Problems solved by technology

[0004] The DJ180 bridge erecting machine is suitable for the subgrade length at the tunnel entrance not less than 23.5m. However, during tunnel construction, the distance between the abutment and the tunnel entrance is short. If the construction is carried out directly, the normal construction conditions cannot guarantee to meet the requirements for erecting beams at the tunnel entrance; And it is impossible to estimate the impact of collision, which will cause trouble to the construction, increase the difficulty of construction, poor safety and operability

Embodiment 2

[0078] Same as embodiment 1 scheme, specific

[0079] 1. To solve the problem that the bridge erecting machine passes through the tunnel smoothly, the problem that needs to be solved is to compress the height of the bridge erecting machine so that the components of the bridge erecting machine do not collide with the tunnel when passing through the tunnel. For this reason, the bridge erecting machine passes through the tunnel. Prepare for the following:

[0080] 1) Install the transfer bracket of the bridge erecting machine on the beam transporter, and use the beam transporter to carry the bridge erection machine through the tunnel. The height of the beam transporter is 1.1 meters, and the height of the bogie is 2.64 meters;

[0081] 2) At the place where the beam transport vehicle runs on the bridge-erecting machine, the transverse load center of the front vehicle is 14.5 meters away from the front end of the arm of the bridge-erecting machine, and the transverse load center o...

Embodiment 3

[0099] Same as embodiment 1 scheme

[0100] 1. In order to ensure the quality:

[0101] 1. Feeding beam, binding beam, hanging beam

[0102] (1) When tying beams, iron tiles should be installed, the iron tiles on both sides should be aligned, the steel wire rope should be in the middle of the iron tiles, and check whether there is mutual pressure on the steel wire ropes and whether they are lapped.

[0103] (2) When tying the beam, the jack rope should be kept vertical and not hung obliquely. It is forbidden to forcefully push the hook vertically or horizontally to hang the jack rope in place, so as to avoid violent swing during lifting, or cause the steel wire rope to slide suddenly and cut off the wire rope, causing crushing injuries. beam body.

[0104] (3) Before any beam lifting operation, a trial lifting is required. That is to say, after the beam is tied up, the hoist should be braked for 2-3 times, and then the beam should be lifted a little to check whether the ste...

Embodiment 4

[0152] The same as the method in Embodiment 1, the applied engineering example is:

[0153] In the JQJXZQ-4 standard laying project of the newly-built Jiujingqu Railway, the amount of bridge engineering in this area is relatively large, and there are many tunnels. China Railway Sixth Bureau has no construction experience in short-distance beam erection at the tunnel entrance, so BIM technology is used to erect beams at the entrance and exit of the tunnel. The working conditions were simulated, the construction method of the beam erection was optimized, and the beam erection at the entrance and exit of the tunnel in the JQJXZQ-4 standard laying frame of the newly-built Jiujingqu Railway was completed safely and on time. The use of BIM construction technology to guide the beam erection construction at the entrance and exit of the tunnel has received unanimous praise from Nanchang Railway Bureau and the owner.

Abstract

The invention discloses a tunnel portal beam erection simulated construction method through a DJ180 bridge erection machine by using a BIM (Building Information Modeling) technology and relates to the technical field of tunnel construction. The method comprises the following steps: () modeling in BIM; (2) simulating the construction process; (3) determining an optimal construction scheme; and (4) producing a construction video. According to the simulated construction scheme, the overall construction scheme is optimized, the tunnel portal beam erection requirement is met, and safe and smooth beam erection construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel. Background technique [0002] BIM construction technology refers to building information modeling (Building Information Modeling) or building information management (Building Information Management). have real information. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. [0003] DJ180 bridge erecting machine is used for erecting prestressed reinforced concrete beams with a span of 40 meters or less for highway bridges and 32 meters or less for railway beams, and laying 25m of railway rail rows. The machine is a single-arm simple support type, and the maximum span of the beam that can be erected is 40 meters. It can realize the full-width mechanical lateral movement of the beam, and the beam can be dropped in place at one time. In th...
