The bracket 211 extends out of the sliding connection part 212, the volume of the extension support part 210 is increased, the extension support part 210 protects the excavation groove 140 during the process of prolonging the excavation of the excavation groove 140, and the condition that the excavation groove 140 collapses is reduced. After the construction method is used, the construction method adopts the steps of firstly opening the smaller excavating groove 140 and then prolonging, so that the condition that the excavating groove 140 collapses because the excavating groove 140 is directly opened is reduced. After the excavation groove 140 is extended to a desired length, the extendable extension member 220 is extended, and the outer wall of the bracket 211 is pressed against the excavation groove 140 by the extendable extension member 220, thereby increasing the resistance between the bracket 211 and the excavation groove 140, and further achieving the purpose of supporting the extension support member 210. Excavation and layering of the soil layer below the extension support member 210 are performed, the soil layer on the upper portion is supported by the fixed extension support member 210, the situation that the soil layer on the upper portion is prone to collapse during manual excavation is reduced, and the influence of the soil layer on the upper portion on investigation of the ice water accumulation layer 110 is further reduced.
