Description
Technical field
The present invention relates to and a kind of automatically clean, for grouting pipeline in shield engine, the method that blowdown is cleaned in blowdown apparatus and corresponding control thereof.
Background technology
As shown in Figure 1, the slip casting commonly used at present is cleaned drainage and is made up of separate grouting device 1a and blow-off line 2a; This grouting device 1a comprises manual ball valve 11a, mortar tank 12a, organizes the grouting pipeline 13a being connected with mortar tank and the wilkinite filling line 14a for cleaning grouting pipeline more, this grouting pipeline 13a is generally connected and composed through pipeline successively by slip casting jet pipe 131a, slip casting ball valve 132a, slip casting threeway 133a, grouting pump 134a, on this grouting pipeline aforementioned, also side meets a pressure transmitter 135a, for measuring the force value of this grouting pipeline 13a; This grouting pipeline 13a can form separately a branch road and be interconnected (not shown) by board-like ball valve 136a and mortar tank 12a simultaneously, or forms a branch road after grouting pipeline 13a is in parallel be interconnected by board-like ball valve 136a and mortar tank 12a by organizing more; On aforesaid branch road, also side connects one for cleaning the wilkinite filling line 14a of grouting pipeline 13a, and this wilkinite filling line 14a comprises a pneumatic ball valve 141a, a check valve 142a and wilkinite pump 143a; This blow-off line 2a comprises surge pump 21a, foul water tank 22a, sump pump 23a, forms for monitoring the pressure transmitter 24a and some check valve 25a and ball valve 26a of force value in foul water tank, when shield driving distance is shorter from driving ground entrance, can directly by surge pump 21a, the sewage in shield structure directly be discharged outside the entrance of driving ground; Along with the increasing of shield driving distance, then sewage is first introduced foul water tank 22a by surge pump 21a by the sewage in shield structure, after foul water tank 22a precipitates, then being discharged outside driving ground entrance by the sewage in foul water tank 22a by sump pump 23a.
In Shield Construction Method Used process, when grouting pipeline 13a stops slip casting, artificial hammer is needed to beat the board-like ball valve 136a on grouting pump, close this ball valve, then the ball valve 141a being connected with wilkinite is opened, start wilkinite pump 143a to be squeezed into by wilkinite in the pipeline of grouting pipeline 13a and clean, adopt this kind of cleaning way easily to produce four problems:
Problem 1: inject carry out cleaning in the pipeline of grouting pipeline wilkinite easily infiltrate section of jurisdiction outer wall, reduce the viscosity of section of jurisdiction outer wall slurries, the perviousness increasing slurries very easily causes land subsidence;
Problem 2: clean slurries and put into shield body inside, cause the components and parts in shield body to pollute, causes greatly impact easily to shield body internal component severe contamination to equipment repair and maintenance and performance:
Problem 3: generally adopt Artificial Control purging method when grouting pipeline rinses, the time point of flushing is not good to be held, and postpones sometimes to be rinsed by grouting pipeline, easily causes the pipeline frequent jams of grouting pipeline; Also or in advance to grouting pipeline rinse, and cause a large amount of wastes of wilkinite;
Problem 4: easily pile up the solid residue such as some wilkinites and earth mortar in shield structure, need to by manually by its scraper to, in rail car, being delivered to outside driving entrance, labor strength is big.
In view of this, the present inventor furthers investigate for above-mentioned defect of the prior art, then has this case to produce.
