Abstract
The utility model provides a static pressure tubular pile that can wear the sand bed and a construction equipment of it is used. Pre -buried in this kind of static pressure of its characterized in that tubular pile have two or many logical water steel pipes, and a plurality of spouts of oriented tubular pile hole water spray on the front end stake point of the static pressure tubular pile that first root buried, the logical water steel pipe of each pipe joint stake when pressing the stake pursue the festival and communicate with each other, is equipped with the water inlet and draws water the mouth on lifting by crane the head of static pressure stake, is linked together with slush pump and centrifugal grit pump respectively, starts slush pump water injection and centrifugal grit pump exhausting water respectively when pressing the stake to bury, makes it to form mud and turn over to circulate and get sand. Like this, we use very little cost: the modified has increased the tubular pile of two or many logical water steel pipes, and can the water injection after the transformation and take out the quick -witted tubular pile pressure head of stake of sand, grouting pump of reuse and a grit centrifugal pump, its application range is expanded widely to the geology forbidden zone that just can let the breakthrough of static pressure tubular pile accompany the sand bed.
Description
Technical field
The construction equipment of this pile-type belongs to building foundation field.A kind ofly can penetrate the Novel static pressure pile tube of layer of sand and the special construction equipment of use thereof and construction method specifically.
Background technology
Static pressure pipe pile is a kind of preformed pile of rising in recent years.Because its pile strength is good, save constructional materials again, bearing capacity is high again, and speed of application is fast again.And after construction, do not need the surface structures that just directly can carry out next step through curing time to construct, thus shorten the duration, reduce construction costs, so promoted rapidly.Blemish in an otherwise perfect thing be that current static pressure pipe pile cannot penetrate layer of sand, and in soil layer, accompany that buried depth does not wait, the layer of sand that do not differ of thickness is common geological phenomenon.This is severely limited with regard to making the application of static pressure pipe pile.
Penetrate layer of sand for enabling static pressure pipe pile and arrive precalculated position, the sand being difficult to compress must be taken out the space vacateed and hold pile tube.Domestic existing employing long spire drilling tool bores the way drawing out the grains of sand the hole in the middle of pile tube.But complex structure and effect bad: draw sand speed slowly, draw sand procedure fault and take place frequently.The technician of our design for this reason, machine-building and construction three units improves through test of many times, develops a set of input cost low, and the fast method of speed of application is as follows:
Summary of the invention
The technical problem that we will solve is: those how taking out rapidly static pressure pipe pile stake end are difficult to be compressed the sand grains being also difficult to press to stake week stratum, enable static pressure pipe pile penetrate layer of sand smoothly, arrive precalculated position.
The method that we solve the problems of the technologies described above is: manufacture a kind of static pressure pipe pile and the construction equipment thereof that can penetrate layer of sand, it is characterized in that: pre-buried two or many water flowing steel pipes in static pressure pipe pile, the front end pile top of first static pressure pipe pile buried is provided with the some spouts to pile tube endoporus water spray, water under high pressure in water flowing steel pipe can be sprayed to pile tube endoporus by spout, when piling continues, the water flowing steel pipe of each pipe joint stake is connected section by section by the cannelure of stake end face, static pressure pipe pile end socket is provided with an intake tunnel, a pumping channel, intake tunnel to be connected with a slush pump by high-pressure water pipe and to connect with water flowing steel pipe in stake, pumping channel to be connected with a centrifugal sand stone pump by drinking-water pipe and to communicate with pile tube endoporus, when piling is buried, open slush pump and centrifugal sand stone pump respectively, make it to form mud reacting cycle and get sand.

Fig. 4 adopts reacting cycle to penetrate the Static Pipe Pile Construction schematic diagram of layer of sand.
In figure: 1. pipe pile end portion pile top, 2. pipe pile end portion steel plate, 3. water flowing (mud) embedded steel tube, 4. concrete filled steel tube wall, 5. prestressed reinforcement, 6. water jet, 7. pile tube end socket, 8. intake tunnel, 9. leakage-proof ring, 10. pumping channel, 11. water inlet slush pumps, 12. draw water gravel pump
Detailed description of the invention
From first segment pile tube press-in soil, namely by the intake tunnel of pile tube pressure head 5 to tube pile high-pressure water filling, water is sprayed by the bottom pile top water jet of first segment pile tube, the soil of press-in pile tube endoporus is cut into mud, mud pit is entered by pressure head pumping channel by the extraction of sandstone centrifugal pump by pile tube endoporus, enter intake tunnel by slush pump again, form reacting cycle.After pile tube enters layer of sand, the mud of ejection carries sand grains and is extracted out by pile tube endoporus, enters the desanding of mud pit precipitation.Circulation is until stake end arrives precalculated position thus.
For ease of lifting and Inlet and outlet water sealing, the steel plate of each root static pressure pipe pile end has a circle groove, pile tube end socket is just stuck in groove, and pile tube end socket of slinging during lifting, just together slings together with pile tube.Prepare two or more pile tube end socket during construction and be convenient to rotation use.Represent now general clipping pressing pile construction process in Fig. 4, when adopting old-fashioned top pressing type pile press, pile tube end socket need only be changed into and having into water (mud) and " the stake compressing head " of smoking sand joint.
In sum, in order to penetrate layer of sand, we only need two or many water flowing steel pipes (prestressed reinforcement of simultaneously holding concurrently uses) pre-buried in pile tube, by to these two or many steel pipe water fillings, (starting is water during piling, injecting with Posterior circle is mud) extract the mud containing sand from pile tube medium pore simultaneously, Drilling by circulation technique during similar holing with slurry wall protection, Reusability after mud sediment desanding.Our increase employs a slush pump, a sandstone centrifugal pump like this, can inhale the pile tube pressure head of sand, just can realize the target that pile tube penetrates layer of sand smoothly, greatly extend the scope of application of tube pile construction after adding transformation in course of exerting pressure slip casting.
