However, the loose earth support device for geotechnical engineering investigation does not have a stable supporting structure when in use, and there is no supporting structure between the base and the flip part. The loose earth cannot be supported when it collapses during engineering investigation, which affects the use effect of the supporting device. Therefore, it is necessary to propose a loose earth support device for engineering investigation to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a loose earthwork support device for engineering investigation includes a first hinged plate 1, a second hinged plate 3 is movably installed at the bottom of the first hinged plate 1, a first support plate 2 and a second support plate 4 are respectively sleeved on the outer surfaces of the first hinged plate 1 and the second hinged plate 3, and a stable support structure 13 is movably installed between the first support plate 2 and the second support plate 4;

[0022] The stable support structure 13 includes a support sleeve 9, which is movably installed between the first support plate 2 and the second support plate 4. The internal thread of the support sleeve 9 is connected with the first threaded rotating rod 131 and the second threaded rotating rod 133. The ends of the first threaded rotating rod 131 and the second threaded rotating rod 133 that are away from each other are movably installed with hinge blocks 8.

[0023] In specific implementation, by setting the first hinge plate 1 and the second hinge plate 3, when in use, by pushing the movable handle 12, the first hinge plate 1 and the second hinge plate 3 are driven to slide inside the first support plate 2 and the second support plate 4 respectively, thereby expanding the support area formed between the first hinge plate 1 and the second hinge plate 3 and the first support plate 2 and the second support plate 4 respectively, thereby increasing the support area between the first hinge plate 1 and the second hinge plate 3 and the first support plate 2 and the second support plate 4 respectively and the loose earthwork. The expansion of the support area can improve the safety of the staff when conducting engineering surveys.

[0024] By setting up the stable support structure 13, when in use, the user needs to hold the fixed handle 7 tightly to rotate it when the first hinge plate 1 and the second hinge plate 3 are unfolded with the first support plate 2 and the second support plate 4. The fixed handle 7 will drive the support sleeve 9 to rotate, and the internal thread 134 inside the support sleeve 9 will be threadedly connected with the first threaded rotating rod 131 and the second threaded rotating rod 133.

[0025] Since the thread directions of the first threaded rotating rod 131 and the second threaded rotating rod 133 are the same, when the supporting sleeve 9 is rotated, the first threaded rotating rod 131 and the second threaded rotating rod 133 are driven to move in different directions, and the lengths of the first threaded rotating rod 131 and the second threaded rotating rod 133 are continuously extended, causing the first support plate 2 and the second support plate 4 to move to different positions for support. Through the stable support structure 13, the first hinged plate 1 and the first support plate 2 and the second hinged plate 3 and the second support plate 4 can be stably supported, thereby improving the stability of the support for loose earth.

[0026] When implementing, follow these steps:

[0027] 1) First, hold the fixed handle 7 tightly and rotate it, so that the fixed handle 7 will drive the supporting sleeve 9 to rotate;

[0028] 2) Then the internal thread 134 inside the support sleeve 9 is threadedly connected with the first threaded rotating rod 131 and the second threaded rotating rod 133, because the threads of the first threaded rotating rod 131 and the second threaded rotating rod 133 are of the same length;

[0029] 3) driving the first threaded rotating rod 131 and the second threaded rotating rod 133 to move in different directions, so that the lengths of the first threaded rotating rod 131 and the second threaded rotating rod 133 are continuously extended;

[0030] 4) Finally, the first support plate 2 and the second support plate 4 are moved to different positions for support. Through the stable support structure 13, the first hinged plate 1 and the first support plate 2 and the second hinged plate 3 and the second support plate 4 can be stably supported to improve the stability of the loose earth support.

[0031] To sum up, the loose earth support device for engineering investigation is provided with a first hinged plate 1 and a second hinged plate 3. When in use, by pushing the movable handle 12, the first hinged plate 1 and the second hinged plate 3 are driven to slide inside the first support plate 2 and the second support plate 4 respectively, thereby expanding the support area formed between the first hinged plate 1 and the second hinged plate 3 and the first support plate 2 and the second support plate 4 respectively, thereby increasing the support area between the first hinged plate 1 and the second hinged plate 3 and the first support plate 2 and the second support plate 4 respectively and the loose earth. The expansion of the support area can improve the safety of the staff when conducting engineering investigation.

[0032] Furthermore, by providing a stable support structure 13, when in use, the user needs to rotate the first hinge plate 1 and the second hinge plate 3 and the first support plate 2 and the second support plate 4 by holding the fixed handle 7 tightly, and the fixed handle 7 will drive the support sleeve 9 to rotate, and the internal thread 134 inside the support sleeve 9 will be threadedly connected with the first threaded rotating rod 131 and the second threaded rotating rod 133. Since the thread directions of the first threaded rotating rod 131 and the second threaded rotating rod 133 are the same, when the support sleeve 9 is rotated, the first threaded rotating rod 131 and the second threaded rotating rod 133 are driven to move in different directions, and the lengths of the first threaded rotating rod 131 and the second threaded rotating rod 133 are continuously extended, causing the first support plate 2 and the second support plate 4 to move to different positions for support. Through the stable support structure 13, the first hinge plate 1 and the first support plate 2 and the second hinge plate 3 and the second support plate 4 can be stably supported, thereby improving the stability of supporting loose earth.
