To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of rainwater rush infiltration structure of soft soil foundation, it is described soft including the greening soil layer being layed at the top of soft soil foundation layer It is equipped at intervals with several in soil base to promote to seep foundation pit, several described rush seep foundation pit and are arranged in the soft soil foundation layer in array Top, the two neighboring rush, which is seeped, is embedded with connecting tube between foundation pit, rushs is seeped in foundation pit filled with promoting infiltration object, the rush The bottom for seeping foundation pit is equipped with the first rush straight down and seeps stake, and described first promotees to extend upwardly to the rush infiltration foundation pit at the top of infiltration stake Interior rush is seeped in object, and the inside of the soft soil foundation layer is inserted into the described first bottom for promoting infiltration stake, and described first promotees to seep the week of stake Collarette is arranged with several second rush and seeps stake, and the described second top for promoting to seep stake connects with the face of slope for promoting infiltration foundation pit The inside of the soft soil foundation layer is inserted into touching, the described second bottom for promoting infiltration stake, if the face of slope for promoting to seep foundation pit is equipped with Dry item promotees sewer, and the bottom end for promoting sewer is intersected in described first and promotees to seep the top of stake.
Preferably, first rush seeps stake and the stake tail of the second rush infiltration stake is tapered.
Preferably, the rush infiltration object is followed successively by metalling, slag layer and sand stone layer from top to bottom, and the metalling is by specification Rubble less than 5mm is laid with, and slag of the slag layer by specification less than 2mm is laid with, and the sand stone layer is by specification Sandstone less than 0.6mm is laid with.
Preferably, the width for promoting sewer is 20-30cm, and the depth for promoting sewer is 10-15cm.
Preferably, the angle promoted between sewer and horizontal plane is 30-60 degree.
Preferably, the horizontal layout for promoting to seep foundation pit is in continuously arranged square.
Compared with prior art, the utility model has the following beneficial effects: a kind of rainwater rush infiltration knot of soft soil foundation Structure seeps foundation pit by the way that several continuously arranged rush are arranged in soft soil foundation layer, and the two neighboring rush is seeped to be buried between foundation pit There is connecting tube to guarantee that surface water mutually circulates, avoid collecting forming runoff, promotees to seep setting first in foundation pit and promote to seep stake, it is several Have it is acclive promote sewer bottom end be intersected in the first rush seep stake top, enable promote sewer bottom end water outlet and first Promote infiltration stake to be well connected, the discharge structure of infiltration stake formation straight down is promoted by rush infiltration object, rush sewer and first, to guarantee whole A System drainage is unimpeded, improves the vertical penetrating power of soft soil foundation layer, effectively facilitates rainwater infiltration, and then cut down earth's surface diameter Stream, it is more succinct that the rainwater of entire soft soil foundation promotees infiltration structure construction, and durability is good, is solving the problems, such as the same of engineering practice When, good economic benefit can be obtained.
