Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.
[0039] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.
[0040] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] As a pipeline equipment for transporting liquids, water pipes are widely used in industries, construction, agriculture, and households. It can transport water or other liquids from one place to another with low transportation costs, which provides convenience for our lives and production.
[0042] During the construction process, water pipes are usually buried directly in the original soil due to considerations of construction convenience and cost.
[0043] However, in areas of high cold and severe freezing, the original soil on the surface of the ground is frozen. To prevent the water pipes from being damaged by frost heave, the water pipes cannot be buried directly in the frozen soil layer. To avoid this problem, the pipes generally need to be buried below the frozen soil layer, which will cause the basement roof elevation to be lowered and the floor height to be reduced, which cannot meet the functional requirements of the building. Otherwise, the basement burial depth needs to be increased, which will greatly increase the construction cost. For this reason, a pipe trench structure suitable for frozen soil areas is needed.
[0044] In order to solve the above problems, an embodiment of the present application provides a pipe trench structure suitable for frozen soil areas. The solution provided by the embodiment of the present application will be described below in conjunction with the drawings in the specification.
[0045] Figure 1 It is a structural schematic diagram of a pipe trench structure suitable for frozen soil areas provided in one embodiment of the present application.
[0046] Reference Figure 1 As shown, an embodiment of the present application provides a pipe trench structure suitable for frozen soil areas, including a bottom plate 100 , a first side wall 200 , a second side wall 300 , a top cover 400 and a cushion layer 500 .
[0047] The bottom plate 100 is disposed in the frozen soil layer 600. The bottom plate 100 may be a concrete plate, and in some examples, the bottom plate 100 is a top plate of a basement.
[0048] The first side wall 200 and the second side wall 300 are arranged on the bottom plate 100 in a relative manner, and the top cover 400 is buckled on the first side wall 200 and the second side wall 300. The bottom plate 100, the first side wall 200, the second side wall 300 and the top cover 400 enclose a pipeline placement space; the first side wall 200 and the second side wall 300 can be concrete slabs, which are arranged in a relative manner, and the distance between the first side wall 200 and the second side wall 300 can be set as needed. Exemplarily, the top cover 400 can also be a reinforced concrete slab.
[0049] The bottom plate 100, the first side wall 200, the second side wall 300 and the top cover 400 enclose a space with two ends connected, which is configured as a pipeline placement space for placing a pipeline 700, such as a water pipe. The side of the first side wall 200 facing away from the pipeline placement space is a frozen soil layer 600, and the side of the second side wall 300 facing away from the pipeline placement space is a frozen soil layer 600. The first side wall 200 and the second side wall 300 isolate the pipeline 700 from the frozen soil of the frozen soil layer 600.
[0050] In addition, the cushion layer 500 is arranged at the bottom of the pipeline placement space, that is, the side of the bottom plate 100 facing the pipeline placement space, and the pipeline 700 is placed on the cushion layer 500. Exemplarily, the cushion layer 500 can be a plain concrete layer, which is arranged on the bottom plate 100 by pouring. In order to improve the anti-freezing and heaving ability of the pipeline 700, an insulation layer can also be coated on the surface of the pipeline 700.
[0051] It is understandable that the pipe trench structure can isolate the pipeline 700 from the frozen soil of the frozen soil layer 600, avoiding direct contact between the pipeline 700 and the frozen soil, thereby avoiding the problem of frost heave damage to the pipeline 700 in the harsh frozen soil layer 600. In addition, since the top cover 400 is movably arranged on the first side wall 200 and the second side wall 300, it is convenient to open the pipeline placement space and inspect the pipeline 700, reducing the workload of inspecting and maintaining the pipeline 700, and also avoiding the damage to the frozen soil layer 600 caused by the inspection of the pipeline 700.
[0052] Figure 2 Figure 1 Schematic diagram of the structure of the first side wall 200.
[0053] Reference Figure 1 and Figure 2 As shown, the first side wall 200 includes a first body 210 and a first stopper 220, and the first stopper 220 is disposed on the first body 210. Exemplarily, the first stopper 220 is located on the upper surface of the first body 210, and the first stopper 220 is integrally disposed with the first body 210. For example, the first body 210 and the first stopper 220 may be integrally cast.
[0054] The second side wall 300 includes a second body 310 and a second stopper 320, and the second stopper 320 is disposed on the second body 310. Exemplarily, the second stopper 320 is located on the upper surface of the second body 310, and the second stopper 320 is integrally disposed with the second body 310. For example, the second body 310 and the second stopper 320 may be integrally cast.
[0055] Exemplarily, the first limiting block 220 and the second limiting block 320 are positioned opposite to each other and form a limiting space, and the top cover 400 is placed in the limiting space. It is understandable that due to the presence of the first limiting block 220 and the second limiting block 320, the top cover 400 can be limited, which facilitates the placement of the top cover 400 and prevents it from sliding.
[0056] Continue to refer to Figure 1 and Figure 2 As shown, the first body 210 includes a first contour rib 212 and a first concrete layer 211 .
[0057] The first contour rib 212 is located in the first concrete layer 211, thereby improving the strength and rigidity of the first concrete layer 211 and improving its bearing capacity. In addition, the first fixed end 2121 of the first contour rib 212 extends out from the first concrete layer 211, and the first fixed end 2121 is fixedly disposed in the bottom plate 100, thereby fixing the first concrete layer 211 on the bottom plate 100.
[0058] The second body 310 includes a second contour rib 312 and a second concrete layer 311; the second contour rib 312 is located in the second concrete layer 311, thereby improving the strength and rigidity of the second concrete layer 311 and improving its bearing capacity. The second fixed end 3121 of the second contour rib 312 also extends from the second concrete layer 311, and the second fixed end 3121 is fixedly disposed in the bottom plate 100, so that the second concrete layer 311 is fixed on the bottom plate 100. Exemplarily, the first fixed end 2121 and the second fixed end 3121 can be directly cast by concrete and fixed in the bottom plate 100.
[0059] In some examples, the first fixing end 2121 and the second fixing end 3121 are both bent, for example, 90 degrees, to form an anchor claw, thereby improving the connection strength between the first fixing end 2121 and the second fixing end 3121 and the bottom plate 100 .
[0060] Continue to refer to Figure 1 and Figure 2 As shown, in some examples, reinforcing ribs 800 are provided in the first limit block 220 and the second limit block 320. The reinforcing ribs 800 may be located on additional short ribs extending from the first contour rib 212 or the second contour rib 312, thereby improving the durability of the first limit block 220 and the second limit block 320.
[0061] In addition, illustratively, the first body 210 and the second body 310 both include additional ribs 900, which are respectively disposed on the first contour rib 212 and the second contour rib 312. Specifically, the additional ribs 900 are disposed on the inner side and the bend of the first contour rib 212 and the second contour rib 312 to improve the rigidity of the first body 210 and the second body 310 and prevent cracks from occurring therein.
[0062] Figure 3 yes Figure 1 Cross-sectional view of a trench structure suitable for frozen soil areas.
[0063] Reference Figure 3 As shown, in some examples, the cushion layer 500 on the bottom plate 100 has a certain slope, and the thickness of the cushion layer 500 gradually decreases along the flow direction of the liquid in the pipeline 700, thereby facilitating the flow of the liquid in the pipeline 700.
[0064] Continue to refer to Figure 1 As shown, the pipe trench structure further includes a first waterproof layer 1000, a second waterproof layer 1100 and a third waterproof layer 1200. The first waterproof layer 1000 is arranged on the side of the first side wall 200 facing away from the pipe placement space; the second waterproof layer 1100 is arranged on the side of the second side wall 300 facing away from the pipe placement space; the third waterproof layer 1200 is arranged on the bottom plate 100 and is located between the frozen soil layer 600 and the bottom plate 100. The first waterproof layer 1000, the second waterproof layer 1100 and the third waterproof layer 1200 can be made of asphalt waterproofing membranes available on the market, which can prevent external water from penetrating into the pipe placement space, thereby protecting the internal pipes 700.
[0065] Figure 4 yes Figure 1 Top view of the trench structure suitable for frozen soil areas.
[0066] Reference Figure 1 and Figure 4As shown, the top cover 400 also includes a handle, which is arranged on the top cover 400 to facilitate moving the top cover 400. Exemplarily, the handle can be arranged at the center of the top cover 400.
[0067] In addition, in some examples, there are multiple top covers 400, and the multiple top covers 400 are arranged in sequence along the extension direction of the side wall, and the sides of adjacent top covers 400 are in contact. Figure 4 The x direction is shown in .
