Description
Technical field
The present invention relates to hand pick formula jacking construction field, particularly a kind of silt particle mud district hand pick formula jacking construction device and method.
Background technique
In recent years, the fast development of wastewater treatment in China engineering, a lot of Urban Underground large diameter pipelines need to pass through the buildings such as avenue, town road, highway or railway, for reducing building damage, reduce the impact on traffic as far as possible, often adopt jacking construction.Because push pipe special construction apparatus expense is high; in most cases adopt hand pick formula jacking construction; and in the implementation process of push pipe; often can run into the soft stratum such as mud, quicksand; because back can not bear the reaction force in jack-in process; bring great difficulty to common hand pick formula jacking construction, even cause the failure of pipe-jacking project.
When hand is under normal circumstances dug formula jacking construction, in the situation that there is no special correcting device, conventionally employing increases jacking resistance or reduces jacking resistance at the different direction of the import of tool pipe, in jack-in process, make the axis of tool pipe change, thereby ensure that follow-up conduit axis conforms to design.But due to the mobility of mud, quicksand, the inlet of tool pipe often collapses automatically, and even quicksand or mud flow to tool pipe, correction difficulty while causing hand pick formula jacking construction, and then cause jacking construction failure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of silt particle mud district hand pick formula jacking construction device and method, can reduce the water content of the work surface soil body, improves the success rate of jacking construction.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of silt particle mud district hand pick formula jacking construction device, comprise tool pipe, between tool pipe and concrete back, be provided with jack, front end at tool pipe is provided with soakaway trench, and a part for soakaway trench is through pipe cap, and another part is positioned at tool pipe, described soakaway trench rear end is open, is provided with multiple water seepage holes on the tube wall of soakaway trench.
Be provided with water seepage hole protective housing in the front of each water seepage hole.
Between tool pipe and jack, be provided with top iron.
Below tool pipe, be provided with sump and draining pump.
Described soakaway trench is positioned at the position near tool pipe bottom.
Described soakaway trench is in tilted layout, and rear end is lower.
Adopt above-mentioned constructing device to carry out a method for silt particle mud district hand pick formula jacking construction, comprise the following steps:
One, a side that faces tool pipe in active well is squeezed into the vertical load-bearing stake of a row;
Two, before load-bearing stake, build back, jack and top iron are installed;
Three, at tool pipe front end inner bottom part, squeeze into one or several soakaway trench, near the tool pipe mouth of pipe, the underground water of the soil body oozes out in advance by soakaway trench, makes the tool pipe mouth of pipe within the scope of precipitation funnel;
Four, stroke of the every jacking of tool pipe, soakaway trench shifts to an earlier date stroke of jacking, guarantees that soakaway trench shifts to an earlier date the pre-jacking soil body, and infiltration in advance is also discharged through sump and draining pump, and work surface soil body water content is reduced;
By above-mentioned steps, realize silt particle mud district hand pick formula jacking construction.
Before step 1, in active well, by rear side, multiple well-points dewatering pipes are set outward with active well, carry out well-points dewatering, the degree of depth of well-points dewatering pipe is greater than the degree of depth of active well.
Described described soakaway trench is in tilted layout, and rear end is lower.
In the time of push pipe downstream, adopt vacuum draw draining at the soakaway trench mouth of pipe.
A kind of silt particle mud provided by the invention district hand pick formula jacking construction device and method, by the front end at tool pipe, soakaway trench is set, by the effect of the catchmenting dewatering of soakaway trench, improve the intensity of the operation soil body, for the operation of hand pick formula push pipe creates favorable conditions.The well-points dewatering pipe arranging, realizes Deep Pumped Wells, reduces the water content of the back position soil body, improves the intensity of this position soil body.The load-bearing stake arranging has further increased the strength of concrete back, so that the reaction at support of carrying jack.On the phreatic line of tool pipe upper half part in artificial formation, top and soil at both sides become dry, and intensity increases to some extent, and the bottom soil body is still under phreatic line, and large improvement does not occur intensity, still lower.Thereby prevented soil body flow entering tool pipe more than soakaway trench, create better excavation environment.And due to tool pipe top and soil at both sides more dry, be convenient on the top of tool pipe front end and both sides increase resistance or the mode of digging to reduce resistance are rectified a deviation in time.Before water seepage hole, set up water seepage hole protective housing, can prevent that soakaway trench and water seepage hole from stopping up at jack-in process.
