Abstract

The utility model discloses a tunnel excavation support bench comprising a trolley door frame, a trolley truss, a trolley door opening and a trolley work platform, wherein the trolley work platform is divided into an upper layer and a lower layer, and is provided with a fixing platform, a telescopic platform I and a telescopic platform II, the fixing platform and the telescopic platform I are on the upper layer, and the telescopic platform II is disposed on the lower layer. The tunnel excavation support bench can shorten process work time and process connecting time, is widely used in tunnel construction, improves construction quality, accelerates schedule, and is remarkable in effect.

Description

The tunnel excavation support stand

Technical field

The utility model relates to a kind of stand, particularly the excavation supporting stand in a kind of constructing tunnel.

Background technology

Along with the development of society and the progress of science and technology, the excavation mechinery of Large Efficient such as the large section boring machine of TBM, various hammer drill, more and more is used in the tunnel excavation.But be subjected to the restriction of economic condition and the restriction of technical level can use efficient excavation mechinery and bring into play high efficiency tunnel considerably less.A large amount of tunnel excavations also remains artificial air drill excavation.And artificial air drill excavation is subjected to the restriction of tunneling operation height will divide many bench excavations.This compares with the stand excavation increases operation, can not take full advantage of the labour, has increased like this time that excavation, supporting circulate, thereby has caused construction speed slow.Therefore the research of tunnel excavation, supporting stand can reduce the cycle time for working of constructing tunnel, guarantees that construction safety and quality have very high practical value.And existing stand function singleness does not have also that a stand can be applied to excavate simultaneously, a step of advance support, preliminary bracing construction.

Summary of the invention

Goal of the invention of the present utility model is in order to overcome the shortcoming in the above-mentioned background technology, to provide a kind of making simple, being fit to the tunnel excavation support stand of progress multiple constructing tunnel operation and that can improve construction quality.

The technical solution of the utility model is: a kind of tunnel excavation support stand, comprise chassis door frame, chassis truss, chassis door opening and chassis job platform, described chassis job platform is divided into up and down two-layer, total fixed platform, scaling platform I, three job platforms of scaling platform II, fixed platform and the scaling platform I upper strata that coexists wherein, the scaling platform II is in lower floor.

Described chassis door frame has three Pin door frames to be welded, and door frame is formed by the welding of two Pin I18 i iron, and the chassis truss is spliced by single Pin I18 i iron and the channel-section steel that adopts I20.

The bracing frame position of described chassis door frame is provided with for mobile tire, and mobile power is mechanical push-and-pull, such as loader.

All completely be covered with reinforced mesh on the described tunnel excavation support stand on each layer.

The beneficial effects of the utility model are: the utility model is applicable to positive benching tunnelling method and full section method construction operation, be applicable in tunnel survey operation, bursting work, advance support operation, the preliminary bracing anchor bolt construction, bow member installation, the laying of net sheet, sprayed mortar, slip casting, owe to dig the operations such as processing.Can shorten working procedure duration, reduce the procedure connection time.Be widely used in the tunnel constructing tunnel, improve construction quality and progress, effect is remarkable.

Description of drawings

Fig. 1 is stereogram of the present utility model;

Fig. 2 is the front view of Fig. 1;

Wherein: 1, chassis door frame, 2, the chassis truss, 3, the chassis door opening, 4, diagonal brace, 5, fixed platform, 6, the scaling platform I, 7, the scaling platform II, 8, tire.

The specific embodiment

Present embodiment shown in Fig. 1 is extremely shown in Figure 2:

Chassis door frame (1): door frame adopts the welding of 2 Pin I18 i iron, and the long 6.1m of chassis, high 4.0m altogether three products door frame are welded.Door frame assembly unit in the tunnel after processing district blanking, welding well.

Chassis truss (2): adopt single Pin I18 i iron, diagonal brace all adopts the I20 channel-section steel.

Chassis door opening (3): will be placed in the tunnel for making things convenient for the constructing tunnel stand, so stand must arrange door opening.The door opening size is determined according to tunnel excavation section, Work machine size and the stressed safety of stand.The wide * height of door opening size is 6.8m*4.3m, and is added with diagonal brace (4).

The chassis job platform: totally two layers, three job platforms, every interlamellar spacing is 2.1m, scaling platform I (6) and scaling platform II (7) they are the telescopic movable foot platform.The canned paragraph length of scaling platform I is 90cm, and for I18 i iron weld length on its web is 90cm Φ 108 seamless steel pipes, intubating length is Φ 80 seamless steel pipes of 1.1m in the steel pipe.Scaling platform II (7) is 1.6m Φ 108 seamless steel pipes for the I18 i iron in its web welding one length, intubating length is Φ 80 seamless steel pipes of 2.5m in the steel pipe, and to process a height by the center line side with the I18 i iron at platform be that 20cm, width are that the pedal of 1.0m is in order to excavate job execution.Fixed platform (5), width are 6.8m, are convenience, the safety that guarantees positive vault construction operation, and the split heads of a wide 3.4m, high 0.4m is set in the centre.It is long that fixed platform (5) is extended 1.3m near the face end, is in order to prevent that face excavation irregularity from can not design trolley running to the scope of operation, strengthened the safety of operation like this.

Scaling platform I (6) and scaling platform II (7) design are for the variation that is applicable to section and avoid trolley running to destroy preliminary bracing face and damage stand.

The stand connected mode adopts welding, and each layer of chassis completely spreads reinforced mesh.

The trolley running mode is rubber-tyred, tire (8) external diameter 110cm.Power is that mechanical push-and-pull is mainly loader.

At chassis switchbox, airduct, water pipe and gate valve are installed, safe voltage is used in the chassis illumination, guarantees construction safety.Waning and the extension protection sign of protection is set around stand.

The scope of application of the present utility model: be applicable to positive benching tunnelling method and full section method construction operation; Be applicable to tunnel survey operation, bursting work, advance support operation, preliminary bracing (anchor bolt construction, bow member are installed, the net sheet is laid, sprayed mortar), slip casting, owe to dig the operation such as processing.
