as that of the components of the drainage trough 22, and adjacent components are fixed with bolts.

[0064] S4. Install the assembled composite material rapid flow channel on the fixed anchor bolt 4. After installation, lay crack-resistant mortar, waterproof tape and epoxy resin crack-resistant mortar in sequence at the joint between the water inlet 21 and the road surface. Repair the joint with the curbstone at the joint between the water inlet 21 and the curbstone with epoxy resin mortar, and fix the water inlet component on the side of the curbstone away from the road surface with expansion bolts to complete the construction.

[0065] Step S5. Backfill and tamp the two sides of the assembled composite material rapid flow channel device with plain soil to improve the supporting capacity of the slope matrix for the rapid flow channel.

[0066] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
