Description

Technical Field

[0001] The utility model belongs to the technical field of hydropower and water conservancy project construction, and specifically relates to a two-cloth-one-membrane expansion joint construction device for anti-seepage of a plain reservoir basin. Background Art

[0002] Plain reservoirs can solve the problem of insufficient water diversion for agricultural irrigation during the dry season of rivers to a certain extent. As a supplementary water source, they provide water for agricultural drought resistance and irrigation, and promote agricultural production and income. In water supply projects, regulating reservoirs are designed along the line, most of which are plain reservoirs, and PE composite geomembrane is used for reservoir basin anti-seepage. In the design, in order to prevent the displacement of the geomembrane caused by the water pressure acting on the concrete of the reservoir panel after the reservoir is filled with water, resulting in the cracking of the geomembrane under the action of stress, the design adopts S-type expansion joints to ensure the expansion margin of the geomembrane. In traditional construction, the two cloths and one membrane on the dam slope are welded and then folded manually due to the slope and the newly added S-type expansion joints in the design. Since the concrete on the dam slope is staggered, the dam slope geomembrane cannot be welded normally when it is welded (connected with the previous strip) due to the influence of the expansion joint (if the expansion joint is welded first and then folded, the exposure time of the geomembrane will not meet the design requirements. If the expansion joint is folded first and then welded, it will not be welded and a dead fold will be formed). In addition, since the bottom of the dam slope is a tooth wall groove, the two cloths and one membrane will be close to the foundation surface during the laying process from bottom to top, forming a broken line when reaching the groove, resulting in the welding machine being unable to climb through when welding adjacent geomembrane strips, making the construction difficult; when manually adjusting the two cloths and one membrane, there is a problem of insufficient lap width and the inability to keep the weld edge flush due to the inability to adjust the two cloths and one membrane as a whole.

[0003] Therefore, it is necessary to propose a two-cloth-one-membrane expansion joint construction device for anti-seepage of plain reservoir basin to solve the problems of great difficulty, limited space and dead bend of expansion joint after welding in traditional construction.

[0030] like Figures 1 to 3 As shown, the utility model comprises a vehicle body 1, a plurality of wheels 2 arranged at the bottom of the vehicle body 1 and a plurality of support frames arranged at the top of the vehicle body 1, wherein the plurality of support frames are evenly arranged along the length direction of the vehicle body 1, the vehicle body 1 is a cubic frame, a conical vehicle head 3 is arranged at one end of the vehicle body 1, and a handle 8 is arranged at the other end of the vehicle body 1;

[0032] The transverse support 4 is arranged along the width direction of the vehicle body 1 , and both ends of the transverse support 4 extend to the outside of both sides of the vehicle body 1 respectively.

[0033] In actual use, by setting the vehicle body 1 as a cubic frame and arranging a plurality of wheels 2 at the bottom of the vehicle body 1, it is convenient to move the vehicle body into the groove, and support the two cloths and one membrane at the groove, so that a working space for personnel to enter and exit can be formed at the bottom of the two cloths and one membrane, thereby facilitating construction personnel to enter the interior of the vehicle body 1 and cooperate with personnel on the slope surface to complete the side welding of adjacent strips of the two cloths and one membrane, which can effectively improve the construction efficiency of the two cloths and one membrane expansion joint and reduce the construction difficulty of the two cloths and one membrane expansion joint.

[0034] It should be noted that by arranging a conical head 3 at one end of the vehicle body 1, the conical head 3 is guided in front of the vehicle body, thereby facilitating pushing the vehicle body 1 and inserting it into the groove at the bottom of the overlapping section of two cloths and one film of adjacent strips.

[0035] In the specific implementation, a plurality of support frames are arranged on the top of the vehicle body 1, and an arc-shaped support 5 is arranged so that the top of the support frame is arc-shaped, and then the overlapping section of the two cloths and one film of adjacent strips is lifted up by the support frame, so that the overlapping section of the two cloths and one film of adjacent strips forms an arc-shaped surface through which the welding machine can climb and weld, which avoids the problem of insufficient overlap width and inability to keep the weld edge flush due to the inability to adjust the two cloths and one film as a whole when manually adjusting the two cloths and one film, and ensures the smoothness of the weld of the two cloths and one film.

[0036] In this embodiment, the vehicle body 1 includes four longitudinal brackets 101 , and the four longitudinal brackets 101 are connected by a plurality of rectangular frames to form a cubic frame. The rectangular frame includes two transverse brackets 102 and two vertical brackets 103 .

[0037] In this embodiment, the transverse support 4 and the transverse bracket 102 are parallel to each other, and the longitudinal bracket 101 and the transverse bracket 102 are perpendicular to each other.

[0038] In actual use, the longitudinal bracket 101 and the transverse bracket 102 are perpendicular to the vertical bracket 103 .

[0039] In this embodiment, the conical front end 3 is a quadrangular pyramid frame formed by connecting four oblique rods 301 , and the free ends of the four oblique rods 301 are respectively connected to the ends of four longitudinal brackets 101 .

[0040] In actual use, one end of the four oblique rods 301 is welded at one point.

[0041] In this embodiment, a longitudinal support rod 9 for mounting a handle 8 is fixed in the middle of the transverse bracket 102 at the other upper end of the vehicle body 1 , and the handle 8 is fixed to the end of the longitudinal support rod 9 away from the vehicle body 1 .

[0043] In this embodiment, a diagonal brace 10 is connected between the longitudinal support rod 9 and the two vertical brackets 103 at the other end of the vehicle body 1 , one end of the diagonal brace 10 is fixed to the longitudinal support rod 9 , and the other end of the diagonal brace 10 is fixed to the vertical bracket 103 .

[0044] In this embodiment, the tops of two adjacent arc-shaped supports 5 are connected to each other via a longitudinal reinforcing rod 7 .

[0045] When the utility model is actually used, Figure 4 As shown, before the expansion joint is welded, the two cloths and one film are lifted up, the car body 1 is pushed into the overlapped part of the two cloths and one film in the groove, and placed at the bottom of the two cloths and one film. The support frame on the top of the car body 1 forms an arc surface through which the welding machine can climb and weld at the overlapped part of the adjacent two cloths and one film, which not only avoids the difficulty of manually adjusting the width of the overlapped section of the two cloths and one film, but also ensures the smoothness of the weld of the two cloths and one film; the two cloths and one film welding machine climbs and welds downward from the slope surface, and after passing through the top arc surface of the car body 1, the welding of the two cloths and one film is completed;

[0046] At this time, the vehicle body 1 supports the two cloths and one membrane in the groove, so that a working space is formed at the bottom of the two cloths and one membrane for personnel to enter and exit. The construction personnel enter the bottom of the two cloths and one membrane in the groove through the vehicle body 1, and cooperate with the personnel on the slope to perform the bending construction of the two cloths and one membrane expansion joint according to the form and size of the expansion joint shown in the drawing. Then, the closed-cell plastic plate at the expansion joint is placed and fixed in the designated position by gluing. After completion, sandbags are used for temporary pressure fixing to prevent the expansion joint and the closed-cell plastic plate from moving and deforming. After the expansion joint construction is completed, the vehicle body 1 is withdrawn, and the two cloths and one membrane are adjusted to be close to the groove base surface, and then the subsequent tooth wall, slope protection board casting and other processes are carried out.

[0047] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
