Description

Technical Field

[0001] The present invention relates to the technical field of the erection construction of bridge engineering beam slabs, and particularly relates to a method and device for sliding erection of precast beam slabs. Background Art

[0002] In the current method, there are few construction methods for the erection of beam slabs at the openings of highway bridge tunnels. The common and frequently used construction methods are as follows: installing slides and trolleys on the abutment and capping beam, and using a bridge erection machine to cooperate in the erection of beam slabs; or directly using an engineering crane for the erection of beam slabs.

[0003] However, in the existing technology methods, due to the large volume and heavy weight of precast beam slabs, with a general weight of over 100 tons, the stability and safety during the sliding process need to be improved.

[0004] The main problem faced by the method of using an engineering crane for erection is that it has high requirements for the construction site. When the construction site has steep mountain cliff sections or terrain restrictions, it is directly impossible to use an engineering crane to cooperate to complete the construction.

[0005] Obviously, in the existing technology, there is a lack of a method for erecting precast beam slabs to cope with small construction sites, such as the steep terrain restrictions at the connection of bridges and tunnels, and the influence restrictions of the open cut and tunnel clearance and width at the tunnel entrance. This makes it impossible for the bridge erection machine to directly complete the beam lifting and erection operations of the side beams, and the on-site terrain conditions also cannot meet the requirements for crane beam erection.

[0006] Obviously, for the above technical problems, there is an urgent need to propose a solution to cope with the beam slab erection method. Summary of the Invention

[0077] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. It should be noted that for the convenience of description in this application, the "left side" in the current view is taken as the "first end", the "right side" as the "second end", the "upper side" as the "first end", and the "lower side" as the "second end". The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0078] The present invention aims to solve the technical problem of the lack of a method for erecting precast beam slabs in the prior art that can cope with small construction sites, such as the limitations caused by the steep terrain at the junction of bridges and tunnels, the influence of the open cut at the tunnel entrance and the tunnel clearance and width. A method and device for sliding erection of precast beam slabs are provided.

[0079] The content of the present invention is actually based on the practical application of the WYTJ-04 section project of the Xinjiang Urumqi-Yecheng Highway Package PPP project undertaken by the applicant. The actual construction content reduces the influence of limited site at the tunnel entrance, effectively improves the beam slab erection efficiency, and reduces the beam erection cost. At the same time, this method has less damage to the ecological environment. The situation of the project actually undertaken by the present invention is that the terrain at the junction of bridges and tunnels is steep. Due to the influence of the open cut at the tunnel entrance and the tunnel clearance and width, the gantry crane cannot directly complete the beam lifting and erection operations for the side beams, and the on-site terrain conditions also cannot meet the requirements for crane beam erection;

[0080] To this end, the technical solution of the present invention is based on the construction method of erecting beam slabs by a bridge girder erecting machine. On this basis, a transverse sliding beam erecting device 100 is adopted to achieve the smooth erection of precast beam slabs 3 under limited topographic and in-cave site conditions. The transverse sliding beam erecting device 100 includes:

[0081] A transverse movement track 10, a transverse sliding plate 20, a limit plate 30, a reaction seat 40, a fixing pin 40a for use, a wire rope hoist 4, and a support rod 60. Specifically:

[0082] The transverse sliding plate 20 has a track on the transverse movement track 10 and is used to carry the beam slab 3;

[0083] The limit plate 30 is fixedly connected to the transverse movement track 10 and is used to limit the maximum movement distance of the transverse sliding plate 20; and

[0084] A support and chain system is used to provide partial support for the carried beam slab 3 and use the wire rope hoist 4 to tighten the beam slab 3, so that a hydraulic jack 50 of a reaction force pushing system uses the position of the reaction seat 40 fixed on the transverse movement track 10 as a support point to push the transverse sliding plate 20 to move a certain action distance.

[0085] In a specific embodiment, please refer to Figure 1 、 2 As shown, the main features of the method part are:

[0086] (1) The transverse sliding plate 20 and the reaction seat 40 are formed by welding steel plates and are placed on the pre-erected transverse movement track 10. The lower part of the transverse movement track 10 uses templates and steel plates as its support, and it is necessary to ensure flatness;

[0087] (2) The support and chain system belongs to a temporary support system and is used for beam slab transverse movement operations after installation;

[0088] Before transverse movement, it is necessary to first reinforce and support the beam slab with the wire rope hoist 4 and the support rod 60 to ensure the stability of the beam body;

[0089] The bottom of the hydraulic jack 50 is abutted against the reaction seat 40, and the top of the hydraulic jack 50 abuts against the pulley to exert force to push the pulley forward. Since the displacement of the beam movement is relatively long, the hydraulic jack 50 cannot reach the designated position at one time. It is necessary to move the reaction seat 40 towards the beam slab and fix it after each jacking, and then the hydraulic jack 50 abuts against it and pushes forward. Repeat the cycle until the beam slab reaches the designated position; since jacks are used to move the beam at both ends of the beam along the sliding tracks, it is necessary to ensure that the propulsion error of the jacks at both ends is less than 10 cm.

[0090] (3) After the precast beam and slab are horizontally moved to the designated position, they are supported by two 100t jacks at the bottom of the beam and slab, and the side wings can also be supported by jacks. After ensuring that the beam body is horizontally moved in place, the fixed chain hoist and steel pipe support are removed, the slide rail jack is depressurized, and the beam and slab are installed. The specific detailed method is to provide an erection method for a precast beam and slab sliding erection device, including the following steps:

[0091] Step S101, during the construction of the abutment 1, after embedding steel bars at the middle block 2a position of the adjacent side beam 2, the concrete is not poured temporarily, and a horizontal sliding beam erection device 100 is adopted;

[0092] Step S102, at 25 - 35 cm inside the abutment 1, a horizontal movement track 10 is installed and fixed, and one end of the horizontal movement track 10 is close to the middle block 2a;

[0093] Step S103, install a horizontal movement slide plate 20, a limit plate 30, and a reaction seat 40 on the horizontal movement track 10;

[0094] Adjust the position of the reaction seat 40 according to the maximum distance that the bridge erection machine 1a can move horizontally to ensure that the bridge erection machine 1a can place the beam and slab 3 on the horizontal movement slide plate 20;

[0095] After the position adjustment is completed, fix the reaction seat 40 and the limit plate 30 by using the fixing method of the pin 40a, and install an oil jack 50;

[0096] Step S104, transport the beam and slab 3 to the tail of the bridge erection machine 1a for beam feeding and beam erection operations;

[0097] Step S105, the bridge erection machine 1a carries the beam and slab 3 horizontally and places the two ends of the beam and slab 3 on the horizontal movement slide plate 20 of the horizontal sliding beam erection device 100;

[0098] Step S106, use the installation of the support rod 60 and the wire rope hoist 4 chain tightening connection method to fix the beam body of the beam and slab 3 to ensure the stability of the beam and slab 3 on the horizontal sliding beam erection device 100;

[0099] The on-site operators check and confirm the stability of the oil jack 50 and the beam and slab 3;

[0100] Step S107, when it is confirmed that the beam and slab 3 are stable on the horizontal sliding beam erection device 100, use the oil jack 50 to slowly push the beam and slab 3 carried by the horizontal movement slide plate 20 as a whole towards the target side;

[0101] Adjust the positions of the reaction seat 40 and the oil jack 50 towards the target side, repeat the above operations, and gradually slide the side beam of the beam and slab 3 to the designed position;

[0102] Step S108, after the side beam of the beam and slab 3 reaches the designed position;

[0103] Install at the bottom of the beam-slab 3: the first jack 1-1 and the second jack 2-2 with a specification of 100t.

[0104] Through the lifting actions of the first jack 1-1 and the second jack 2-2, the beam-slab 3 is disengaged from the transverse sliding plate 20 of the transverse sliding beam erection device 100, and then the transverse sliding beam erection device 100 is removed as a whole.

[0105] Step S109, use the first jack 1-1 and the second jack 2-2 to lower the beam.

[0106] After lowering the beam, install and arrange round log diagonal braces on the outside of the beam body, move the first jack 1-1 at the bottom plate position to the end cross diaphragm 5, and then remove the second jack 2-2; use the first jack 1-1 to ensure the stability of the side beam.

[0107] On the first hand, this technical solution can directly abandon the cooperation of engineering cranes, erect the beam-slab horizontally through the tunnel entrance, reduce the influence caused by the limited site at the entrance, greatly reduce the influence on the construction site for implementing this technical solution, and can significantly improve the construction efficiency. This method has less damage to the ecological environment and also has advantages in environmental protection, and can also greatly improve the erection efficiency of the beam-slab.

[0108] On the second hand, compared with the traditional beam erection construction method, the construction cost of this technical solution can be reduced, and the problem of erecting the side beam when the tail of the bridge erecting machine is restricted by the site and cannot be horizontally moved is overcome, and finally the erection cost of each beam is reduced.
