Because it is inconvenient to directly use mobile machinery for excavation operations, most of the excavation is done manually, and there is no working surface to take slope operations. During excavation, the upper part of the trench is prone to landslides and collapses, resulting in slow progress in the construction of pipelines in the lanes, which is time-consuming and labor-intensive.

A supporting structure applied to a trench according to claim 3, characterized in that: The supporting assembly (1) further comprises: a first receiving member (13), a second receiving member (14) and a second extension member (15); the first receiving member (13) and the second receiving member (14) are respectively slidably connected to two sides of the supporting member (11); the second extension member (15) is arranged outside the first receiving member (13) and the second receiving member (14) and is capable of abutting against the supporting piles (4) on both sides.

7. A supporting structure applied to a trench according to claim 6, characterized in that: The pressing assembly (2) further comprises a positioning member (24), wherein the positioning member (23) is disposed through the supporting member (11) and is slidably matched with the ejection member (21), the first receiving member (13) and the second receiving member (14), so as to be in contact and positioned with the supporting piles (4) on both sides through the positioning member (24).

8. A supporting structure applied to a trench according to claim 7, characterized in that: The supporting assembly (1) further comprises: a locking member (16), wherein the locking member (16) is arranged on a side wall of the supporting member (11) and is connected to the positioning member (24), so that the first receiving member (13) and the second receiving member (14) are positioned on both sides of the supporting member (11) through the connection between the locking member (16) and the positioning member (24).

9. A supporting structure applied to a trench according to claim 8, characterized in that: The pressing assembly (2) further comprises: an extension piece (25) and a limiting piece (26); the extension piece (25) is movably arranged on a side wall of the positioning piece (24) and is connected and limited with the positioning piece (24) through the limiting piece (26), so that the degree of pressing of the positioning piece (24) against the supporting pile (4) can be increased through the extension piece (25).

10. A construction process for a supporting structure applied to a trench, used for a supporting structure applied to a trench as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Aligning the two sides of the top support assembly (1) with the side walls of the support piles (4) on both sides of the inside of the trench; Connecting the pressing component (2) to the supporting component (1); The extension components (3) on both sides of the supporting component (1) are squeezed by the pressing component (2); After the extension components (3) on both sides are pressed against and positioned against the side walls of the support piles (4) on both sides inside the trench, the construction process of the trench support structure is completed.
