Stable construction device

Abstract

A stable construction device comprises a formwork, a driving device, a supporting block, a connecting rod, a walking system, a base, a main bridge, a square table, a supporting column, a workbench, atraction claw, a traction rod, a traction wheel, a storage type rack, a storage type fence, a front bridge, a slope, a rear bridge, a traction rope bayonet and a concrete slab, wherein supporting legsare arranged on the lower side of the base, each supporting leg comprises a connecting frame, an installing hole, universal hinge pieces, supporting foots and rubber cushions, a bolt penetrates through each installing hole so that the corresponding connecting frame can be connected to the base, the two ends of each connecting frame are each provided with one universal hinge piece, the lower sideof each universal hinge piece is connected with one supporting foot, each supporting foot can rotate relative to the corresponding connecting frame through the corresponding universal hinge piece so as to adapt to different road conditions, and the lower side of each supporting foot is provided with one rubber cushion.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a smooth construction device. Background technique [0002] In the construction process of various domestic mine roadways, railway and highway tunnels, water conservancy culverts, various underground projects, high-rise building foundation pits, military projects, etc., the inverted arch is the basic structure of the tunnel and is the core part of the entire tunnel. The general process of inverted arch construction includes excavation, slag removal, arch erection, concrete spray protection, binding steel bars, formwork, and pouring concrete. A variety of construction equipment includes inverted arch trolleys, inverted arch trestles, wet sprayers, arch installation machines, etc. [0003] In the actual use of various construction equipment, there are the following problems: [0004] 1. In the prior art, the inverted arch trolley, inverted arch trestle, wet spray machine, and a...

AI Technical Summary

Problems solved by technology

Various construction equipments interact with each other, and the procurement, transportation, coordination, and simultaneous construction of multiple equipments are cumbersome

[0005] 2. The lining pouring of the prior art requires special tools such as a trolley or a bottom working vehicle to move the formwork. The trolley type has a single moving function, while the bottom working vehicle needs to be equipped with a separate track, which greatly increases the construction cost and work efficiency

[0006] 3. Inverted arch trestle bridges in the prior art pay more and more attention to the length of the front bridge. It is not uncommon for the front bridge to be more than ten meters long. The front axle has high requirements for the driving force of the lifting cylinder, and the counterweight requirements for the main axle are also greatly increased.

[0007] 4. In the existing technology, the lining is poured from a high place, and a bench is often used. The bench is bulky and heavy, and cannot be accommodated, which has a great impact on both construction efficiency and cost.

[0008] 5. When the trestle bridge in the prior art moves, it often only relies on the track and a pair of wheels to move, it is difficult to adapt to the complex terrain conditions of the tunnel, and it is prone to slipping or stagnation

[0009] 6. When pouring concrete in the prior art, it is often necessary to transport additional concrete formwork, which interferes with trestles or trolleys, affects each other, and is inefficient

[0010] 7. The trestle bridge in the prior art is difficult to move smoothly due to the influence of muck in the tunnel when moving, and it is easy to cause inclination
