What does culvert D1000 represent

A culvert is 2 meters wide and 2 meters high.

In order not to obstruct traffic, culverts are built under the road surface to allow water to flow under the road and then to the ground, in the shape of pipes, boxes and arches. It is based on the principle of a communicator and is often built of brick, stone, concrete and reinforced concrete. It is a small ground drainage structure that crosses the roadbed when the embankment passes through a depression or crosses a ditch, or to vent the water from above the roadbed to the bottom.

The calculated span l of a single span is less than 5m, and the porous span is less than 8m.

Culverts can be divided into brick culverts, stone culverts, concrete culverts and reinforced concrete culverts according to building materials.

According to the cross-sectional form of culvert, it can be divided into pipe culvert, plate culvert, box culvert and arch culvert.

According to the culvert top fill, it can be divided into open culvert - culvert top no fill and dark culvert - culvert top fill greater than 50cm.

Culverts are divided into non-pressure culverts, semi-pressure culverts and pressure culverts according to their hydraulic properties.

Culverts can be divided into arch culverts, box culverts, round culverts, etc. according to their structure.

When selecting the above-mentioned culvert types, the size of the clearance section, the condition of the foundation, the construction conditions and the project cost are considered.

The part of the culvert structure that can directly affect the catharsis ability of the culvert and ensure the safety of the cave body is the entrance building.

The load on the culvert includes the pressure of the weight of the embankment soil on the culvert and the pressure of the train and vehicle weight transmitted to the culvert through the embankment soil. The top surface of the culvert is subjected to vertical pressure, and the sides are subjected to lateral pressure. The cross-sectional dimensions of each part of it should be determined according to the calculation of the loads listed above.

Standard design drawings are now available for all kinds of culverts.

A culvert is a channel where a road or railway intersects with a ditch to allow water to flow under the road, and has the same function as a bridge, but generally has a smaller aperture and is shaped like a tube, a box and an arch. In addition, a culvert is a cave-like water conservancy facility with sluice gates to regulate the amount of water.

The back of the platform is a construction word, which refers to the bridge and the bottom structure of the bridge is the connection between the bridge and the roadbed.

That is, the culvert needs to be coated with waterproof coating on the back of both sides of the line, and a certain length of transition section is set between the culvert platform and the main body of the roadbed.

The culvert misalignment is mainly to form a flowing slope and keep the culvert stable, but also to facilitate construction. When the slope is not large, in order to avoid the void at the top of the culvert, the height difference of the staggered platform is specified as 3 4 of the thickness of the pipe wall (or cover plate and arch ring).If the slope is steep and the thickness of the pipe wall (cover plate, arch ring) cannot be adjusted, the height difference of the staggered platform can be increased
