Description
Technical Field
The utility model relates to a shield constructs technical field, especially relates to a shield constructs tunnelling dregs improvement device suitable for hard clay stratum.
Background
The shield tunnel construction technology is widely applied in the fields of domestic subway markets, water delivery tunnels, electric power tunnels and the like. Whether the shield tunneling can be smoothly carried out exists, the tunneling efficiency is directly related to the improvement of the shield unearthed muck, and the improvement of the muck of the stratum which is difficult to treat is a key process of shield construction.
The hard clay stratum belongs to one of the intractable strata encountered in shield construction, the soil is cut by a shield cutter head and then becomes block-shaped, and stirring for a longer time than usual and more dregs modifier foams are required to be soaked into the soil blocks to reduce digging resistance so as to cut the dregs into small soil blocks. If the dregs improvement effect is not good, or the clay is too hard, lead to dregs cutting effect bad, will cause the massive lump-forming clay to directly drop to the transportation belt through the screw machine, it is fast to become the smooth clay in square surface greatly, can lead to it to skid at belt slope section, lead to the fact to pile up along with the unearthing of subsequent same type soil piece, finally make this position soil piece pile up too much and cause earth directly to roll off from the belt, can pound bad equipment or pound the staff, form unsafe factor, also can cause extra clear mud task, influence construction overall progress.
To how to make the convenient transportation of dregs that falls on the belt feeder when meetting hard clay stratum, this utility provides a shield structure tunnelling dregs improvement device suitable for hard clay stratum.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the shield that is applicable to hard clay stratum that proposes is constructed and is tunneled dregs improvement device, the utility model discloses a cutter arbor cuts dregs, can solve dregs improvement effect poor, the belt easily takes place to skid, earth drops the scheduling problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a shield constructs tunnelling dregs improvement device suitable for hard clay stratum, includes the screw machine unearthed mouth, the screw machine unearthed mouth can be dismantled and is connected with the frame, and the upper and lower lateral wall of frame is equipped with the installing port, and the inner wall fixedly connected with dead lever of installing port slides on the dead lever and has cup jointed the slider, connects through the cutter arbor between two sliders, is equipped with the cutting part on the cutter arbor.
Preferably, the lateral wall of the screw machine soil outlet is connected with a central lug, the inclined plane of the central lug is connected with an inclined block in a sliding manner, the inclined block is connected with a screw rod in a rotating manner, a fixed block is sleeved on the screw rod in a threaded manner, and the fixed block is connected with the outer frame.
Preferably, an elastic gasket is arranged between the opening edge of the soil outlet of the screw machine and the outer frame.
Preferably, a fastening bolt is connected to the sliding block in a threaded manner.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model has simple structure, utilizes the extrusion force of the screw machine to the soil as the power source for cutting the muck, cuts the muck through the cutter bar, can solve the problems of poor muck improvement effect, easy slipping of the belt, falling of the soil and the like, provides large cutting force for cutting clay, realizes automatic cutting, stops potential safety hazard and lightens the cleaning work in the tunnel; the strength and rigidity are high, and the cutting capability is strong; simple structure, convenient to use, cost economy, effect are showing, cut the clod time when reducing the tunnelling, improve the efficiency of construction.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic sectional view taken along line a-a in fig. 1.
In the figure: the device comprises an elastic gasket 1, a fixed block 2, an inclined block 3, a screw machine soil outlet 4, a central bump 5, an outer frame 6, a screw 7, a fixed rod 8, a sliding block 9 and a cutter bar 10.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a shield tunneling muck improvement device suitable for hard clay stratum comprises a screw machine unearthing port 4, wherein the screw machine unearthing port 4 is detachably connected with an outer frame 6, the upper side wall and the lower side wall of the outer frame 6 are provided with mounting ports, the inner wall of each mounting port is fixedly connected with a fixed rod 8, slide blocks 9 are sleeved on the fixed rods 8 in a sliding mode, the two slide blocks 9 are connected through a cutter bar 10, and a cutting part is arranged on the cutter bar 10.
The lateral wall of screw machine unearthing mouth 4 is connected with central lug 5, and the inclined plane sliding connection of central lug 5 has sloping block 3, and sloping block 3 rotates and is connected with screw rod 7, and the screw thread has cup jointed fixed block 2 on the screw rod 7, and fixed block 2 is connected with frame 6, and through rotating screw rod 7, drive sloping block 3 and central lug 5 relative slip, realize the joint, link together frame 6 and screw machine unearthing mouth 4.
