[0015] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. It should be noted that the description of these implementations is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation of the present invention described below can be combined with each other as long as they do not conflict with each other. Embodiment 1:

[0016] See also Figure 1 and Figure 2 , shown in the figure is a construction protection frame for preventing foundation pit earthwork collapse.

[0017] The protective frame for preventing earthwork collapse in foundation pits comprises: a protective frame cover body inside the foundation pit and a movable trolley outside the foundation pit, etc. The movable trolley displaces the protective frame cover body along the length direction of the foundation pit.

[0018] The protective frame cover is a rigid part. The protective frame cover has a peripheral wall and a top wall, but does not have a bottom wall. The range covered by the protective frame cover is the working area of ​​the workers. The workers can carry out construction work on the foundation pit within the range covered by the protective frame cover. If the foundation pit collapses unexpectedly, the collapsed soil will cover the protective frame cover. Since the protective frame cover is a rigid part, it can withstand the load generated by the collapsed soil (the protective frame cover will not deform or will basically not deform), that is, the collapsed soil and the workers are separated by the protective frame cover to prevent the workers from being directly buried. The workers are safe inside the protective frame cover and can wait for ground rescue.

[0019] The movable trolley has a frame and wheels on the left and right sides of the frame. The frame is above the protective frame cover and is fixedly connected to the protective frame cover. The wheelbase of the wheels is greater than the width of the foundation pit. The wheels are against the ground. The movable trolley can drive the protective frame cover to move synchronously. If the construction of the foundation pit inside the protective frame cover at the current position is completed, the protective frame cover can be driven by the movable trolley to move to the next position for subsequent operations. Repeat the cycle until the overall construction of the foundation pit is completed.

[0020] In this embodiment, the protective frame cover adopts a segmented splicing structure, and the segments to be used are selected according to the depth of the foundation pit, and are spliced ​​in sequence from bottom to top. In another embodiment, the protective frame cover is a whole section structure and does not need to be spliced.

[0021] In this embodiment, the movable trolley is an electric trolley, the frame device is equipped with a motor, the motor shaft of the motor is connected to the wheel shaft of the wheel through a gear transmission, that is, the motor drives the wheel to move. In another embodiment, the movable trolley is a human-powered trolley, and the operator pushes or pulls the movable trolley to move by manpower. Embodiment 2:

[0022] See also Figure 3 , the figure shows a construction protection frame for preventing foundation pit earthwork collapse. The difference from embodiment 1 is that: the movable trolley.

[0023] The movable trolley comprises a frame and slider rail pairs on the left and right sides of the frame. The slide rail portion of the slider rail pair is fixed to the ground. The slider portion of the slider rail pair is fixed to the frame. The displacement of the protective frame cover is achieved through the sliding cooperation of the slider rail pair. Embodiment 3:

[0024] See also Figure 4, the figure shows a construction protection frame for preventing foundation pit earthwork collapse. The difference from embodiment 1 is that: the movable trolley.

[0025] The movable vehicle comprises a frame and a gear rack pair on the left and right sides of the frame. The rack portion of the gear rack pair is fixed to the ground. The gear portion of the gear rack pair is fixed to the frame. The displacement of the protective frame cover is achieved through the gear meshing transmission of the gear rack pair. Embodiment 4:

[0026] The difference from the first embodiment is that the movable trolley is abandoned and a crane is used to drive the protective frame cover to move. The crane is fixed on the ground. The hook of the crane hooks the protective frame cover. The crane controls the action of the hook to achieve the displacement of the protective frame cover.

[0027] The above only expresses the implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
