[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a rectangular hollow steel casing for horizontal obstacle clearing construction of an underground continuous wall, including a rectangular steel casing 1, a clearing hole 2 is opened on the rectangular steel casing 1, and a closing layer 4 is arranged inside the rectangular steel casing 1 at the clearing hole 2, a reserved hole 5 with a size smaller than the clearing hole 2 is opened on the closing layer 4, and the closing layer 4 can move along the rectangular steel casing 1 under the driving of external force, and steel tail brushes 6 are arranged at the upper and lower ends of the closing layer 4.

[0020] In this embodiment, a horizontal obstacle removal equipment operating space is formed by sinking a rectangular steel casing 1, and the reserved hole 5 of the closed layer 4 can adjust the operating position at any time as needed; the construction method has a reasonable structure, a fast and efficient construction process, and is convenient for obstacle removal operations at different locations, greatly improving the utilization rate of construction resources.

[0021] In one embodiment, sealing grease is applied on the steel tail brush 6 to form a seal.

[0022] This embodiment is configured in this way, and the configuration of the steel tail brush 6 can improve the sealing effect of the sealing layer 4, reduce the loss of sediment, and improve the quality of obstacle removal.

[0023] In one embodiment, a lifting ring 7 is provided on the top of the sealing layer 4, and the sealing layer 4 is lifted by the lifting ring 7 to adjust the height of the reserved hole 5 to change the horizontal obstacle clearance elevation position.

[0024] This embodiment is configured such that, by connecting with the lifting ring 7 through an external device, the position of the closed layer 4 is adjusted according to the obstacle clearance requirements, thereby changing the obstacle clearance position to meet different obstacle clearance requirements.

[0025] In one embodiment, a connecting piece 3 is provided on both the rectangular steel casing 1 and the sealing layer 4 , and the two are connected in a limited position by the connecting piece 3 .

[0026] In one embodiment, see Figure 4 , the connecting piece 3 is a U-shaped lock. Specifically, the U-shaped lock should be connected to the inner wall of the rectangular steel casing 1 by welding before leaving the factory, and the size of the obstacle clearance hole 2 is a clearance hole of the size matching the obstacle clearance surface, the hole height is slightly larger than the maximum height of the obstacle clearance surface, and the width is slightly wider than the width of the extended structure of the obstacle clearance machine.

[0027] In one embodiment, the sealing layer 4 is a steel plate structure whose length and width are adapted to the inner space of the rectangular steel casing 1. When the sealing layer 4 is lifted to the maximum height, the steel tail brush 6 is still lower than the lowest point of the obstacle clearance hole 2 opened on the rectangular steel casing 1.

[0028] The specific operation of this application plan is carried out according to the following steps:

[0029] Step 1: Open an obstacle clearance hole 2 on the rectangular steel casing 1, and ensure that the size of the obstacle clearance hole 2 is consistent with the size of the area to be cleared.

[0030] The second step: open a reserved hole 5 on the closed layer 4, the size of the reserved hole 5 should be the same as that of the horizontal obstacle removal equipment, and the same as the third step: apply sealing grease to the steel tail brush 6 on the closed layer 4.

[0031] Step 4: Fit the sealing layer 4 and the rectangular steel casing 1 tightly together through the U-shaped lock, while ensuring that the bottom edge of the obstacle clearance hole 2 and the bottom edge of the reserved hole 5 are at the same elevation.

[0032] Step 5: Sink the rectangular steel casing 1 to ensure that the obstacle clearance hole 2, the reserved hole 5 and the obstacle clearance operation surface are at the same level.

[0033] Step 6: Hoist the horizontal obstacle clearing equipment to the obstacle clearing operation surface, ensure that the horizontal obstacle clearing equipment is flush with the obstacle clearing hole 2 and the reserved hole 5, then start the horizontal obstacle clearing equipment and carry out obstacle clearing operations.

[0034] Step 7: After the obstacle removal is completed, the closed layer 4 is adjusted through the lifting ring 7 so that its elevation is adjusted to the second clearing position, and the horizontal obstacle removal equipment is hoisted for the second obstacle removal.

[0035] Step 8: Repeat the previous seven steps until the obstacle removal operation is completed. At this time, repeated obstacle removal construction is achieved by lifting the closed layer 4, and the construction process is convenient and economical.
