[0019] Figure 2 It is the schematic diagram of the utility model embodiment two;

[0020] Figure 3 It is the A place enlarged view in the utility model Figure 2 . DETAILED DESCRIPTION

[0021] The technical scheme in the utility model embodiment will be clearly and completely described below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment.

[0022] As Figure 1As shown, a typical embodiment of the utility model provides a kind of tunnel engineering center drainage ditch construction device, including the side plate 1 for supporting the two side wall templates of tunnel water ditch, the bottom plate 2 connected between the bottom of two side plates 1 and the adjusting assembly connected between the opposite faces of two side plates 1, adjusting assembly is used to control the synchronous relative motion or opposite motion of two side plates 1.

[0023] Two side plates 1 are supported on the side surface of the two side wall templates of tunnel water ditch, and two side plates 1 are connected using bottom plate 2, so that a relatively stable state is formed between two side plates 1 and bottom plate 2, which can improve the stability of supporting the side wall template of tunnel water ditch. By setting adjusting assembly, when adjusting assembly makes two side plates 1 opposite motion, the template can be fixed on the tied steel bar through side plate 1, and at the same time, the deviation of template during concrete process is reduced. When adjusting assembly makes two side plates 1 relative motion, the pressure on the template can be removed, and the template removal operation is better adapted.

[0024] On this basis, bottom plate 2 and side plate 1 are detachably connected by bolts. When the device is taken out, if the whole cannot be directly taken out, the bolts between bottom plate 2 and side plate 1 can be removed, and then bottom plate 2 and side plate 1 are taken out in blocks.

[0025] Adjusting assembly includes middle adjusting component 3 connected between the middle position of opposite faces of two side plates 1 and lateral adjusting component 4 located in the lateral of middle adjusting component 3 in the length direction of side plate 1, middle adjusting component 3 includes middle silk sleeve 3.1 and middle screw rod 3.2 threadedly connected at both ends of middle silk sleeve 3.1, lateral adjusting component 4 includes lateral silk sleeve 4.1 and lateral screw rod 4.2 threadedly connected at both ends of lateral silk sleeve 4.1, and one end of middle screw rod 3.2 and lateral screw rod 4.2 towards side plate 1 is connected with side plate 1.

[0026] By rotating middle silk sleeve 3.1 and lateral silk sleeve 4.1, the size of the opening between two side plates 1 is adjusted by two middle screw rods 3.2 and two lateral screw rods 4.2, so that two side plates 1 can press the template or loosen the template.

[0027] On this basis, the outer side end of middle screw rod 3.2 is rotatably connected with middle connecting seat 5, the outer side end of lateral screw rod 4.2 is rotatably connected with lateral connecting seat 6, middle connecting seat 5 and lateral connecting seat 6 are fixed on side plate 1, and middle screw rod 3.2 and lateral connecting seat 6 are rotatably connected in vertical plane, and lateral screw rod 4.2 and lateral connecting seat 6 are rotatably connected in vertical plane. In the rotating process of middle silk sleeve 3.1 and lateral silk sleeve 4.1, middle connecting and lateral connecting seat 6 can prevent middle screw rod 3.2 and lateral screw rod 4.2 from rotating respectively.

[0028] As Figure 2 AndFigure 3 As shown in the second embodiment of the utility model, a strip-shaped slot 7 is formed in the lateral connecting seat 6, and a sliding rod 8 is arranged on the lateral screw rod 4.2 and is capable of moving in the strip-shaped slot 7. In this embodiment, the sliding rod 8 is capable of providing pressure to the template by abutting against the inner wall surface of the strip-shaped slot 7 near the template, thereby fixing the template.

[0029] When the middle adjusting component 3 is operated to increase the distance between the two side plates 1, the sliding rod 8 is capable of moving inward relative to the strip-shaped slot 7, so that the lateral adjusting component 4 can satisfy the process of increasing the distance between the two side plates 1 while maintaining the length unchanged. Therefore, in the actual operation process, the middle adjusting component 3 and the lateral adjusting component 4 do not need to be operated synchronously. After the middle adjusting component 3 is operated to increase the distance between the two side plates 1, the lateral adjusting component 4 can be operated to make the sliding rod 8 abut against the inner wall surface of the strip-shaped slot 7 near the template.

[0030] On this basis, a slot entrance 9 is formed in the side of the top end of the strip-shaped slot 7, which is used for the sliding rod 8 to enter the strip-shaped slot 7. The slot entrance 9 is used for the sliding rod 8 to move away from the strip-shaped slot 7, thereby realizing the function of disassembling the lateral adjusting component 4.

[0031] The width of the strip-shaped slot 7 is greater than the outer diameter of the sliding rod 8, so that the sliding rod 8 is capable of moving in the height direction in the strip-shaped slot 7. In this way, when the middle adjusting component 3 is operated to increase the distance between the two side plates 1, the strip-shaped slot 7 is capable of moving relative to the sliding rod 8 in the height direction, and the movement in the inner-outer direction is combined, thereby avoiding the influence of the sliding rod 8 on the strip-shaped slot 7 on the movement of the side plate 1.

[0032] On this basis, the top of the lateral connecting seat 6 is provided with a baffle 10 which can be inserted into the strip-shaped slot 7, and the distance between the baffle 10 and the inner wall surface of the outer side of the strip-shaped slot 7 is adapted to the outer diameter of the sliding rod 8. Specifically, after the distance between the two side plates 1 is increased by the middle adjusting component 3 and the sliding rod 8 is abutted against the inner wall of the strip-shaped slot 7 near the template by the lateral adjusting component 4, the baffle 10 is pushed down so that the baffle 10 abuts against the side of the sliding rod 8 away from the template. At this time, the baffle 10 cooperates with the inner wall surface of the strip-shaped slot 7 near the template to realize the clamping action on the sliding rod 8, so that the sliding rod 8 is capable of limiting the template in the inner-outer direction, thereby reducing the vibration deviation of the template in the concrete pouring process and improving the stability of the template.

[0033] Perforations 11 are formed in the middle sleeve 3.1 and the lateral sleeve 4.1. The perforations 11 are used for steel bars or iron rods to be inserted in the operation of the middle adjusting component 3 and the lateral adjusting component 4, so as to increase the force arm and make the rotation of the middle sleeve 3.1 and the lateral sleeve 4.1 more convenient.

[0034] Specifically, in the second embodiment, the stopper is arranged in a circular arc structure, a receiving groove is formed on the lateral connecting seat 6, the stopper is rotated into the receiving groove to move away from the groove cavity of the strip-shaped groove 7, and the stopper is rotated into the interior of the strip-shaped groove 7 to be finally sleeved on the side of the sliding rod 8 away from the formwork.

[0035] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
