Abstract
The utility model discloses a raft board slip casting processing apparatus that comes to nothing includes the outside sleeve pipe of device, sand device and device top apron block water to reach the connecting device with the pump line. The utility model discloses a facilitate to the bottom slip casting of raft board to the slip casting that the quality of assurance slip casting processing that can be fine, these characteristics can be used to after large -scale raft board comes to nothing with the foundation soil is handled.
Description
Technical field
The utility model relates to a kind of injecting treatment device, and especially raft plate comes to nothing injecting treatment device.
Background technology
Pile-raft foundation uses a kind of base form the most general as current building, bearing capacity is high, construction cost is low, structure stability is good, but we can find in Long-Time Service, depart from sometimes bottom raft plate with foundation soil, the reason producing this phenomenon has following 2 points:
(1) in ground, create excess pore water pressure during construction of pile groups, in use procedure afterwards, along with the dissipation of excess pore water pressure, the soil body is consolidation again, and foundation soil and raft plate depart from;
(2) when multi-column pier foundation pile spacing is less, Stress superposition effect is there occurs between adjacent studs, inter-pile soil body subjects the larger vertical compressive stress transmitted by each pile body frictional resistance, produce compressive strain, the compressive strain of deep layer inter-pile soil accumulation, shallow-layer inter-pile soil is in by pile frame dummy status, forms the negative friction to stake.Along with the increase of time, due to the creeping of foundation soil, the rheological equationm of state, shallow-layer inter-pile soil and then sinks, and produces raft plate and descends the phenomenon of coming to nothing of foundation soil with it.
Although in ordinary pile foundation design, we do not consider that foundation soil is to the bearing capacity of superstructure, foundation soil comes to nothing to seem and does not affect building, in fact, in the power transmission process of stake, due to the disengaging of raft plate and foundation soil, have lost a part of pile side resistance, result in the depression of bearing force of stake, the safety of building has been arrived in serious threat, and in order to address this problem, we often adopt the processing scheme to raft plate rising pouring slurry.When raft plate is less, we can in raft panel edges to slip casting below raft plate, due to the development of economic technology, it is increasing that raft plate does, the quality of constructing can not have been ensured in the slip casting of raft panel edges, how to ensure smooth slip casting below raft plate, this is the problem that we urgently will solve now.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of injecting treatment device providing a kind of structure simple, easy to use.
The technical solution adopted in the utility model is: a kind of raft plate comes to nothing injecting treatment device, comprise device outer sleeve, block water sand device and device top blind flange, and and the linkage of pump line, described in block water sand device by draw-in groove sleeve pipe mounted externally.
Described outer sleeve is sectional, and one end is screw thread, and one end is nut, and bushing outer surface is welded with connecting key, ensures to bond preferably with raft board concrete.
Described sealing stops sand device by draw-in groove sleeve pipe mounted externally.
Described pump line linkage is also by draw-in groove sleeve pipe mounted externally.
A kind of raft plate of the utility model comes to nothing injecting treatment device, is used for processing a kind of grouting device that raft plate and foundation soil come to nothing.
Beneficial effect: a kind of raft plate disclosed in the utility model comes to nothing injecting treatment device, before building raft plate, this device is nuzzled in raft plate in advance, if measure raft plate and foundation soil comes to nothing in the use procedure in later stage, injecting treatment can be carried out to raft plate bottom by this device, the utility model for bottom raft plate slip casting provide convenient, and can be good at ensureing the quality of injecting treatment, this feature can be used for large-scale raft plate and foundation soil come to nothing after injecting treatment.
