Embodiment Construction

[0065] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] Such as Figure 1 to Figure 9 As shown, the present invention is a three-pipe method culvert jacking construction device, which is composed of three parts, namely the initial jacking part, the execution part and the power transmission part. Among them, the initial pushing part is composed of the push plate 601, the hydraulic cylinder 602 and the concrete back seat 603 to form the initial pushing device 6; the execution part is composed of the prefabricated lining 701 and the rubber ring 702 to form the lining rubber ring 7; the power transmission part is composed of the air compressor 5 , Control valve 4, a pipe 1, b pipe 2 and c pipe 3.

[0067] In the initial pushing part, one end of the hydraulic cylinder 602 is connected to the concrete back seat 603, and the other end is connected to the push plate 601. The forward and backward m...

Abstract

The invention discloses a three-pipe culvert incremental launching construction device and method. The construction device comprises an initial incremental launching equipment air compressor, a control valve and a plurality of sets of lining rubber rings; and the construction method comprises an initial incremental launching stage and a three-pipe incremental launching stage. During the initial incremental launching stage, a lining of the culvert entrance section is incremental launched for a distance by a hydraulic cylinder and rubber rings and enters into the three-pipe incremental launching stage; and after entering into the three-pipe incremental launching stage, every three linings are divided into a group and alternately move forwards under the pressure of the recirculate selected three tubes. According to the three-pipe method culvert incremental launching construction device and construction method, the obstruction of the culvert length to a traditional construction method is overcame, the movement of the hydraulic cylinder caused by a traditional incremental launching construction method is avoided, the culvert incremental launching construction is promoted to develop in the direction of mechanization, and the input of the linings is continuous. Therefore, the influence of the construction method on the culvert, the uplink rail of culvert and the road is greatly reduced.

Description

[0001] Technical field: [0002] The invention belongs to the field of tunnel construction, and in particular relates to a three-pipe method culvert jacking construction device and construction method. [0003] Background technique: [0004] With the development of highway transportation, there are more and more examples of roads and sidewalks passing under roads and railway lines, and the problems faced by culvert engineering are becoming more and more obvious. For example, the length of culverts has become longer, and construction can be carried out without affecting the upstream traffic line. wait. At present, the construction of culverts mainly relies on the method of hydraulic cylinder jacking. Practice shows that this method has the following disadvantages: [0005] 1. Due to the limited stretching length of the hydraulic cylinder, if the length of the culvert is large, it is necessary to continuously add pads behind the hydraulic cylinder to achieve the purpose of pushi...
