Description

Technical Field

[0001] The present application relates to the field of steel cages, and in particular to an underground continuous wall steel cage structure that is convenient for pipe roofs to pass through. Background Art

[0002] The main function of the steel cage is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension.

[0003] In construction, pile driving is usually carried out first, by using machine punching and water grinding to drill holes, and the hole depth meets the design requirements, then lowering the steel cage into the pile hole, and then inserting the guide tube to pour concrete. Usually we call the pre-made steel structure such as bored piles, bored piles, and columns as steel cages.

[0004] Underground continuous wall is also called ground-connected wall. When encountering ancient trees during subway construction, it is necessary to pre-dig tunnels on the four sides of the underground of the ancient trees, and then put in multiple parallel steel cages in sequence, and cast the ground-connected wall with the steel cages as the basis. However, multiple steel cages are independent, which makes it difficult to position them when they are put in, and the steel cages are not stable after being put in, which makes it inconvenient for construction. For this reason, this application proposes an underground continuous wall steel cage structure that is convenient for pipe sheds to pass through. Utility Model Content

[0005] In order to facilitate the placement of multiple steel cages into a channel and improve the stability of the steel cages after placement, the present application provides an underground continuous wall steel cage structure that is convenient for a pipe roof to pass through.

Among two adjacent unit cage bodies, a T-bar is fixedly connected to the side wall of one of the unit cage bodies, and a T-slot for inserting the T-bar is opened on the side wall of the other unit cage body.

[0008] By adopting the above technical solution, when setting the steel cage in the channel, the unit cage bodies are placed in the dug channel in sequence. When each unit cage body is placed, the T-bars and T-slots on the two adjacent unit cage bodies are aligned, so that multiple steel cages can be placed in the channel in an orderly manner, and multiple unit cage bodies can be connected as a whole, thereby improving the overall stability of the steel cage.

[0009] Optionally, the plurality of unit cage bodies in a “U”-shaped array are divided into four columns, wherein two opposite columns of unit cage bodies are first cage bodies, and the other two opposite columns are second cage bodies, and the first cage bodies are located between the two columns of second cage bodies;

[0010] Steel plates are fixedly arranged on both sides of the first cage in the thickness direction, and mounting openings are opened on the steel plates. A shelf pipe is arranged on the first cage, and both ends of the shelf pipe are respectively installed in the mounting openings on the two rows of the first cage.

[0011] By adopting the above technical solution and setting up shed pipes, the bottom of the ancient tree can be supported, thereby facilitating construction under the shed pipes for other purposes, such as building aisles.

[0012] Optionally, a plurality of weight-reducing through grooves are provided on the T-bar, and the plurality of weight-reducing through grooves are provided along the height direction of the T-bar.

[0013] By adopting the above technical solution, weight can be reduced while saving materials and costs.

[0014] Optionally, a positioning anchor rod is fixedly provided at the bottom of the unit cage body, and the positioning anchor rod is inserted under the ground.

[0015] By adopting the above technical solution, the positioning anchor rods can position and limit the unit cage body, thereby improving the stability of the unit cage body when placed in the channel, and further improving the overall stability of the steel cage.

[0016] Optionally, both ends of the shelf pipe are welded in the installation opening.

[0017] The adoption of the above technical solution helps to improve the connection strength between the shelf pipes and the unit cage.

[0018] Optionally, one end of the shed pipe is closed and the other end is open; a grouting hole is opened on the peripheral side wall in the middle of the shed pipe, and the grouting hole is connected to the interior of the shed pipe.

[0019] By adopting the above technical solution, after the shed pipes are installed on the unit cage, grouting is injected into the shed pipes, and the slurry flows into the soil at the shed pipes from the grouting holes. After the slurry solidifies, multiple shed pipes and the soil at the shed pipes are connected as a whole, thereby improving the supporting strength of the shed pipes.

[0020] Optionally, the grouting holes are located at the lower side of the rack pipe and multiple rows are arranged on each rack pipe.

[0021] By adopting the above technical solution, multiple rows of grouting holes are provided on each shed pipe, which helps to improve the grouting efficiency.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses an underground continuous wall steel cage structure that is convenient for pipe roofs to pass through. Figure 1-4A steel cage structure for an underground continuous wall that is convenient for a pipe roof to pass through comprises a plurality of unit cage bodies 1 arranged in a U-shaped array. Among two adjacent unit cage bodies 1, a T-bar 2 is fixedly connected to the side wall of one of the unit cage bodies 1, and a T-slot 3 for inserting the T-bar 2 is provided on the side wall of the other unit cage body 1.

[0035] When setting the steel cage in the channel, the unit cage bodies 1 are placed in the dug channel in sequence. When each next unit cage body 1 is placed, the T-bars 2 and T-slots 3 on the two adjacent unit cage bodies 1 are aligned, so that multiple steel cages can be placed in the channel in an orderly manner, and multiple unit cage bodies 1 can be connected as a whole, thereby improving the overall stability of the steel cage.

[0036] The T-bar 2 is provided with a plurality of weight-reducing slots 21, which are provided along the height direction of the T-bar 2. The provision of the weight-reducing slots 21 can reduce weight, save materials, and save costs. The bottom of the unit cage 1 is fixedly connected with a positioning anchor rod 11, which is inserted under the ground. The positioning anchor rod 11 can position and limit the unit cage 1, thereby improving the stability of the unit cage 1 placed in the channel, and further improving the overall stability of the steel cage.

[0037] The multiple unit cage bodies 1 in a "U"-shaped array are divided into four columns, wherein the two opposite columns of unit cage bodies 1 are the first cage bodies 12, and the other two opposite columns are the second cage bodies 13, and the first cage body 12 is located between the two columns of the second cage bodies 13. Steel plates 4 are fixedly provided on both sides of the first cage body 12 in the thickness direction, and mounting openings 5 ​​are provided on the steel plates 4. A shed pipe 6 is provided on the first cage body 12, and the two ends of the shed pipe 6 are respectively installed in the mounting openings 5 ​​on the two columns of the first cage bodies 12. The shed pipe 6 is provided to support the bottom of the ancient tree, so that it is convenient to carry out construction under the shed pipe 6 for other purposes, such as building a corridor. The two ends of the shed pipe 6 are welded in the mounting opening 5, which helps to improve the connection strength between the shed pipe 6 and the unit cage body 1. The size of the steel plate 4 and the shed pipe 6, as well as the spacing between the shed pipes 6 can be set according to actual conditions.

[0038] One end of the scaffolding pipe 6 is closed, and the other end is open; a grouting hole 61 is opened on the peripheral side wall of the middle part of the scaffolding pipe 6, and the grouting hole 61 is connected with the inside of the scaffolding pipe 6. After the scaffolding pipe 6 is installed on the unit cage 1, grouting is injected into the scaffolding pipe 6, and the slurry flows from the grouting hole 61 into the soil at the scaffolding pipe 6. After the slurry solidifies, multiple scaffolding pipes 6 and the soil at the scaffolding pipes 6 are connected as a whole, thereby improving the supporting strength of the scaffolding pipe 6.

[0039] The grouting holes 61 are located on the lower side of the scaffolding pipe 6 and multiple rows are arranged on each scaffolding pipe 6. In the embodiment of the present application, there are three rows of grouting holes 61 on each scaffolding pipe 6. Multiple rows of grouting holes 61 help to improve the grouting efficiency. The grouting holes 61 located on the lower side of the scaffolding pipe 6 help to inject the slurry into the soil under the scaffolding pipe 6, so that the slurry is not easy to overflow to the top of the scaffolding pipe 6, thereby reducing damage to the roots of ancient trees above the scaffolding pipe 6.

[0040] The openings of the three rows of grouting holes 61 are oriented in different directions, and the openings of the grouting holes 61 are oriented vertically downward or obliquely downward. In the embodiment of the present application, the grouting holes 61 in the middle row are located at the bottom of the shelf pipe 6 and the openings are oriented vertically downward. The openings of the other two rows of grouting holes 61 are oriented obliquely downward and are symmetrical about the vertical plane where the axis of the shelf pipe 6 is located, which facilitates the injection of slurry into multiple directions on the lower side of the shelf pipe 6, and helps the shelf pipes 6 to be connected as a whole.

[0041] The implementation principle of an underground continuous wall steel cage structure that is convenient for pipe roofs to pass through in an embodiment of the present application is as follows: when setting the steel cage in the channel, the unit cage bodies 1 are sequentially placed in the excavated channel, and each time the next unit cage body 1 is placed, the T-bars 2 and T-slots 3 on the two adjacent unit cage bodies 1 are aligned, so as to facilitate the orderly placement of multiple steel cages into the channel, and connect the multiple unit cage bodies 1 into a whole, thereby improving the overall stability of the steel cage.

[0042] Then, the scaffolding pipe 6 is passed through the installation opening 5, and the two ends of the scaffolding pipe 6 are welded to the installation opening 5, which can support the bottom of the ancient tree. After the scaffolding pipe 6 is installed on the unit cage 1, grouting is injected into the scaffolding pipe 6, and the slurry flows into the soil at the scaffolding pipe 6 from the grouting hole 61. After the slurry solidifies, multiple scaffolding pipes 6 and the soil at the scaffolding pipe 6 are connected as a whole to improve the supporting strength of the scaffolding pipe 6.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
