Description

Technical Field

[0001] The utility model relates to the technical field of building foundation pits, in particular to a channel side wall anti-collapse structure. Background Art

[0002] In the prior art, ditches are a general term for waterways dug for irrigation or drainage. A canal is a common water conservancy construction facility, mainly used to guide water flow. During the construction of a canal, it is generally necessary to dig a channel foundation pit and trench in the soil. However, the digging depth of the canal trench is small, and the top soil is relatively loose, which is prone to collapse.

[0003] After searching, the Chinese patent application number 202310439016.1 discloses a foundation pit anti-collapse support structure for construction, including: a first supporting pile, a second supporting pile, a reinforcement pile, a side plate, a bottom plate and a supporting column. A plurality of the second supporting piles form a second supporting circle along the side wall of the foundation pit. A plurality of the first supporting piles are located on the outside of the second supporting circle and form a first supporting circle along the side wall of the foundation pit. A crown beam is connected above the second supporting pile. The side of the crown beam away from the foundation pit is close to the first supporting pile. The side of the crown beam close to the foundation pit is connected to the first supporting concrete. The bottom of the foundation pit is located on the inner side of the second supporting circle. The reinforcement part is composed of a plurality of the reinforcement piles arranged in an arranged manner. The side plate is fixed to the inner side of the second supporting pile. The bottom plate is fixed above the reinforcement part. The side of the bottom plate away from the second supporting pile is connected to the second supporting concrete. A quick tightening mechanism is arranged above the bottom plate.

[0004] The above patent has the following shortcomings: the various parts of the support structure cooperate with each other, the overall support strength is better, and the risk of collapse can be effectively avoided; the quick tightening mechanism on the bottom plate makes the installation and disassembly of the support more convenient and simple, without the need for too many fasteners for installation and fixation; however, in actual use, the support structure has structures such as the bottom plate and support columns close to the inside of the foundation pit, which will not only increase the area of ​​foundation pit excavation, but also easily affect the masonry of the side walls of the canal, which is not conducive to the overall structural construction.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1: Figure 1 As shown;

[0026] A channel sidewall anti-collapse structure is composed of a plurality of anti-collapse plate groups connected end to end in sequence, the anti-collapse plate group includes two symmetrically arranged collapse blocking plates 1, two positioning installation tubes 2 are welded to one side of the collapse blocking plate 1 close to the channel sidewall, and the two positioning installation tubes 2 are arranged on both sides of the collapse blocking plate 1.

[0027] A positioning bottom arm plate 3 is provided at the bottom end of the two positioning and mounting cylinders 2, and a reinforcing connecting column 4 is integrally formed at the top end of the positioning and mounting cylinder 2. The distance from the bottom end of the positioning and mounting cylinder 2 to the bottom end of the collapse preventing plate 1 is the same as the distance from the top end of the positioning and mounting cylinder 2 to the top end of the collapse preventing plate 1. This distance is the same as the thickness of the positioning bottom arm plate 3, and the reinforcing connecting column 4 is the same height as the positioning and mounting cylinder 2.

[0028] A positioning block 5 is integrally formed at the top of the reinforced connecting column 4 , and a top cross arm plate 6 is clamped on the outside of the positioning block 5 . Both ends of the top cross arm plate 6 are integrally formed with connecting clamps, which are plugged into the top of the positioning installation tube 2 .

[0029] A fixed cutting column 7 is installed inside the positioning installation tube 2. The bottom end of the fixed cutting column 7 passes through the positioning bottom arm plate 3 and extends downward, and the extended end is inserted into the soil at the bottom end of the channel; and the top end of the fixed cutting column 7 passes through the top cross arm plate 6 and extends upward.

[0030] When the device is in use, the height of the collapse barrier plate 1 must be greater than or equal to the depth of the channel to prevent the soil on the top of the channel from falling between the two collapse barrier plates 1; therefore, the collapse barrier plates 1 can be spliced ​​longitudinally with the assistance of the fixed cutting columns 7.

[0031] The above-mentioned collapse prevention plate 1 is a single plate, and a double plate can also be used, that is, two plates are symmetrically arranged on both sides of the positioning and installation cylinder 2. When the channel side wall collapses, it will not affect the disassembly of the anti-collapse plate group.

[0032] Working principle:

[0033] When the device is in use, first determine the distance between two collapse barrier plates 1 in the same group according to the construction drawings of the canal. The distance must be greater than the masonry width of the canal by sixty centimeters so as not to affect the later plastering work on the outer wall of the canal. Then, place a plurality of positioning bottom arm plates 3 at equal intervals in sequence. Then, install and fix the cutting columns 7 corresponding to the positioning bottom arm plates 3. Then, install the collapse barrier plates 1 through the positioning installation tubes 2. Make the collapse barrier plates 1 on the same side first engage in sequence. Finally, install the top cross arm plate 6. If the height of a single collapse barrier plate 1 is greater than the depth of the equidistant channel, the positioning bottom arm plates 3 may not be used.

[0034] Embodiment 2: Figures 2 to 4 As shown;

[0035] On the basis of the first embodiment, a reinforcing cross arm 8 is additionally provided, and the reinforcing cross arm 8 includes an internal threaded grip tube 801 and two fixed connection units, and the main body of the fixed connection unit is configured as a rotating connection head 802, and an external threaded connection column 809 is welded on the side of the rotating connection head 802 close to the internal threaded grip tube 801, and a fastening nut 810 is threadedly sleeved on the outer wall of the external threaded connection column 809.

[0036] The threads at both ends of the inner cavity of the internal threaded grip tube 801 rotate in opposite directions, and two external threaded connecting columns 809 are respectively threadedly installed on the two ends of the inner cavity of the internal threaded grip tube 801. When the internal threaded grip tube 801 is rotated, the two external threaded connecting columns 809 move synchronously in opposite directions, that is, the two external threaded connecting columns 809 approach or move away synchronously; when the fastening nut 810 is in contact with the end of the internal threaded grip tube 801, the two external threaded connecting columns 809 can be prevented from approaching each other.

[0037] A rotating installation groove 803 is provided on both sides of the rotating connecting head 802. A rotating connecting arm 804 is rotatably installed inside the rotating installation groove 803 through a first pin. The other end of the rotating connecting arm 804 is rotatably connected to a rotating connecting ear plate group 805 through a second pin.

[0038] A rotating clamping block 806 is welded to one side of the rotating connecting ear plate group 805 , one end of the rotating clamping block 806 is rotatably connected to a cutting column clamp 807 , and a fixed cross arm 808 is welded between the two cutting column clamps 807 .

[0039] A clamping installation groove is provided on the side of the two cutting column cartridges 807 close to each other, and the rotating clamping block 806 is rotatably installed inside the clamping installation groove; and the cutting column cartridge 807 is sleeved on the top of the fixed cutting column 7.

[0040] Reference Figure 2 The reinforcing cross arm 8 is arranged at the top of the anti-collapse plate group, and the two adjacent fixed cutting columns 7 of two adjacent anti-collapse plate groups are connected to the reinforcing cross arm 8.

[0041] Working principle:

[0042] On the basis of Example 1, when the reinforcement cross arm 8 is in use, firstly, multiple cutting column clamps 807 are correspondingly sleeved on the top ends of multiple fixed cutting columns 7, and then the internal thread gripping tube 801 is rotated clockwise to make the two external threaded connecting columns 809 move away from each other, and the external threaded connecting column 809 squeezes the rotating clamping block 806 by rotating the connecting head 802 and the rotating connecting arm 804, and the rotating clamping block 806 squeezes the fixed cutting column 7, so that the reinforcement cross arm 8 and the fixed cutting column 7 remain stable, and finally the fastening nut 810 is tightened in the direction of the internal thread gripping tube 801 to fix the external threaded connecting column 809; finally, the anti-collapse plate group is kept stable to avoid affecting the stability of the anti-collapse plate group when the channel side wall collapses.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
