Embodiment 1

[0036] refer to Figure 1 to Figure 6 , a seam structure with anti-filtering function, including a seam assembly, the seam assembly includes an anti-filter part 1 and a connecting part 2, one side of the connecting part 2 is fixedly connected with a structural member 3 on one side, the The other side of the connecting part 2 is connected to one side of the reverse filter part 1, one side of the reverse filter part 1 is close to the structural member 3 on the one side, and the other side of the reverse filter part 1 is close to Lean on the other side structural member 4;

[0037] The reverse filter part 1 adopts a compressible and rebound reverse filter material, and fine pores are distributed on the reverse filter part. The relationship between the characteristic particle size of the protected soil is in line with the filter criterion, namely:

[0038] o 95 ≤Bd 85

[0039] In the formula, O 95 is the equivalent pore diameter of the reverse filter part, d 85 is the chara...

Embodiment 2

[0049] refer to Figure 1 to Figure 6 , a construction method of a seam structure, said construction method comprising the following steps:

[0050] (1) One end of the reverse filter part 1 is fixedly connected with the structural member 3 on one side through the connecting part 2;

[0051] The reverse filter part 1 adopts a compressible and rebound reverse filter material, and fine pores are distributed on the reverse filter part. The relationship between the characteristic particle size of the protected soil is in line with the filter criterion, namely:

[0052] o 95 ≤Bd 85

[0053] In the formula, O 95 is the equivalent pore diameter of the reverse filter part, d85 is the characteristic particle size of the protected soil, B is the coefficient, determined according to engineering experience, and takes 0.5~3;

[0054] (2) Install the one side structural member 3 fixed with the reverse filter part 1 in place, and then install the other side structural member 4, one side...

Abstract

A seam structure with a reversed filter function comprises a seam component which comprises a reversed filter portion and a connection portion. One side of the connection portion is fixedly connected with a structural part on one side, the other side of the connection portion is connected with one side of the reversed filter portion, one side of the reversed filter portion is closely attached to the structural part on one side, and the other side of the reversed filter portion is closely attached to a structural part on the other side. The reversed filter portion is made of compressible and rebounding reversed filter materials, tiny holes are distributed in the reversed filter portion, sizes of the tiny holes are larger than those of water molecules, and the relation between effective aperture sizes of the reversed filter portion and protected soil characteristic particle sizes is in accordance with reversed filter criteria. The invention further provides a seam structure construction method. According to the seam structure with the reversed filter function and the construction method, drainage and soil protection functions are combined, and costs are low.

Description

technical field [0001] The invention relates to the field of joint treatment between prefabricated structural parts, in particular to a joint structure and a construction method. Background technique [0002] Joint treatment needs to be considered between prefabricated structural parts such as prefabricated structural retaining walls, sheet pile walls, and small caisson groups in various civil engineering projects. If it is closed, neither water nor soil can flow through the gaps, or if no treatment is done, water can flow through the gaps, but soil flow is easy to occur. In general engineering, the importance of both drainage and soil protection functions is often overlooked. When some projects consider the need for this function, other engineering measures that are not cheap are often taken on both sides of the gap. Contents of the invention [0003] In order to overcome the shortcomings of existing joint treatment methods between prefabricated structural parts that can...
