Embodiment Construction

[0019] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0020] Such as figure 1 Shown, a kind of slab culvert construction technique is characterized in that comprising the following steps:

[0021] S1, measurement and setting out, according to the requirements of the design drawings, use the total station to stake out the center line, then sprinkle the base line with white lime according to the center line, determine the excavation side line, and indicate the elevation and excavation depth, and at the same time determine the position, direction, Positioning and laying out of the base size, elevation, etc., so that construction personnel can quickly identify the location during construction.

[0022] S2, Excavation of the foundation trench. Excavator excavation is used for excavation of the foundation trench, and dump trucks are operated together. When excavating the foundation trench,...

Abstract

The invention discloses a cover plate culvert construction process which is characterized by comprising the following steps: staking out in survey, foundation trench excavation, foundation and platform body building, platform cap construction, cover plate installation, waterproof layer making and backfilling. According to the implementation of the construction process, the cover plate culvert is used as a culvert, no large prefabricated part exists in the construction process, and prefabrication in the construction site is facilitated; the construction process is suitable for construction in some rugged mountainous areas, meanwhile, the flood discharge capacity of the cover plate culvert is high; normal passing of flood can be guaranteed in rainy seasons, and the situation that the flood overflows the road surface, and road and driving safety are affected can be avoided.

Description

technical field [0001] The invention belongs to the field of road construction technology, and in particular relates to a slab culvert construction technology. Background technique [0002] In road construction in mountainous areas, round pipe culverts are often used to cross some small valleys, but round pipe culverts need to be prefabricated. In some rugged mountainous areas, there are no prefabricated conditions on site, and transportation is inconvenient, which limits the use of round pipe culverts. At the same time, the flood discharge capacity of circular pipe culverts is poor. In rainy seasons, it is easy to cause floods to overflow the road surface, affecting the safety of roads and driving. Road construction in mountains. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a slab culvert construction process, which can solve the problem of difficult construction in the prior art. [0004] The present ...
