Description

TECHNICAL FIELD

[0001] The utility model relates to two lining trolley technical field especially relates to a tunnel two lining trolley anti -cracking V type rubber strip adjustment in position device. BACKGROUND

[0002] In the project construction, in order to prevent concrete to drop, at every mould concrete construction joint position, intentionally leave a triangle groove, the method for constructing this triangle groove is:

[0003] 1, set a half triangle steel mould in the trolley front direction plug position, when finishing concrete, leave a half triangle groove in front concrete.

[0004] 2, install a triangle rubber strip in the half triangle groove position, generally use glue, or anchor the triangle strip on concrete, after the triangle rubber strip is fixed on concrete, two lining trolley walks over, and goes up, and the formwork is in position, when finishing concrete rear position, form a complete triangle groove, this reaches the construction requirement.

[0005] 3, but because the triangle rubber strip is not fixed, and the glue is not good to stick, if using anchor bolt to anchor on the wall, after multiple times, the rubber strip is destroyed, whether gluing or anchoring, is easy to drop.

[0006] 4, based on the above difficult project construction, often adopts the manual groove method, does not use the above method, directly uses cutting machine to cut concrete into the appearance required by the project acceptance, but this method is time -consuming and labor -intensive. UTILITY MODEL CONTENTS

[0007] The utility model aims at solving the problems of the triangle rubber strip falling easily and being time -consuming and labor -intensive in the prior art, and provides a tunnel two lining trolley anti -cracking V type rubber strip adjustment in position device.

[0008] In order to achieve the above object, the utility model adopts the following technical scheme:

[0009] A tunnel two lining trolley anti -cracking V type rubber strip adjustment in position device, including trolley main part, the top of trolley main part is provided with a plurality of top mould support rods, the both sides of trolley main part are provided with a plurality of side mould support rods, the top of trolley main part one side is provided with has been poured concrete, the top of trolley main part is provided with trolley faceplate, the trolley faceplate includes side mould formwork and top mould formwork, the top mould formwork is set up at the top of a plurality of top mould support rods, the side mould formwork is set up at one end of a plurality of side mould support rods, the top of trolley faceplate is provided with the concrete to be poured, one side of trolley faceplate is provided with mould assembly for the concrete to be poured pouring;

[0010] The bottom of the casted concrete and the to-be-cast concrete is provided with a triangular groove, and the other side of the trolley panel is provided with a blocking assembly for blocking the triangular groove.

[0011] In a possible design, the mold assembly comprises an ear plate fixedly connected to one side of the trolley panel, an inner part of the ear plate is fixedly connected with a rotating shaft, an outer wall of the rotating shaft is rotationally connected with a rotating support frame, one end of the rotating support frame is fixedly connected with a side edge mold plate, and the side edge mold plate is matched with one side of the to-be-cast concrete.

[0012] In a possible design, the mold assembly further comprises a V-shaped groove mold plate fixedly connected to the bottom of one side of the side edge mold plate.

[0013] In a possible design, the blocking assembly comprises a rear end lap joint mold plate fixedly connected to one side of the trolley panel, the top of the rear end lap joint mold plate is provided with a rubber pad, and the top of the rubber pad is provided with a V-shaped rubber strip main body.

[0014] In a possible design, the bottom of the V-shaped rubber strip main body is bonded with a plurality of handles, the handle comprises a supporting part and a holding part, the holding part is integrally formed at one end of the supporting part, and the supporting part is bonded with the V-shaped rubber strip main body.

[0015] In a possible design, a bending part is arranged between the supporting part and the holding part, and a holding hole is arranged on the holding part.

[0016] In a possible design, a plurality of casting holes are arranged on the side mold plate and the top mold plate.

[0017] In the present application, a handle is bonded at a certain distance on the triangular rubber strip, the V-shaped rubber strip main body with the handle is placed at the rear end of the trolley before the trolley is in place, and then the trolley is pushed up to a gap of only 10mm or less, and the position of the rubber strip is observed by artificial observation, if the position is not appropriate, the handle position is adjusted to adjust the V-shaped rubber strip main body to the appropriate position. All positions of a circle are adjusted in this way. When all positions are adjusted, the trolley is tightly pushed to the rear end, the secondary lining concrete is constructed, the method is simple, and the difficulty of the construction site is solved.

[0018] If there is no such method, the triangular rubber strip is too small, the gap between the secondary lining trolley and the old concrete is small, and the operation cannot be performed, the triangular rubber strip is placed in a fixed position in advance, the secondary lining trolley is often not accurately overlapped by 100mm, the rear end lap joint position is changed due to mileage reasons, tunnel longitudinal slope reasons, or tunnel curve reasons, and therefore accurate adjustment needs to be performed at each position.

[0019] The handle material needs to be light, thin, hard, and can be bonded with the triangular rubber strip by using universal glue.

[0020] Beneficial effects: precise adjustment and positioning

[0021] By pasting the handle at intervals on the triangular rubber strip and adjusting the position before the second lining trolley is in place, it can be ensured that the main body of the V-shaped rubber strip can be accurately aligned with the required position at each position. This method solves the problem of difficult operation in a small space, especially in the case where the gap between the second lining trolley and the old concrete is small, and can ensure the accuracy of the rear overlap.

[0022] Strong adaptability:

[0023] Due to the mileage, longitudinal slope or curve reasons in tunnel construction, the rear overlap position may change. The present application can be accurately adjusted at each position through manual observation and handle position adjustment, thereby adapting to different construction environments and conditions.

[0024] Simplified construction method:

[0025] Compared with the traditional method, the present application provides a simpler and more effective construction method. Only the V-shaped rubber strip body with handle needs to be placed at the rear end of the trolley, and the handle position is adjusted for accurate adjustment, and then the second lining concrete can be constructed, which greatly simplifies the construction steps and processes.

[0026] Improve construction efficiency:

[0027] Through accurate adjustment and quick positioning, the present application can reduce the time and labor cost in the construction process, and improve the construction efficiency. At the same time, since the method is simple and easy to understand, the skill level requirement of the construction personnel is also reduced.

[0028] Reasonable selection of materials:

[0029] The selection of handle material meets the construction requirements, which is light, thin, has hardness, and can be bonded with the triangular rubber strip by universal adhesive. This material selection not only ensures the convenience and reliability of construction, but also improves the stability and durability of the entire system. BRIEF DESCRIPTION OF DRAWINGS
