[0002] At present, the enclosure during the excavation of urban underground space has begun to transition from all cast-in-place reinforced concrete continuous walls to partially recyclable steel continuous walls. The removal of steel continuous walls is a key link in the construction process of recyclable steel continuous walls. Different site environments, construction budgets, and construction period requirements will have a huge impact on the removal of steel continuous walls.

[0029] In more detail, the device for removing the steel underground continuous wall comprises a first pad 1, a lifting member 2, a crossbeam 3 and a steel rope 4. The first pad 1 is arranged on both sides of the steel underground continuous wall along the length direction of the steel underground continuous wall, and at least two of the lifting members 2 are connected to the first pad 1 on each side. The crossbeam 3 is used to connect the lifting members 2 on different sides, and one crossbeam 3 is correspondingly connected to two lifting members 2. In this embodiment, the device mainly applies an upward jacking force through four lifting members 2. The crossbeam 3 is provided with a lifting ring 31, and the lifting ring 31 is used to cooperate with the steel rope 4 to connect the steel underground continuous wall, and the lifting ring 31 is arranged on the side of the crossbeam 3 facing the steel underground continuous wall. The lifting member 2 is lifted and extended along the height direction of the first pad 1, driving the height position of the crossbeam 3 to change; the crossbeam 3 is connected to the steel rope 4 for connecting the steel underground continuous wall.

[0030] The device for removing the steel underground continuous wall also includes a second pad 5, a vertical beam 6 and an anchor rod 7. The second pad 5 is arranged parallel to the outside of the first pad 1, that is, the positional relationship between the first pad 1, the second pad 5 and the steel underground continuous wall is that the second pad 5 is farther from the steel underground continuous wall, the first pad 1 is closer to the steel underground continuous wall, and the first pad 1 and the second pad 5 are symmetrically distributed on both sides of the steel underground continuous wall. The second pad 5 is connected to the cross beam 3 through the vertical beam 6. The jacking member 2 and the vertical beam 6 are fixedly connected to the cross beam 3 through fasteners 8, respectively.

[0031] Furthermore, the first pad 1 and the second pad 5 both include a top pad 11, a middle pad 12 and a bottom pad 13. It should be emphasized that the top pad 11, the middle pad 12 and the bottom pad 13 included in the first pad 1 and the second pad 5 are the same, so in this embodiment, the first pad 1 is mainly used as an example for detailed description. The top pad 11, the middle pad 12 and the bottom pad 13 are sequentially stacked and assembled along the height direction of the steel underground continuous wall; at least one middle pad 12 is connected between the top pad 11 and the bottom pad 13.

[0032] A groove 111 is provided on the side of the top gasket 11 facing away from the middle gasket 12. The groove 111 is used to engage the jacking member 2 and the vertical beam 6. In detail, the end of the jacking member 2 facing away from the cross beam 3 is connected and fixed to the top gasket 11 at the position of the groove 111 by a fastener 8, and the end of the vertical beam 6 facing away from the cross beam 3 is connected and fixed to the top gasket 11 at the position of the groove 111 by a fastener 8. A first recess 112 is provided on the side of the top gasket 11 facing the middle gasket 12, and a first protrusion 131 is provided on the side of the bottom gasket 13 facing the middle gasket 12; the top gasket 11 and the bottom gasket 13 can be fixed by the engagement of the first recess 112 and the first protrusion 131. It is worth noting that the upper end surface of the middle gasket 12 is provided with a second protrusion 121, and the lower end surface of the middle gasket 12 is provided with a second depression 122. The first depression 112 of the top gasket 11 and the second protrusion 121 of the middle gasket 12 are engaged with each other, and the first protrusion 131 of the bottom gasket 13 and the second depression 122 of the middle gasket 12 are engaged with each other, so as to realize the plug-in connection between the middle gasket 12 and the upper and lower gaskets. It can be understood that when multiple middle gaskets 12 need to be stacked between the top gasket 11 and the bottom gasket 13, each middle gasket 12 is connected in series through the second protrusion 121 and the second depression 122. In layman's terms, each gasket is assembled and fixed by concave-convex engagement. The anchor rod 7 is arranged at one end of the bottom gasket 13 close to the ground, one end of the anchor rod 7 is fixed to the bottom gasket 13, and the other end is used to insert into the ground soil layer. In this embodiment, the lifting member 2 is preferably a jack, and the fastener 8 is preferably a bolt.

[0033] In this embodiment, a method for using the device for removing a steel underground continuous wall is also provided, comprising the following steps:

[0034] Step 1: Arrange the bottom gaskets 13 on both sides of the steel underground continuous wall, with two bottom gaskets 13 arranged in parallel on each side, and stack the top gasket 11 on the bottom gasket 13.

[0035] Step 2: Install the jacking pieces 2 at intervals on the two top gaskets 11 near the steel underground continuous wall. According to the construction requirements, at least two jacking pieces 2 are installed on each top gasket 11. The crossbeams 3 are erected on the jacking pieces 2 located on both sides of the steel underground continuous wall and connected to the jacking pieces 2. One crossbeam 3 is connected to two jacking pieces 2.

[0036] Step 3: Connect one end of the steel rope 4 to the steel underground continuous wall, and the other end to the lifting ring 31 of the beam 3.

[0037] Step 4: Pressurize the jacking member 2, lift the cross beam 3 upward, and when the height position of the cross beam 3 stops changing, install the vertical beam 6 on the two top gaskets 11 away from the steel underground continuous wall. The vertical beam 6 is fixed in the groove 111 of the top gasket 11 by bolts.

[0038] Step 5: depressurize the lifting member 2 and shorten the extension distance of the lifting member 2 so that the top gasket 11 connected to the lifting member 2 is separated from the bottom gasket 13, and the middle gasket 12 is stacked and assembled in the gap between the top gasket 11 and the bottom gasket 13 until the gap is filled.

[0039] Step six, pressurize the lifting member 2, the cross beam 3 is lifted upward, driving the top gasket 11 connected to the vertical beam 6 to separate from the bottom gasket 13, and superimpose and assemble the middle gasket 12 in the gap between the top gasket 11 and the bottom gasket 13 until the gap is filled.

[0040] Step 7: loop the steps 5 and 6, and stack and assemble the middle gasket 12 in the gap between the top gasket 11 and the bottom gasket 13 until the steel underground continuous wall is pulled out of the groove.

[0041] It should be noted that before executing step one, several construction preparations need to be carried out. The top gasket 11, the middle gasket 12 and the bottom gasket 13 of the device, as well as some steel components involved in the device are designed and processed in advance, and then transported to the construction site. Then, according to the environmental conditions of the construction site, the areas on both sides of the steel underground continuous wall to be removed are leveled, and the weak strata on both sides are reinforced. Then, the areas on both sides of the steel underground continuous wall are measured and laid out to further accurately locate the layout position of the device. In this embodiment, when the middle gasket 12 is superimposed and assembled into the gap between the top gasket 11 and the bottom gasket 13, the protrusions and grooves 111 on the upper and lower surfaces are aligned, and then inserted from the side.

[0042] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
