Abstract

The invention discloses a prefabricated assembly type hollow cement concrete base plate structure and a construction method. Rectangular connecting grooves are formed in the front side and the rear side of the assembly type hollow cement concrete base plate, trapezoidal connecting grooves are formed in the left side and the right side of the assembly type hollow cement concrete base plate, evenly-distributed through holes perpendicular to the traveling direction are formed in the middle of a plate body, and PVC isolation plates are placed in the through holes to serve as connectors of two adjacent plates. The connecting grooves between a front plate and a rear plate can be mutually embedded and extruded to form a tenon-and-mortise type structure, and the connecting grooves between the leftside and the right side need to be bonded through joint materials. The construction method comprises the following steps: paving a subbase, paving a leveling layer on the subbase, mounting the base plates from the center line of the road to the two sides, mounting the cross sections one by one, and paving other pavement structure layers. Compared with a traditional cement concrete base construction mode, the method has the advantages of being good in heat insulation effect, rapid to install, easy and convenient to maintain, small in construction pollution and the like, and has wide application prospects.

Description

technical field

[0001] The invention relates to the technical field of prefabricated concrete base slabs, in particular to a prefabricated assembled hollow cement concrete base slab structure and a construction method. Background technique

[0002] With the development of my country's economy, under the guidance of the strategy of "transportation power", my country's road construction has achieved milestone development, and road construction technology and technology have become more mature. Cement concrete base has the characteristics of good integrity and large bearing capacity, and is widely used in road base construction. However, for traditional on-site construction, there are still many human factors (such as lax construction quality control, cutting corners, etc.) that greatly reduce the construction quality. Moreover, low-carbon and environmentally friendly construction is currently advocated, and many prefabricated pavement components well meet this requirement. ...
