Description

Structure for solving different height walking and horizontal transportation of trailers before and after shield starting

Technical Field

The utility model relates to a shield constructs quick-witted technical field that starts, concretely relates to solve shield structure that trailer is high walking and horizontal transport not together around starting.

Background

When a shield starts, a sinking section can be arranged on a main structure of a connecting section of a foundation pit, so that a trailer at the back and the front are different in height, the trailer at the back cannot normally cross the sinking section forward, and in order to meet the requirement that the shield starts the walking of a plurality of trailers at the back and the horizontal transportation of duct pieces and internal structure prefabricated parts, the traditional method is to adopt a mode of pouring an arc guide platform 1 (shown in figure 1) and stacking an internal opening sub-part 2 of a shield interval at a lower position to heighten the sinking section of the main structure of the foundation pit so as to solve the driving and horizontal transportation of the plurality of trailers at the back.

However, in practical application of the method, the maximum elevation allowed by the arc-shaped guide platform for traveling of No. 1 trailer wheels and transportation of duct pieces is met, a concrete layer of about 25cm is still required to be additionally paved on the arc-shaped guide platform 1 before stacking the opening sub-components 2 to be as high as the height of a constructed roadway plate, the concrete is required to be as strong as the height of the constructed roadway plate after pouring concrete, the construction period is greatly influenced, and a large amount of concrete and waste opening sub-components are required to be chiseled when the roadway plate and the partition wall are constructed in the later period, so that waste of resources and cost is caused.

Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.

In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present application. References to "first," "second," etc. in this application are intended to distinguish between similar items and not necessarily to describe a particular order or sequence.

Example 1: a structure for solving the problem of different height walking and horizontal transportation of trailers before and after shield starting is disclosed, and comprises an arc-shaped track row middle part 4, an A-block upright post 6 and an inverted T-shaped supporting piece, wherein a sheet feeding machine 3 passes through the arc-shaped track row middle part 4, the sum of the heights of the arc-shaped track row middle part 4 and the sheet feeding machine 3 is smaller than the bottom surface height of the trailer, and a No. 1 trailer 5 and the sheet feeding machine 3 can be ensured to advance vertically and parallelly.

Need prepare type of falling T support piece after 1 number trailer 5 passes through, it includes lane board 10, mid wall 8, longeron 11, spliced pole 9, mid wall 8 supports in the bottom intermediate position of lane board 10, longeron 11 sets up in the both sides of lane board, spliced pole 9 is fixed in the below of longeron, make lane board 10 and the foundation ditch major structure in the effect of spliced pole 9 in the lane board highly uniform that has accomplished, guarantee 2 number trailer 7 can steadily through this section of sinking.

The A upright posts 6 and the inverted T-shaped supporting pieces are spliced and installed in a tenon-and-mortise mode, and splicing margins of 10mm are reserved at the front, the rear, the left and the right (according to the specific situation of the project). Before installation, a butyronitrile cork rubber gasket is adhered to the bottom of the joint of the inverted T-shaped supporting piece and the A upright post 6, and a seam is filled; and gaps in the vertical direction around the joint are wedged tightly by steel gaskets. To accommodate the passage of trailer number 2, the width of the lane plates 10 is increased as necessary to be greater than the spacing of the trailer wheels. A piece of stand 6 that satisfies 1 trailer walking can cast-in-place completion when the major structure is under construction, and pre-buried steel sheet is in order to install trailer walking track roof beam. The A upright columns 6, the longitudinal beams 11, the roadway plates 10 and the partition walls 8 need to be prefabricated in blocks and sections, after a plurality of trailer sections move to the distance, the inverted T-shaped part is assembled, the first section needs to be fixed with the bottom plate, and in order to ensure the stability of the whole structure, every two adjacent sections can be fixed by adopting a tensioning device in an auxiliary mode.

This embodiment adopts the following structural optimization method who faces the combination forever, cancel the arc guide table under No. 1 trailer, the arc section of track below the feeding machine only remains the mid portion, satisfy the transportation of section of jurisdiction under No. 1 trailer, the walking of No. 1 trailer is provided by A piece stand 6 under the guidance tape, the walking of trailer at the back is provided by prefabricated type of falling T support piece, because the trailer wheel interval of several sections differs around, need enlarge the stand size after the axis interval contrast with A piece stand 6, for guaranteeing construction quality and later stage operation safety, can suitably encrypt the stand.

While the present invention has been described in detail with reference to the drawings and examples, it will be understood by those skilled in the art that various changes in the specific parameters of the embodiments described above may be made or equivalents may be substituted for elements, structures or materials thereof without departing from the spirit of the invention to form various embodiments, which are intended to be part of the scope of the invention and not be described in detail herein.
