Description

Technical Field

[0001] This utility model relates to the field of drainage structure technology, specifically a drainage ditch structure for steep slope construction. Background Technology

[0002] Drainage ditches are typically installed at the top of slopes to prevent surface water erosion and reduce the risk of slope instability. In civil engineering fields such as water conservancy, landscaping, roads, and buildings, drainage ditches are widely used and come in various forms. A common practice is to excavate a trench and then pour reinforced concrete to form the drainage ditch structure, which is stable and durable. However, for some temporary projects (such as the entrance of diversion tunnels), where the slopes are steep and the excavated slopes have a short service life, using traditional reinforced concrete drainage ditches presents significant challenges in terms of excavation difficulty and cost. Simplifying the drainage ditch structure and optimizing the construction process has become a major challenge for design engineers.

[0003] Therefore, it is of great significance to develop a drainage ditch structure for steep slope construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a drainage ditch structure for steep slope construction. This structure should have the advantages of low cost, simple structure and convenient construction.

[0005] The technical solution of this utility model is: A drainage ditch structure for steep slope construction includes a steel plate fixed to the steep slope by reinforcing bars and a concrete foundation filled between the steel plate and the steep slope; the inner wall of the steel plate, the top surface of the concrete foundation and the slope surface together form a drainage ditch for diverting water flow on the slope.

[0006] The upper part of the reinforcing bar is welded and fixed to the outer wall of the steel plate, and the lower part of the reinforcing bar is inserted into the soil layer of the steep slope.

[0007] The steel plate has a wooden template for sealing the gap between its lower edge and the steep slope.

[0008] The outer surfaces of the steel plate and reinforcing bars are all coated with anti-corrosion coating.

[0009] The beneficial effects of this utility model are: This structure forms a drainage ditch by enclosing a steel plate, concrete foundation, and slope, which eliminates the need for trenching on steep slopes, reduces disturbance to the soil, and lowers the risk of instability and construction costs. At the same time, the steel plate also serves as the formwork for the concrete foundation, eliminating the need for processing, installation, and dismantling of traditional formwork, simplifying the structure and making construction operations easier.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2 As shown, a drainage ditch structure for steep slope construction includes reinforcing bars 1, a steel plate 2, a concrete foundation 3, and wooden formwork 4. The steel plate is placed on the steep slope 5, with reinforcing bars welded to its outer wall. The upper part of the reinforcing bars is welded and fixed to the outer wall of the steel plate, while the lower part is inserted into the soil layer of the steep slope, thus fixing the steel plate to the slope. To improve the stability of the steel plate's fixation to the steep slope, a reinforcing bar is welded to each of the left and right sides of the steel plate (the number of reinforcing bars can be increased according to actual construction needs), increasing the stress points of the steel plate and improving connection reliability.

[0015] The insertion depth of the reinforcing bar depends on the needs, but should not be less than 1 / 3 of the exposed portion.

[0016] A groove is formed between the steel plate and the steep slope, and concrete is poured into the groove to form a concrete foundation. After pouring, the inner wall of the steel plate, the top surface of the concrete foundation, and the slope surface together form a drainage ditch to divert water flowing up the steep slope, preventing continuous erosion and reducing the risk of soil instability. Furthermore, to improve the efficiency of water diversion, the top of the concrete foundation is smoothed during pouring.

[0017] Because the surface of the steep slope is uneven, there are several gaps between the bottom edge of the steel plate and the slope. When pouring the concrete foundation, the concrete is prone to leaking through these gaps, increasing the difficulty and cost of construction. Therefore, wooden formwork 4 is added to the inside of the steel plate to seal the gaps between the steel plate and the slope, thus solving the leakage problem during concrete pouring.

[0018] Furthermore, by sequentially connecting several drainage ditch structures during the construction period of steep slopes, the flow of water on the slope can be guided to converge, avoiding the risk of slope instability caused by erosion. Wooden formwork can also be added between the steel plates of adjacent structures to prevent leakage through gaps.

[0019] The outer surfaces of the steel plates and reinforcing bars are coated with paint to form an anti-corrosion coating, thereby improving the service life of the structure.

[0020] This drainage ditch structure uses steel plates as concrete formwork, eliminating the need for traditional formwork processing, installation, and dismantling, thus optimizing the construction process. The "no-excavation trenching" design reduces soil disturbance and lowers construction costs. The entire drainage ditch consists only of reinforcing bars, steel plates, and a concrete foundation, simplifying the core structure.

[0021] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
