Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and in particular relates to a guide channel support device for the TRD method. Background Technology

[0002] Before excavation using the TRD method, a guide trench needs to be excavated on the ground. In areas with soft surface soil, a support structure also needs to be installed inside the trench. Current support structures, such as the one described in patent CN202420961482.6 (a TRD method pile support structure), use support columns and connecting rods to support the support plates on both sides of the guide trench.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 12 As shown, a guide channel support device for the TRD method includes: Support plate 1, a first connecting pipe 101 is fixedly provided at the lower end of one side of support plate 1, and a second connecting pipe 102 is fixedly provided at the upper end of the other side of support plate 1. Multiple support plates 1 are arranged sequentially along the width direction of support plate 1. The first insertion rod 4 passes through the second connecting pipe 102 of the support plate 1 and the first connecting pipe 101 of the adjacent support plate 1 and is inserted into the bottom end of the guide groove. Wire rope 2, one end of which is connected to the upper end of the first insertion rod 4; The second socket 202 is connected to the end of the steel wire rope 2 away from the first insertion rod 4, and the second insertion rod 5 passes through the second socket and is inserted into the ground.

[0022] In some embodiments, both the first connecting pipe 101 and the second connecting pipe 102 are square tubes. The inner side length of the cross-section of the first connecting pipe 101 is not greater than the diameter of the first insert rod 4. The square tube configuration ensures that adjacent support plates 1 are parallel and can be installed at a 90° angle according to usage requirements, such as... Figure 1 End of the guide groove.

[0023] In other embodiments, the first connecting pipe 101 and the second connecting pipe 102 are both round pipes, which can adjust the included angle between two adjacent support plates 1.

[0024] The inner edges of both ends of the first connecting tube 101 are chamfered; the inner edges of both ends of the second connecting tube 102 are chamfered. The chamfered structure facilitates the insertion of the first insertion rod.

[0025] The wire rope 2 is connected to the upper end of the first insertion rod 4 through the first socket tube 201. The inner diameter of the first socket tube 201 is not less than the diameter of the first insertion rod 4. A first connecting ring 20101 is fixed on the side wall of the first socket tube 201. One end of the wire rope 2 is connected to the first connecting ring 20101. The upper end of the first insertion rod 4 is located inside the first socket tube 201.

[0026] A second connecting ring 20201 is fixed on the side wall of the second socket tube 202, and the end of the wire rope 2 away from the first connecting ring 20101 is connected to the second connecting ring 20201. The end of the wire rope 2 is connected to the main body of the wire rope 2 through a rope clamp to form a ring, and the rings at both ends of the wire rope 2 are located inside the first connecting ring 20101 and the second connecting ring 20201, respectively.

[0027] The wire rope 2 is equipped with a tensioning assembly 3, which includes: a positive threaded screw 302, one end of which is fixedly provided with a connecting seat 30201, which is detachably connected to the second socket tube 202; a negative threaded screw 303, one end of which is fixedly provided with a connecting plate, which is connected to the third socket tube 304; an adjusting tube 301, one end of which has a positive internal thread and the other end has a negative internal thread, and both ends of the adjusting tube 301 are threadedly connected to the positive threaded screw 302 and the negative threaded screw 303 respectively; and a third insert rod 6, which penetrates the third socket tube 304 and is inserted into the ground.

[0028] A hinge plate 30301 is fixedly mounted on the connecting plate, and a hinge hole is formed on the hinge plate 30301. A hinge post 30401 is fixedly mounted on the side wall of the third socket tube 304. The hinge post 30401 is installed inside the hinge hole and is hinged to the hinge plate 30301. The hinge plate 30301 facilitates the adjustment of the angle of the tensioning assembly 3 and facilitates the installation of the tensioning assembly 3 on uneven ground.

[0029] A hook 30202 is fixedly provided on the connecting seat 30201, a hanging plate 20202 is fixedly provided on the outer wall of the second socket tube 202, and a hanging post 20203 is fixedly provided on the hanging plate 20202. The hook 30202 and the hanging post 20203 are detachably connected.

[0030] There are two hooks 30202. The distance between the two hooks 30202 matches the thickness of the scraper. The scraper is located between the two hooks 30202. The scraper limits the hooks 30202 and prevents them from detaching from the hanging post 20203, thus improving the stability during use.

[0031] The upper ends of the first insertion rod 4, the second insertion rod 5, and the third insertion rod 6 are respectively fixed with baffles 7. The baffles 7 have second insertion holes 701. The axis of the second insertion hole 701 is perpendicular to the axis of the first insertion rod 4. The second insertion hole 701 facilitates the insertion of a handle to pull out the insertion rod. The first socket tube 201 is located between the baffle 7 of the first insertion rod 4 and the second connecting tube 102.

[0032] The regulating tube 301 has a first insertion hole 30101. The axis of the first insertion hole 30101 is perpendicular to the axis of the regulating tube 301. The first insertion hole 30101 facilitates the insertion of a pry bar to rotate the regulating tube 301.

[0033] Work process: In some embodiments, the support plate 1 is attached to the inner wall of the guide groove, and adjacent support plates 1 are installed. The second connecting pipe 102 of the adjacent support plate 1 corresponds to the first connecting pipe 101 of the previous support plate 1. The first insert rod 4 is inserted through the first socket pipe 201, and then through the second connecting pipe 102 and the first connecting pipe 101 in sequence before being inserted into the bottom end of the guide groove to limit the lower end of the support plate 1. The hanging post 20203 of the second socket pipe 202 is connected to the hook 30202 of the tensioning assembly 3. The third insert rod 6 is inserted into the third socket pipe 304. The third insert rod 6 is inserted into the ground after passing through the third socket pipe 304. Then, the adjusting pipe 301 is rotated to tighten the steel wire rope 2 (the length of the tensioning assembly 3 is shortened to tighten the steel wire rope 2). Then, the second insert rod 5 is inserted into the second socket pipe 202. The second insert rod 5 is inserted into the ground after passing through the second socket pipe 202 to fix the steel wire rope 2, thereby fixing the upper end of the support plate 1. Then, the third insert rod 6 is pulled out and the tensioning assembly 3 is removed. By using the tensioning component 3, greater tension can be provided to adjust the position of the second socket tube 202, thus broadening the scope of application and ensuring the flatness between multiple support plates 1.

[0034] In other embodiments, the support plate 1 is attached to the inner wall of the guide groove, and the second connecting pipe 102 of the adjacent support plate 1 corresponds to the first connecting pipe 101 of the previous support plate 1. The first insert rod 4 is inserted through the first socket pipe 201, and then through the second connecting pipe 102 and the first connecting pipe 101 in sequence before being inserted into the bottom end of the guide groove to limit the lower end of the support plate 1. After tightening the steel wire rope 2, the second insert rod 5 is inserted into the second socket pipe 202. The second insert rod 5 is inserted through the second socket pipe 202 and then inserted into the ground to fix the steel wire rope 2, thereby fixing the upper end of the support plate 1.

[0035] When using it, steel plates can be laid on the wire rope 2, which not only increases the strength of the wire rope 2, but also facilitates the subsequent laying of the track of the TRD construction machine.

[0036] The first insert rod 4 fixes the lower end of the support plate 1, and the second insert rod 5, together with the wire rope 2, fixes the upper end of the support plate 1. There is no supporting structure between the two parallel inner walls of the guide groove support plates 1, which facilitates the movement of the cutting box in the TRD method, improves the construction efficiency, prevents the guide groove from collapsing, and ensures the construction progress.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
