Abstract

The utility model relates to a combination concrete precast dado for a hole digging pile, which mainly comprises a plurality of sections of circular pipe shape dadoes which are formed by that a plurality of arc-shaped precast tiles are surrounded and a precast pipe with hanging ring. The dadoes are arranged under the precast pipe. The arc-shaped precast tiles in each section of circular pipe shape dado are respectively connected by pothooks with which the lower ends of the precast tiles in an upper section (Precast protection pipes are arranged above a first section) dado are provided. Two adjacent arc-shaped precast tiles in each section of circular pipe shape dado are fixedly connected with a fastening bolt by two fastening steel pieces respectively. The utility model has the characteristics of fast installation in construction, labour saving, time saving and construction safety guarantee.

Description

The assembly type concrete gives the system protection wall of bored pile

The utility model relates to a kind of protection wall of bored pile for building.

In excavation pile construction, the formation of protection wall of bored pile all is after building-site excavates out one section stake hole at present, again support lifting plate, placing of concrete at last.This method under the relatively poor situation of geological conditions, as soil property easily cave in or water layer more shallow, that is seeped water washes away, the more difficult moulding of retaining wall, and, need the regular hour from being poured onto the degree that reaches desirable, therefore, this method both wasted raw material, manpower and time, had potential safety hazard again.

In view of the foregoing, the purpose of this utility model provides a kind of assembly type concrete and gives the system protection wall of bored pile, makes it quick for installation, saves manpower and time, guarantees construction safety.

The purpose of this utility model is achieved in that it comprises that the top has suspension ring, the concrete that the bottom has a hook gives tubulation and places this to give that multistage gives the system watt pipe shape retaining wall that surrounds by the multi-disc arc below the tubulation, being arranged in each the sheet arc that gives kept man of a noblewoman's section pipe shape retaining wall under tubulation system of giving links to each other by being located at the hook that gives the tubulation lower end watt respectively, be arranged in and give secondary segment below the tubulation to each sheet arc of following each section pipe shape retaining wall and give system watt lower end and have respectively with adjacent each sheet of hypomere pipe shape retaining wall and give the system watt hook that links to each other, in each section pipe shape retaining wall adjacent two give the system watt between be connected by two fastening steel discs and a fastening bolt respectively, adjacent two arcs give the system watt the bottom, junction be provided with ooze the slurry hole.During assembling, will give earlier under the tubulation, pass cross bar in the suspension ring so that fixed stake position and guarantee that retaining wall does not sink in the work progress to the position, hole.By hook each sheet arc system of giving watt is hung up giving the tubulation lower end then.Fixed by two fastening steel discs and a fastening bolt between adjacent two arcs system of giving watt, so just form first section pipe shape retaining wall, the system of giving of each the sheet arc up and down in later adjacent two sections pipe shape retaining walls is watt all continuous by hook.When fill concrete ramming pile foundation, slurries can go out by oozing the slurry orifice flow, fill the retaining wall outer void, guarantee bearing capacity.

The utility model has the advantages that: install during construction rapidly, solid and reliable, therefore can adapt to relatively poor geological environment condition, save manpower and time.

Below in conjunction with accompanying drawing the utility model is explained.

Fig. 1 is the utility model structural representation.

Fig. 2 is an I portion zoomed-in view among Fig. 1.

Fig. 3 is an A-A zoomed-in view among Fig. 1.

Fig. 4 is a B-B zoomed-in view among Fig. 1.

By accompanying drawing as can be known, the concrete that has suspension ring 1 gives tubulation 2 and is positioned at its lower end and surrounds first section pipe shape retaining wall by three arcs (cross section is curved) system of giving watts 6, every arc system of giving watt links to each other by being located at the hook 3 that gives tubulation 2 lower ends respectively, adjacent two arcs give the system watt between be connected by two fastening steel discs 4 and a fastening bolt 5, adjacent two arcs give the system watt the lower end, junction be provided with ooze the slurry hole 7, be convenient to slurries and pass, fill the retaining wall outer void.The three arcs system of giving that is arranged in following each section pipe shape retaining wall of first section pipe shape retaining wall watt all by three arcs of epimere pipe shape retaining wall system of giving watt institute be with link up with continuous, the upper end diameter of every section pipe shape retaining wall is less than lower end diameter, making two sections pipe shape retaining wall overlap joins, leave space 8 in this joint, so that filling concrete, strengthen the firm intensity that connects, the three arc system of giving watt dislocation link to each other in the adjacent two sections pipe shape retaining wall, and its error angle is the best with 60 degree.

Claims

1, a kind of combined type concrete gives the system protection wall of bored pile, it is characterized in that: it comprises that the top has suspension ring, the concrete that the bottom has a hook gives tubulation and places this to give that multistage gives the system watt pipe shape retaining wall that surrounds by the multi-disc arc below the tubulation, being arranged in each sheet that gives kept man of a noblewoman's section pipe shape retaining wall under tubulation system of giving links to each other by being located at the hook that gives the tubulation lower end watt respectively, be arranged in and give secondary segment below the tubulation to each sheet arc of following each section pipe shape retaining wall and give system watt lower end and have respectively with adjacent each sheet of hypomere pipe shape retaining wall and give the system watt hook that links to each other, in each section pipe shape retaining wall adjacent two give the system watt between be connected by two fastening steel discs and a fastening bolt respectively, adjacent two arcs give the system watt the bottom, junction be provided with ooze the slurry hole.

2, combined type concrete according to claim 1 gives the system protection wall of bored pile, it is characterized in that: the system of giving of three arcs in the adjacent two sections pipe shape retaining wall watt up and down dislocation links to each other.
