Problems solved by technology

[0002] At present, the formwork support of domestic subway projects mostly adopts the form of steel pipe frame (or bowl buckle frame) + wooden formwork; the erection of the steel pipe frame requires a lot of manpower, the amount of materials is relatively large, the installation and disassembly cycle is long, and the details need to be controlled during the erection process There are many, the quality of construction is not suitable to be guaranteed, and there are greater safety risks in terms of quality and personnel; therefore, it is difficult to adapt to the needs of the market in terms of safety, quality, cost, management and manpower input by using traditional technologies

[0061] Step S4: Assembling the formwork trolley; the formwork trolley includes the formwork main part, the connecting screw connected with the formwork main part and the hydraulic jack, and the circuit and oil pipe installed on the formwork main part; the formwork main part includes the chassis , the walking system installed on the lower part of the chassis, ...

Embodiment 2

[0084] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, the construction method of the self-propelled integral hydraulic formwork trolley for the side wall of the subway station specifically includes the following construction steps:

[0085] Step S1: construction preparation.

[0086] Step S2: Installation of embedded parts.

[0087] Step S3: Laying of formwork trolley tracks. Specifically, first measure the exact position of the track of the positioning formwork trolley. After the measurement is completed, the formwork trolley track is installed.

[0088] Before the template trolley is installed, the bottom plate is cleaned, the exact position of the track of the positioning trolley is measured, the base surface of the track is processed, the track is installed, and the two sides of the track are fixed with rivets.

[0089] Step S4: Assembling the template trolley.

[0090] The formwork trolley includes a formwork ma...

Embodiment 3

[0124] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, the step S6 specifically includes the following construction steps:

[0125] Step S61: place the template trolley on the track;

[0126] Step S62: supporting the lower end of the top support diagonal bar on the installed reaction force device;

[0127] Step S63: After the formwork is in place, install the fastening bolts of the horizontal tie rods at the bottom of the formwork for formwork debugging;

[0128] Step S64: After the formwork is debugged, fasten the formwork bottom horizontal tie bar and the top support diagonal bar in sequence;

[0129] Step S65: Install the anti-floating device, and complete the reinforcement of the template trolley. .

[0130]It should be noted that through the above improvements, after the trolley travels to the designated position, the trolley will be stably seated on the track through the steel legs; the lower end of the top suppo...

Abstract

The invention discloses a construction method of a metro station side wall self-walking type integral hydraulic formwork trolley. The method specifically includes the following construction steps of construction preparation, installation of embedded parts, laying of formwork trolley rails, assembling of a formwork trolley, positioning of a formwork, reinforcing of the trolley, side wall concrete casting, demolding of the formwork, displacement of the trolley, and cleaning of the formwork. Compared with the prior art and the traditional technology, the method is simple in process, convenient to use and suitable for large station straightway line production; by means of large steel formworks, after reinforcing measures are taken, the structure is stable, formwork explosion and formwork shifting can not easily occur, safety is high, and the overall construction quality is easy to guarantee; the method saves energy and is environmentally friendly, rapid in construction procedure and high in efficiency; by means of mechanical operation, manpower input is small, loss is small, and the repeated utilization rate is high.
