Preferably, pressure monitoring device is set in native storehouse 2, by control move speed and mud hydraulic pressure, makes in native storehouse 2
The pressure of the soil body is maintained in the range of needs, keeps the earth pressure balance between the 2 outside soil body of flase floor 22 and native storehouse.
Embodiment three
In certain engineering, active well W1# well and received well W2# well spacing are from for 350m, caliber Ф 1350mm, buried depth
4.915m.When from W1# well to W2# well jacking construction to 190m, push pipe resistance increases severely, and push pipe is huge, leads to not continue to push up
Into.The bridge pier abolished in the past is encountered through prospecting display push pipe, the power pipe in 220,000 volts of 20 hole is additionally provided with above bridge pier.Because of Ф
1350 push-bench do not have broken pile ability, lead to not jacking construction.
If pulling out push-bench jacking again, periphery pipeline will be disturbed bigger, surface subsidence is big and the construction period is long,
Construction cost is high.Due to cannot achieve and be pulled out to the excavation of bridge pier there are power pipe.
In the engineering, increase an active well between bridge pier and active well, from the bridge pier place of being closer, because of power pipe
Presence, need to control the influence to the periphery soil body, prevent surface subsidence, using combined type push-bench described in embodiment one,
It is removed obstacles at reversed jacking to Φ 1350mm push-bench and completes jointed underground.
In the engineering, which is provided with movable rack 221 and export hole due to being provided with native storehouse 2
231, have superpower underground and removes obstacles ability.The cutter head of mud water balance push bench 1 is located in native storehouse 2, and in jacking, the soil body is by soil
The flase floor 22 in storehouse 2 enters in native storehouse 2, by the further cutting and extruding of 1 cutterhead 11 of mud water balance push bench, it can be achieved that soil
Earth pressure balance between the 22 outside soil body of storehouse 2 and flase floor, and there are mud and water balances for mud water balance push bench 1 itself, therefore
The advantages of earth pressure balance and mud and water balance can be had both, so as to preferably control ground settlement, reach protection surrounding building and
The effect of pipeline.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
