Description
Technical field
The utility model relates to bored pile mud replacement technique, is specifically related to a kind of clear water pressurizer and drilled pile pile foundation secondary pile hole cleaning device.
Background technology
After drilled pile pile foundation puts in place under reinforcing cage, if poured pile base concrete immediately not, dregs in stake hole in mud can precipitate again, cause pile bottom sediment thickness to exceed standard, for guaranteeing carrying out smoothly of filling concrete, must carry out secondary pile hole cleaning, clear hole is the mud of substituting in foramen primum, cascalho in cleaning hole, the relative density, sand factor etc. that reduce to pour into front slurries make its index up to specification.While adopting the conventional slurry method of changing of tradition to carry out clearly hole, because clear water proportion is little compared with mud, the mixing velocity of clear water and mud is slow, causes that hole efficiency is low clearly, consuming time longer.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, the clear water pressurizer that cost is low.
Another object of the present utility model be to provide a kind of efficiency high, can guarantee that clear hole quality meets the drilled pile pile foundation secondary pile hole cleaning device of actual needs.
For reaching above-mentioned purpose, the clear water pressurizer that the utility model provides, comprise a top closure, the unlimited body (3a) in lower end, and on the roof of body (3a), be inserted with two upwardly extending flexible pipes (3b), the diameter of two flexible pipes (3b) is all less than the radius of body (3a), the lower end of flexible pipe (3b) communicates with body (3a), and the length that two flexible pipes (3b) stretch in body (3a) is L, L > 5mm.
Another technical problem to be solved in the utility model is to provide a kind of drilled pile pile foundation secondary pile hole cleaning device, comprise clear water pressurizer (3), described clear water pressurizer (3) comprises a top closure, the unlimited body (3a) in lower end, and on the roof of body (3a), be inserted with two upwardly extending flexible pipes (3b), the diameter of two flexible pipes (3b) is all less than the radius of body (3a), the lower end of flexible pipe (3b) communicates with body (3a), the length that two flexible pipes (3b) stretch in body (3a) is L, L > 5m; One of them flexible pipe (3b) is connected with High Pressure Air Compressor (4), and another flexible pipe (3b) is connected with clear water supply line (5), and the bottom of described body (3a) is connected with the conduit (2) of pile foundation.
Distance at the bottom of the Ju Zhuankong hole, lower end of described conduit is 5～15cm.
The diameter of described body and the internal diameter of conduit are suitable.
The beneficial effects of the utility model are: because the utility model utilizes in clear water pressurizer conductive pipe, inject clear water and compressed air, make the clear water liquid level pressure in conduit be greater than the mud liquid level pressure outside conduit, at the bottom of clear water in conduit will arrive at fast, the disturbance velocity of pile bottom sediment is accelerated, clear water and sediment rapid mixing also form mud, along with the continuous injection of clear water, mud just can dilute and discharge stake hole gradually, until the concentration of mud reaches required standard.So the utility model guarantees the quality of pile, and simple to operate, speed is fast, efficiency is high, simple in structure, cost is low.
Accompanying drawing explanation
Fig. 1 be drilled pile pile foundation secondary pile hole cleaning device described in the utility model structural representation;
Fig. 2 is clear water pressurizer structural representation described in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Clear water pressurizer as shown in Figure 2, comprise a top closure, the unlimited body 3a in lower end, and on the roof of body 3a, be inserted with two upwardly extending flexible pipe 3b, the diameter of two flexible pipe 3b is all less than the radius of body 3a, the lower end of flexible pipe 3b communicates with body 3a, the length that two flexible pipe 3b stretch in body 3a is L, L > 5mm.Length L to flexible pipe 3b limits, and can not come off guaranteeing between flexible pipe 3b root and body 3a.
Drilled pile pile foundation secondary pile hole cleaning device as depicted in figs. 1 and 2, one top closure, the unlimited body 3a in lower end, and on the roof of body 3a, be inserted with two upwardly extending flexible pipe 3b, the diameter of two flexible pipe 3b is all less than the radius of body 3a, the lower end of flexible pipe 3b communicates with body 3a, the length that two flexible pipe 3b stretch in body 3a is L, L > 5mm.One of them flexible pipe 3b is connected with High Pressure Air Compressor 4, and another flexible pipe 3b is connected with clear water supply line 5, and the bottom of described body 3a is connected with the conduit of pile foundation 2.Distance at the bottom of 1 hole, Ju Zhuan hole, lower end of described conduit 2 is 5～15cm, preferably 10cm.
As shown in Figure 1, utilize above-mentioned drilled pile pile foundation secondary pile hole cleaning device to carry out the method in hole clearly, its step is as follows:
The utility model utilizes the clear water pressurizer interior injection clear water of 3 conductive pipe 2 and compressed air, make the clear water liquid level pressure in conduit 2 be greater than the mud liquid level pressure outside conduit 2, at the bottom of clear water in conduit 2 will arrive at fast, the disturbance velocity of pile bottom sediment is accelerated, clear water and sediment rapid mixing also form mud, along with the continuous injection of clear water, mud just can dilute and discharge stake hole gradually.
