Description

Technical Field

[0001] This utility model relates to the technical field of municipal drainage structures, and in particular to a structure for opening a partial lower side wall of a protective wall. Background Technology

[0002] Currently, in the process of municipal road construction, there is a problem of widening existing roads. The common widening methods are backfilling soil and sill-slab construction. However, in special road widening, especially in areas with strict settlement control, such as the widening of embankments during the construction of canals or lakes, a large amount of additional stress will be generated, causing excessive road settlement and even road settlement cracking.

[0003] To reduce excessive additional stress on the roadbed caused by the fill material and control road settlement, a treatment method using foamed lightweight soil and a protective wall structure along the roadside can be adopted. Simultaneously, to ensure unobstructed municipal drainage, the protective wall structure needs to be partially lowered and have openings in the side walls. This utility model provides a protective wall structure with lowered side wall openings. Furthermore, this structure is applicable to opening treatments in other reinforced concrete structures, making it a widely applicable and safe structural treatment method. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a structure with a partial lower side wall opening in the protective wall, which not only ensures the stability of the road structure but also solves the problem of the protective wall structure obstructing municipal drainage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A protective wall partially lowered sidewall opening structure includes a cushion layer set on the foundation, a standard section protective wall structure set on the cushion layer, a lowered section protective wall structure longitudinally penetrating the standard section protective wall structure, and the lowered section protective wall structure extending downward into the foundation, deformation joints forming between the two sides of the lowered section protective wall structure and the corresponding side of the standard section protective wall structure, a backfill layer is set in the height difference area formed between the part of the lowered section protective wall structure extending into the foundation and the standard section protective wall structures on the adjacent two sides, a transversely penetrating opening structure is provided in the lower part of the lowered section protective wall structure, and a water pipe channel for installing a drainage pipe is provided in the lowered section protective wall structure below the opening structure.

[0006] The beneficial effects of this utility model are as follows: The protective wall partially lowered side wall opening structure of this utility model adopts a partial lowering method of setting a lower section protective wall structure on the standard section protective wall structure, and sets an opening structure in the lower section protective wall structure, and sets a water pipe channel for installing drainage pipes below the opening structure in the lower section protective wall structure. It is convenient to construct, highly safe and economical, can ensure the stability of road embankments, and at the same time ensure the smooth drainage of municipal pipe networks, achieving good economic and social benefits, with a wide range of applications and reliable safety.

[0007] Based on the above technical solution, the present invention can be further improved as follows:

[0008] Furthermore, both the standard section protective wall structure and the lower section protective wall structure are cast-in-place reinforced concrete structures.

[0009] The beneficial effects of the above-mentioned further solutions are: using cast-in-place reinforced concrete structures is convenient for construction and has mature technology, while also having relatively low labor costs and controllable overall costs.

[0010] Further: The expansion joint is caulked with oil-impregnated wood fiberboard and then sealed.

[0011] The beneficial effects of the above-mentioned further solutions are: oil-impregnated wood wool boards have excellent waterproof performance, which can effectively prevent water penetration, protect the whole from erosion, have high elasticity, are easy to construct, and have a long service life.

[0012] Further: The width of the expansion joint is 15-25mm.

[0013] Furthermore, the backfill layer is constructed using C20 plain concrete cast-in-place.

[0014] The beneficial effect of the above-mentioned further scheme is that: using C20 plain concrete for in-situ backfilling can protect the elevation difference zone formed between the part of the lower section protective wall structure that extends into the foundation and the standard section protective wall structure on the adjacent sides, thus preventing uneven settlement.

[0015] Furthermore, the subbase layer is made of graded crushed stone with a non-uniformity coefficient greater than 5 and a curvature coefficient of 1-3.

[0016] Furthermore, reinforcing ribs are provided around the opening within the perforated structure.

[0017] The beneficial effect of the above-mentioned further solutions is that by setting reinforcing ribs around the opening in the opening structure, the structural stability of the opening structure and the lower section protective wall structure can be further improved.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 3 As shown, a partial lower side wall opening structure for a protective wall includes a cushion layer 5 set on a foundation. A standard section protective wall structure 1 is set on the cushion layer 5. A lower section protective wall structure 2 is longitudinally inserted through the standard section protective wall structure 1 and extends downward into the foundation. Expansion joints 3 are formed between the two sides of the lower section protective wall structure 2 and the corresponding standard section protective wall structure 1. A backfill layer 4 is set in the height difference area formed between the part of the lower section protective wall structure 2 extending into the foundation and the standard section protective wall structure 1 on the adjacent sides. A transverse opening structure 6 is set through the lower part of the lower section protective wall structure 2. A water pipe channel 7 for installing a drainage pipe is set below the opening structure 6 in the lower section protective wall structure 2.

[0025] This utility model's protective wall partial lower side wall opening structure adopts a partial lowering method, setting a lower section protective wall structure 2 on the standard section protective wall structure 1, and setting an opening structure 6 in the lower section protective wall structure 2. A water pipe channel for installing drainage pipes is set below the opening structure 6 in the lower section protective wall structure 2. It is convenient to construct, highly safe and economical, can ensure the stability of road embankments, and at the same time ensure the smooth drainage of municipal pipe networks, achieving good economic and social benefits. It has a wide range of applications and is safe and reliable.

[0026] In one or more embodiments of this utility model, both the standard section protective wall structure 1 and the lower section protective wall structure 2 are cast-in-place reinforced concrete structures. Using cast-in-place reinforced concrete structures offers advantages such as convenient construction, mature technology, relatively low labor costs, and controllable overall cost.

[0027] In this utility model, both the standard section protective wall structure 1 and the lower section protective wall structure 2 are structures perpendicular to the widened embankment, and a formwork support system needs to be erected before casting to ensure the quality of the cast-in-place structure.

[0028] In one or more embodiments of this utility model, the expansion joint 3 is caulked and sealed with oil-impregnated wood wool board. Oil-impregnated wood wool board has excellent waterproof properties, effectively preventing water penetration and protecting the entire structure from erosion. It also has high elasticity, is easy to install, and has a long service life.

[0029] In practice, oil-impregnated wood fiberboard is sealed with polyurethane sealant and coated with two layers of fiberglass cloth and three layers of oil.

[0032] In one or more embodiments of this utility model, the cushion layer 5 is made of graded crushed stone with a non-uniformity coefficient greater than 5 and a curvature coefficient of 1-3. Here, the thickness of the graded crushed stone can be 10cm. It should be particularly noted that the soil layer below the foundation of the cushion layer 5 must meet the design foundation bearing capacity requirements; otherwise, it needs to be treated separately.

[0033] In one or more embodiments of this utility model, reinforcing ribs are provided around the opening in the opening structure 6. By providing reinforcing ribs around the opening in the opening structure 6, the structural stability of the opening structure 6 and the lower protective wall structure 2 can be further improved.

[0034] Here, reinforcing ribs are installed around the opening in the opening structure 6 in the circumferential, longitudinal, and transverse directions to strengthen the structure.

[0035] The specific implementation steps of the protective wall partially lowered side wall opening structure of this utility model are as follows:

[0036] Step 1: Clear and level the site to the bottom elevation of the subbase 5, and excavate below the lower protective wall structure 2 to the design elevation.

[0037] Step 2: Place the reinforcing bars of the lower section protective wall structure 2 and the structural opening area 6, as well as the opening reinforcement bars, and set up the formwork;

[0038] Step 3: Cast-in-place concrete forms the lower section protective wall structure 2 and the opening reinforcement structure 5;

[0039] Step 4: Cast-in-place backfill layer 4 and lay cushion layer 5 in the elevation difference zone formed between the part of the lower section protective wall structure 2 that extends into the foundation and the standard section protective wall structure 1 on both sides.

[0040] Step 5: Apply expansion joint material to form expansion joint 3, and seal the opening with sealant;

[0041] Step Six: Lay the reinforcing bars for the standard section protective wall structure 1 and set up the formwork;
