Abstract
The invention discloses a method for blocking bilge wells. The method comprises the steps that 1, an upstream pipe opening connected with the upstream portion of a sewage pipe network is blocked; 2, a sewage pump is arranged in at least one bilge well for pump drainage of sewage; 3, a blocking bag is manually operated through a long rod on a well mouth of a downstream bilge well, and the blocking bag is placed in a water inlet of the downstream bilge well; 4, the bilge well with the sewage pump is observed, and if the water level in the well drops fast and no sewage continues to flow into the well after all the sewage in the well is pumped out, it is indicated that the water inlet of the downstream bilge well is tightly blocked. The blocking bag is pressed in the water inlet of the downstream bilge well through pressure generated by the siphonic effect, a worker does not need to enter the sewage for operation, and the degree of civilized construction is improved. The blocking bag and a sandbag are both connected with ropes for manual operation so that blocking operation can be carried out again conveniently after primary blocking through the blocking bag fails, the worker does not need to go down into the wells to carry the blocking bag or the sandbag, and time and labor are saved.

The accompanying drawing of this manual is schematic diagram, and aid illustration design of the present invention schematically shows shape and the correlation thereof of each several part.Note that the structure of each parts for the ease of clearly showing the embodiment of the present invention, not according to identical scale between each accompanying drawing.Identical reference marker is for representing identical part.
The method of the shutoff sink hole of an embodiment of the present invention is described below in conjunction with accompanying drawing 1 and Fig. 2, and as the preliminary preparation before jacking construction is carried out in the region that there is sewage network, described sewage network is made up of at least two sink holes be interconnected 1; The upstream sink hole 11 of described sewage network connects the upstream mouth of pipe 2, and the downstream wastewater well 13 of sewage network connects the downstream mouth of pipe 3.In the embodiment shown in fig. 1, sink hole 1 comprises upstream sink hole 11, middle part sink hole 12 and downstream wastewater well 13, and middle part sink hole is communicated with upstream sink hole 11, downstream wastewater well 13 respectively by soil pipe 7.
Method for blocking comprises the following steps:
Step 1, the upstream mouth of pipe 2 that shutoff is connected with the upstream sink hole 11 of sewage network;
Step 2, arranges foul water pump 4 and carries out sewage pump drainage at least one sink hole 1; Sewage is drained into non-jacking construction region by the gutter 41 of foul water pump;
Step 3, manually utilize stock to operate plugging bag 5 at the well head place of downstream wastewater well 13, plugging bag 5 is placed on the water inlet of downstream wastewater well 13, plugging bag 5 is pressed on the water inlet of downstream wastewater well 13 by the pressure utilizing siphonic effect to produce;
Step 4, observes and arranges the sink hole 1 of water pump, as very fast in water level decreasing in well and do not have sewage to continue to flow into the water inlet that downstream wastewater well 13 is described after draining in well shutoff is closely knit.
State in the method for shutoff sink hole of embodiment on the invention, if sink hole is darker, manually be difficult to once utilize stock that plugging bag 5 is placed on the water inlet of downstream wastewater well 13, above-described embodiment is improved further, described plugging bag 5 is connected with for manually-operated rope 51, the sink hole water level decreasing arranging water pump slowly or when substantially not declining, reapposes, until shutoff is closely knit after utilizing rope to be proposed by plugging bag.
State in the method for shutoff sink hole of embodiment on the invention, loosen to prevent plugging bag 5, the water inlet of downstream wastewater well 13 leaks, above-described embodiment is improved further, after step 4, manually utilize stock to operate sandbag at the well head place of downstream wastewater well, utilize sandbag to suppress described plugging bag.
If sink hole is comparatively dark, is manually difficult to once utilize stock that sandbag is suppressed described plugging bag, in a more preferred embodiment, described sandbag is connected with for manually-operated rope, for resetting the position of sandbag.
The method of the shutoff sink hole of the above embodiment of the present invention can also be improved as follows, and after step 4, the water pump indwelling arranged in the sink hole of foul water pump is for subsequent use, returns water accident for reply.
