Description
Technical Field
The utility model belongs to the technical field of shield construction, and particularly discloses a walking, rotary mold and template transverse moving assembly of a needle beam type rotary mold full-circle lining trolley.
Background
In recent years, along with city expansion, diversion and water delivery tunnels are gradually increased, compared with urban subway shield tunnels, the diversion and water delivery shield tunnels have small sections and small turning radii, and secondary lining concrete needs to be poured on the basis of shield segments.
The diversion and water delivery shield tunnel is circular in shape, and a circular needle beam type lining trolley is needed to be adopted for lining construction, so that the integrity of lining concrete can be ensured. The longitudinal axis of the existing needle beam type lining trolley is linear, and the lining trolley cannot be well matched with a curve section when the curve section is constructed, so that in the curve section, a method of reducing the length of concrete poured into the lining trolley at one time is adopted to prevent the lining thickness from meeting the design requirement, or a method of disassembling a needle beam, dividing the needle beam into 2 trolleys and installing a wedge plate to adapt to the curve section is adopted.
The conventional linear pin beam type lining trolley has the following disadvantages:
1. when the curve section is constructed, in order to ensure the lining thickness, the one-time lining length cannot be too long, the number of lining concrete sections is large, the number of construction joints is large, and the quality risk is large;
2. erecting the template and constructing a large amount of waterproof engineering;
3. the lining times are many, the progress is slow, and the labor cost and the equipment cost are high;
4. because the lining concrete has more sections, the construction interference is large, and the organization is difficult.
The traditional stitch-removing type lining trolley for installing the wedge-shaped plate has the following defects:
1. the step of disassembling and installing the wedge-shaped plate of the needle beam is complex, the accuracy of the lining trolley is influenced by repeated disassembly and assembly, and the trolley parts are easy to be locally formed, so that the service life is influenced;
2. the time for installing and dismantling the wedge-shaped template is long, the construction progress is influenced, and the labor cost is high.
In order to solve the problems, the applicant designs the templates, and proposes that the surfaces of the two adjacent templates which are connected with each other are oblique to the axis of the tunnel, and the templates can be rotated to form a straight-line cylindrical structure adaptive to a straight section of the tunnel or a broken-line cylindrical structure adaptive to a curved section of the tunnel. However, it is necessary to solve the problems of how to rotate the template, how to center the template after the template rotates, and how to excessively pull the pulley by the steel wire rope in the needle beam due to the misalignment of the axes of the needle beam and the template when the trolley is located in the curved section of the tunnel.
