Abstract
The utility model relates to a kind of new advanced quick blocking structure of foundation ditch drainage well, belongs to building structure construction technical field.The utility model is at the internal reservation pvc pipe of drainage well, and backfill rubble is filtered; Foundation pad is provided with around the well head of drainage well; Well lid is placed on the well head of drainage well, and is fixed on foundation pad by setscrew; Waterproofing course is connected with between described well lid and foundation pad; Described pvc pipe stretches out drainage well by well lid, and pvc pipe passes from steel pipe and connects self priming pump recovery precipitation.The great advantage of this well lid is that the postorders such as drainage well is closed in advance before concreting, concrete water-proof construction is unaffected.Compared with mode of in the past shunting in a well, easy to operate, construction fast, is shunt in a well effective, effectively avoids later stage seepage to occur.
Description
Technical field
The utility model belongs to building structure construction technical field, is specifically related to the advanced quick blocking structure of a kind of foundation ditch drainage well.
Background technology
For meeting sole plate construction requirement, in foundation ditch, drainage well at least should remain to after foundation concrete is built and can close.Close as remained to the later stage, sole plate waterproof can not once survive, and concrete needs secondary to build, and forms constuction joint, there is serious hidden leakage defect.
In prior art, usually directly adopt concrete manhole cover shutoff, on well lid, concreting bed course carries out subsequent handling construction.Downcomer leads to outside building foundation pit below bed course, and in closed process, submersible pump indwelling is in drainage well, cannot take out, and being difficult to change, affecting dewatering effect as damaged.Underplate concrete has built rear enclosed, installs steel plate and adopts expansive concrete to close.Shortcoming is that waterproof slab coiled material disconnects at drainage well position, needs the later stage to overlap, there is hidden leakage defect.
For these reasons, a kind of new advanced quick blocking structure of foundation ditch drainage well of design invention seems particularly necessary.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is: provide a kind of new advanced quick blocking structure of foundation ditch drainage well, adopt this plugging structure, drainage well well head can be closed in advance, while precipitation, carry out the construction of the subsequent handling such as waterproof and sole plate reinforcing bar binding, when building base concrete, close drainage well, easy and simple to handle, effectively avoid sole plate seepage, ensure construction quality and duration.
In order to reach above-mentioned technique effect, the utility model by the following technical solutions:
The advanced quick blocking structure of a kind of foundation ditch drainage well, comprise without sandpipe, described is enclosed within the inwall of foundation ditch drainage well without sandpipe, and the inside without sandpipe is inserted with pvc pipe, and described pvc pipe is inserted into the bottommost of drainage well; Drainage well inside is covered with rubble drainage layer, and described rubble drainage layer is distributed in around pvc pipe; Foundation pad is provided with around the well head of drainage well; Well lid is placed on the well head of drainage well, and is fixed on foundation pad by setscrew; Waterproofing course is connected with between described well lid and foundation pad; Well lid is inserted with steel pipe, and described pvc pipe passes from steel pipe and stretches out drainage well, and described steel pipe opening is by plug shutoff;
Described steel pipe opening adopts plug to tighten;
Described pvc pipe is at least 2, and the number of pvc pipe is consistent with steel pipe number, one for recovering precipitation, remaining is for subsequent use.
Drainage well submersible pump proposes after having built by bed course, and reserved two pvc pipes are to shaft bottom, and backfill rubble fills drainage well.Install and close well lid, pvc pipe passes from steel pipe and connects self priming pump recovery precipitation.Closing well lid adopts expansion bolt to be fixed on foundation pad, and gap adopts rigidity water-proofing material shutoff.Carry out waterproof and reinforcement foundation colligation construction, during construction of waterproof layer and sole plate waterproof once survive.Blocked by pvc pipe when building sole plate concrete, steel pipe opening adopts plug to tighten.As the water yield is comparatively large, steel pipe can be used as Grouting Pipe and uses, and carries out slip casting Seal treatment to drainage well.
Present techniques core is advanced closing, and well head position waterproofing course and sole plate waterproofing course have once been constructed, and sole plate concrete one-time-concreting completes, and without constuction joint, does not need post-processed.Waterproof effect is strengthened by well head rigidity water-proofing material and mouth of pipe extra play.Two steel pipe the using and the reserved, block as PVC or damage replaceable steel pipe opening and recover precipitation; Replaceable high-power self priming pump as larger in the water yield or an increase self priming pump draw water.As plug tighten after still the water yield is comparatively large, steel pipe can be used as Grouting Pipe and uses, and carries out slip casting Seal treatment to drainage well.
The great advantage of this well lid is that the postorders such as drainage well is closed in advance before concreting, concrete water-proof construction is unaffected.Compared with mode of in the past shunting in a well, easy to operate, construction fast, is shunt in a well effective, effectively avoids later stage seepage to occur.
Comprehensive foregoing, the utility model structure is simple, and easy construction, the advantage such as time saving and energy saving, having huge potential market is worth, and is worthy of promotion and application.
Accompanying drawing explanation
Fig. 1 is the advanced quick blocking structural representation of a kind of foundation ditch drainage well;
In figure, 1 is plug, and 2 is steel pipe, and 3 is well lid, and 4 is waterproofing course, bed course based on 5, and 6 is without sandpipe, and 7 is rubble drainage layer, and 8 is pvc pipe.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, the advanced quick blocking structural representation of a kind of foundation ditch drainage well, the advanced quick blocking structure of a kind of foundation ditch drainage well, comprise without sandpipe 6, described is enclosed within foundation ditch drainage well inwall without sandpipe 6, and the inside without sandpipe is inserted with pvc pipe 8, and described pvc pipe 8 inserts the bottommost of drainage well; Drainage well inside is covered with rubble drainage layer 7, and described rubble drainage layer 7 is distributed in pvc pipe 8 around; Foundation pad 5 is provided with around the well head of drainage well; Well lid 3 is placed on the well head of drainage well, and is fixed on foundation pad 5 by setscrew; Waterproofing course 4 is connected with between described well lid 3 and foundation pad 5; Well lid 3 is inserted with steel pipe 2, described pvc pipe 8 passes from steel pipe 2 and stretches out drainage well, and described steel pipe 2 mouthfuls is by plug 1 shutoff;
Drainage well submersible pump proposes after having built by bed course, and reserved two pvc pipes are to shaft bottom, and backfill rubble fills drainage well.Install and close well lid, pvc pipe passes from steel pipe and connects self priming pump recovery precipitation.Closing well lid adopts expansion bolt to be fixed on foundation pad, and gap adopts rigidity water-proofing material shutoff.Carry out waterproof and reinforcement foundation colligation construction, during construction of waterproof layer and sole plate waterproof once survive.Blocked by pvc pipe when building sole plate concrete, steel pipe opening adopts plug to tighten.As the water yield is comparatively large, steel pipe can be used as Grouting Pipe and uses, and carries out slip casting Seal treatment to drainage well.
