Abstract
The invention relates to a method for filling sand in the pipe laying process after the drilling of a vertical buried pipe heat exchanger in a ground source heat pump system is finished, in particular to a method for filling the sand by raw slurry generated by drilling. The method is realized through the following technical scheme: firstly, a ladder-shaped groove of which the upper part is 2m wide and 2m deep is excavated by a machine, and the groove is excavated on a vertical buried pipe, but the groove is excavated after the pipe laying process before the technology is utilized. The drilling is performed at a drilling position determined in the groove according to a working drawing, and the generated slurry flows into the groove. The pipe is laid after the drilling is finished; gaps between the pipe and the drilled hole are filled by the slurry stored in the groove along with the pipe laying process; and raw slurry self-sink sand filling is completed after the pipe is laid. The process is simple.
Description
Technical field
The invention relates to a kind of method of irritating sand under buried tube heat exchanger boring is accomplished vertically in the earth-source hot-pump system behind the pipe.Especially irritate the method for sand under a kind of being used in that produces former mud of will holing in the pipe process.
Background technique
At present, known buried tube heat exchanger vertically is the core of earth-source hot-pump system, and its quality will be directly connected to the success or failure of whole system, and engineering is in case accomplish and can not repair.Therefore for guaranteeing that ground pipe laying concealed work reaches 100% qualified, unit in charge of construction have overlap pipe laying boring vertically, vertically pipe laying down pipe, arrive the method that the sand location was put, irritated rapidly in finger setting after the pipe degree of depth down.Therefore be provided with the mortar pond, the mud that boring produces is had bad luck away and is waited relevant facility, guarantees with the construction quality that realizes this stage.But this method deficiency is to take up an area of greatlyyer, establishes the mortar pond separately, makes mortar, has bad luck multiple working procedures such as mud and spoil ground, and time-consuming.
Summary of the invention
The present invention has overcome the deficiency of existing technology, provide a kind of not only operation simple and also make things convenient for, saves time, earth-source hot-pump system that expense is low relatively vertically buried tube heat exchanger in pipe process down, accomplish the formula filling sand method of drowning oneself with the former mud that boring produces.
The present invention is achieved through following technical proposals, and said pipe laying excavates this groove vertically with machinery elder generation wide 2 meters dark 2 meters trapezoidal grooves in excavation top, without carrying out behind the pipe down before this technology.The said construction drawing definite bore position place in groove of pressing holes, and the mud that is produced flows in the groove.Manage down after said boring is accomplished, the said mud that is stored in the groove fills up with space between the pipe process will be managed and hole down and tamps, and irritates also i.e. completion of sand with the former mud formula of drowning oneself after following pipe is accomplished, and operation is simple.
Embodiment
Below in conjunction with examples of implementation the present invention is further described:
Press construction plan inspection location unwrapping wire, using machinery afterwards is benchmark with ± 0.000, and length is as the criterion by construction plan; Excavate dark 2 meters groove tops, wide 2 meters trapezoidal grooves set up rig after smooth in the groove and on groove, hole; When boring reaches the designing requirement degree of depth, mention rod bit, it is unloaded to change manage facility pipe down down; In following pipe process; The mud that is stored in groove is irritated sand in space between pipe and the boring, treats down that the pipe facility mentions on groove, and mud all fills up the space and tamps from being sunken between the hole effective under the pipe laying and brill vertically the space.Promptly accomplished earth-source hot-pump system vertically buried tube heat exchanger irritate sand with the magma formula of drowning oneself.
Claims (5)
- In the earth-source hot-pump system vertically buried tube heat exchanger irritate the sand location technology, it is characterized in that starching the formula of drowning oneself with former mud (sand) irritates sand.
- 2. excavate 2 meters wide 2 meters dark trapezoidal grooves earlier with machinery according to claim 1.
- 3. hole like the said construction drawing central position in groove of pressing of claim 2.
- 4. the mud like the said generation of claim 3 flows in the groove.
- 5. accomplish pipe down like the said boring of claim 4 back.Fill up with space between the pipe process will manage and hole down and tamp like the said mud that is stored in the groove of claim 5, completion is starched the formula filling sand of drowning oneself with former mud (sand).
