Abstract
The invention discloses a construction method of a deep digging pipe. The construction method comprises the following steps: (1) inserting a sleeve into a soil layer along a preset angle by utilizing a pushing device and enabling the sleeve to penetrate into a backfilled soil layer; (2) inserting the deep digging pipe into the sleeve by utilizing the pushing device until the deep digging pipe is inserted into a preset position; (3) digging out the soil in the deep digging pipe and then performing the soil digging operation. The construction method disclosed by the invention has the advantage of creatively changing a technique in which drilling is firstly performed and then the pipe is inserted; the sleeve directly penetrates into the backfilled soil layer under powerful jacking of an excavator, namely from the surface layer to the soft soil layer, the deep digging pipe can continuously deeply penetrate into the preset position along the preset angle under the jacking of the excavator by guidance and restriction effects of the sleeve on the deep digging pipe; the construction time of each deep digging pipe is shortened to be within one minute; the construction efficiency is greatly improved; the construction cost is lowered; moreover, the excavator is a general construction machinery, and the convenience of construction is also improved.
Description
Technical field
The present invention relates to technical field of building construction, particularly relate to one and draw dark pipe construction method.
Background technology
The inclination of building, mainly due to the differential settlement of ground.Differential settlement, normally due to building upper load skewness, causes the subsidiary stress of bearing stratum foundation soil uneven; Bearing stratum foundation soil thickness distribution is uneven, causes different parts soil body chrominance signal to be out of shape; Bearing stratum foundation soil substratum skewness, that causes soil body total compression to be out of shape is uneven; Essential bearing stratum is not selected on same soil layer; Building foundation side digs the reason such as foundation ditch and precipitation and causes.
When building run-off the straight exceeds the scope of permission, normal use can be had a strong impact on, even endanger life and the property safety of user.Therefore, when building run-off the straight, rectification should be carried out to it as early as possible.Application number be 00103377.8 patent of invention disclose a kind of building inclination rectification method, wherein the first step is exactly that then dark pvc pipe is drawn in test to needing the soil layer of soil digging to hole; Then carrying out soil digging operation by water under high pressure is auxiliary, but this drillable length is long, sometimes more than ten rice even twenty or thirty rice is reached, and to ensure that boring can ensure that follow-up pvc pipe inserts, this just increases boring difficulty greatly, causes the increase of construction cost and the prolongation of construction period.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and provide one to draw dark pipe construction method.
The technical scheme adopted for realizing object of the present invention is:
One draws dark pipe construction method, comprises the following steps,
1) utilize ejector apparatus to be inserted by sleeve pipe in soil layer along predetermined angle and make it penetrate back fill course,
2) utilize ejector apparatus to insert in sleeve pipe and deeply draw pipe, and until be inserted into precalculated position,
3) earth deeply drawn in pipe is drawn out and can carry out soil digging operation.
Also comprise sleeve pipe and the step deeply drawing pipe pull-out after having constructed.
Described ejector apparatus is excavator.
Described sleeve pipe and deeply draw pipe and be metal tube.
The described diameter deeply drawing pipe is at 10-30mm.
Described draws the galvanized pipe that pipe is 4 points or 6 points deeply.
Also comprise be fixedly installed on deeply draw pipe upper end hold cover, the described cover end that holds is provided with the universal wheel contacted with described ejector apparatus.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention creatively changes first to hole and descends the technique of pipe again, directly penetrate back fill course at the lower sleeve pipe that holds energetically of excavator, namely top layer is until Soft Soil Layer, utilize sleeve pipe can continue predetermined place deep along predetermined angular under the holding of excavator to the guiding and effect of contraction of drawing dark pipe, within each engineering time of deeply drawing pipe foreshortens to one minute, greatly improve efficiency of construction, reduce construction cost, and excavator is common construction machinery, lifting construction convenience especially.
Accompanying drawing explanation
fig. 1the signal of dark pipe construction method is drawn for of the present invention
figure.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Of the present inventionly draw dark pipe construction method and comprise the following steps,
1) ejector apparatus is utilized along predetermined angle, sleeve pipe 2 to be inserted in soil layer as excavator 1 and make it penetrate the large back fill course of hardness, this sleeve pipe is preferably metal sleeve, it has very strong hardness, adopt tubular structure, when penetrating back fill course, little by resistance, be convenient to insert, wherein, backfill thickness is generally at several meters, impurity in it, as rubble is more, utilize sleeve pipe directly to insert to penetrate, crushing effect is had to it, ensure to insert smoothly, preferably, also comprise be fixedly installed on deeply draw pipe upper end hold cover, the described cover end that holds is provided with the universal wheel contacted with described ejector apparatus.Utilize the setting holding cover universal wheel, lateral force can be weakened as far as possible, realize the jacking of steady predetermined direction.
2) ejector apparatus is utilized, pipe 3 is deeply drawn as excavator inserts in sleeve pipe, and until be inserted into precalculated position, wherein, this draws pipe deeply can connect rear insertion section by section, in general, the described diameter deeply drawing pipe is at 10-30mm, directly can select the galvanized pipe of 4 points or 6 points, namely the tap water supply pipe purchased, because soil layer is softer after back fill course, little by resistance, around the bond stress of soil layer can effectively ensure linearly to be headed into during insertion simultaneously, and protection guiding is carried out by sleeve pipe in outer end, the gap of deeply drawing pipe and sleeve pipe meets inserts smoothly, general at 1-5mm,
3) drawn out by the earth deeply drawing pipe and can carry out soil digging operation to the region a below construction 4, soil digging operation is routine operation, does not repeat them here.Also by sleeve pipe and pipe pull-out can be deeply drawn to recycle after having constructed.
The present invention creatively changes first to hole and descends the technique of pipe again, directly penetrate back fill course at the lower sleeve pipe that holds energetically of excavator, namely sleeve pipe is utilized to penetrate topsoil until Soft Soil Layer, utilize sleeve pipe can continue predetermined place deep along predetermined angular under the holding of excavator to the guiding and effect of contraction of drawing dark pipe, within each engineering time of deeply drawing pipe foreshortens to one minute, greatly improve efficiency of construction, reduce construction cost, and excavator is common construction machinery, lifting construction convenience especially.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
