Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0013] see Figure 1-3 Shown, a kind of porous box culvert double-deck interchange structure connection well 1, comprises the inline flow box culvert 2 of upper layer and the L shape flow box culvert 3 of lower floor, the inline flow box culvert 2 of upper floor and the lower floor The L-shaped over-current box culvert 3 of the L-shaped over-current box culvert 3 shares the middle partition 4, and a communication hole 41 is set between the upper and lower layers of each hole box culvert on the middle partition 4; one end of the hole of the L-shaped over-current box culvert 3 in the lower layer is closed by The plate 34 is closed.
[0014] Among them, the in-line overcurrent box culv...

The invention discloses a porous box culvert double-layer interchange structure connecting well, which is completely located underground, adopts a double-layer interchange structure and comprises an upper-layer linear overflowing box culvert and a lower-layer L-shaped overflowing box culvert, wherein the linear overflowing box culvert and the L-shaped overflowing box culvert share a middle partition plate; communicating holes corresponding to upper-layer hole culverts and lower-layer hole culverts are formed in the middle partition plate, and the up and down corresponding hole culverts of thelinear overflowing box culvert and the L-shaped overflowing box culvert are communicated; and one end of the L-shaped overflowing box culvert is closed. The connecting well is divided into the upper layer and the lower layer which are in single-hole communication, spatial interchange arrangement is achieved, the arrangement of control gates is reduced on the basis that the functions of the single-layer level-crossing arrangement connecting well are guaranteed, the permanent occupied area needed by arrangement of the control gates is omitted, the investment is saved, the arrangement is reasonable, the construction is convenient, and the management is convenient.
Description
technical field [0001] The invention relates to the technical field of porous box culvert connection wells, in particular to a porous box culvert double-layer interchange structure connection well which is fully underground, has no control gate, can adapt to various water flow directions, and can realize single-hole inspection and maintenance functions. Background technique [0002] For water diversion projects, there are many ways to deliver water pipes, culverts, channels, etc. Among them, for water pipe culverts with closed requirements and low internal pressure, the cast-in-place reinforced concrete box culvert has the characteristics of high overall structural rigidity, good adaptability to soft soil foundation and uneven subsidence of the foundation, and the adjustment of section type It is more convenient, the construction process is simple, the construction quality is easy to guarantee, and the cost is low, so it is widely used. In some water diversion projects, due...
