Description

Technical Field

[0001] This utility model relates to an installation structure in dike engineering, and more particularly to an installation structure for reinforced concrete box culverts in dike engineering. Background Technology

[0002] Dike engineering refers to water-retaining structures built along the edges of rivers, canals, lakes, coastlines, or floodplains, flood diversion areas, and reclamation areas. In dike engineering, reinforced concrete box culverts are often installed for drainage and water diversion. Existing reinforced concrete box culverts have simple installation structures, mostly laid directly underground. Over time, rainwater erosion can cause these culverts to loosen, affecting the overall quality of the project. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a reinforced concrete box culvert installation structure for dike engineering, which addresses the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following measures:

[0005] An installation structure for a reinforced concrete box culvert in a dike project includes a horizontally installed reinforced concrete box culvert body. Several evenly distributed bored piles are vertically arranged below the reinforced concrete box culvert body to support it. The tops of the bored piles rest on the outer bottom surface of the reinforced concrete box culvert body. Foamed concrete filling layers are provided on both sides of the reinforced concrete box culvert body, with the height of the foamed concrete filling layers lower than the height of the reinforced concrete box culvert body. From bottom to top, a stone slab cushion layer, a cement-aggregate stabilizing layer, and a reinforced concrete approach slab are sequentially arranged on the foamed concrete filling layer. The reinforced concrete approach slab is set at the same height as the reinforced concrete box culvert body. A reinforced concrete pavement layer is laid on the reinforced concrete approach slab and the reinforced concrete box culvert body.

[0006] The reinforced concrete box culvert body is provided with a plain concrete cushion layer and a slag cushion layer below it. The plain concrete cushion layer is set close to the reinforced concrete box culvert body, and the slag cushion layer is located below the plain concrete cushion layer. The bored cast-in-place piles pass through the plain concrete cushion layer and the slag cushion layer and press up to the outer bottom of the reinforced concrete box culvert body.

[0007] Several bored piles are arranged in a matrix;

[0008] The outer bottom surface of the reinforced concrete box culvert body is provided with a positioning groove along the length direction, and the top of the bored piles are distributed in the positioning groove;

[0009] The reinforced concrete box culvert body has L-shaped stepped surfaces on both sides, the cement-crushed stone stabilization layer is set at the same height as the L-shaped stepped surfaces, and the reinforced concrete approach slab is laid on the L-shaped stepped surfaces.

[0010] The widths of the plain concrete cushion layer and the slag cushion layer on both sides exceed the width of the reinforced concrete box culvert body.

[0011] The beneficial effects of this utility model are: novel structure, good stability of the laid reinforced concrete box culvert body, not easy to shake, flat appearance, and overall hidden under the reinforced concrete pavement layer, which improves the quality of the embankment project. Attached Figure Description

[0012] Figure 1 This is a cross-sectional planar structural diagram of the present invention. Detailed Implementation

[0013] A reinforced concrete box culvert installation structure for a dike project includes a horizontally installed reinforced concrete box culvert body 1. Several evenly distributed bored piles 2 are vertically arranged below the reinforced concrete box culvert body 1 to support it. The tops of the bored piles 2 rest on the outer bottom surface of the reinforced concrete box culvert body 1. Foamed concrete filling layers 3 are provided on both sides of the reinforced concrete box culvert body 1. The height of the foamed concrete filling layers 3 is lower than the height of the reinforced concrete box culvert body 1. From bottom to top, a stone slab cushion layer 4, a cement-aggregate stabilizing layer 5, and a reinforced concrete approach slab 6 are sequentially arranged on the foamed concrete filling layers 3. The reinforced concrete approach slab 6 is set at the same height as the reinforced concrete box culvert body 1. A reinforced concrete pavement layer 7 is laid on the reinforced concrete approach slab 6 and the reinforced concrete box culvert body 1.

[0014] like Figure 1 As shown, during the entire construction process, bored piles 2 are first set on the ground. The number of bored piles 2 is reasonably set according to the size of the reinforced concrete box culvert body 1. Usually, the bored piles 2 are arranged in three rows: left, middle and right, in order to achieve better support effect and avoid the reinforced concrete box culvert body 1 from tilting to both sides after long-term use. Then, the slag cushion layer 9 and the plain concrete cushion layer 8 are laid in sequence. The top part of the bored pile 2 is exposed outside the plain concrete cushion layer 8. The height of the exposed part is less than the depth of the positioning groove on the outer bottom surface of the reinforced concrete box culvert body 1. Then, the reinforced concrete box culvert body 1 is placed on the bored pile 2. The top of the bored pile 2 falls into the positioning groove. Foamed concrete filling layer 3 is laid on both sides of the reinforced concrete box culvert body 1. The foamed concrete filling layer 3 is partially pressed onto the plain concrete cushion layer 8. Then, the stone slag cushion layer 4, the cement crushed stone stabilizing layer 5 and the reinforced concrete approach slab 6 are laid in sequence on the foamed concrete filling layer 3. Finally, the reinforced concrete pavement layer 7 is laid to cover the reinforced concrete approach slab 6 and the reinforced concrete box culvert body 1.

[0015] The reinforced concrete box culvert body 1 is provided with a plain concrete cushion layer 8 and a slag cushion layer 9 below it. The plain concrete cushion layer 8 is set close to the reinforced concrete box culvert body 1, and the slag cushion layer 9 is located below the plain concrete cushion layer 8. The bored pile 2 passes through the plain concrete cushion layer 8 and the slag cushion layer 9 and presses against the outer bottom of the reinforced concrete box culvert body 1.

[0016] Several bored piles are arranged in a matrix.

[0017] The outer bottom surface of the reinforced concrete box culvert body 1 is provided with a positioning groove along the length direction, and the top of the bored piles 2 are distributed in the positioning groove.

[0018] The reinforced concrete box culvert body 1 has L-shaped stepped surfaces 101 on both sides, the cement-crushed stone stabilization layer 5 is set at the same height as the L-shaped stepped surfaces 101, and the reinforced concrete slab 6 is laid on the L-shaped stepped surfaces 101.

[0019] The widths of the plain concrete cushion layer 8 and the slag cushion layer 9 on both sides exceed the width of the reinforced concrete box culvert body 1.
