Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0019] First, compare the attached Figure 1-7 , each component and function of the present invention are described as follows:

[0020] The model of the total station 1-1 is TS15 or TS50, and the CPⅢ point belongs to the CPⅢ track basic control network. This network is a reference network established on the inner tube wall of the tunnel by using the precise wire points provided by the owner in the tunnel; before starting the operation, Fix the total station trolley 1 at the starting position of the operation and keep it still during the entire cycle operation.

[0021] Precision leveling machine 2 consists of prism 2-1, digital hydraulic cylinder 2-2, servo motor 2-3, hydraulic jacking system 2-4, control computer 2-5, skeleton 2-6, hydraulic motor 2-7, and travel Wheel 2-8, vibrating plate 2-9 form. The hydraulic jacking system 2-4 is used to extend the ...

Abstract

The invention discloses a subway track plate base construction device which comprises a total station cart (1), a precision flattening machine (2) and a coarse vibrator (3). The total station cart (1), the precision flattening machine (2) and the coarse vibrator (3) form a whole. The total station cart (1) is in radio connection with the precision flattening machine (2) and the coarse vibrator (3). A total station (1-1) is in radio connection with a precision flattening machine control computer (2-5) and a coarse vibrator control computer (3-4). The precision flattening machine control computer (2-5) and the coarse vibrator control computer (3-4) are connected with a precision flattening machine hydraulic oil pump (2-7), a coarse vibrator hydraulic oil pump (3-10), a precision flattening machine digital oil cylinder (2-2), a coarse vibrator digital oil cylinder (3-2), a precision flattening machine servo motor (2-3) and a coarse vibrator servo motor (3-3) respectively through a control line.

Description

technical field [0001] The invention relates to concrete construction equipment for a subway track slab base, belonging to the technical field of subway track engineering construction. Background technique [0002] With the gradual development of subway construction in various cities, the construction technology of subway has also changed. Now the overall track bed construction of subway track engineering is cast-in-place concrete technology. With the development of technology and the improvement of requirements, the integral track bed of subway track engineering began to develop in the direction of prefabricated slabs, that is, the factory produced the integral track bed according to the technical requirements, and then transported it to the construction site for installation. This process requires the track slab base The continuous height difference of the seat plane is ≤3mm. Existing concrete paver trucks in the market are generally used for construction in wide places s...
