Embodiment Construction

[0029] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second" and so on in the embodiments of the present invention, the descriptions of "first", "second" and so on are only for descriptive purposes, and should not be interpreted as indicating or implying Its relative importance or implicitly indicates the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the meaning of "and / or" appearing in the whole text includes three parallel schemes, taking "A and / or B" as an example, ...

Abstract

The invention discloses a waterproof plate trolley. The waterproof plate trolley comprises a portal frame, a movable formwork and a laying trolley. An arc-shaped track is installed on the portal frame, the movable formwork is movably installed on the portal frame and used for defining a filling space with a primary supporting layer, and the filling space is used for being filled with a bonding material. The laying trolley is movably installed on the arc-shaped track and can lay a waterproof plate on the movable formwork so that the waterproof plate can be bonded to the primary supporting layerthrough the bonding material. The waterproof plate trolley can solve the technical problem that a waterproof plate is prone to distortion, stretching or tearing during secondary lining construction at present.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a waterproof board trolley. Background technique [0002] In the current secondary lining construction, since the construction is along the exposed surface of the surrounding rock, the primary support layer formed after the sprayed concrete will be uneven, and the waterproof board generally needs to leave a moderate margin when laying the primary support layer, but in practice After laying, it is still unavoidable that the waterproof board will be twisted, stretched or torn, resulting in water leakage during the operation of the tunnel. [0003] The above content is only used to assist in understanding the technical solution of the invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to propose a waterproof board trolley, aiming at solving the current technical p...
