Abstract
The utility model provides an underground passage steel platform construction structures, includes the steel platform body, and steel platform both ends are equipped with the shoring mechanism, the shoring mechanism includes hydro-cylinder and many rocking arms, and the rocking arm both ends are articulated with steel platform and roof respectively, and the rocking arm middle part is rotated and is connected with the connecting rod, and the hydro-cylinder both ends are articulated with connecting rod and steel platform respectively. The utility model is used for solving the problem that the bottom of the steel platform supporting shaft influences the entrance and exit of engineering vehicles and machinery.
Description
Technical Field
The utility model relates to a construction structure of an underground passage steel platform.
Background
In Wuhan city subway 3, 4 # line Wangjiawan transfer station underground one-storey are the middle hole method of adopting the undercut and CRD method construction, existing advance the hole by building K3 landmass open cut shaft, construct the section B earlier, advance the hole by the section B construction section A section of constructing, need to build steel platform auxiliary construction during the construction, current steel platform landing leg supports the shaft bottom, can influence engineering vehicle and machinery business turn over to a certain extent, influence the construction progress.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a construction structure of an underground channel steel platform, which is used for solving the problem that the bottom of a steel platform supporting shaft influences the entry and exit of engineering vehicles and machinery.
In order to solve the problems, the technical scheme of the utility model is as follows:
the utility model provides an underground passage steel platform construction structures, includes the steel platform body, and steel platform both ends are equipped with the shoring mechanism, the shoring mechanism includes hydro-cylinder and many rocking arms, and the rocking arm both ends are articulated with steel platform and roof respectively, and the rocking arm middle part is rotated and is connected with the connecting rod, and the hydro-cylinder both ends are articulated with connecting rod and steel platform respectively.
And windlasses are fixedly arranged at two ends of the steel platform.
The steel platform is arranged in the shaft, anchor rods are respectively and fixedly arranged in concrete on two sides of the shaft mouth of the shaft, and the steel wire rope of the winch is connected with the anchor rods.
And a guardrail is arranged on the steel platform.
The utility model has the beneficial effects that: the existing supporting leg supported at the bottom of the vertical shaft is changed into a jacking mechanism, the jacking mechanism supports the steel platform on two side walls of the vertical shaft so as to empty the space below the steel platform, so that the engineering vehicle and machinery are not influenced to enter and exit, and meanwhile, the jacking mechanism also has a self-locking function, and the use safety and reliability of the steel platform are ensured.
Drawings
The utility model is further described below with reference to the accompanying drawings:
figure 1 is a schematic structural view of the present invention,
FIG. 2 is a schematic side view of the present invention.
In the figure: anchor rod 1, shaft 2, guardrail 3, hoist engine 4, steel platform 5, hydro-cylinder 6, rocking arm 7, roof 8, connecting rod 9.
Detailed Description
As shown in fig. 1 and 2, a construction structure for a steel platform of an underground passage comprises a steel platform 5 body, wherein two ends of the steel platform 5 are provided with jacking mechanisms, each jacking mechanism comprises an oil cylinder 6 and a plurality of rocker arms 7, two ends of each rocker arm 7 are respectively hinged with the steel platform 5 and a top plate 8, the middle of each rocker arm 7 is rotatably connected with a connecting rod 9, and two ends of each oil cylinder 6 are respectively hinged with the connecting rod 9 and the steel platform 5. After the steel platform 5 is placed in the vertical shaft 2, the oil cylinder 6 drives the top plate to tightly abut against the inner wall of the vertical shaft 2, the steel platform 5 is driven to move outwards by the aid of the gravity of the steel platform 5, so that the steel platform 5 is self-locked, and workers can construct underground passages on the steel platform 5.
And windlasses 4 are fixedly arranged at two ends of the steel platform 5. Hoist engine 4 is used for driving 5 up-and-down motion of steel platform, realizes adjusting from top to bottom of 5 positions of steel platform, and in the staff can transport shaft 2 through 5 convenient with article of steel platform in addition, hoist engine 4 can also play the insurance effect that prevents 5 falls of steel platform simultaneously.
The steel platform 5 is arranged in the vertical shaft 2, anchor rods 1 are respectively and fixedly arranged in concrete on two sides of a well mouth of the vertical shaft 2, a steel wire rope of a winch 4 is connected with the anchor rods 1, and the anchor rods 1 are welded and fixed with steel bars in the concrete of the vertical shaft 2 in advance. The connection of the steel wire rope of the winch 4 is convenient.
