Description

TECHNICAL FIELD

[0001] The utility model belongs to civil engineering assembly type drainage ditch technical field, concretely relates to an assembly type drainage ditch structure. BACKGROUND

[0002] The statements in this section merely provide background information related to the utility model and do not necessarily constitute prior art.

[0003] To facilitate construction, reduce pollution and influence on the surrounding, many temporary facilities are needed in the construction site, such as fences, sidewalks, drainage ditches, etc. Among them, the drainage ditch is responsible for collecting and discharging the domestic sewage, production wastewater and rainwater generated in the construction site to the designated place to prevent water accumulation from affecting the construction progress and quality. The drainage ditch in the construction site is a temporary facility serving production, which needs fast construction speed and certain quality requirements, so it is particularly suitable for assembly type construction form.

[0004] However, the drainage ditch in the construction site is still mostly brick masonry structure or simple structure made of reinforced concrete slab, which has complicated construction steps, increases the construction period of the temporary construction project in the construction site, and the installation quality cannot be guaranteed, which increases the material cost and labor cost of the site construction.

[0005] To solve the above problems, patent CN109235614A discloses an assembled recyclable temporary drainage ditch and its construction method. The drainage ditch includes an aluminum tank with a U-shaped cross section composed of a bottom plate and side plates arranged on both sides of the bottom plate, the top of each side plate of the aluminum tank is provided with a wing end outwardly flat into an ear structure, and the upper wing ends of the two side plates are distributed according to the diagonal; the bottom plate of the aluminum tank is provided with stepped slots at the front and rear ends, and the stepped slots at the front and rear ends are embedded and matched; an aluminum cover plate is arranged above the aluminum tank, and the aluminum cover plate is connected with the wing end on the aluminum tank through bolts. However, the structure is not easy to seal and butt joint at the joint, and water gushing may occur after a long time, which is not conducive to drainage.

[0006] Patent CN209082430U discloses a water conservancy corridor prefabricated drainage ditch. The outer wall ribs and inner wall grooves on the prefabricated drainage ditch unit are spliced to form an integral drainage ditch. However, the waste water generated in the construction site often carries silt, and the structure has too many protruding structures inside after splicing, which is easy to intercept sand and stones in the water and cause blockage, affecting the drainage quality after a long time of use, and frequent cleaning is needed.

[0007] Patent CN112482542A discloses a prefabricated drainage ditch structure. It achieves longitudinal connection of the drainage ditch structure by assembling connecting protrusions and mounting grooves at both ends, and seals the joints with waterproof adhesive, resulting in good drainage performance. However, this structure is relatively complex and requires high precision in the machining of the connecting protrusions and mounting grooves at both ends, thus increasing the cost. Furthermore, this structure is only suitable for relatively flat road surfaces and is difficult to apply when the construction site has varying slopes.

[0008] It is evident that the existing prefabricated drainage ditches have the following problems: the joints of the drainage ditches are not easy to seal and connect, which can easily lead to water seepage after a long period of time, which is not conducive to drainage; internal protrusions can easily cause blockages; and they cannot adapt to road surfaces with varying slopes.

[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a prefabricated drainage ditch structure, such as... Figure 1 As shown, it includes several drainage ditches 1 connected together. The drainage ditches 1 are covered with waterproof membrane 4. Multiple cover plates 2 are connected to the top of the drainage ditches 1. Adjustable supports 3 are provided at the bottom of both sides of the drainage ditches 1.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, the drainage ditch 1 includes a ditch body 11, which comprises a bottom plate and two side plates. The cross-section of the ditch body 11 is an isosceles trapezoid. The purpose of designing it as an isosceles trapezoid is that, compared to a rectangular cross-section, the isosceles trapezoidal ditch body 11 is easier to install the waterproof membrane 4 later. The function of laying the waterproof membrane 4 is to increase the waterproof capability of the ditch body 11, prevent water penetration into the ditch body 11, and improve the drainage performance of the drainage ditch.

[0035] like Figure 2 , Figure 3 As shown, both sides of the groove body 11 are fixedly connected to the top of a folded plate 12, which consists of two parallel horizontal plates 13 and a vertical plate 14. Figure 3 As shown, two small horizontal plates 13 are arranged one above the other, with the upper and lower small horizontal plates 13 connected by a vertical plate 14. In this embodiment, the vertical plate 14 is arranged obliquely between the two small horizontal plates 13, and the included angle between the vertical plate 14 and the two small horizontal plates is an obtuse angle.

[0036] like Figure 2 , Figure 3As shown, the drainage ditch 1 has an upper connecting plate 15 and a lower connecting plate 16 at both ends for connection. The upper connecting plate 15 and the lower connecting plate 16 are of the same length. When the upper connecting plate 15 and the lower connecting plate 16 of adjacent drainage ditch 1 are fastened together, no protrusion will appear on the bottom plate between the ditch bodies 11 of adjacent drainage ditch 1. In this embodiment, although no protrusion will appear between adjacent drainage ditch 1, a connection seam is inevitable. Waterproof adhesive is injected into the formed connection seam to seal the gap between the connection seams, and mortar is used to level the connection seam before laying the waterproof membrane.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, shear-resistant short columns 17 and connecting holes 18 are provided on the broken plate 12. Specifically, multiple shear-resistant short columns 17 are evenly distributed on the top surface of the lower small horizontal plate 13; multiple connecting holes 18 are evenly distributed on the bottom surface of the upper small horizontal plate 13, and the connecting holes 18 must not penetrate the upper small horizontal plate 13. Among them, the shear-resistant short columns 17 are used to connect the cover plate 2, and the connecting holes 18 are used to install the adjustable support 3.

[0038] like Figure 1 , Figure 4 As shown, the cover plate 2 has notches along the midlines of its two long sides. From a top-view perspective, the cover plate 2 is "I"-shaped. Intervals can be formed between adjacent cover plates 2, allowing rainwater to flow into the drainage ditch 1 below during rainfall. These notches also facilitate observation of whether the drainage ditch 1 is blocked, and allow personnel to easily remove any blocked cover plates 2 for cleaning. In this embodiment, the cover plate 2 has isosceles trapezoidal notches along its two long sides, forming hexagonal gaps between adjacent cover plates. It is understood that in other embodiments, gaps of other shapes, such as rectangles or squares, can be formed between the cover plates.

[0039] like Figure 1 , Figure 4 As shown, the two sides of the cover plate 2 can fit precisely between the vertical plates 14 on both sides of the drainage ditch 1. It can be understood that the angle between the two sides of the cover plate 2 and the bottom surface of the cover plate 2 is an obtuse angle, and is equal to the angle between the vertical plate 14 and the small horizontal plate.

[0040] like Figure 4As shown, the bottom surface of the cover plate 2 is provided with a circular connecting hole 21 on both sides, which is used to accommodate the shear short column 17. The circular connecting hole 21 of the cover plate 2 is sleeved on the shear short column 17 of the drainage ditch groove 1, realizing the connection of the cover plate 2 and the drainage ditch groove 1. It can be understood that the diameter of the circular connecting hole 21 is greater than the diameter of the shear short column 17, so as to facilitate installation. In this embodiment, the diameter of the circular connecting hole 21 is 2mm larger than that of the shear short column 17. It can also be understood that the spacing between the circular connecting holes 21 adjacent to the bottom surface of the cover plate 2 is equal to the spacing of the shear short columns 17 on the lower small cross plate 13 of the drainage ditch groove 1, and the spacing between the circular connecting holes 21 opposite to the bottom surface of the cover plate 2 is equal to the spacing of the shear short columns 17 on the opposite lower small cross plate 13 of the drainage ditch groove 1.

[0041] As shown in the figure, Figure 5 The adjustable support 3 includes a bolt 31, an internally threaded sleeve 32, and an expanded base screw 33. The bolt 31 includes a bolt head and a screw rod, and the expanded base screw 33 includes a screw rod and a base. Specifically, the screw rod of the bolt 31 and the screw rod of the expanded base screw 33 are connected with the internally threaded sleeve 32, the bolt 31 is located at the upper part of the internally threaded sleeve 32, and the expanded base screw 33 is located at the lower part of the internally threaded sleeve 32. Among them, the shape of the bolt head of the bolt 31 corresponds to the connecting hole 18, and the bolt head of the bolt 31 is inserted into the connecting hole 18 to connect the adjustable support 3 with the drainage ditch groove 1. In this embodiment, the bolt head of the bolt 31 adopts a hexagonal shape, and the connecting hole 18 also adopts a hexagonal shape with the same size. In other ways, the bolt head of the bolt 31 can adopt a square shape, and the connecting hole 18 also adopts a square shape with the same size.

[0042] As shown in the figure, Figure 5 The bottom of the expanded base screw 33 is a base for placing on the ground, which cooperates with the bolt 31 and the internally threaded sleeve 32 to support the drainage ditch groove 1. The adjustable support 3 can adjust the overall length, specifically by adjusting the screwing depth of the bolt 31 and the expanded base screw 33 in the internally threaded sleeve 32, the length of a single adjustable support can be adjusted.

[0043] In this embodiment, by adjusting the length of all adjustable supports 3, multiple adjacent drainage ditch grooves 1 can be leveled, the connecting joints between adjacent drainage ditch grooves 1 are relatively flat, the connected drainage ditch groove joints are not prone to protrusions and misalignment, and the drainage ditch groove 1 can be adapted to different ground surfaces; so as to avoid spending a lot of time and manpower to level the installation groove bottom of the installed drainage ditch groove 1 to the same elevation.

[0044] It can be understood that the length of the adjustable support 3 is greater than the spacing between the bottom surface of the upper small cross plate of the drainage ditch groove 1 and the bottom surface of the drainage ditch groove 1.

[0045] Specific installation process:

[0046] According to the position of the drainage ditch in the temporary building plan, an installation groove for installing the drainage ditch is dug and cleaned on the ground, and the bottom of the installation groove is flat.

[0047] The adjustable support 3 is installed integrally with the drainage ditch groove 1, so that the upper connecting plate 15 and the lower connecting plate 16 of adjacent drainage ditch grooves 1 are connected by buckling; the drainage ditch grooves 1 are leveled by adjusting each adjustable support 3, so that the connecting joints between adjacent drainage ditch grooves 1 are relatively flat.

[0048] Waterproof glue is injected between the connecting joints to seal the gaps between the connecting joints; then the connecting joints are leveled with mortar to complete the connection of the drainage ditch groove 1; then the waterproof roll 4 is laid on the groove body 11 of the drainage ditch groove.

[0049] Finally, the cover plate 2 is installed on the upper surface of the drainage ditch groove 1 through the engagement of the circular connecting hole 21 and the shear-resistant short column 17, and the overall installation of the drainage ditch is completed.

[0050] The drainage ditch structure in the embodiment is simple and convenient to install, and can realize rapid assembly; and whether the drainage ditch groove is blocked can be observed through the gap of the cover plate, and the cover plate can be directly removed to clean the deposited sand and gravel in the drainage ditch groove, so that good drainage effect is ensured; and the drainage ditch groove is leveled by the adjustable support, so that it can adapt to different terrains and has wide application range. After use, the drainage ditch groove, the cover plate and the adjustable support can still be recycled, so that the cost is reduced and the green environmental protection is improved.

[0051] Although the specific embodiments of the utility model have been described above with reference to the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
