Description
Technical field
The utility model belongs to the concrete conveyance technical field of tools of architectural engineering deep foundation pit construction.
Background technology
In the deep foundation pit construction of large-scale construction engineering, the conveying capacity of concrete is big, for the project that construction site is narrow, with
The quickening of deep basal pit raft plate construction speed, builder's road is blocked, and concrete tank cannot directly enter during concreting
In deep basal pit, concreting is caused to hinder and influence the duration.If being conveyed using automotive pump, not only pumping takes costliness, in addition
The brachium of automotive pump is limited, it is impossible to cover whole foundation ditch.If conveyed using traditional wood shuttle groove or polyethylene board shuttle groove mixed
Solidifying soil, concrete gliding speed is too fast to cause concrete to isolate, and convey second-rate.In addition, for wood shuttle groove, mixing
Frictional force between solidifying soil and wood shuttle groove is big, and timber wears no resistance, and use time may result in wood chip and is mixed into mixed for a long time
In solidifying soil, and work progress is influenceed by rainy season, easily cracking, warpage, deformation after drenching with rain of exposing to the weather.Polyethylene board shuttle groove
It is pressurized yielding, repair amount is big after deformation, and quality cannot be guaranteed after reparation, and surface is excessively smooth in addition easily makes concrete
Flowing velocity is accelerated and produces serious segregation phenomenon.
The content of the invention
The purpose of this utility model is to solve problem of the prior art there is provided one kind can effectively to solve deep foundation ditch concrete defeated
Send and pour problem, easy construction and the deep foundation ditch concrete means of delivery that can ensure that construction quality.
The purpose of this utility model is achieved through the following technical solutions：
A kind of deep foundation ditch concrete means of delivery, including it is trapezoidal turning shuttle groove, friendship that notch, which is more than the cross section of bottom land,
Mistake is welded in the downward-sloping flow deflector of shuttle groove both sides side plate inwall, is welded in the cover plate at shuttle groove turning；The turning shuttle
Groove is made up of straight shuttle section with the turnaround section for being welded in straight shuttle section bottom, and the angle of turn between straight shuttle section and turnaround section is more than 90 °；
Turning shuttle groove, flow deflector and cover plate are steel plateelement.
Angle between flow deflector upper surface described in the utility model and shuttle groove side plate is 135 °.The outer end of the flow deflector
Face is downward angled end-face.The straight shuttle section of the turning shuttle groove is by being arranged between segmentation connecting structure, adjacent two sections
Connecting plate and connecting bolt outside bottom land and side plate are connected with each other or are welded to each other connection.The cover plate is welded in turning shuttle groove
The bottom of straight shuttle section.
The utility model integrally uses steel plate welding manufacture, and its stabilized structure is unlikely to deform.Between steel plate and concrete
Frictional force is more than the frictional force between polyethylene board and concrete, can mitigate the concrete disintegration phenomenon in conveying, especially will
Shuttle groove is set to turning structure, and the deflector that is staggered in shuttle groove, on the one hand can ensure that concrete is smoothly flowed down, the opposing party
Face can slow down the speed that concrete is flowed down, and thoroughly avoid concrete from not easily causing mortar in course of conveying and produced with aggregate separated
The phenomenon of raw isolation, it is ensured that construction quality.The cover plate set at shuttle groove shuttle groove turning can be prevented effectively from concrete and flow to straight shuttle
Due to speed is fast, impulsive force big, easily splashes and brings potential safety hazard during the lower mouth of section.The utility model is simple in construction, firm
Reliable, reusing is good.Using the utility model, the number of times of plugging when concrete is transported from top to bottom is effectively reduced, it is defeated
Send the speed of concrete fast, effectively shorten the duration, reduce construction cost.Noise pollution during shuttle groove delivering concrete is small, favorably
In environmental protection and energy saving.

Embodiment
Deep foundation ditch concrete means of delivery as shown in Figure 1 and Figure 2, including notch are trapezoidal more than the cross section of bottom land
Turning shuttle groove, staggeredly be welded in the downward-sloping flow deflector 2 of shuttle groove both sides side plate inwall, be welded in the cover plate at shuttle groove turning
3.The turning shuttle groove is made up of straight shuttle section 1a with the turnaround section 1b for being welded in straight shuttle section bottom, the straight shuttle section of the present embodiment and turning
The length ratio of section is 15:1.Angle of turn between straight shuttle section and turnaround section is more than 90 °, the upper surface of flow deflector 2 and shuttle groove side plate
Between angle be 135 °, cover plate 3 is welded in the bottom of turning shuttle groove straight shuttle section.To place the smooth flow for stopping concrete,
The outer face 2a of flow deflector 2 is made into downward angled end-face, as shown in Figure 3.The utility model is all welded with steel plate, is turned
Curved shuttle groove, flow deflector 2 and cover plate 3 are manufactured using the thick steel plates of 5mm.The utility model can be fabricated to general part, turning shuttle groove
Straight shuttle section 1a be to make the structure that segmentation group connects, can make as 4m per segment length, by being arranged between adjacent two sections
Connecting plate outside bottom land and side plate and connecting bolt are connected with each other or by being welded to connect, the straight shuttle segment length of live shuttle groove by
The height of deep basal pit, the gradient of shuttle groove determine that the vertical range of straight shuttle section upper end from the ground is 1200mm, it is ensured that concrete tank
Blanking and in the range of the safe distance on foundation ditch side.
As shown in figure 4, the utility model is installed in deep basal pit 4, the straight shuttle section 1a of shuttle groove is from deep basal pit top droop
Build to apart from deep basal pit bottom certain distance, the straight shuttle section of shuttle groove of the present embodiment is that segmentation is welded.Built at shuttle groove back
There is supporting steel frame 5.
Concrete makes concrete in shuttle groove into S types in straight shuttle section course of conveying by descending conveying of conducting oneself with dignity, flow deflector
Water conservancy diversion, it is to avoid concrete causes mortar and aggregate separated in course of conveying and producing segregation phenomenon causes delivery pump plugging, makes
Concrete conveyance quality obtains Reliable guarantee.Being reduced using the utility model directly use ground pump delivering concrete from top to bottom
And the number of times of plugging, so as to reduce the expense of manual cleaning pump line, construction speed is accelerated, construction cost is reduced.
