Embodiment Construction

[0023] Such as figure 1 and figure 2 As shown, the three-cone pressure trough plate includes the middle drill pipe 3, the left drill pipe 5 and the right drill pipe 1. The lower end of the rod is a conical head, and the upper end has a connecting head, which can be connected to the static pressing equipment. The shape and size of the left drill rod 5 and the right drill rod 1 are the same, and they are both cylindrical. The left drill rod and the right drill rod Both ends are tapered, the diameter d of the left and right drill pipes is 30~40mm, and the height h is 400~600mm. The left drill rod 5 is connected with the middle drill rod 3 through the left wing plate 4, and the right drill rod 1 is connected with the middle drill rod 3 through the right wing plate 2. The equilateral trapezoidal steel plate with a cutting edge at the end has a thickness of T=10~30mm, and the angle between the trapezoidal hypotenuse and the bottom edge, which is the middle drill pipe, is α=60~70°...

Abstract

The invention discloses a tri-cone-head pressing grooving plate, which comprises a middle drill rod, a left drill rod and a right drill rod, wherein the left drill rod and the right drill rod are same in shape and size; the left drill rod is connected to the middle drill rod through a left wing plate; the right drill rod is connected to the middle drill rod through a right wing plate; the left wing plate and the right wing plate are same in shape and size; central lines of the middle drill rod, the left wing plate, the right wing plate, the left drill rod and the right drill rod are all in a same horizontal plane; the lower end of the middle drill rod is a cone head while the upper end is provided with a connecting head; and the two ends of the left drill rod and the right drill rod are both conical. The invention also discloses a grouting slot construction method by using the tri-cone-head pressing grooving plate. According to the construction method, continuous grouting slots can beconstructed in a soil body; a continuous, uniform, regular and ultrathin high polymer impervious wall is formed after the slots are grouted; and the construction method is characterized by convenience and quickness in construction, small disturbance to a dam, capability of forming continuous ultrathin grouting slots, and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage and reinforcement of infrastructure such as water conservancy, mines, and environmental protection, and specifically relates to a three-cone pressure grooved plate used for anti-seepage reinforcement of earth embankments, earth dams, tailings dams, and sewage interception dams. The invention relates to a construction method for grouting slot holes using three-cone heads to form slotted plates. Background technique [0002] Since the founding of New China, my country's water conservancy, mining, environmental protection and other infrastructure construction have achieved world-renowned achievements, which have played an important role in my country's economic development and social progress. In terms of water conservancy infrastructure construction, since the vast majority of water conservancy facilities in my country were built in the 1950s to 1970s, limited by the economic and technological ...
