Detailed Description
In order to make the structure and the using manner of the present invention clearer, the present invention will be further explained with reference to the attached drawings.
Example (b):
referring to fig. 1 and 2, the embodiment provides a deep foundation pit spring eye gushing water drainage structure, including elevator sump well 1, concrete retaining wall 2 has been under construction along the boundary line in elevator sump well 1, digs between elevator sump well 1 and the farthest end spring eye 5 and is equipped with main drainage ditch 6, and other spring eyes 7 between elevator sump well 1 and the farthest end spring eye 5 dig respectively and are equipped with the secondary escape canal 8 that communicates to main drainage ditch 6, all pre-buried steel pipe 3 that is used for the drainage in main drainage ditch 6 and the secondary escape canal 8.
The bottom in main ditch 6 and the time escape canal 8 all is under construction has bed course 9, and the escape canal both sides are under construction has concrete block 10, and the inboard of bed course 9 upside and concrete block 10 is under construction along the escape canal has cement mortar layer 11, steel pipe 3 is laid on cement mortar layer 11, and the chucking has flitch 12 between the both sides of steel pipe 3 and cement mortar layer 11, and the upper portion lid in escape canal is equipped with apron 13, and the top is backfill soil 14.
During the specific construction, the construction is carried out according to the following steps:
the method comprises the following steps: the method comprises the steps of firstly excavating the deepest water collecting well (an elevator water collecting well 1) in an excavation range, manufacturing a concrete retaining wall 2 with the thickness of 200mm along the side line of the deepest water collecting well, arranging a water suction pump (the model is selected according to the actual water collecting quantity) in a water collecting pit, pre-embedding a steel pipe 3 with the pipe diameter of 110mm at the bottom, forming a screw opening in the inner side of the steel pipe 3, manufacturing a matched seal, and ensuring that the seal is screwed tightly without gaps.
And step two, after other areas are excavated, finding out the water burst position, then carrying out conical excavation on the part of the water burst position, accurately positioning the position of a spring eye, and excavating a main drainage ditch 6 from the position of the concrete retaining wall 2 to find a slope in the direction of the elevator water collecting well 1. The main drainage ditch 6 is connected with the spring holes 5 at the farthest end, and the positions of the other spring holes 7 are respectively dug out secondary drainage ditches 8 to be connected with the main drainage ditch 6 and to find slopes towards the main drainage ditch 6 to form a spring hole water gushing drainage network. The minimum of the depth of the drainage ditch is not less than 400mm (the depth can be adjusted according to the actual water gushing condition and the actual elevation of the spring eye, and the water gushing level of the spring eye is higher than the bottom of the drainage ditch).
Step three, pouring a C15 cushion layer 9 with the thickness of 100mm after the excavation of each drainage ditch is finished, setting the position of a pipe groove by snapping a line, building a 120mm standard brick along the snapping ink line, placing a steel pipe 3 with the diameter of 110mm in the drainage ditch for drainage, connecting the steel pipe 3 in the main drainage ditch 6 with the steel pipe 3 in the secondary drainage ditch 8 by adopting a tee joint, and fixing by using a flange or a hoop. After each steel pipe 3 is connected, the next steel pipe 3 is installed after the good drainage condition is observed.
Step four: after the steel pipes 3 are installed, a cover plate 13 with the thickness of 100mm and a concrete cover plate are arranged above the drainage ditch, layered backfilling is carried out after tight sealing, the thickness of the backfilled soil is not more than 200mm after compaction every time, and the backfilling is carried out from two sides simultaneously, so that the side bricks of the drainage ditch are prevented from collapsing.
Step five: and the conical opening at the position of the spring hole is backfilled by adopting gravel, and the top of the conical opening is filled and leveled. And (3) starting subsequent procedures of construction of a bottom plate cushion layer, water prevention and the like, pouring concrete from all directions to the position of the water collecting pit in a centralized manner, sealing and screwing a water outlet by using a pipeline prepared in advance before pouring the concrete to the water collecting pit, and pouring a water outlet pipe into the concrete after taking out the water suction pump.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
