Description

TECHNICAL FIELD

[0001] The utility model belongs to tunnel waterproof and drainage engineering technical field, provide simple structure, easy to prepare and effective guarantee the installation quality of one kind of tunnel inverted arch transverse drainage pipe positioning tool. BACKGROUND

[0002] In the tunnel waterproof and drainage system, the tunnel longitudinal drainage pipe is connected into the inverted arch transverse drainage pipe, and then the fissure water of surrounding rock is drained to the tunnel center ditch, and finally discharged outside the hole, forming the whole drainage system. The longitudinal drainage pipe connected with the transverse drainage pipe is designed with a tee joint. During the pouring of inverted arch concrete, the transverse drainage pipe often deviates from the designed position due to the extrusion of concrete, and the tee joint leaks.

[0003] In summary, the existing tunnel drainage pipe tool cannot guarantee the installation quality of the transverse drainage pipe, which further causes poor drainage. UTILITY MODEL CONTENT

[0004] Therefore, the utility model aims at providing a tunnel inverted arch transverse drainage pipe positioning tool to solve the technical problem that the existing tunnel drainage pipe tool cannot guarantee the installation quality of the transverse drainage pipe.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] The utility model provides a tunnel inverted arch transverse drainage pipe positioning tool, which comprises a fixed rod, at least two limiting rings for accommodating the transverse drainage pipe which are integrally welded with the fixed rod, and a limiting channel formed in the inner cavity between the limiting rings.

[0007] To ensure the stability of the transverse drainage pipe in the limiting channel, in the above-mentioned scheme, further, the limiting rings are three, and the three limiting rings are equidistantly arranged on the outer wall of the axial direction of the fixed rod.

[0008] To provide a welding operation space for workers and avoid the positioning interference caused by the limiting rings when the workers weld the fixed rod on the inverted arch longitudinal main reinforcement, in the above-mentioned scheme, further, the two limiting rings at the outermost end have a certain distance from the end of the fixed rod, so that the fixed rod has two welding sections.

[0009] The utility model has the advantages of:

[0010] (1) simple structure, easy to process, low cost, simple to use, easy to prepare.

[0011] (2) the tool can effectively fix the transverse drainage pipe, avoid the extrusion of the transverse drainage pipe caused by pouring concrete, and effectively guarantee the installation quality of the transverse drainage pipe.

[0012] Other advantages, objects, and features of the present application will be better understood from the following detailed description when considered in connection with the accompanying drawings. Implementation wherein BRIEF DESCRIPTION OF DRAWINGS

[0013] In order to make the purpose, technical scheme and advantages of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the drawings, in which:

[0014] Fig. 1 is a structural schematic view of the present application;

[0015] Fig. 2 is a structural schematic view of the present application in the side view direction;

[0016] Reference signs: 1, fixed rod; 2, limiting ring; 3, yielding welding section. DETAILED DESCRIPTION

[0017] The present application will be further described below in conjunction with specific embodiments. Among them, the drawings are only used for illustrative description, and the representation is only a schematic diagram, not a physical diagram, and cannot be understood as a limitation on the present patent; in order to better illustrate the embodiments of the present application, some components in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted. The drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and the following embodiments and the features in the embodiments can be combined with each other without conflict.

[0018] In addition, the present application can refer to the same reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0019] As Figs. 1-2 shown, the present application refers to a kind of tunnel inverted arch transverse drain pipe positioning tool, wherein: including a fixed rod 1, at least two limiting rings 2 for accommodating transverse drain pipe welded with fixed rod 1 as a whole, the inner cavity between limiting ring 2 forms limiting channel.

[0020] In order to ensure the stability of transverse drain pipe in limiting channel, in the above scheme, further: the limiting ring 2 is three, and the three limiting rings 2 are equidistantly arranged on the outer wall of the axial direction of fixed rod 1.

[0021] In order to provide a welding operation space for the worker, avoid the positioning interference caused by the limiting ring 2 to the worker when welding the fixing rod 1 on the inverted arch longitudinal main reinforcement, in the above scheme, further: the two limiting rings 2 located at the outermost end have a certain distance between the end of the fixing rod 1, so that the fixing rod 1 has two welding sections 3.

[0022] In the above embodiment, all components are market sales products.

[0023] The use process of the structure in the above scheme is: when installing the transverse drainage pipe, first pass the transverse drainage pipe through the limiting ring 2, then weld the welding sections 3 of the fixing rod 1 on the inverted arch longitudinal main reinforcement after the transverse drainage pipe and the longitudinal drainage pipe are connected firmly through the tee joint, check the welding and firmness, and ensure that it can not be loose. When pouring the inverted arch concrete, the positioning tool is in action, the transverse drainage pipe will not be offset due to the extrusion of the concrete, and the installation quality is effectively guaranteed.

[0024] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
