Abstract
The utility model relates to a shield barrier-free launching apparatus which comprises an end well, a steel lantern ring, a shield tunneling machine, glass fiber ribs and a well end enclosing structure, wherein the end well is vertically arranged; the steel lantern ring is horizontally inserted into the end well; the shield tunneling machine is received in the steel lantern ring; the end well enclosing structure is disposed at one side of the end well; and the glass fiber ribs are arranged in the well end enclosing structure to form a glass fiber rib area. Through sleeving the steel lantern ring on the shield tunneling machine and arranging glass fiber ribs on the well end enclosing structure, the shield launching process of the shield barrier-free launching apparatus provided by the utility model is fast, safe and low in cost, no work of manually breaking down reinforced concrete of the end well enclosing structure is needed, and thus the shield barrier-free launching apparatus is notable in economic and social benefits.
Description
[technical field]
The utility model relates to a kind of shield structure device, is specifically related to the accessible device that starts of a kind of shield structure, belongs to the building machinery technical field.
[background technology]
" shield construction " is a kind of higher set of tunneling construction method of mechanization and automaticity, and since the sixties in 20th century, western developed country is applied to this technology the construction of city underground and large size city outlet tunnel in a large number.China recent years also begins to adopt this top technology in Construction of City Tunnel, to substitute the original fluting open cut that falls behind or shallow burial hidden digging construction.
Shield launching is a very important link of shield construction.There is following drawback in the shield launching technology at present: (1) end well is reinforced difficulty: purpose is the stability that increases place, the hole soil body, makes stake (wall) body cut the rear hole soil body and does not cave in, and reinforcing scope is generally 9m*6m.The reinforcing of shield end well at present generally has following several method, high-pressure rotary spraying method, Deep Mixing Method, grouting and reinforcing method, freezing process, element stake (wall) method etc., these methods all have certain compliance in the shallow embedding situation, in the situation that buried depth is larger, the effect of these methods is difficult to guarantee, that is to say that these methods are difficult to adapt to high hydraulic pressure, high soil pressure and the harder condition of soil property, particularly some areas are met ovum erratic boulder, underground water sometimes in the Pekinese.(2) cutting stake (wall) body difficulty, is the stage of risk maximum in cutting process.Before address, at the portal place owing to there being stake (wall) body to prop up the soil body that is keeping off thereafter, in case cut pile body, the soil body exposes, the equilibrium state on stratum, termination is broken, if soil mass property is relatively poor or have underground water to exist, the hole soil body is caved in, thereby cause surface subsidence, serious meeting causes personnel casualty accidents; For buried situation, not only difficulty is large, long in time limit to cut the thick temporary lining steel concrete diaphragm wall that reaches nearly 1.5m, and risk is larger.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of accessible device that starts of structure improved shield structure that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of Stability Analysis of Structures, the accessible device that starts of shield structure that easy to use and cost is low.
For achieving the above object, the technical scheme that the utility model is taked is: the accessible device that starts of a kind of shield structure, and it comprises end well, steel collar, shield machine, glass fiber muscle and end well space enclosing structure; Wherein, described end well is vertical setting; Described steel collar level is inserted in end well; Described shield machine is contained in steel collar; Described end well space enclosing structure is positioned at a side of end well; Described glass fiber muscle is arranged in and forms a glass fiber muscle district in the end well space enclosing structure.
The accessible device that starts of shield structure of the present utility model further is set to: the diameter in described glass fiber muscle district is greater than the diameter of steel collar.
Compared with prior art, the utlity model has following beneficial effect: the accessible device that starts of shield structure of the present utility model is by sheathed steel collar on shield machine, arrange the glass fiber muscle on the end well space enclosing structure, thereby make that shield structure process has that speed is fast, safety, cost is low, do not need manually to abolish end well space enclosing structure steel concrete, economic benefit, social benefit are very obvious.
[description of drawings]
Fig. 1 is the structural representation of the accessible device that starts of shield structure of the present utility model.
[specific embodiment]
See also shown in Figure of description 1, the utility model is the accessible device that starts of a kind of shield structure, and it is comprised of several parts such as end well 1, steel collar 2, shield machine 3, glass fiber muscle 4 and end well space enclosing structures 5.
Wherein, described end well 1 is vertical setting.Described steel collar 2 levels are inserted in end well 1.
Described shield machine 3 is contained in steel collar 2.
Described end well space enclosing structure 5 is positioned at a side of end well 1.Described glass fiber muscle 4 is arranged in and forms a glass fiber muscle district in end well space enclosing structure 5.The diameter in described glass fiber muscle district is greater than the diameter of steel collar 2.
The accessible device setting principle that starts of shield structure of the present utility model is as follows: by sheathed steel collar 2 on shield machine 3, arrange glass fiber muscle 4 on end well space enclosing structure 5, locate thereby make shield machine be easy to the shield structure, and at end well 1 place, the hole soil body that do not need reinforcement.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
Claims (2)
1. the accessible device that starts of shield structure, is characterized in that: comprise end well, steel collar, shield machine, glass fiber muscle and end well space enclosing structure; Wherein, described end well is vertical setting; Described steel collar level is inserted in end well; Described shield machine is contained in steel collar; Described end well space enclosing structure is positioned at a side of end well; Described glass fiber muscle is arranged in and forms a glass fiber muscle district in the end well space enclosing structure.
2. the accessible device that starts of shield structure as claimed in claim 1 is characterized in that: the diameter in described glass fiber muscle district is greater than the diameter of steel collar.
