[0024] As Figures 1-8 shown, the fixed structure system suitable for fixing the anti-seepage membrane on the structure, comprising fixed member, compression strip 4 and compression member; in the scheme, mainly acting on ecological wetland and various efficient wetlands.

[0025] As Figure 1 shown, the wall body 1 of ecological wetland and various efficient wetlands can be the original structure or the newly-built ecological wetland wall body. The newly-built ecological wetland wall body generally utilizes brick masonry or concrete and is constructed according to the designed height and thickness. According to different requirements, the thickness of brick masonry is generally 26 cm, the thickness of concrete wall body is generally 30 cm, and there is also the wall body 1 constructed by rubble, and the thickness is indefinite. After the completion of the ecological wetland civil construction, the civil construction is accepted, and after the acceptance, the anti-seepage membrane 2 is laid on the ecological wetland to prevent the water in the wetland from seeping out. The filter material is arranged on the anti-seepage membrane 2, that is, the anti-seepage membrane 2 is arranged between the ecological wetland and the filter material.

[0026] The filter material is arranged in the ecological wetland, the laying height of the filter material is lower than the maximum height of the wetland, and the laying height of the anti-seepage membrane 2 is higher than the height of the filter material.

[0027] The thickness of the impermeable membrane 2 is set to 1-2 mm, and the structure is two cloth and one membrane. The impermeable membrane 2 is laid along the ecological wetland wall, and needs to be closely attached to the civil structure of the ecological wetland during laying. A certain amount of excess is reserved during laying of the impermeable membrane 2 to prevent tearing and damage of the impermeable membrane 2 after the filter material is filled. After the impermeable membrane 2 is laid, according to the process requirements, in order to facilitate fixation, reduce the amount of impermeable membrane 2 folding, and also to prevent elastic deformation, the highest position of the impermeable membrane 2 and the height at which the impermeable membrane 2 needs to be fixed are determined, and obvious marks are made, and a pressing strip 4 is arranged at the mark to extrude the impermeable membrane 2. The impermeable membrane 2 itself is a flexible material, and the characteristics of the flexible material are that it is not easy to fix when folding, and is easy to produce elastic deformation. The setting of the pressing strip 4 can prevent the edge of the impermeable membrane 2 from being elastically deformed due to bending, directly fix the top edge of the impermeable membrane 2 to the ecological filter bed, and avoid folding of the impermeable membrane 2. Not only can it save materials, but it can also directly avoid the possibility of causing the flexible material to produce a bulge shape.

[0028] As shown in Figures 2-6 The pressing strip 4 is set as a stainless steel pressing strip, and the width and thickness of the stainless steel pressing strip are set according to needs. When the width is set to 3-5 cm and the thickness is set to 1-5 mm, it is the most economical, and at the same time, it can realize the fixation of the impermeable membrane 2; the width and thickness of the stainless steel pressing strip need to be set to resist the force of elastic deformation of the edge of the impermeable membrane 2 due to bending. In this scheme, the ecological wetland is 40 meters long, 25 meters wide, and 1.5 meters high, and the width of the stainless steel pressing strip used is 3.5 cm, and the thickness is set to 1.5 mm.

[0029] In order to make the extrusion force of the stainless steel pressing strip on the bulge reach the maximum, a fixing part is arranged to set the stainless steel pressing strip on the wall 1 of the ecological wetland, and in the process of fixing the stainless steel pressing strip on the wall 1, the impermeable membrane 2 is also tightly fixed between the wall 1 and the stainless steel pressing strip, which better avoids the generation of the bulge.

[0030] The fixing part can be set as any structure that can fix the stainless steel pressing strip on the wall 1. In this scheme, the fixing part is set as a fixing bolt 5, and further, the fixing bolt 5 is set as an expansion bolt.

[0031] The fixing bolt 5 is arranged on the stainless steel pressing strip, but in order to ensure that the stainless steel pressing strip has enough extrusion force on the impermeable membrane 2 and ensures that the impermeable membrane 2 is in close contact with the ecological wetland wall 1, a plurality of fixing bolts 5 are arranged on the stainless steel pressing strip, so that a plurality of bolt holes are formed on the stainless steel pressing strip, the number of the bolt holes is equal to the number of the fixing bolts 5, and the extraneous water is prevented from penetrating into the excess bolt holes. The bolt hole is first formed to facilitate installation. When the number of the fixing bolts 5 is arranged, the least number of the fixing bolts 5 is considered to generate enough extrusion force on the stainless steel pressing strip. The fixing bolt 5 is arranged on the stainless steel pressing strip, so that the stainless steel pressing strip has enough extrusion force on the impermeable membrane 2 at the end point where the fixing bolt 5 is arranged. In the actual use process, if the fixing bolt 5 is arranged at the two end points of the whole stainless steel pressing strip arranged at the edge of the ecological filter bed, only the two end points where the fixing bolt 5 is arranged can have enough extrusion force. If it is required to ensure that the stainless steel pressing strip has enough extrusion force at any point, a plurality of fixing bolts 5 need to be arranged closely on the stainless steel pressing strip to obtain enough extrusion force. In the present scheme, when the fixing bolts 5 are uniformly arranged on the stainless steel pressing strip, the distance between the adjacent two fixing bolts 5 is 50-80 cm, so that the extrusion of the pressing strip 4 on the impermeable membrane 2 can be ensured in the initial use.

[0032] In order to ensure the connection between the impermeable membrane 2 and the wall 1, holes are punched on the wall 1 of the ecological wetland according to the position and size of the fixing bolt 5, and the installation hole is drilled on the wall 1 of the ecological wetland by using an electric tool. The size of the installation hole is 14 mm in diameter and 60-70 mm in depth, the number of the installation hole is the same as that of the fixing bolt 5, and the position of the installation hole is arranged one by one corresponding to the position of the bolt hole. The inner wall of the installation hole is smooth without cracks, the connection of the fixing bolt 5 is reliable, the hole is cleaned, and the opening direction is perpendicular to the structure of the wall 1. In the present scheme, the distance between the two installation holes is the same as the distance between the two adjacent fixing bolts 5, which is 50-80 cm, and the centers of all the installation holes are on the same horizontal plane, so that the extrusion force on the bulge is uniform.

[0033] The fixing bolt 5 is arranged on the stainless steel pressing strip, and the stainless steel pressing strip transmits the extrusion force to the impermeable membrane 2. Since the fixing bolt 5 is arranged vertically to the wall 1, the extrusion force on the impermeable membrane 2 is perpendicular to the wall 1 and towards the wall 1. When the bulge of the impermeable membrane 2 is generated, the force of the bulge is perpendicular to the stainless steel pressing strip and towards the stainless steel pressing strip. At this time, the extrusion force and the force of the bulge are offset, so that the generation of the bulge is avoided.

[0034] When experiencing wind and sun, rain and water erosion, only set the stainless steel bar and fixed bolt 5 to prevent seepage membrane 2 fixed, still can occur edge of the seepage membrane 2 slip down, prevent seepage membrane 2 and ecological filter bed between air layer, form the problem of bulge, thus, for better guarantee prevent seepage membrane 2 and ecological wetland wall 1 closely connected, between the stainless steel bar and prevent seepage membrane 2 set pressure piece, the pressure piece can be set to rubber etc. Flexible material, can also be set to elastic plate etc. Elastic material.

[0035] The pressure piece is set to rubber strip 32, the size of the rubber strip 32 is equal to or greater than the size of the stainless steel bar, in this scheme, the size of the rubber strip 32 is consistent with the size of the stainless steel bar, the width is 3-5 cm, the thickness is 2-3 cm. The rubber strip 32 is a flexible material, which can more area to make stainless steel bar and prevent seepage membrane 2 extrusion, so that the prevent seepage membrane 2 more closely with ecological wetland wall 1 contact, at the same time, the rubber strip 32 is set to water swelling water stop, if there is water through the stainless steel bar into, the water swelling water stop expands when water, better block the position of the opening, further avoid the occurrence of water seepage. For better fixing water swelling water stop, the water swelling water stop is provided with rubber mounting hole, the number of rubber mounting hole is same with the number of fixed bolt 5, the setting position of rubber mounting hole is same with the setting position of fixed bolt 5, the interval between two adjacent rubber mounting hole is 50-80 cm.

[0036] The pressure piece is set to elastic plate 31, the elastic plate 31 is arranged in arch shape, the elastic plate 31 includes two movable ends and a convex end, when the two movable ends are close to each other, the elastic plate 31 is arched in the middle to form the convex end, the two movable ends of the elastic plate 31 are connected with the stainless steel plate, and the convex end formed after the elastic plate 31 is arched is in contact with the prevent seepage membrane 2. Further, the two movable ends of the elastic plate 31 are fixed with the stainless steel plate, and the fixing mode includes but is not limited to welding and bonding. In this scheme, the two movable ends of the elastic plate 31 are welded with the stainless steel plate. The elastic plate 31 can be provided with only one, and the two movable ends of the elastic plate 31 are connected with the stainless steel bar. The elastic plate 31 can also be provided with a plurality of elastic plates 31, and the plurality of elastic plates 31 are connected with the stainless steel plate. The plurality of elastic plates 31 are sequentially arranged along the length direction of the stainless steel plate, and the end portions of two adjacent elastic plates 31 can be in contact or not in contact. The contact arrangement can make the contact surface between the elastic plate 31 and the prevent seepage membrane 2 larger, and the prevent seepage membrane 2 is more closely in contact with the wall 1 of the ecological filter bed. The plurality of elastic plates 31 can be welded on the stainless steel plate separately, or the end portions of two adjacent elastic plates 31 can be connected together and then welded on the stainless steel plate together, so as to ensure the extrusion of the prevent seepage membrane 2 and make the prevent seepage membrane 2 more closely in contact with the ecological wetland wall 1.

[0037] When the pressing member is set as the waterproof rubber strip 32, the waterproof rubber strip 32 needs to be pressed by external pressure to make the impermeable membrane 2 tightly contact with the ecological filter bed wall 1, thus, more fixing bolts 5 are needed to press the impermeable membrane 2 in most area towards the ecological filter bed, and meanwhile, more bolt holes are set, which is easy to enter water, and the waterproof rubber strip 32 can absorb water to expand, thus avoiding water seepage.

[0038] As shown in Figure 7 , Figure 8 When the pressing member is set as the elastic plate 31, only one fixing bolt 5 is set beside the elastic plate 31, and when the fixing bolt 5 is fastened, an extrusion force is generated to the elastic plate 31 in a certain range, so that the elastic plate 31 is deformed, thus the area of the elastic plate 31 extruding the impermeable membrane 2 is increased, and most area of the impermeable membrane 2 covered by the stainless steel pressing strip is pressed on the wall 1 of the ecological filter bed, thus ensuring the tight contact between the impermeable membrane 2 and the wall 1 of the ecological filter bed. However, the extrusion force generated by one bolt is limited, thus, in order to ensure the extrusion force on the impermeable membrane 2, one fixing bolt 5 is set in 1m range. The fixing bolts 5 used when the pressing member is set as the elastic plate 31 are less than the fixing bolts 5 used when the pressing member is set as the waterproof rubber strip 32, thus the number of holes is obviously reduced, and water seepage is further prevented.

[0039] When the stainless steel pressing strip extrudes the elastic plate 31, the corresponding projection length of the elastic plate 31 is less than the length between two screw holes, because the corresponding arc of the elastic plate 31 will be enlarged with extrusion, thus the projection length is also increased, and the tight contact between the impermeable membrane 2 and the ecological filter bed can be judged by observing the projection length of the elastic plate 31, when the projection length is equal to the length between two screw holes, the extrusion cannot be further performed, thus it is indicated that the tight contact is achieved.

[0040] Holes are opened on the stainless steel pressing strip and the pressing member, and water is easy to enter the holes, when the pressing member is set as the elastic plate 31, in order to prevent the water in the ecological filter bed from seeping into the hole through the hole position, a waterproof structure layer 6 is set at the connection between the structure and the wall 1 after the installation of the above structure, and when the pressing member is set as the waterproof rubber strip 32, the waterproof rubber strip 32 can absorb water to expand, thus having a certain waterproof effect, thus the waterproof structure layer 6 can not be set, but in order to better avoid water seepage, the waterproof structure layer 6 can be set at the connection between the structure and the wall 1. The waterproof structure layer 6 is set to 2mm, and a circular arc chamfer treatment is set, and the angle is set to 45°, in the present scheme, the waterproof structure layer 6 is set as a building waterproof structure glue.

[0041] After the laying of the impermeable membrane 2 is completed, the highest part of the impermeable membrane 2 is marked, a stainless steel pressing strip is prepared, a plurality of bolt holes are formed on the stainless steel pressing strip according to the number of the set fixing bolts 5, the interval between two adjacent bolt holes is 50-80 cm, and the centers of the plurality of bolt holes are located on the same horizontal line; a waterproof rubber strip 32 with a size comparable to that of the stainless steel pressing strip is prepared, a plurality of rubber mounting holes are formed on the waterproof rubber strip 32, the number of the rubber mounting holes is the same as that of the fixing bolts 5, and the interval between two adjacent rubber mounting holes is 50-80 cm; a plurality of mounting holes are formed on the wall body 1 at the corresponding positions, the number of the mounting holes is the same as that of the fixing bolts 5, and the interval between two adjacent mounting holes is 50-80 cm; when the stainless steel pressing strip is placed at the corresponding position of the wall body 1, the mounting holes, the rubber mounting holes and the bolt holes correspond to each other one by one.

[0042] Then the waterproof rubber strip 32 is placed on the impermeable membrane 2, the stainless steel pressing strip is arranged on the waterproof rubber strip 32, the fixing bolts 5 pass through the bolt holes, the rubber mounting holes and the mounting holes in sequence, and the waterproof rubber strip 32 and the stainless steel pressing strip are fastened on the wall body 1, and at the same time, the positions where the impermeable membrane 2 may be bulged are extruded to prevent the bulging.
