Embodiment 1

[0018] Embodiment 1: A kind of one-time pouring type steel formwork trolley in desert tunnel, see figure 1 , the outer formwork support includes two parallel outer formwork trusses 2 and several tie rods 1 at the top. The upper ends of the two outer mold trusses 2 are fixed together by the pull rod 1, and a sliding and locking structure can also be set between the two outer mold trusses 2 and the top pull rod 1.

[0019] The lower ends of the two outer mold trusses 2 are respectively provided with an outer walking frame 5, and a lifting mechanism is arranged between the outer mold trusses 2 and the outer walking frame 5; the lifting mechanism 26 is an adjustable bolt or a jack.

[0020] The lower ends of the two outer walking frames 5 are provided with outer rail wheels 6 and outer rails 7 respectively. Thus the outer formwork and its components can translate forward along the track 7 .

[0021] The outer formwork includes two outer formworks 3 and one outer top formwork 4 ....

Embodiment 2

[0030] Example 2: see figure 1 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that a height fine-tuning mechanism for controlling the height change of the inner mold supporting plate is provided between the top of the inner mold supporting plate 8 and the inner legs 13. That is, an adjusting nut 20 is arranged on the connecting rod between the top of the inner mold supporting plate and the inner leg, for adjusting the height of the connecting rod.

Embodiment 3

[0031] Embodiment 3: see figure 1 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that a center line adjustment mechanism that can make the inner mold bracket move left and right is provided between the top of the inner mold support plate 8 and the inner legs 13. The center line adjustment mechanism is provided with a horizontal flat groove on the upper part of the inner support leg, and an adjustment knob 24 is arranged on the side wall of the flat groove, and the bottom of the connecting rod fixed to the top of the inner mold supporting plate is sleeved in the flat groove, and the adjustment knob is connected to the said flat groove. The side walls of the connecting rod are butted.

Abstract

The invention discloses a one-step pouring type steel mould trolley and a pouring method for concealed channels in deserts. The one-step pouring type steel mould trolley comprises outer mould plates, a support of the outer mould plates, inner mould plates and a support of the inner mould plates; outer track wheels and outer tracks are respectively arranged at the lower ends of outer traveling frames and the lower ends of inner traveling frames; outer side mould plates, an outer top mould plate, inner side mould plates and an inner top mould plate form a 'square' pouring channel in an enclosing manner; vibrators are fixed onto outer mould trusses and inner mould support plates; feed inlets are respectively formed in the outer side mould plates, the outer top mould plate and an inner bottom mould plate. The one-step pouring type steel mould trolley and the pouring method have the advantages that the outer mould trusses and an outer mould form an inverted-U-shaped semi-closed protective cover, operation such as reinforcing steel bar tying and foundation construction can be completed in the inverted-U-shaped semi-closed protective cover, the one-step pouring type steel mould trolley and the pouring method are favorable for protecting workers against severe weather such as sandstorm, a sunshade space can be provided for the workers, the comfortable degree of the work space can be increased, sun exposure protection for newly built concrete layers of foundations can be advantageously improved, and accordingly construction progress can be prevented from being interrupted by influence of weather change factors.

Description

technical field [0001] The invention belongs to the field of road construction for controlling deserts, and in particular relates to a one-time pouring type steel mold trolley and a pouring method for a dark tunnel in a desert. Background technique [0002] Conquering deserts and marching into deserts is an important part of the Western Development, and it is also one of the problems that people are eager to solve in the 21st century. With the steady implementation of the western development strategy, a large number of projects will be built in desert areas, requiring the help of large machinery and equipment. The desert tunnel can provide sufficient water sources for major projects and is an important transportation channel. However, due to the special situation that the desert is not conducive to transportation, the desert underpass is not easy to realize through prefabrication and transportation, and it is necessary to carry out underpass construction in the desert, whic...
