Abstract
Description
Technical Field
[0001] This utility model relates to the field of ground engineering technology, and in particular to a prefabricated assembled ground drainage ditch. Background Technology
[0002] The function of surface drainage ditches is to drain surface water and control the flow of rainwater within a certain range.
[0003] Currently, one type of ground drainage ditch in the existing technology is entirely constructed on-site, with prefabrication limited to the cover plate. Because the bottom of the ditch requires drainage and slope, the components cannot be prefabricated in a unified manner, resulting in significant limitations and poor practicality. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where the entire ditch body is built on site and the prefabrication is limited to the cover plate. Because the bottom of the ditch has drainage and slope requirements, the components cannot be prefabricated in a unified manner, which has great limitations and poor practicality. Therefore, a prefabricated assembled ground drainage ditch is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated assembled ground drainage ditch, comprising a first ditch body, with a second ditch body at both ends of the first ditch body, a first assembly block fixed at both ends of the first ditch body, an assembly groove matching the first assembly block at the end of each of the two second ditch bodies facing the first ditch body, a first fastener installed in both the first assembly block and the assembly groove, a second assembly block fixed at the end of the second ditch body away from the first ditch body, a second fastener installed at the top of the second assembly block, and a cover plate at the top of both the first ditch body and the second ditch body.
[0006] Preferably, a water collection well is installed in the first trench, and sealant is applied to the connection between the first trench and the second trench.
[0007] Preferably, the top end of the second groove is provided with an opening, and the first assembly block is installed in the opening.
[0008] Preferably, the first assembly block and the second assembly block are equal, and the first fastener and the second fastener are equal.
[0009] Preferably, the first assembly block is fixed to the second groove body by a first fastener.
[0010] Preferably, the bottom walls of both the first and second grooves are inclined arc-shaped.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] In this invention, both the first and second ditch bodies are prefabricated. The dimensions and bottom slope of the ditch bodies are designed in a standardized manner according to actual needs. The material used is polymer resin with partial reinforcement. The connection is guided by a first assembly block, a second assembly block, and an assembly groove, and secured with first and second snap-fit fasteners. By assembling fewer components to form accessories of different depths, the quality of the ditch body is improved, drainage efficiency is higher for the same cross-section, the amount of on-site wet work is reduced, labor is less, and costs are lowered. Furthermore, the device applies sealant at the connection between the first and second ditch bodies, effectively filling the gap between them, thus enhancing its practicality.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example 1, as Figure 1-3As shown, this utility model provides a prefabricated assembled ground drainage ditch, including a first ditch body 1, with a second ditch body 2 at both ends of the first ditch body 1, and a first assembly block 4 fixed at both ends of the first ditch body 1. Each of the two second ditch bodies 2 has an assembly groove 6 that matches the first assembly block 4 at the end facing the first ditch body 1. A first fastener 5 is installed in both the first assembly block 4 and the assembly groove 6. A second assembly block 8 is fixed at the end of the second ditch body 2 away from the first ditch body 1, and a second fastener 9 is installed at the top of the second assembly block 8. Both the top of the first ditch body 1 and the top of the second ditch body 2 are provided with a cover plate 10.
[0020] The overall effect of Embodiment 1 is that this device prefabricates both the first ditch 1 and the second ditch 2. The ditch dimensions and bottom slope are designed in a standardized manner according to actual needs. The material used is polymer resin with partial reinforcement. The connection is guided by the first assembly block 4, the second assembly block 8, and the assembly groove 6, and connected by the first fastener 5 and the second fastener 9. By assembling different depth accessories with fewer components, the quality of the ditch is improved, the drainage efficiency of the same cross section is higher, the amount of on-site wet work is reduced, less manpower is required, and the cost is reduced, making it more practical. The cover plate 10 can effectively prevent people from stepping into the ditch and can also block leaves and other debris from entering the first ditch 1 or the second ditch 2 to a certain extent. All subsequent ditches of this device are the same as the second ditch 2.
[0021] Example 2, as Figure 1-3 As shown, a water collection well 3 is installed inside the first trench 1. The connection between the first trench 1 and the second trench 2 is coated with sealant. An opening 7 is opened at the top of the second trench 2. The first assembly block 4 is installed in the opening 7. The first assembly block 4 is equal to the second assembly block 8. The first fastener 5 is equal to the second fastener 9. The first assembly block 4 is fixed to the second trench 2 by the first fastener 5. The bottom walls of the first trench 1 and the second trench 2 are both inclined arc-shaped.
[0022] The effect achieved by the entire embodiment 2 is that the sealant applied at the connection between the first channel 1 and the second channel 2 can effectively fill the gap between the first channel 1 and the second channel 2, making it more practical. Since the inner bottom walls of the first channel 1 and the second channel 2 are both inclined arc-shaped, the water source entering the first channel 1 and the second channel 2 can be quickly guided. Through the setting of the first fastener 5 and the second fastener 9, the first channel 1 and the second channel 2 or the second channel 2 can be fastened together with other channels.
[0023] Working Principle: When using this device, the first trench 1 and the second trench 2 are prefabricated. The trench dimensions and bottom slope are designed in a standardized manner according to actual needs. The material used is polymer resin with partial reinforcement. The components are connected using first assembly block 4, second assembly block 8, and assembly groove 6, and secured with first fastener 5 and second fastener 9. By assembling fewer components to form accessories of different depths, the device improves trench quality, increases drainage efficiency for the same cross-section, reduces on-site wet work, requires less labor, and lowers costs. Furthermore, the device applies sealant to the connection between the first trench 1 and the second trench 2, effectively filling the gaps between them, thus enhancing its practicality.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
