Problems solved by technology
However, due to the relatively long time of concrete pouring, the concrete components poured in the early stage will be exposed to the air for a long time, and it is easy to cause plastic cracks or temperature cracks due to untimely maintenance, which will affect the quality of concrete components.

Embodiment Construction
[0033] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0034] Such as figure 1 and figure 2 as shown,
[0035] A process for prefabricating and installing large slabs in wharf wearing layers and road storage yards, the specific steps are as follows:
[0036] a. Factory slab prefabrication
[0037] According to the design size, the concrete undercarriage 1 is prefabricated in the factory in advance. The concrete undercarriage 1 is surrounded by shaped steel formwork, and bolt holes are set at the four corners. Bolts 2 are pre-embedded in the bolt holes as lifting points, and finally the prefabricated concrete components are obtained. 3;
[0038] b. Factory unified standard maintenance
[0039] The prefabricated concrete components 3 are uniformly maintained;
[0040] c. to install
[0041] During installation, a grouting layer 4 of 1-2 cm is reserved at the bottom, and an inverted T-shaped positioning stee...

The invention provides a dock wearing layer and road storage yard large board prefabricating and mounting technique. The dock wearing layer and road storage yard large board prefabricating and mounting technique comprises the specific steps that according to the design size, a concrete bottom blank is prefabricated in advance in a factory, a shaped steel formwork is adopted on the periphery of theconcrete bottom blank, bolt holes are formed in the four corners of the concrete bottom blank, bolts are pre-buried in the bolt holes, and finally prefabricated concrete components are obtained; theprefabricated concrete components are cured uniformly; in mounting, a grouting layer is reserved at the bottom, and inverted-T-shaped positioning steel bars are fixed between the two adjacent concretecomponents in advance; then the two concrete components are hoisted to the corresponding positions through an auto crane, and the two concrete components are adhered through an adhesion material; a hoisting point is dismounted after mounting is completed, and a hoisting hole is blocked; an epoxy grouting material is injected into the grouting layer; and pouring is conducted. The dock wearing layer and road storage yard large board prefabricating and mounting technique has the beneficial effects that the labor force is small, the safety coefficient is high, the production efficiency is high, the construction quality is good, the cost is low, and environment-friendly development is achieved.
Description
technical field [0001] The invention relates to the technical field of large slab concrete construction of a wharf wearing layer and a road yard, in particular to a prefabricated installation process for a wharf wearing layer and a large slab of a road yard. Background technique [0002] Concrete is referred to as "concrete" for short: it refers to the collective name of engineering composite materials that cement aggregates into a whole by cementitious materials. Concrete usually refers to the cement concrete that uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water with or without admixtures and admixtures in a certain proportion, and is obtained by stirring, molding and curing. Called ordinary concrete, it is widely used in civil engineering. [0003] With the innovative development of construction technology, coupled with the increasing content of project construction, mass concrete construction technology is being widely use...
